    The previous work on this project was devoted to a study of MIS cells and heterojunction cells with Cu/sub 2/O. In particular the junctions were studied by Auger techniques to detect possible chemical changes at the interface. It was found that some preparation conditions could produce heterojunctions without chemical degradation. In the last quarter, work was initiated on the effect of impurities in the starting Cu on the properties of the Cu/sub 2/O and Cu/sub 2/O solar cells. Methods of measuring diffusion length were explored. In this report a further examination of impurities in the Cu is presented. Some additional details on the CdO/Cu/sub 2/O heterojunction are given. The measurement of diffusion length by a photocurrent method is described and some results are given.

    After a year of operating the G-Van, OPALCO concluded that the company transportation needs were not being met by the G-Van. The previous quarterly report mentioned battery problems with the Solectria (No. 51). This problem is one of reduced range and power and has been determined to be caused by one or more individual monoblock failures. The local Solectria representative and Solectria headquarters personnel have been aware of this unsatisfactory condition and are continuing their attempt to solve it. The Solectria and G-Van continue to be used intermittently by company personnel for errands and engineering trips. Generally, the smaller, compact size of the Solectria make it the most preferred by company drivers. Clearly the G-Van is not selected for use because of its size and weight. It is important to note that the driver dissatisfaction is not related to the fact that it is an electric van, but more its lack of maneuverability.

    The objective of this project is to produce one or more microorganisms capable of removing the organic and inorganic sulfur in coal. The original specific technical objectives of the project were to: clone and characterize the genes encoding the enzymes of the ``4S`` pathway (sulfoxide/sulfone/sulfonate/sulfate) for release of organic sulfur from coal; return multiple copies of genes to the original host to enhance the biodesulfurization activity of that organism; transfer this pathway into a fast-growing chemolithotropic bacterium; conduct a batch-mode optimization/analysis of scale-up variables.

    This is the 23rd technical progress report submitted to the Department of Energy in connection with the cooperative agreement between the DOE and the Ohio Power Company for the Tidd PFBC Demonstration Plant. This report covers the period from October 1, 1992 to December 31, 1992. Major activities during this period involve: (1) The unit was operated for a total of 714 hours (including gas turbine air prewarming). There were seven gas turbine starts, seven bed preheater starts, and seven operating periods with coal fire. The peak gross output of 64 MWH was achieved for the period of 1000 to 1100 hours on November 23, 1992. The longest coal fire was 285 hours beginning at 1211 hours on November 25, 1992. (2) Total gross generation was 24,643, and coal consumption was 11,900 tons. (3) The hot gas clean up system was commissioned. (4) Active end fluidization system to address sparge duct cracking and deformation problem was jointly initiated by ABB carbon, B&W and AEPSC. (5) All testing continued using Plum Run dolomite. This approach was taken as a conservative means to avoid sintering and unit trips which were encountered during the previous two start-ups in September using limestone and (6) monitoring of solid, liquid and gaseous waste streams, as detailed in the operations phase monitoring requirements in the EMP, were performed.

    A novel technique for selectively coagulating and separating coal from dispersed mineral matter has been developed at Virginia Tech. The process, Selective Hydrophobic Coagulation (SHC), has been studied since 1986 under the sponsorship of the US Department of Energy. The SHC process differs from oil agglomeration, shear or polymer flocculation, and electrolytic coagulation processes in that it does not require reagents or additives to induce the formation of coagula. In most cases, simple pH control is all that is required to (i) induce the coagulation of coal particles and (ii) effectively disperse particles of mineral matter. If the coal is oxidized, a small dosage of reagents can be used to enhance the process. The technical work program was initiated on July 1, 1992. Force-distance curves were generated for DDOA Br-coated mica surfaces in water and used to calculate hydrophobicity constants and decay lengths for this system; and a new device for the measurement of water contact angles, similar to the Wilhelmy plate balance, has been built 225 kg samples of Pittsburgh No. 8 and Elkhom No. 3 seam coals were obtained; a static mixer test facility for the study of coagula growth was set up and was undergoing shakedown tests at the end of the quarter; a bench-scale lamella thickener was being constructed; and preliminary coagula/ mineral separation tests were being conducted in a bench-scale continuous drum filter.

    1997-10-14

    The Energy Information Administration (EIA) prepares quarterly short-term energy supply, demand, and price projections for printed publication in January, April, July, and October in the Short-Term Energy Outlook. The details of these projections, as well as monthly updates on or about the 6th of each interim month, are available on the internet at: www.eia.doe.gov/emeu/steo/pub/contents.html. The forecast period for this issue of the Outlook extends from the fourth quarter of 1997 through the fourth quarter of 1998. Values for the fourth quarter of 1997, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the fourth quarter 1997 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. 19 tabs.

    The Quarterly Environmental Data Summary (QEDS) for the fourth quarter of 1997 is prepared in support of the Weldon Spring Site Remedial Action Project Federal Facilities Agreement. The data presented constitute the QEDS. The data were received from the contract laboratories, verified by the Weldon Spring Site verification group and, except for air monitoring data and site KPA generated data (uranium analyses), merged into the data base during the fourth quarter of 1997. Air monitoring data presented are the most recent complete sets of quarterly data. Air data are not stored in the data base and KPA data are not merged into the regular data base. Significant data, defined as data values that have exceeded defined ``above normal`` level 2 values, are discussed in this letter for Environmental Monitoring Plan (EMP) generated data only. Above normal level 2 values are based, in ES and H procedures, on historical high values, DOE Derived Concentration Guides (DCGs), NPDES limits and other guidelines. The procedures also establish actions to be taken in response to such data. Data received and verified during the fourth quarter were within a permissible range of variability except for those which are detailed.

    The planned program falls under wetlands area research related to drilling, production, and transportation of oil and gas resources. Specifically the planned program addresses an evaluation of using cyclocraft to transport drill rigs, mud, pipes and other materials and equipment in a cost effective and environmentally safe manner to support oil and gas drilling and production operations in wetland areas. The cyclocraft is a proven hybrid aircraft that utilizes aerostatic and aerodynamic lift. This type of aircraft has considerable payload capacity, VTOL capability, high controllability, low operating cost, low downwash and high safety. The benefits of using a cyclocraft to transport drill rigs and materials over environmentally-sensitive surfaces would be significant. The cyclocraft has considerable cost and operational advantages over the helicopter. The major activity during the second quarter of 1993 was focussed on completion of Task 4, Preliminary Design. The selected design has been designated H.1 Cyclocraft by MRC. Also during the report period, Task 6, Ground Support, was completed and a report containing the results was submitted to DOE. This task addressed the complete H.1 Cyclocraft system, i.e. it included the need personnel, facilities and equipment to support cyclocraft operations in wetland areas.

    This report summarizes the progress made during the fourth quarter of the research 9 project entitled {open_quotes}A Novel Microorganism for Selective Separation of Coal from Ash and Pyrite{close_quotes}. The objective of this project is to study the effectiveness of a novel hydrophobic microorganism, Mycobacterium phlei (M. phlei), for the selective flocculation of coal from pyrite and ash forming minerals. During the reporting period, the adhesion of M phlei on the surface of quartz was investigated as a function of pH and conditioning time. Results showed that the little adhesion of M phlei onto quartz occurred. The amount of M phlei adsorbed onto the surface of quartz was less compared to coal. These results suggest that it would be possible to flocculate coal selectively from ash forming minerals. Flocculation tests conducted with Illinois No. 6 coal showed that rapid flocculation takes place in the pH range of 3-4. Flocculation efficiency is highly dependent upon the M. phlei concentration.

    This report traces key financial trends in the US energy industry for the fourth quarter of 1993. Financial data (only available for publicly-traded US companies) are included in two broad groups -- fossil fuel production and rate-regulated electric utilities. All financial data are taken from public sources such as energy industry corporate reports and press releases, energy trade publications, and The Wall Street Journal`s Earnings Digest; return on equity is calculated from data available from Standard and Poor`s Compustat data service. Since several major petroleum companies disclose their income by lines of business and geographic area, these data are also presented in this report. Although the disaggregated income concept varies by company and is not strictly comparable to corporate income, relative movements in income by lines of business and geographic area are summarized as useful indicators of short-term changes in the underlying profitability of these operations. Based on information provided in 1993 fourth quarter financial disclosures, the net income for 82 petroleum companies -- including 18 majors -- was unchanged between the fourth quarter of 1992 and the fourth quarter of 1993. An 18-percent decline in crude oil prices resulted in a deterioration of the performance of upstream (oil and gas production) petroleum companies during the final quarter of 1993. However, prices for refined products fell much less than the price of crude oil, resulting in higher refined product margins and downstream (refining, marketing and transport) petroleum earnings. An increase in refined product demand also contributed to the rise in downstream income.

    The Environmental Protection Department/Environmental Monitoring Section (EPD/EMS) administers the Savannah River Site's (SRS) Groundwater Monitoring Program. During fourth quarter 1991, EPD/EMS conducted extensive sampling of monitoring wells. EPD/EMS established two sets of criteria in 1986 to assist in the management of sample results. The flagging criteria do not define contamination levels; instead, they aid personnel in sample scheduling, interpretation of data, and trend identification. Beginning in 1991, the flagging criteria are based on EPA drinking water standards and method detection limits. A detailed explanation of the current flagging criteria is presented in the Flagging Criteria section of this document. Analytical results from fourth quarter 1991 are listed in this report.

    The threat of global warming, mounting concerns about air and water pollution, prospective food shortages, and declining reserves of low-cost fossil fuels, have spawned a burgeoning interest in photobiological processes using microalgae as a method of large-scale utilization of CO{sub 2} for the production of fuels, food, and waste treatment. The major activity during this quarter was the development of cost data for the algal production system, including alternatives to the basic design previously used. The results of this work are still being developed and will be reported in the Final Report. This progress report summarizes a study of a production processes for one specific alga, Botryococcus braunii. This alga is of particular interest in this project as it produces an almost pure hydrocarbon fuel, and does so in rather large amounts. Technology for the production of this organism has, however, not yet been developed. This progress report reviews the literature on this interesting alga and suggests potential methods for its production. 62 refs.

    During the fourth quarter of 1989, over 2700 samples representing more than 5000 analyses and measurements were collected by the Environmental Surveillance and Protection Section. A network of real-time monitoring stations that telemeter 10-min-averaged readings of radiation levels, total precipitation, flows, water quality parameters, and air quality parameters around Oak Ridge National Laboratory (ORNL) also reported data. In addition, three meteorological towers sent weather data at various heights to a host computer every 15 min. Isotopes {sup 3}H, {sup 131}I, {sup 133}I, {sup 135}I, {sup 191}Os, and {sup 212}Pb were the primary isotopes emitted from ORNL stacks during this quarter. Ambient air activity for gross alpha, gross beta, and {sup 131}I was consistent with the previous quarter. The Melton Branch (MB) 1 station continued to show the highest radionuclide concentrations of all the stream locations monitored. A total of 30 noncompliances were associated with the National Pollutant Discharge Elimination System (NPDES) permit. Analysis of Category I and II outfalls for gross beta was initiated this quarter. A total of 264 water samples and 45 sediment samples were collected and analyzed for mercury as part of NPDES activities to characterize and to quantify mercury contamination in the aquatic environment. Water and sediment samples were collected at nine sites. Groundwater samples were collected at waste area grouping (WAG) 1 during this quarter. Data for milk samples from within the immediate environs of ORNL and fish collected in the Clinch River are also presented. 26 figs., 75 tabs.

    During fourth quarter 1992, samples from 18 groundwater monitoring wells of the AMB series at the Metallurgical Laboratory Hazardous Waste Management Facility were analyzed for certain heavy metals, indicator parameters, radionuclides, volatile organic compounds, and other constituents. Six parameters exceeded final Primary Drinking Water Standards (PDWS) and the Savannah River Site Flag 2 criteria during the quarter. The results for fourth quarter 1992 are fairly consistent with the rest of the year`s data. Tetrachloroethylene exceeded the final PDWS in well AMB 4D only two of the four quarters; in the other three wells in which it was elevated, it was present at similar levels throughout the year. Trichloroethylene consistently exceeded its PDWS in wells AMB 4A, 4B, 4D, 5, and 7A during the year. Trichloroethylene was elevated in well AMB 6 only during third and fourth quarters and in well AMB 7 only during fourth quarter. Total alpha-emitting radium was above the final PDWS for total radium in well AMB 5 at similar levels throughout the year and exceeded the PDWS during one of the three quarters it was analyzed for (third quarter 1992) in well AMB 10B.

    Hanford Seismic Monitoring provides an uninterrupted collection of high-quality raw and processed seismic data from the Hanford Seismic Network (HSN) for the U.S. Department of Energy and its contractors. Hanford Seismic Monitoring also locates and identifies sources of seismic activity and monitors changes in the historical pattern of seismic activity at the Hanford Site. The data are compiled, archived, and published for use by the Hanford Site for waste management, Natural Phenomena Hazards assessments, and engineering design and construction. In addition, the seismic monitoring organization works with the Hanford Site Emergency Services Organization to provide assistance in the event of a significant earthquake on the Hanford Site. The HSN and the Eastern Washington Regional Network. (EWRN) consist of 40 individual sensor sites and 15 radio relay sites maintained by the Hanford Seismic Monitoring staff. A major reconfiguration of the HSN was initiated at the end of this quarter and the results will be reported in the first quarter report for next fiscal year (FY2000). For the HSN, there were 390 triggers during the fourth quarter of fiscal year(FY) 1999 on the primary recording system. With the implementation of dual backup systems during the second quarter of the fiscal year and an overall increase observed in sensitivity, a total of 1632 triggers were examined, identified, and processed during this fiscal year. During the fourth quarter, 24 seismic events were located by the HSN within the reporting region of 46 degrees to 47 degrees north latitude and 119 degrees to 120 degrees west longitude 9 were earthquakes in the Columbia River Basalt Group, 2 were earthquakes in the pre-basalt sediments, 10 were earthquakes in the crystalline basement; and 2 were quarry blasts.

    This document provides a report of an analysis of the Radiological Control Program through the fourth quarter of Calendar Year (CY-98) and is the annual report for the Idaho National Engineering and Environmental Laboratory (INEEL). This Performance Indicator Report is provided in accordance with Article 133 of the INEEL Radiological Control Manual. The INEEL collective occupational radiation deep dose is 63.034 person-rem year to date, compared to a goal of 83.1 person-rem. During the fourth quarter, all areas experienced deletions of work resulting from the Maintenance Stand Down. This reduction in work is a primary factor in the difference in the year end dose and the ALARA goal. The work will be completed during CY-99. Beginning in CY-98, a numeric Radiological Performance Index (RPI) is being used to compare radiological performance. The RPI takes into consideration frequency and severity of events such as skin contaminations, clothing contaminations, spills, exposures to radiation exceeding limits, and positive internal dose. The RPI measures the cost of these events in cents per hour of radiological work performed. To make the RPI meaningful, tables have been prepared to show the facility that contributes to the values used. The data are compared on a quarterly basis to the prior year to show measurable performance.

    Free-droplet vaporization experiments with n-tetradecane fuel were conducted during the fourth quarter. Experiments were performed in the temperature range 600 to 1200 C. Impulse-type droplet injection was used to minimize droplet-droplet interaction, ensure complete vaporization, and reduce sooting to a manageable level. The distribution of light pyrolysis products at temperatures less than 800 C was in agreement with the Rice-Kossiakoff radical chain mechanism for hydrocarbon pyrolysis. PAH compounds in the condensed decomposition products were rapidly identified by a retention index scheme. The PAH level in the condensate increased with extent of vaporization and decreased at the onset of sooting. 3 figures, 1 table.

    During fourth quarter 1992, the groundwater at the H-Area Seepage Basins (HASB) was monitored in compliance with South Carolina Hazardous Waste Management Regulations, R61-79.265, Subpart F. Samples were collected from 130 wells that monitor the three separate hydrostratigraphic units that make up the uppermost aquifer beneath the HASB. A detailed description of the uppermost aquifer is included in the Resource Conservation and Recovery Act Part B Post-Closure Care Permit Application for the H-Area Hazardous Waste Management Facility submitted to the South Carolina Department of Health and Environmental Control in December 1990. Historically, as well as currently, tritium, nitrate, total alpha-emitting radium, gross alpha, and mercury have been the primary constituents observed above final Primary Drinking Water Standards (PDWS) in groundwater at the HASB. Isoconcentration/isoactivity maps included in this report indicate both the concentration/activity and extent of the primary contaminants in each of the three hydrostratigraphic units during first and fourth quarter 1992. Water-level maps indicate that the groundwater flow rates and directions at the HASB have remained relatively constant since the basins ceased to be active in 1988.

    The Saltstone Facility is designed and permitted to immobilize and dispose of low-level radioactive and hazardous liquid waste (salt solution) remaining from the processing of radioactive material at the Savannah River Site. Low-level waste (LLW) streams from the Effluent Treatment Project (ETP), H-Canyon, and the decontaminated salt solution product from the Actinide Removal Process/Modular Caustic Side Solvent Extraction (CSSX) Unit (ARP/MCU) process are stored in Tank 50 until the LLW can be transferred to the Saltstone Facility for treatment and disposal. The LLW must meet the specified waste acceptance criteria (WAC) before it is processed into saltstone. The specific chemical and radionuclide contaminants and their respective WAC limits are in the current Saltstone WAC. Waste Solidification Engineering (WSE) requested that Savannah River National Laboratory (SRNL) perform quarterly analysis on saltstone samples. The concentrations of chemical and radionuclide contaminants are measured to ensure the saltstone produced during each quarter is in compliance with the current WAC. This report documents the concentrations of chemical and radionuclide contaminants for the 2011 Fourth Quarter samples collected from Tank 50 on October 12, 2011 and discusses those results in further detail than the previously issued results report.

    The Environmental Sciences Section (ESS) established a quarterly monitoring program of the Four Mile Creek seepline down gradient from the F- and H-Area seepage basins. The program surveys and tracks changes in tritium, specific conductivity, and pH for the seepline water. Measurements from the fourth quarter survey (March/April 1993) showed lower tritium and conductivity measurements and higher pH values (pH 5--6) than measurements from previous studies. The results of the first four quarterly surveys suggest that infiltration of rainfall may be diluting and flushing the contaminants from the groundwater system. More measurements are needed to confirm these trends.

Eighty-five wells provided samples from the three hydrostratigraphic units that make up the uppermost aquifer beneath the FASB. A detailed description of the uppermost aquifer is included in the Resource Conservation and Recovery Act Part B Post-Closure Care Permit Application for the F-Area Hazardous Waste Management Facility submitted to the South Carolina Department of Health and Environmental Control in December 1990. Historically, as well as currently, tritium, nitrate, gross alpha, total alpha-emitting radium, cadmium, and lead are the primary constituents observed above final Primary Drinking Water Standards (PDWS) in groundwater at the FASB. Nonvolatile beta has consistently exceeded its drinking water screening level. Other radionuclides and hazardous constituents also have exceeded the final PDWS in the groundwater at the FASB. The elevated constituents are found primarily in Aquifer Zone IIB{sub 2} (Water Table) and Aquifer Zone IIB{sub 1}, (Barnwell/McBean) wells. However, several Aquifer Unit IIA (Congaree) wells also contain elevated levels of constituents, primarily tritium. Isoconcentration/isoactivity maps included in this report indicate both the concentration/ activity and extent of the primary contaminants in each of the three hydrostratigraphic units for first and fourth quarters 1992. Water-level maps indicate that the groundwater flow rates and directions at the FASB have remained relatively constant since the basins ceased to be active in 1988.

    The Environmental Science and Research Foundation conducts the Offsite Environmental Surveillance Program at the US Department of Energy's Idaho National Engineering and Environmental Laboratory (INEEL). The Foundation's environmental surveillance program monitors the effects, if any, of US Department of Energy (DOE) activities on the offsite environment, collects data to confirm compliance with applicable environmental laws and regulations, and observes any trends in the environmental levels of radioactivity. This report for the fourth quarter 1998 is based on 622 samples collected of air, fine particulates, atmospheric moisture, precipitation, water, milk, potatoes, and game animals. All concentrations of radioactivity found in these samples were consistent with concentrations which have been found in sampling during recent quarters and which have been attributed in the past to natural background radioactivity, worldwide fallout from past nuclear weapons testing, an! d nuclear operations around the world. No measured concentrations could be directly attributed to operations at the INEEL, although statistical differences did exist between on-site and distant gross beta concentrations. No evidence could be found to link these differences with a specific INEEL source. Concentrations in all samples were below the guidelines set by both the DOE and the US Environmental Protection Agency (EPA) for protection of the public.

    The Saltstone Facility is designed and permitted to immobilize and dispose of low-level radioactive and hazardous liquid waste (salt solution) remaining from the processing of radioactive material at the Savannah River Site. Low-level waste (LLW) streams from the Effluent Treatment Project (ETP), H-Canyon, the DDA (Deliquification, Dissolution, and Adjustment) process, and the decontaminated salt solution product from the Actinide Removal Process/Modular Caustic Side Solvent Extraction (CSSX) Unit (ARP/MCU) process are stored in Tank 50 until the LLW can be transferred to the Saltstone Facility for treatment and disposal. The LLW must meet the specified waste acceptance criteria (WAC) before it is processed into saltstone. The specific chemical and radionuclide contaminants and their respective WAC limits are listed in the current Saltstone WAC. SRS Liquid Waste Operations (LWO) requested that Savannah River National Laboratory (SRNL) perform quarterly analysis on saltstone samples. The concentrations of chemical and radionuclide contaminants are measured to ensure the saltstone produced during each quarter is in compliance with the current WAC. This report documents the concentrations of chemical and radionuclide contaminants for the 2009 Fourth Quarter samples collected from Tank 50 on October 2, 2009 and discusses those results in further detail than the previously issued results report. This report details the chemical and radionuclide contaminant results for the characterization of the 2009 Fourth Quarter sampling of Tank 50 for the Saltstone Waste Acceptance Criteria (WAC). Information from this characterization will be used by Liquid Waste Operations (LWO) to support the transfer of low-level aqueous waste from Tank 50 to the Salt Feed Tank in the Saltstone Facility in Z-Area, where the waste will be immobilized. This information is also used to update the Tank 50 Waste Characterization System. The following conclusions are drawn from the analytical results

    This report details the chemical and radionuclide contaminant results for the characterization of the 2013 Fourth Quarter sampling of Tank 50 for the Saltstone Waste Acceptance Criteria (WAC) in effect at that time. Information from this characterization will be used by DWPF & Saltstone Facility Engineering (DSFE) to support the transfer of low-level aqueous waste from Tank 50 to the Salt Feed Tank in the Saltstone Facility in Z-Area, where the waste will be immobilized. This information is also used to update the Tank 50 Waste Characterization System. The following conclusions are drawn from the analytical results provided in this report: SRR WAC targets or limits were met for all analyzed chemical and radioactive contaminants unless noted in this section. {sup 59}Ni, {sup 94}Nb, {sup 247}Cm, {sup 249}Cf, and {sup 251}Cf are above the requested SRR target concentrations. However, they are below the detection limits established by SRNL. Norpar 13 and Isopar L have higher detection limits compared with the Saltstone WAC. The data provided in this report is based upon the concentrations in the sub-sample, and due to the limited solubility of these materials in aqueous solution, may not represent the concentrations of the analytes in Tank 50. The low insoluble solids content increases the measurement uncertainty for insoluble species. The semivolatile organic analysis (SVOA) method employed in the measurement of Norpar 13 and tributyl phosphate (TBP) has resulted in the erroneous reporting of a variety of small chain alcohols, including 4-methyl-3-hexanol and 5-methyl-3-hexanol, in previous quarterly sample reports. It has now been determined that these alcohols are an artifact of the sample preparation. Further work is being conducted in SRNL to delineate the conditions that produce these alcohols, and these findings will be reported separately.

This is not a WAC analyte, but it is the first time this organic compound has been detected in a quarterly WAC sample from Tank 50. (4) The reported detection limit for Norpar 13 is greater than the limit from Table 4 and Attachment 8.2 of the WAC. (5) The reported detection limit for Isopar L is greater than the limit from Table 3 of the WAC. (6) Isopar L and Norpar 13 have limited solubility in aqueous solutions making it difficult to obtain consistent and reliable sub-samples. The values reported in this memo are the concentrations in the sub-sample as detected by the GC/MS; however, the results may not accurately represent the concentrations of the analytes in Tank 50.

    2014-09-30

    This report details the chemical and radionuclide contaminant results for the characterization of the 2012 Fourth Quarter sampling of Tank 50 for the Saltstone Waste Acceptance Criteria (WAC).1 Information from this characterization will be used by Waste Solidification Engineering (WSE) to support the transfer of low-level aqueous waste from Tank 50 to the Salt Feed Tank in the Saltstone Facility in Z-Area, where the waste will be immobilized. This information is also used to update the Tank 50 Waste Characterization System. The following conclusions are drawn from the analytical results provided in this report: The concentration of the reported chemical and radioactive contaminants were less than their respective WAC Limits and Targets, unless noted in this section. Norpar 13 and Isopar L have higher detection limits5 compared with the Saltstone WAC1. The data provided in this report is based upon the concentrations in the sub-sample, and due to the limited solubility in aqueous solution, may not represent the concentrations of the analytes in Tank 50. Diisooctyl adipate (or diisooctyl hexanedioate) was measured at 1.30E+00 mg/L in one of two replicate measurements conducted on an at-depth sample.a The organic analysis of the at-depth sample was conducted at the request of SRR.4 This analyte was below the detection limit in the surface sample. The low insoluble solids content increases the measurement uncertainty for insoluble species.

    The Site Operator Program was initially established by the Department of Energy (DOE) to incorporate the electric vehicle activities dictated by the Electric and Hybrid Vehicle Research, Development and Demonstration Act of 1976. In the ensuing years, the Program has evolved in response to new legislation and interests. The Program currently includes twelve sites located in diverse geographic, metrologic, and metropolitan areas across the US. Information is shared reciprocally with a thirteenth site, not under Program contract. The vehicles are operator-owned, except for two Griffon vans. The Mission Statement of the Site Operator Program includes three major activities: advancement of electric vehicle technologies; development of infrastructure elements necessary to support significant electric vehicle use; and increasing the awareness and acceptance of electric vehicles (EVs) by the public. The current participants in the Site Operator Program are shown. The ultimate thrust of program activities varies among sites, reflecting not only the Operator`s business interests but also geographic and climate-related operating conditions. This fourth quarter report (FY-94) includes a summary of activities from the previous three quarters. The report section sequence has been revised to provide a more easily seen program overview, and specific operator activities are now found in Appendix A.

    The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated on a small scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant. Although an oil shale batch sample is sealed in the batch kiln from the start until the end of the run, the process conditions for the batch are the same as the conditions that an element of oil shale would encounter in a continuous process kiln. Similar chemical and physical (heating, mixing) conditions exist in both systems. The two most important data objectives in this phase of the project are to demonstrate (1) that the heat recovery projected for this project is reasonable and (2) that an oil shale kiln will run well and not plug up due to sticking and agglomeration. The following was completed and is reported on this quarter: (1) A software routine was written to eliminate intermittently inaccurate temperature readings. (2) We completed the quartz sand calibration runs, resolving calibration questions from the 3rd quarter. (3) We also made low temperature retorting runs to identify the need for certain kiln modifications and kiln modifications were completed. (4) Heat Conductance data on two Pyrolysis runs were completed on two samples of Occidental oil shale.

    This fourth Oil Bypass Filter Technology Evaluation report details the ongoing fleet evaluation of an oil bypass filter technology by the Idaho National Engineering and Environmental Laboratory (INEEL) for the U.S. Department of Energy’s FreedomCAR & Vehicle Technologies Program. Eight four-cycle diesel-engine buses used to transport INEEL employees on various routes have been equipped with oil bypass filter systems from the puraDYN Corporation. The bypass filters are reported to have engine oil filtering capability of <1 micron and a built-in additive package to facilitate extended oil-drain intervals. To date, the eight buses have accumulated 259,398 test miles. This represents an avoidance of 21 oil changes, which equates to 740 quarts (185 gallons) of oil not used or disposed of. To validate the extended oil-drain intervals, an oil-analysis regime evaluates the fitness of the oil for continued service by monitoring the presence of necessary additives, undesirable contaminants, and engine-wear metals. For bus 73450, higher values of iron have been reported, but the wear rate ratio (parts per million of iron per thousand miles driven) has remained consistent. In anticipation of also evaluating oil bypass systems on six Chevrolet Tahoe sport utility vehicles, the oil is being sampled on each of the Tahoes to develop a characterization history or baseline for each engine.

    During the second half of 1993, the groundwater at the H-Area Seepage Basins (HASB) was monitored in compliance with the September 30, 1992, modification of South Carolina Hazardous Waste Permit SC1-890-008-989. A detailed description of the uppermost aquifer is included in the Resource Conservation and Recovery Act Part B post-closure care permit application for the H-Area Hazardous Waste Management Facility submitted to the South Carolina Department of Health and Environmental Control (SCDHEC) in December 1990. Beginning first quarter 1993, the HASB`s Groundwater Protection Standard (GWPS), established in Appendix 3D-A of the cited permit, became the standard for comparison. Historically as well as currently, nitrate, nonvolatile beta, and tritium have been among the primary constituents to exceed standards. Other radionuclides and hazardous constitutents also exceeded the GWPS in the groundwater at the HASB (notably aluminum, iodine-129, strontium-90, technetium-99, and zinc) during the second half of 1993. Elevated constituents were found primarily in Aquifer Zone 2B{sub 2} and in the upper portion of Aquifer Zone 2B{sub 1}. However, constituents exceeding standards also occurred in several wells screened in the lower portion of Aquifer Zone 2B{sub 1} and Aquifer Unit 2A. Isoconcentration/isoactivity maps include in this report indicate both the concentration/activity and extent of the primary contaminants in each of the three hydrostratigraphic units during the second half of 1993. Water-level maps indicate that the groundwater flow rates and directions at the HASB have remained relatively constant since the basins ceased to be active in 1988.

    During the second half of 1993, the groundwater at the F-Area Seepage Basins (FASB) was monitored in compliance with Module 3, Section C, of South Carolina Hazardous Waste Permit SC1-890-008-989, effective November 2, 1992. The monitoring well network is composed of 87 FSB wells screened in the three hydrostratigraphic units that make up the uppermost aquifer beneath the FASB. A detailed description of the uppermost aquifer is included in the Resource Conservation and Recovery Act Part B post-closure care permit application for the F-Area Hazardous Waste Management Facility submitted to the South Carolina Department of Health and Environmental Control (SCDHEC) in December 1990. Beginning in the first quarter of 1993, the standard for comparison became the SCDHEC Groundwater Protection Standard (GWPS) specified in the approved F-Area Seepage Basins Part B permit. Currently and historically, gross alpha, nitrate, nonvolatile beta, and tritium are among the primary constituents to exceed standards. Numerous other radionuclides and hazardous constituents also exceeded the GWPS in the groundwater at the FASB during the second half of 1993, notably aluminum, iodine-129, and zinc. The elevated constituents are found primarily in Aquifer Zone 2B{sub 2} and Aquifer Zone 2B{sub 1} wells. However, several Aquifer Unit 2A wells also contain elevated levels of constituents. Isoconcentration/isoactivity maps included in this report indicate both the concentration/activity and extent of the primary contaminants in each of the three hydrostratigraphic units. Water-level maps indicate that the groundwater flow rates and directions at the FASB have remained relatively constant since the basins ceased to be active in 1988.

    The Northeast Regional Biomass Program has been in operation for a period of nine years. During this time, state managed programs and technical programs have been conducted covering a wide range of activities primarily aim at the use and applications of wood as a fuel. These activities include: assessments of available biomass resources; surveys to determine what industries, businesses, institutions, and utility companies use wood and wood waste for fuel; and workshops, seminars, and demonstrations to provide technical assistance. In the Northeast, an estimated 6.2 million tons of wood are used in the commercial and industrial sector, where 12.5 million cords are used for residential heating annually. Of this useage, 1504.7 mw of power has been generated from biomass. The use of wood energy products has had substantial employment and income benefits in the region. Although wood and woodwaste have received primary emphasis in the regional program, the use of municipal solid waste has received increased emphasis as an energy source. The energy contribution of biomass will increase as potentia users become more familiar with existing feedstocks, technologies, and applications. The Northeast Regional Biomass Program is designed to support region-specific to overcome near-term barriers to biomass energy use.

    The Safety Metrics Indicator Program (SMIP) retrieved 44 packaging- or transportation-related occurrences from the Occurrence Reporting and Processing System (ORPS) during the period from July 1 through September 30, 2001. Only those incidents that occur in preparation for transport, during transport, and during unloading of hazardous material are considered as packaging- or transportation-related occurrences. Other incidents with packaging and transportation (P and T) significance but not involving hazardous material (such as vehicle accidents or empty packagings) are not rated to the SMIP criteria, but are archived in the SMIP Subsidiary Database of occurrences, a sub-database of the main SMIP P and T Occurrence Database. Thirty-two of the originally-selected 44 occurrences were appropriate for classification to the SMIP criteria, only 7 of which have offsite applicability. Eight of the original 44 reports are archived in a subsidiary database because they either do not involve the transport of hazardous material or do not involve transport by vehicle, plane, boat, or rail. The others either were deleted because more thorough review revealed that they were not strictly related to P and T or were canceled by the reporting site and removed from the ORPS. These occurrences have not been normalized as in the Annual Report of Occurrences because the necessary information is not yet available. The number and severity of the selected occurrence reports (ORs) are consistent with historical reporting. Contamination events continue to be among the most common type of occurrences; however, ''Shipping Preparation'' events decreased this quarter to only 4 events from the 21 reported last quarter. None of the 32 ORs that were rated had event consequence measures (W{sub EC}) greater than 2; 14 of them were categorized as having a W{sub EC} of 1. This means that all of the fourth-quarter FY 2001 ORs had only slight consequences at worst (i.e., resulting in minimal safety

    Examination of the paleoenvironmental and geomorphic records to determine the local and regional impact of past climates will advance the assessment of Yucca Mountain`s suitability as a high-level nuclear waste repository. Paleobotanical studies will reconstruct the response of vegetation to climate change at the community and the organismal levels in order to identify periods of mesic climate at Yucca Mountain and the adjacent region during the last 20,000 to 50,000 years. Constructing a history of Great Basin vertebrates, particularly mammals, will provide empirical evidence of past environmental and climatic conditions within the Great Basin. The objective of the geomorphology component of the program is to document the responses of surficial processes and landforms to the climatic changes documented by studies of packrat middens, pollens, and faunal distributions. The goal of the transportation component is to compare the results from three models (FESWMS-2DH, DAMBRK, and FLO-2D) that have been suggested as appropriate for evaluating flood flows on alluvial fans with the results obtained from the traditional one-dimensional, stochastic model used in previous research for the Yucca Mountain Project. Progress on all these tasks is described.

    The goal of the West Hackberry Tertiary Project is to demonstrate the technical and economic feasibility of combining air injection with the Double Displacement Process for tertiary oil recovery. The Double Displacement Process is the gas displacement of a water invaded oil column for the purpose of recovering oil through gravity drainage. The novel aspect of this project is the use of air as the injection fluid. The target reservoir for the project is the Camerina C-1,2,3 sand located on the West Flank of West Hackberry Field in Cameron Parish, Louisiana. If successful, this project will demonstrate that the use of air injection in the Double Displacement Process can economically recover oil in reservoirs where tertiary oil recovery is presently uneconomic. The first quarter of 1996 was outstanding both in terms of volume of air injected and low cost operations. More air was injected during this quarter than in any preceding quarter. The compressors experienced much improved run time with minimal repairs. Low operating costs resulted from no repairs required for injection or production wells. A discussion of the following topics are contained herein: (1) performance summary for the injection and production wells, (2) air compressor operations, (3) updated bottom hole pressure data, (4) technology transfer activities and (5) plans for the upcoming quarter.

    Isolated fourth ventricle is not uncommon in complex posthemorrhagic or postinfectious hydrocephalus. When the condition is symptomatic, the current surgical treatment is endoscopic aqueductoplasty, followed by endoscope-assisted placement of a catheter in the fourth ventricle. The authors suggest a very simple method of steering the tip of standard ventricular catheters by using materials commonly available in all operating rooms. The main advantage of this method is that it permits less invasive transaqueductal drainage of trapped fourth ventricles, especially in cases of narrow third ventricle, because the scope and catheter are introduced in sequence and not in a double-barreled fashion. Two illustrative cases are reported.

    Miller, R.L.

    1991-12-31

    This report describes work completed during the fourth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. This work is part of a larger effort to develop a new coal liquefaction or coal/oil coprocessing scheme consisting of three main process steps: (1) mile pretreatment of the feed coal to enhance dissolution reactivity and dry the coal, (2) low severity thermal dissolution of the pretreated coal to obtain a very reactive coal-derived residual material amenable to upgrading, and (3) catalytic upgrading of the residual products to distillate liquids.

    This report summarizes the progress of the Solvent Refined Coal (SRC) project at the SRC Pilot Plant in Fort Lewis, Wahsington, and the Process Development Unit (P-99) in Harmarville, Pennsylvania. After the remaining runs of the slurry preheater survey test program were completed January 14, the Fort Lewis Pilot Plant was shut down to inspect Slurry Preheater B and to insulate the coil for future testing at higher rates of heat flux. Radiographic inspection of the coil showed that the welds at the pressure taps and the immersion thermowells did not meet design specifications. Slurry Preheater A was used during the first 12 days of February while weld repairs and modifications to Slurry Preheater B were completed. Two attempts to complete a material balance run on Powhatan No. 6 Mine coal were attempted but neither was successful. Slurry Preheater B was in service the remainder of the quarter. The start of a series of runs at higher heat flux was delayed because of plugging in both the slurry and the hydrogen flow metering systems. Three baseline runs and three slurry runs of the high heat flux program were completed before the plant was shut down March 12 for repair of the Inert Gas Unit. Attempts to complete a fourth slurry run at high heat flux were unsuccessful because of problems with the coal feed handling and the vortex mix systems. Process Development Unit (P-99) completed three of the four runs designed to study the effect of dissolver L/D ratio. The fourth was under way at the end of the period. SRC yield correlations have been developed that include coal properties as independent variables. A preliminary ranking of coals according to their reactivity in PDU P-99 has been made. Techniques for studying coking phenomenona are now in place.

This report covers the period of work completed during the Second Quarter of CY 1992. Activities included: The Tidd combustor internals were modified to connect the hot gas system for slipstream operation; Various pre-operational activities were completed, including pneumatic leak testing of the HGCU system, operation of the closed cycle cooling water system, operation of the back pulse compressor and air preheater, and checkout of the back pulse skid. Initial operation of the system using the bypass cyclone occurred during May 21--23, 1992; On May 23, 1992, an expansion joint ruptured, forcing the unit to be shut down. The failure was later determined to be due to stress corrosion. Following the expansion joint failure, a complete engineering review of the system was undertaken and is continuing; Contract Modification No. 6 was issued to Westinghouse during this quarter. This modification is for APF surveillance testing services; A purchase order was issued to Battelle for ash sampling hardware and testing services.

    Kansas State University, in support of a DOE and Kansas Electric Utilities Research Program subject contract, continues to test, evaluate, demonstrate, and develop electric vehicle and infrastructure technology. K-State is operating two Soleq EVcort vehicles. During this reporting period both vehicles were brought back to full operational status after warranty service was completed by Soleq. Vehicle failures occurred due to three unrelated battery cable failures in addition to the replacement of one battery. Both vehicles are being operated on a routine basis. K-State, along with York Technical College, has established a relationship with Troy Design and Manufacturing (TDM) Redford, Michigan. K-State has ordered no less than four Ford Ranger electric trucks from TDM. K-State is involved in the steering committee that is monitoring and refining information to direct the design and testing of these new technology vehicles. TDM should become the first automotive manufacturer certified by one of the Big Three under their Quality Vehicle Manufacturer program. Kansas State University and the Kansas Electric Utility Research Program look forward to working with TDM on their new EV program.

    The authors have identified a moldable graphite blend separator plate material, have molded complex shape bipolar separator plates, have tested the molded plate properties and function in single fuel cells, and have designed a conceptual rapid manufacturing line. In this quarter, the project received a three-month interim funding period to continue progress while the proposal is in DOE review. Thus, this fourth quarterly report is submitted in place of the originally scheduled final report for this project. All of the objectives of this project have been accomplished. Specifically, the electrical, chemical, and physical properties of the molded separator plates have met or exceeded the DOE specifications. Performance and endurance tests of the molded plates in single cells have shown comparable performance to the state-of-art machined graphite separator plates. The DOE cost target of $10 per kW appears to be achievable with the low cost composite materials.

    1995-02-01

    The purpose of this contract is to develop a process for converting light alkane gases to methyl chloride via oxyhydrochlorination using highly selective, stable catalysts in fixed-bed reactors designed to remove the large amount of heat generated, so as to control the reaction temperature. Further, the objective is to obtain the engineering data base necessary for developing a commercially feasible process and to evaluate t economics of the process. Significant progress was made in six different technical areas during this quarter. These key highlights are: (1) Evaluation of catalyst samples from UCI led to the ordering of the OHC PDU catalyst batch. This catalyst batch arrived, was screened and found to be defective, and was reordered. (2) Natural gas containing higher hydrocarbons was used as a methane source. The reactant mixture formed oxygenates at temperatures lower than observed in the past. Burning at such low temperatures seems to create a product stream containing very little CH{sub 2}Cl{sub 2}. (3) Although it has not been decided if the PDU will use natural gas from the plant or methane or natural gas from cylinders as a methane feed source, it was concluded that an adsorption unit to remove sulfur and higher hydrocarbons is not necessary at this time. (4) PDU construction was completed in December. The bulk of insulation work was completed at the end of November. Much effort has been put into pressure testing the PDU`s systems. The startup team has become adept at finding and correcting such leaks. (5) SOP writing for the PDU was completed this quarter with communication with the software programmer to insure agreement between the software and SOP.

    This quarterly technical progress report summarizes work completed during the Second Quarter of the Second Budget Period, July 1 through September 30, 1993, under the Department of Energy (DOE) Cooperative Agreement No. DE-FC21-90MC25140 entitled ``Hot Gas Cleanup Test Facility for Gasification and Pressurized Combustion.`` The objective of this project is to evaluate hot gas particle control technologies using coal-derived gas streams. This will entail the design, construction, installation, and use of a flexible test facility which can operate under realistic gasification and combustion conditions. The major particulate control device issues to be addressed include the integration of the particulate control devices into coal utilization systems, on-line cleaning techniques, chemical and thermal degradation of components, fatigue or structural failures, blinding, collection efficiency as a function of particle size, and scaleup of particulate control systems to commercial size. The conceptual design of the facility was extended to include a within scope, phased expansion of the existing Hot Gas Cleanup Test Facility Cooperative Agreement to also address systems integration issues of hot particulate removal in advanced coal-based power generation systems. This expansion included the consideration of the following modules at the test facility in addition to the existing Transport Reactor gas source and Hot Gas Cleanup Units: Carbonizer/Pressurized Circulating Fluidized Bed Gas Source. Hot Gas Cleanup Units to mate to all gas streams; Combustion Gas Turbine; and Fuel Cell and associated gas treatment. This expansion to the Hot Gas Cleanup Test Facility is herein referred to as the Power Systems Development Facility (PSDF). The major emphasis during this reporting period was continuing the detailed design of the facility.

    This first quarterly report documents technical progress during the period 31 December 1983 through 30 March 1984. The technical effort is 17 months in duration and is divided into two major technical tasks: Task VII, Hardware Fabrication and PDU Modifications, and Task VIII, Performance Testing. The design of test hardware and process development unit modifications had been previously completed as part of Task VI of the current contract. Task VII involves the fabrication of test hardware and modification of an existing 1-ton/h hydroliquefaction PDU at Rockwell's facilities for use as a hydrogasifier test facility. During this report period, fabrication of the test hardware and modifications to the PDU were initiated. Test hardware fabrication is now approximately 80% complete and should be completed by the end of May 1984. PDU modifications are progressing well and should be completed by the end of June 1984. The completed test hardware fabrication and PDU modifications will allow the conduct of short duration (1 to 2 h) hydrogasification tests along with preburner assembly performance evaluation tests in order to fulfill the test program objectives. Separate supplies of hydrogen, oxygen, methane, carbon monoxide, and water (for steam generation) are provided for this purpose. The modified facility is designed to accommodate both 10- and 20-ft-long hydrogasifier reactors so that residence times will be in the range of 2 to 6 s when coal is fed at a nominal 1/2 ton/h into reactors at 1000 psia pressure. Provisions are being made for real-time analysis of the product gases using an on-line gas chromatograph system. Test planning was the only Task VIII effort active during this report period. An initial (preliminary) test matrix has been defined. Preparation of a data analysis plan is underway, and data reduction programs are being programmed. 17 references, 25 figures, 6 tables.

    In the current quarterly technical progress report we present data and results on transient kinetic studies of the steam-char reaction system for activated coconut and lignite chars. These experiments were conducted in a fashion similar to the previous char-CO/sub 2/ studies, under approximately the same experimental conditions. The two principal product species, H/sub 2/ and CO, were monitored using the automatic mass programming system developed especially for this project. In order to perform the steam-char experiments, the original apparatus was modified by the addition of a steam generation/condensate removal system. The steam-char reaction system, being somewhat more complex than the CO/sub 2/-char reaction system, was modeled with a six-parameter, elementary kinetic scheme. The ''effective'' active site concentrations determined from the steam gasification data were of the same order of magnitude, and behaved in a similar fashion, to those obtained for the CO/sub 2/ gasification studies. The implications of this result are briefly discussed. 21 refs., 23 figs., 2 tabs.

    This is the eleventh Quarterly Technical Progress Report under DOE Contract DE-AC22-89PC89883. Major topics reported are: (1) The results of a study designed to determine the effects of the conditions employed at the Wilsonville slurry preheater vessel on coal conversion is described. (2) Stable carbon isotope ratios were determined and used to source the carbon of three product samples from Period 49 of UOP bench-scale coprocessing Run 37. The results from this coprocessing run agree with the general trends observed in other coprocessing runs that we have studied. (3) Microautoclave tests and chemical analyses were performed to ``calibrate`` the reactivity of the standard coal used for determining donor solvent quality of process oils in this contract. (4) Several aspects of Wilsonville Close-Coupled Integrated Two-Stage Liquefaction (CC-ITSL) resid conversion kinetics were investigated; results are presented. Error limits associated with calculations of deactivation rate constants previously reported for Runs 258 and 261 are revised and discussed. A new procedure is described that relates the conversions of 850{degrees}F{sup +} , 1050{degrees}F{sup +}, and 850 {times} 1050{degrees}F material. Resid conversions and kinetic constants previously reported for Run 260 were incorrect; corrected data and discussion are found in Appendix I of this report.

Major topics reported are: Fifty-eight process samples from HRI CTSL Bench Unit Run CC-15 (227-75) were analyzed to provide information on process performance. Run CC-15 was operated for 14 periods (days) from October 21 through November 3, 1992 in the thermal/catalytic configuration with Black Thunder Mine (Wyodak and Anderson seams) coal and Shell S-317 Ni/Mo supported extrudate catalyst. The run was made to test performance with and without a dispersed hydrous iron hydroxide catalyst precursor impregnated in the coal. Results are compared with those of previous HRI CTSL bench unit Run CC-1, which was operated in the catalytic/catalytic configuration, also with Shell S-317 catalyst. Several HRI Run CC-15 product distillate fractions prepared by the National Institute for Petroleum and Energy Research (NIPER) for petroleum inspection tests were further characterized by CONSOL. These characterization data are presented. MicroAutoclave tests and chemical analyses were performed to evaluate the solvent quality of two potential solvents for Alberta Research Council ARC. Eight product samples from catalytic dehydrogenation experiments were characterized for the University of Pittsburgh. A description is presented of the thermogravimetric analysis (TGA) method for determination of resid concentration/resid conversion, which was adapted for use in-house from HRI`s standard method.

    This is the tenth Quarterly Technical Progress Report under DOE Contract DE-AC22-89PC89883. Process oils from Wilsonville Run 262 were analyzed to provide information on process performance. Run 262 was operated from July 10 through September 30, 1991, in the thermal/catalytic Close-Coupled Integrated Two-Stage Liquefaction (CC-ITSL) configuration with ash recycle. The feed coal was Black Thunder Mine subbituminous coal. The high/low temperature sequence was used. Each reactor was operated at 50% of the available reactor volume. The interstage separator was in use throughout the run. The second-stage reactor was charged with aged Criterion 324 catalyst (Ni/Mo on 1/16 inch alumina extrudate support). Slurry catalysts and sulfiding agent were fed to the first-stage reactor. Molyvan L is an organometallic compound which contains 8.1% Mo, and is commercially available as an oil-soluble lubricant additive. It was used in Run 262 as a dispersed hydrogenation catalyst precursor, primarily to alleviate deposition problems which plagued past runs with Black Thunder coal. One test was made with little supported catalyst in the second stage. The role of phenolic groups in donor solvent properties was examined. In this study, four samples from direct liquefaction process oils were subjected to O-methylation of the phenolic groups, followed by chemical analysis and solvent quality testing.

    This report is the twenty-first Quarterly Technical Progress Report for US Department of Energy Cooperative Agreement No. DE-FC05-77ET10069 for EDS Coal Liquefaction Process Development Phase V. A detailed comparison of RCLU, CLPP, and ECLP yields has been initiated. This study builds off previous yield modeling results, which found that RCLU, CLPP, and ECLP yields were generally consistent given the scatter of the data, although some differences were noted. These pilot unit yield differences have now been quantified, and operating/configurational differences which account for some of them have been identified. Preliminary yield comparison results after correcting for these known process differences between the pilot plants indicate that: RCLU and CLPP yields are generally consistent; ECLP's conversion is about 5 lb/100 lb DAF coal lower than RCLU/CLPP at comparable operating conditions; and work has been initiated to define the EDS slurry preheater feed system design (based on slurry distributor manifold guidelines and coking correlation predictions, which influence furnace pass control issues such as slurry flow measurement). EDS hydrotreated naphtha showed a low level of systemic toxicity to rats exposed to the vapor six hours per day, five days per week for thirteen weeks.

These key highlights are: (1) Mixed LnCl{sub 3} solutions were successfully tested as substitutes for LaCl{sub 3} in preparing OHC catalysts. This will dramatically lower the price of the catalyst. (2) Six catalyst samples were received from UCI. Each was made via either incipient wetness or compounded extrudate techniques. Four of the catalysts have been screened. All seem adequate. (3) Contact has opened with Calsicat as an alternate catalyst supplier to UCI. It should be valuable to draw from their catalyst expertise. (4) It has been decided to tie into the plant`s natural gas source. Methods of cleaning up this stream are being investigated. (5) PDU construction completion is expected the first week in November. Pressure testing and punchout fix-up work remain to be completed. (6) Three new engineers were hired to work on the PDU. Half of the temporary operating procedures (TOP`s) have been written. SOP completion date is targeted for the beginning of November.

    It is the goal of this research to provide the technical basis for development of a process to remove chlorine from coal prior to combustion, based on a thermal treatment process. Under the reaction conditions employed, the behavior of other trace elements of concern will also be evaluated. The recovery of the chlorine removed from the coal as a marketable by-product, calcium chloride suitable for use as a road deicer, is also being investigated using a novel absorption/crystallization device. We have previously reported on equipment modifications required to attain the necessary data. A tube furnace system employs a flow of nitrogen across the coal sample to carry the HCl released to an absorber, where a chloride specific electrode measures the concentration of the chloride in solution. The data is analyzed by a least squares technique to provide values of the three kinetic constants in a modified first order rate equation used to model the system. During the past quarter, several runs were performed, and kinetic constants determined. After 20 minutes at 385{degree}C, 90% of the chlorine was removed from IBC-109 {minus}200 mesh coal. The data are encouraging, in terms of being able to provide a basis for design of a precombustion chlorine removal process based on thermal treatment.

    The Magnetohydrodynamics (MHD) Integrated Topping Cycle (ITC) Project represents the culmination of the proof-of-concept (POC) development stage in the US Department of Energy (DOE) program to advance MHD technology to early commercial development stage utility power applications. The project is a joint effort, combining the skills of three topping cycle component developers: TRW, Avco/TDS, and Westinghouse. TRW, the prime contractor and system integrator, is responsible for the 50 thermal megawatt (50 MW{sub t}) slagging coal combustion subsystem. Avco/TDS is responsible for the MHD channel subsystem (nozzle, channel, diffuser, and power conditioning circuits), and Westinghouse is responsible for the current consolidation subsystem. The ITC Project will advance the state-of-the-art in MHD power systems with the design, construction, and integrated testing of 50 MW{sub t} power train components which are prototypical of the equipment that will be used in an early commercial scale MHD utility retrofit. Long duration testing of the integrated power train at the Component Development and Integration Facility (CDIF) in Butte, Montana will be performed, so that by the early 1990`s, an engineering data base on the reliability, availability, maintainability and performance of the system will be available to allow scaleup of the prototypical designs to the next development level. This Sixteenth Quarterly Technical Progress Report covers the period May 1, 1991 to July 31, 1991.

    The main objectives of the project are to investigate the fundamental aspects of particle-liquid interaction in fine coal dewatering, to conduct laboratory and pilot plant studies on the applicability of hyperbaric filter systems and to develop process conditions for dewatering of fine clean coal to less than 20 percent moisture. The program consist of three phases, Model Development, Laboratory Studies, and Field Testing. The Pennsylvania State University is leading efforts in Phase 1, the University of Kentucky in Phase 2, and Consol Inc. in Phase 3 of the program. All three organizations are involved in all the three phases of the program. The Pennsylvania State University is developing a theoretical model for hyperbaric filtration systems, whereas the University of Kentucky is conducting experimental studies to investigate fundamental aspects of particle-liquid interaction and application of high pressure filter in fine coal dewatering. The optimum filtration conditions identified in phase 1 and 2 will be tested in a Consol Inc. coal preparation plant using an Andritz Ruthner portable hyperbaric filtration unit.

    The broad objective of this project is to obtain improved, quantitative understanding of the transient plasticity of bituminous coals under high heating rates and other reaction and pretreatment conditions of scientific and practical interest. To these ends the research plan is to measure the softening and resolidification behavior of two US bituminous coals with a rapid-heating, fast response, high-temperature coal plastometer, previously developed in this laboratory. Specific measurements planned for the project include determinations of apparent viscosity, softening temperature, plastic period, and resolidificationtime for molten coal: (1) as a function of independent variations in coal type, heating rate, final temperature, gaseous atmosphere (inert, 0{sub 2} or H{sub 2}), and shear rate; and (2) in exploratory runs where coal is pretreated (preoxidation, pyridine extraction, metaplast cracking agents), before heating. The intra-coal inventory and molecular weight distribution of pyridine extractables will also be measured using a rapid quenching, electrical screen heater coal pyrolysis reactor. The yield of extractables is representative of the intra-coal inventory of plasticing agent (metaplast) remaining after quenching. Coal plasticity kinetics will then be mathematically modeled from metaplast generation and depletion rates, via a correlation between the viscosity of a suspension and the concentration of deformable medium (here metaplast) in that suspension. Work during this reporting period has been concerned with re-commissioning the rapid heating rate plastometer apparatus.

The forecast period for this issue of the Outlook extends from the first quarter of 1996 through the fourth quarter of 1997. Values for the fourth quarter of 1995, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data).

Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service. The cases are produced using the Short-Term Integrated Forecasting System (STIFS). The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook.

    In the third quarterly report, adsorption of heavy metals ions such as Cu(II) and Cr(VI) onto soils drawn from the laboratory-type wetland (LW) was shown to be weak. On the other hand, it was shown that modified-clays did adsorb Cr(VI) ions strongly at pH 4.5. Further, studies on the pH dependence of the adsorption of {beta}-naphthoic acid, (NA), a well-documented contaminant in many oil and gas well waste waters (4), onto modified-clays were undertaken and it was shown that uptake of NA by modified-clays was of the high affinity type at pH 4.5 and 7.0, but weak at pH 9.0. Adsorption of heavy metal ions, Cu{sup 2+}, and CR(VI) onto algae, a proposed wetland amendment, was carried out and the results were presented and discussed in the fourth quarterly report. Studies on the dynamics of uptake of phenol and NA by laboratory-type wetlands (LWs) were initiated and preliminary results indicated that both phenol and NA were sorbed onto components of LWs. A mass balance model has been developed to quantify the fate of phenol in LWs. The model is based on the postulate that the fate of phenol in LWs can be attributed to a combination of (1) evaporation of solute and solvent, (2) adsorption of phenol onto various components of LW and (3) its biodegradation, both in solution and at solid-liquid interface. As an initial approximation, the latter two processes have been lumped together and incorporated into the model as an unit operation. Both zero order and first order kinetics for the disappearance of phenol have been considered. Evaporative losses of water and phenol have also been taken into account and this model is presented and discussed in this quarterly report.

    The objective of this research is to show whether or not pulsed excimer laser annealing (PELA) of ion-implanted junctions is a cost effective replacement for diffused junctions in fabricating crystalline silicon solar cells. The preliminary economic analysis completed during the first quarter of this program shows that the use of PELA to fabricate both the front junction and back surface field (BSF) would cost approximately 35 cents per peak watt (Wp), compared to a cost of 15 cents/Wp for diffusion, aluminum BSF and an extra cleaning step in the baseline process described by JPL. The cost advantage of the PELA process depends on improving the average cell efficiency from 14% to 16%, which would lower the overall cost of the module by about 15 cents/Wp. The technical goal of this research is to develop an optimized PELA process compatible with commercial production, and to demonstrate increased cell efficiency with sufficient product for adequate statistical analysis. During the first quarter of this program an excimer laser annealing station was set-up and made operational. The first experiment used 248 nm radiation to anneal phosphorus implants in polished and texture-etched silicon. Preliminary results showed that the PELA processed cells had overall efficiencies comparable to furnace annealed ion implanted controls, and that texture-etched material requires lower fluence for annealing than polished silicon. Process optimization will be carried out in the second quarter.

    Research in this project centers upon developing a new approach to the direct liquefaction of coal to produce an all-distillate product slate at a sizable cost reduction over current technology. The approach integrates all aspects of the coal liquefaction process including coal selection, pretreatment, coal swelling with catalyst impregnation, coal liquefaction experimentation, product recovery with characterization, alternate bottoms processing, and a technical assessment including an economic evaluation. The project is being carried out under contract to the United States Department of Energy. On May 28, 1992, the Department of Energy authorized starting the experimental aspects of this projects; therefore, experimentation at Amoco started late in this quarterly report period. Research contracts with Auburn University, Pennsylvania State University, and Foster Wheeler Development Corporation were signed during June, 1992, so their work was just getting underway. Their work will be summarized in future quarterly reports. A set of coal samples were sent to Hazen Research for beneficiation. The samples were received and have been analyzed. The literature search covering coal swelling has been up-dated, and preliminary coal swelling experiments were carried out. Further swelling experimentation is underway. An up-date of the literature on the liquefaction of coal using dispersed catalysts is nearing completion; it will be included in the next quarterly report.

    To reduce their sulfur emissions, many coal-fired electric power plants use wet flue-gas scrubbers. These scrubbers convert sulfur oxides into solid sulfate and sulfite sludge, which must then be disposed of. This sludge is a result of reacting limestone with sulfur dioxide to precipitate calcium sulfite and calcium sulfate. It consists of calcium sulfite (CaSO{sub 3}{circ}0.5H{sub 2}O), gypsum (CaSO{sub 4}{circ}2H{sub 2}O), and unreacted limestone (CaCO{sub 3}) or lime (Ca(OH)2), with miscellaneous objectionable impurities such as iron oxides, silicates, and magnesium, sodium, and potassium oxides or salts. These impurities prevent many sludges from being utilized as a replacement for natural gypsum, and as a result they must be disposed of in landfills, which presents a serious disposal problem. Knowledge of scrubber sludge characteristics is necessary for the development of purification technologies which will make it possible to directly utilize scrubber sludges rather than landfilling them. This project is studying the use of minimal-reagent froth flotation as the purification process, using the surface properties of the particles of unreacted limestone to remove them and their associated impurities from the material, leaving a purified calcium sulfite/gypsum product.

    On September 30, 1993, the U.S. Department of Energy-Morgantown Energy Technology Center and Southern Illinois University at Carbondale (SIUC) entered into a cooperative research agreement entitled {open_quotes}Management of Dry Flue Gas Desulfurization By-Products in Underground Mines{close_quotes} (DE-FC21-93MC30252). Under the agreement Southern Illinois University at Carbondale will develop and demonstrate several technologies for the placement of coal combustion residues in abandoned coal mines, and will assess the environmental impact of such underground residues placement. Previous quarterly Technical Progress Reports have set forth the specific objectives of the program, and a discussion of these is not repeated here. Rather, this report discusses the technical progress made during the period April 1 - June 30, 1995. A final topical report on the SEEC, Inc. demonstration of its technology for the transporting of coal combustion residues was completed during the quarter, although final printing of the report was accomplished early in July, 1995. The SEEC technology involves the use of Collapsible Intermodal Containers (CIC`s) developed by SEEC, and the transportation of such containers - filled with fly ash or other coal combustion residues - on rail coal cars or other transportation means. Copies of the final topical report, entitled {open_quotes}The Development and Testing of Collapsible Intermodal Containers for the Handling and Transport of Coal Combustion Residues{close_quotes} were furnished to the Morgantown Energy Technology Center. The Rapid Aging Test colums were placed in operation during the quarter. This test is to determine the long-term reaction of both the pneumatic and hydraulic mixtures to brine as a leaching material, and simulates the conditions that will be encountered in the actual underground placement of the coal combustion residues mixtures. The tests will continue for about one year.

    The principle of operation of the magnetic-particle, mass-flow measuring device was described in the first quarterly report. In addition, the results of a few preliminary tests which were carried out to show the feasibility of using this device were described in the third quarterly report. It was noted that the output signal from the device is proportional to velocity and that saturation of the material in the vicinity of the read coil had not yet been achieved. Thus, efforts during this quarter were concentrated upon two objectives - achieving saturation of the magnetic material in the vicinity of the road coil and establishing calibration procedures to be used with the device installed in a fluidized bed.

    In work related to the design and construction of the Process Development Unit (PDU) this quarter involved further detail design and a real start to the construction activities. Status updates are given below for each discipline in the Task 2.0 and 3.0 headings. This work is progressing well. with the caveat of several small slips in the scheduling. On the catalyst development front this quarter was extremely productive. Many catalyst screening experiments were completed and they showed that control of the reaction exotherm is going to be quite challenging under PDU conditions. The presence of much more efficient reactor design and the ability to maintain closer to isothermal conditions is expected to give a significant advantage in actual PDU operation. A major concern at the moment is the cost of La in the catalyst being used. An action plan to remedy this is being put together.

    The FETC/EPRI Biomass Cofiring Program has accelerated the pace of cofiring development by increasing the testing activities plus the support activities for interpreting test results. Past tests conducted and analyzed include the Allen Fossil Plant and Seward Generating Station programs. On-going tests include the Colbert Fossil Plant precommercial test program, the Greenidge Station commercialization program, and the Blount St. Station switchgrass program. Tests in the formative stages included the NIPSCO cofiring test at Michigan City Generating Station. Analytical activities included modeling and related support functions required to analyze the cofiring test results, and to place those results into context. Among these activities is the fuel availability study in the Pittsburgh, PA area. This study, conducted for Duquesne Light, supports their initial investigation into reburn technology using wood waste as a fuel. This Quarterly Report, covering the third quarter of the FETC/EPRI Biomass Cofiring Program, highlights the progress made on the 16 projects funded under this cooperative agreement.

    During the first quarter of 1994, we continued work on Tasks 2, 3, 4, 5, and 6. We also began work on Task 7. In Task 2, we incorporated 4.5% O{sub 2} into our simulated flue gas stream during this quarter`s NO{sub x}-absorption experiments. We also ran experiments using Cobalt (II)-phthalocyanine as an absorbing agent We observed higher absorption capacities when using this solution with the simulated flue gas containing O{sub 2}. In Task 3, we synthesized a few EDTA polymer analogs. We also began scaled up synthesis of Co(II)-phthalocyanine for use in Task 5. In Task 4, we performed experiments for measuring distribution coefficients (m{sub i}) Of SO{sub 2} between aqueous and organic phases. This was done using the liquor regenerating apparatus described in Task 6. In Task 5, we began working with Co(II)-phthalocyanine in the 301 fiber hollow fiber contactor. We also calculated mass transfer coefficients (K{sub olm}) for these runs, and we observed that the gas side resistance dominates mass transfer. In Task 6, in the liquor regeneration apparatus, we observed 90% recovery of SO{sub 2} by DMA from water used as the scrubbing solution. We also calculated the distribution of coefficients (m{sub i}). In Task 7, we established and began implementing a methodology for completing this task.

    Work this quarter included equipment installation, shakedown testing, and the beginning of the detailed testing program. With the exception of ongoing Task 4: Sample Characterization, Tasks 1 through 8 are now complete. Task 10: Detailed Testing and Task 12: Sample Analysis began this quarter and will consume all available time during the 5th quarter. Installation and testing of the process equipment, mechanical systems, as well as the electrical systems were completed. The shakedown process uncovered several necessary modifications to the circuit which were subsequently completed. Most of the changes concerned piping and valving modifications which allowed for better material flow and sampling. The circuit was operated with coal to determine the time for each unit to reach steady state. The primary objective of the proposed work is to design, install, and operate an advanced fine coal processing circuit combining the Microcel{trademark} and Multi-Gravity-Separator (MGS) technologies. Both of these processes have specific advantages as stand-alone units. For example, the Microcel column effectively removes ash-bearing mineral matter, while the MGS efficiently removes coal-pyrite composites.

    This report describes second quarter activities for a project aimed at demonstrating the technical feasibility of advanced high efficiency concentrator solar converters. The goal of the program is to achieve 30% conversion efficiency with a converter operating at 30/sup 0/C under 500 to 1000 SUN AM2 illumination and 25% conversion efficiency with a converter operating at 150/sup 0/C under 500 to 1000 SUN AM2 illumination. The approach is to fabricate two cell, non-lattice matched, monolithic stacked converters using optimum pairs of cells having bandgaps in the range of 1.6 to 1.7 eV and 0.95 to 1.1 eV. The high bandgap cells are to be fabricated using MOCVD or LPE to produce the needed AlGaAs layers of optimized composition, thickness and doping to produce high performance, heteroface homojunction devices. The low bandgap cells are to be similarly fabricated from AlGaSb(As) compositions by LPE. These subcells are then to be joined into a monolithic structure by an appropriate thermal bonding technique which will also form the needed transparent intercell ohmic contact (IOC) between the two subcells. The activities this quarter have been largely focused on the development and study of low bandgap cell structures and attempts to develop suitable techniques for the thermal bonding operation.

    In the last Quarterly Technical Progress Report the authors reported the synthesis and (partial characterization) and SCR (Selective Catalytic Reduction of NO) activity for a delaminated Fe{sub 2}O{sub 3}-pillared clay (Fe{sub 2}O{sub 3}-PILC). The SCR activity for this PILC was substantially higher than that of the commercial-type V{sub 2}O{sub 5} + WO{sub 3}/TiO{sub 2} catalyst. During the past quarter, the authors first completed the characterization of the delaminated Fe{sub 2}O{sub 3}-PILC catalyst. Both physical characterization (micropore probing by adsorption and Moessbauer spectroscopy) and chemical characterization (by IR spectroscopy) were performed. Since the synthesis of this PILC sample was undertaken under a specific set of conditions and it is known that the PILC properties depend strongly on the synthesis conditions, they then proceeded to examine in a systematic manner the dependence of the catalytic properties of the PILC on its synthesis conditions. Four parameters in the synthesis were studied: Fe precursors, pH of the pillaring solution, concentration of the pillaring solution, and the starting clay. Finally, the effect of the Cr{sub 2}O{sub 3} promoter on the SCR activity of the pillar clay was studied. Results are reported.

    This project is a major step in the Department of Energy`s program to show that ultra-clean coal-water slurry fuel (CWF) can be produced from selected coals and that this premium fuel will be a cost-effective replacement for oil and natural gas now fueling some of the industrial and utility boilers in the United States. The replacement of oil and gas with CWF can only be realized if retrofit costs are kept to a minimum and retrofit boiler emissions meet national goals for clean air. These concerns establish the specifications for maximum ash and sulfur levels and combustion properties of the CWF. This cost-share contract is a 48-month program which started on September 30, 1992. This report discusses the technical progress made during the 4th quarter of the project from July 1 to September 30, 1993.

    IGT has developed a microbial culture of Rhodococcus rhodochrous, designated as IGTS8, that is capable of specifically cleaving carbon-sulfur bonds in a range of organosulfur model compounds and is capable of removing organic sulfur from coal and petroleum without significantly sacrificing the calorific value of the fuel. Although IGTS8 possesses the ability to specifically remove organic sulfur from coal, a major research need is to develop improved strains of microorganisms that possess higher levels of desulfurization activity and therefore will permit more favorable biodesulfurization process conditions: faster rates, more complete removal, and smaller reactor size. strain improvement is the single most important aspect to the development of a practical coal biodesulfurization process and accordingly is the focus of research in this project. During this quarter the promoter probe vectors that were constructed last quarter were found to be unstable in E. coli. Fragments of R. rhodochrous IGTS8 chromosomal DNA were cloned into pRCAT3 and pRCM1 (previously described in final ICCI report 1993). Many derivatives of pRCM1 and pRCAT3 receiving inserts that regulated the expression of chloramphenicol resistance in Rhodococcus rhodochrous IGTS8 proved to be unstable in E. coli frequently yielding plasmids containing deletions. Stable inserts have been observed ranging from 100 bp to 2.0 kb that regulated expression in Rhodococcus rhodochrous IGTS8. Subtractive hybridization studies continue, several candidates have been isolated and are being confirmed for inducible promoters. Primer extension analysis of the Rhodococcus rhodochrous IGTS8 16S RNA promoter region was initiated this quarter.

    Previous work in this laboratory on cuprous oxide Schottky barrier photovoltaic cells showed that some potential improvements were limited by chemical degradations at the junction (1), e.g., in Al/Cu/sub 2/O cells, the aluminum reduced the surface of the Cu/sub 2/O to metallic Cu. The present project is being devoted to a study of methods to avoid this problem and also to the development of other methods of improving the efficiency of Cu/sub 2/O cells. The first quarterly report was devoted to a study of thin oxide interlayers between the metal and the Cu/sub 2/O which gives MIS structures. The most stable interlayers were obtained with SiO/sub 2/. The second quarterly report covered some initial work on heterojunctions with other oxides on Cu/sub 2/O. The most stable heterojunctions were obtained with CdO on Cu/sub 2/O. The present report presents some results on Auger studies of the oxide heterojunctions, the preparation of doped Cu/sub 2/O by introduction of impurities in the starting copper, the exploration of several method for the study of diffusion length, and some initial attempts on the laser annealing of Cu/sub 2/O.

    This report describes work completed during the fifth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. Work this quarter focused on analytical characterization of untreated and treated Wyodak subbituminous coal and Illinois {number_sign}6 bituminous coal. Mossbauer spectroscopy and x-ray diffraction techniques were used to study the effect of methanol/HCl pretreatment on the composition of each coal`s inorganic phase. Results from these studies indicated that calcite is largely removed during pretreatment, but that other mineral species such as pyrite are unaffected. This finding is significant, since calcite removal appears to directly correlate with low severity liquefaction enhancement. Further work will be performed to study this phenomenon in more detail.

    Examination of the photochemical extractions of the four Argonne Premium Coal Residues has been under way in a routine manner during this last quarter. An unexpectedly great effort last quarter had been necessary to find extraction solvents and photochemical reagents that were photochemically stable and inert. While it is a rather poor thermal extraction solvent, acetonitrile has proven to be the best solvent the authors have examined. In addition to runs with only the acetonitrile solvent present, experiments were performed with the photochemical reagents, benzophenone and pyridine. Both ketone and pyridine triplet states are well-known for their hydrogen abstraction and electron transfer capabilities. The photochemical reagents were used at concentrations resulting in 50% transmission of the light across the reactor pathlength at 320 nm. Experiments with the quartz cutoff filter remain to be completed at concentrations resulting in 50% transmittance at lower wavelengths. Changes in the transmission of light by the column effluent were monitored continuously and the extraction yield by weight was measured by evaporation of the solvent and subtraction of reagent weight. Thermal extraction yields without light under otherwise identical conditions were measured for comparison. As a check on undesirable effects, such as solvent photochemical degradation, otherwise identical light and dark experiments were also done without the coal on the column.

    The Energy Information Administration (EIA) prepares quarterly short-term energy supply, demand, and price projections for publication in January, April, July, and October in the Outlook. The forecast period for this issue of the Outlook extends from the second quarter of 1997 through the fourth quarter of 1998. Values for the first quarter of 1997, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the second quarter 1997 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook. By varying the assumptions, alternative cases are produced by using the Short-Term Integrated Forecasting System (STIFS). 34 figs., 19 tabs.

    This is the eighth in a series of quarterly reports describing the activities performed under Contract No. DE-AC21-94MC31160. Analyses of Hot Gas Stream Cleanup (HGCU) ashes and descriptions of filter performance address aspects of filter operation that are apparently linked to the characteristics of the collected ash or the performance of the ceramic barrier filter elements. Task 1 is designed to generate a data base of the key characteristics of ashes collected from operating advanced particle filters (APFS) and to relate these ash properties to the operation and performance of these filters. Task 2 concerns testing and failure analysis of ceramic filter elements. Under Task I during the past quarter, additional analyses were performed on ashes from the Ahlstrom 10 MWt Pressurized Fluidized Circulating Fluid Bed (PCFB) facility located at Karhula, Finland. Work continued on the HGCU data base being constructed in Microsoft Access. A variety of information has been entered into the data base, including numerical values, short or long text entries, and photographs. Detailed design of a bench top device for high temperature measurement of ash permeability has also begun. In addition to these activities, a paper was prepared and a poster was presented summarizing recent work performed under this contract at the 1996 DOE/METC Contractor`s Conference. A presentation was also given corresponding to the manuscript entitled Particle Characteristics and High-Temperature Filtration that was prepared for publication in the Proceedings of the Thirteenth Annual International Pittsburgh Coal Conference held this September in Pittsburgh, PA. Arrangements have been made to be present at the DOE/METC Modular Gas Cleanup Rig (MGCR) at the conclusion of the next run of the DOE/METC air blown Fluid Bed Gasifier (FBG).

    Our objective for this quarter was to study the effect of co-feeding a 1-olefin on the Ruhrchemie catalyst activity and selectivity, during-both conventional Fisher-Tropsch synthesis (FTS) and FTS under supercritical conditions. We used propane as the supercritical fluid and 1-dodecene (1-C{sub 12}H{sub 24}) in this test. Motivation for this study was the work of Fujimoto and co-workers who reported that suppression of methane and enhancement of high molecular weight hydrocarbons selectivities occurs with co-feeding of 1-olefins (1-heptene, 1-tetradecene, or 1-hexadecene) during FTS under supercritical conditions, but not during the conventional FTS (Co-La catalyst supported on silica in supercritical n-pentane).The diffusion coefficients of products in supercritical fluids is discussed.

    The aim of this project is to use the techniques of molecular genetics to identify, clone, sequence, and enhance the expression of proteins which remove sulfur covalently bound to coal. This includes the movement and expression of these proteins into bacterial species which may be more useful in the industrial application of a biological desulfurization process. This quarter we finalized the initial cloning and sequencing of the dibenzothiophene (DBT) metabolic (``dox``) genes from strain C18. In addition, we constructed several mutations in single dox genes and have begun to dissect the contribution of each gene product in the DBT degradation pathway. Using a probe derived from DNA adjacent to a transposon which inactivated DBT metabolism, the DBT active genes from A15 have been cloned and identified on cosmids. We have also electroporated Thiobacillus ferrooxidans with a plasmid containing a chloramphenicol resistant transposon. Colonies of T. ferrooxidans resistant to chloramphenicol were obtained.

    This quarterly report describes results from the experimental studies on oxidative coupling of methane, oxygen conducting perovskite dense membrane synthesis and modeling studies of the methane coupling reaction. The focus of the experimental study is to explore the effects of varying catalyst loading, varying methane to oxygen ratios and feed conditions when the oxygen conversion is much less than 100%. Results from these studies help in understanding the effects of various parameters controlling methane coupling. Dense membrane synthesis and characterization results are presented which describe new approaches to the synthesis and characterization of these membranes. The modeling results described in this report present a theoretical fit to the experimental data on oxidative coupling of methane in fixed bed reactors. The parameters from the fit are used to predict the trends in experimental data obtained from VYCOR membrane reactors. The predicted trends are based on a theoretical model employing simplified methane coupling kinetics.

    A multistep direct liquefaction process specifically aimed at low-rank coals (LRCs) has been developed at the Energy & Environmental Research Center (EERC). The process consists of a preconversion treatment to prepare the coal for solubilization, solubilization of the coal in the solvent, and polishing using a phenolic solvent or solvent blend to complete solubilization of the remaining material. The product of these three steps can then be upgraded during a traditional hydrogenation step. This project addresses two research questions necessary for the further development and scaleup of this process: (1) determination of the recyclability of the solvent used during solubilization and (2) determination of the minimum severity required for effective hydrotreatment of the liquid product. The project involves two tasks, the first consisting of ten recycle tests and the second consisting of twelve hydrotreatment tests performed at various conditions. Activities performed during this quarter are discussed.

    The overall objective of the contract is to improve understanding of the fundamental chemistry of coprocessing. A primary objective is to evaluate methods to distinguish between compound classes originating from coal versus those originating from petroleum resid while a corollary objective is to provide detailed knowledge on the composition of coprocessing products. This and the prior quarterly report summarize work conducted in support of the latter objective in which process development unit samples produced by HRI, Inc. were subjected to detailed analysis. Coprocessing resid samples selected for detailed analysis were made under constant conditions except for variations in coal concentration or in the coal (New Mexico subbituminous or Texas lignite). Separation of the resids into acid, base, saturate, and neutral-aromatic subtractions, separation of the neutral-aromatics by ring number and high temperature gas chromatography were discussed in the previous quarterly. This report includes results of nonaqueous titrations, elemental analyses and infrared spectroscopy. The hydrocarbon skeletons of saturated hydrocarbons in the coprocessing resids appear to be fundamentally different than those of aromatic species. Neutral-aromatic fractions contain minor levels of sulfur compounds, an unknown proportion of ether or other oxygen-containing species, and major concentrations of aromatic hydrocarbons containing from 3 to 7 aromatic rings. Base fractions contain predominantly single nitrogen compounds of azaarene or aminoaromatic type. Aminoaromatics (compounds analogous to aniline) are present in significant amounts in products made from New Mexico subbituminous coal but are nearly absent in the Texas lignite product. Acid fractions contain appreciable quantities of pyrrolic benzologs, but surprisingly low concentrations of compounds with a free OH group.

    The analyses of Hot Gas Stream Cleanup (HGCU) ashes and descriptions of filter performance studied under this contract are designed to address problems with filter operation that are apparently linked to characteristics of the collected ash. Task 1 is designed to generate a data base of the key characteristics of ashes collected from operating advanced particle filters (APFs) and to relate these ash properties to the operation and performance of these filters and their components. APF operations have also been limited by the strength and durability of the ceramic materials that have served as barrier filters for the capture of entrained HGCU ashes. Task 2 concerns testing and failure analyses of ceramic filter elements currently used in operating APFs and the characterization and evaluation of new ceramic materials. Task 1 research activities during the past quarter included characterizations of samples collected during a site visit on January 20 to the Department of Energy/Southern Company Services Power Systems Development Facility (PSDF). Comparisons were made between laboratory analyses of these PSDF ashes and field data obtained from facility operation. In addition, selected laboratory techniques were reviewed to assess their reproducibility and the influence of non-ideal effects and differences between laboratory and filter conditions on the quantities measured. Further work on the HGCU data base is planned for the next quarter. Two Dupont PRD-66 candle filters, one McDermott candle filter, one Blasch candle filter, and one Specific Surfaces candle filter were received at SRI for testing. A test plan and cutting plan for these candles was developed. Acquisition of two of the Dupont PRD-66 candle filters will allow candle-to-candle variability to be examined.

    Clean coal technologies that involve limestone for in situ sulfur capture generate lime/limestone products laden with sulfur at various oxidation states. If sulfur is completely stabilized as sulfate, the spent sorbent is ready for commercial utilization as gypsum. However, the presence of reduced sulfur species requires additional processing. Thermal oxidation of reduced sulfur frequently results in undesirable release of SO{sub 2}. Microbial oxidation might provide an inexpensive and effective alternative. Sorbents laden with reduced forms of sulfur such as sulfide or sulfite can serve as growth substrates for sulfur-oxidizing bacteria, which convert all sulfur to sulfate. The goals of this project are the following: (1) to optimize conditions for sulfate generation from sulfide, thiosulfate, and sulfite; (2) to test and optimize the effectiveness of microbial processing on spent sorbents from flue gas desulfurization, coal gasification, and fluidized bed combustion; (3) to search for hyperalkalinophilic thiobacilli, which would be effective up to pH 11. This quarter, temperature, nitrogen, and phosphate requirements for sulfate generation on thiosulfate were optimized with respect to two named strains and two promising isolates. Spent sorbents from three different power plants were tested for sulfite and thiosulfate contents, in preparation for bioprocessing.

    A number of promising techniques for improving the overall yield and economics of the tribromosilane based process to produce solar cell grade silicon is investigated. The current work is aimed at the identification of an optimum process and the characterization of that process through mini-plant operation and analysis. The three project tasks include process improvement studies, kinetic studies, and process economic studies. During this second quarter reporting period process improvement studies continued in the mini-plant, focusing on the correlation of current mini-plant yield results with prior laboratory scale work. Silicon bromination in the synthesis unit and tribromosilane purification in the distillation unit proceeded efficiently and without complication during this reporting period. Tribromosilane yields in the synthesis unit were low due to unobtainable higher reaction temperatures. Initial polycrystalline silicon production studies have indicated consistent yields of 85%. The laboratory scale static bulb reactor system was calibrated by observing the decomposition of t-butyl chloride. These results compared very well to results obtained by previous investigators for the same decomposition. Upon the conclusion of the calibration tests, the tribromosilane decomposition rate study was initiated. Two decompositions were completed and it was concluded that the reaction order can not be determined at this time. A free space reactor apparatus was assembled and tribromosilane decompositions, as a function of dilution in argon, was studied.

    Oxidation reactions are accomplished in an isothermal, high-pressure, flow reactor designed specifically for operation at supercritical water conditions. The reactor feed stream is prepared by mixing two separate streams. One stream is an aqueous solution of the phenolic reactant and the second stream is water with dissolved oxygen. Controlling the flow rates of these two streams allows us to control the reactor residence time and the relative amounts of the phenol and oxygen fed to the reactor. The reactor effluent is cooled and depressorized and then collected for analysis. The gaseous products are analyzed by gas chromatography (GC). The liquid-phase products are analyzed by GC, high-performance liquid chromatography, and GC-mass spectrometry. Our work to date has focused on the oxidation of cresols in SCW. We have explored the effects of temperature, pressure, and the concentrations of o-cresol, oxygen, and water. Table I gives these experimental conditions and the resulting ocresol conversions. We reported a portion of this data in our previous quarterly report. New information is given in the last three columns where we report the molar yields of phenol, CO{sub 2}, and CO. Molar yields were calculated as the molar flow rate of a given product divided by the initial molar flow rate of o-cresol and normalized by the stoichiometric coefficient. Earlier, we used the o-cresol conversion data to determine the parameters in a global reaction rate law for o-cresol disappearance.

    The University of Tennessee Space Institute (UTSI) reports on significant activity, task status, planned research, testing, development, and conclusions for the Magnetohydrodynamics (MHD) Coal-Fired Flow Facility (CFFF) and the Research and Development Laboratory. Although slowed by incessant rain during several days, work on the CFFF Bid Packages progressed to nearly 100 percent completion, excluding later punchlist items. On the quench system, the cyclone separator was delivered to UTSI, and under Downstream Components, the secondary combustor was received and the radiant slagging furnace was emplaced at the CFFF. Water quality analysis of Woods Reservoir provided the expected favorable results, quite similar to last year's. Generator experiments describing local current distribution are reported along with behavior under conditions of imposed leakage. Also, during the Quarter, the shelter for the cold flow modeling facility was constructed and circuits installation begun. A jet turbine combustor was tested for use as a vitiation burner. Samples taken from the exhaust duct, besides other applications, show that the refractories used are performing well in alleviating heat loss while exhibiting acceptable degredation. A new resistive power take-off network was designed and implemented.

    IGT has developed a microbial culture of Rhodococcus rhodochrous, IGTS8, that is capable of specifically cleaving carbon-sulfur bonds in a range of organosulfur model compounds and is capable of removing organic sulfur from coal and petroleum. Although IGTS8 possesses the ability to specifically remove organic sulfur from coal, a major research need is to develop improved strain`s of microorganisms that possess higher levels of desulfurization activity and therefore wall permit more favorable biodesulfurization process conditions: faster rates, mare complete removal, and smaller reactor size. Strain improvement is the single most important aspect to the development of a practical coal biodesulfurization process and accordingly is the focus of research in this project. Several possible strong promoters have been isolated and are in the process of being analyzed. When these promoters have been characterized for inducibility, strength, transcriptional start sites and other physical properties, they will be placed in front of the desulfurization genes and expression will be monitored. Improved promoter probe vectors have been constructed, allowing a conclusive screen of all putative Rhodococcus promoters. With the improved methodologies in the handling of Rhodococcus RNA, we have begun to gauge promoter expression using Northern blots. During this quarter we have constructed and successfully used a promoter probe vector using the {beta}-galactosidane gene from E. coli. A chromosomal promoter library was constructed upstream from the {beta}-galactosidase gene. Over 200 colonies were isolated that yielded {beta}-galactosidase activity.

    The purpose of this contract is to develop a process for converting light alkane gases to methyl chloride via oxyhydrochlorination using highly selective, stable catalysts in fixed-bed reactors designed to remove the large amount of heat generated, so as to control the reaction temperature. Further, the objective is to obtain the engineering data base necessary for developing a commercially feasible process and to evaluate the economics of the process. Significant progress was made in catalyst and PDU development this quarter. The key points of these developments are: Initial discussions have taken place with a catalyst supplier. United Catalysts, Inc. UCI came up with some good catalyst development suggestions and has agreed to produce a batch of catalyst for the PDU; previous plans for supply of methane for the PDU have fallen through. New options. including getting gas from Carrollton Utilities, are being evaluated; and PDU equipment installation is completed. and piping is 40% complete. The electrical work is close to being finished, and the instrumentation is underway.

    This report covers progress made in the first yearly quarter of a two year investigation using novel, very high frequency electron paramagnetic resonance (VHF EPR) spectroscopy techniques and instrumentation (one of only two W-band spectrometers in existence) developed earlier by these authors, to conduct further qualitative and quantitative studies of heteroatomic organic molecules in coal with particular emphasis on sulfur. Previous W-band (96 GHz) work is being extended to studies of new model compounds as well as coal and desulfurized coal samples. Typically, the model compounds under investigation and their analogues are found in coals as stable free radicals which give rise to an EPR signal. The preparation of radicals from compounds having widely varying structures and physical properties in a stable environment has long been a very difficult task. To address this problem, the refinement of several new and very useful methods of preparing of these stable free radicals in various glasses, at catalytic surfaces, and in solution, are presented in this first report. Free radical generation was accomplished by both UV photolysis as well as chemical oxidation/reduction techniques. By these methods, over 25 new compounds, often commercially derived from coal extracts, have been prepared and studied by conventional X-band EPR (9 GHz). Several representative W-band spectra are also presented.

    This report presents the work done on " Investigation of Syngas Interaction in Alcohol Synthesis Catalysts" during the last quarter. The major activity during this period is on FTIR absorption studies of Co/Cr catalysts using CO as a probe molecule. Transition metals cobalt and copper play significant roles in the conversion of syngas (CO + H2 ) to liquid fuels. With a view to examine the nature of interaction between CO and metal, the FTIR spectra of CO adsorbed on Co-Cr2 O3 composites were investigated. The results indicate that as cobalt loading increases, the intensity of the CO adsorption bands increase and several vibrational modes seem to be promoted. Heat treatment of the sample revealed two distinct processes of adsorption. Bands due to physisorption disappeared while bands due to chemisorption not only increased in intensity but persisted even after desorption. It seems that the physisorption process is more active when the catalyst is fresh and is hindered when carbidic/carbonyl formations occur on the metal surfaces.

    Global Basins Research Network will perform a field demonstration of their ``Dynamic Enhanced Recovery Technology`` to test the concept that the growth faults in EI-330 field are conduits through which producing reservoirs are charged and that enhanced production can be developed by producing directly from the fault zone. The site, operated by Penzoil, is located in 250 feet of water the productive depth intervals include 4000 to 9000 feet. Previous work, which incorporated pressure, temperature, fluid flow, heat flow, seismic, production, and well log data, indicated active fluid flow along fault zones. The field demonstration will be accomplished by drilling and production test of growth fault systems associated with the EI-330 field. The project utilizes advanced 3-D seismic analysis, geochemical studies, structural and stratigraphic reservoir characterization, reservoir simulation, and compact visualization systems. The quarterly progress reports contains accomplishments to date for the following tasks: Management start-up; database management; field and demonstration equipment; reservoir characterization, modeling; geochemistry; and data integration.

    Novel chemicals that can be used for increasing the efficiency of fine coal dewatering was developed at Virginia Tech. During the past quarter, Reagent A was tested on three different coal samples in laboratory vacuum filtration tests. These included flotation products from Middle Fork plant, Elkview Mining Company, and CONSOL, Inc. The tests conducted with the Middle Fork coal sample (100 mesh x 0) showed that cake moisture can be reduced by more than 10% beyond what can be achieved without using dewatering aid. This improvement was achieved at 1 lb/ton of Reagent A and 0.1 inch cake thickness. At 0.5 inches of cake thickness, the improvement was limited to 8% at the same reagent dosage. The results obtained with the Elkview coal (28 mesh x 0) showed similar advantages in using the novel dewatering aid. Depending on the reagent dosage, cake thickness, drying cycle time and temperature, it was possible to reduce the cake moisture to 12 to 14% rage. In addition to achieving lower cake moisture, the use of Reagent A substantially decreased the cake formation time, indicating that the reagent improves the kinetics of dewatering. The test results obtained with CONSOL coal were not as good as with the other coals tested in the present work, which may be attributed to possible oxidation and/or contamination.

The project team also continued its search for the suitable animation software to be adapted to the underground mining systems. Meanwhile work is progressing along the lines of updating the original open loop flow diagram that deals with the automatic control of the thrusting, advance, and rotation of the auger train which both cuts (extracts) and transports the coal across the face. The team is integrating the control systems into a deterministic mathematical equation for optimizing the mining and material flow rate in the operating system. The long range plan is to integrate the current deterministic equations in a suitable animation program with a number of adjustable and controllable parameters. This will enable coal operators and engineers to visualize how the variations can affect the safety, cost and production levels of the system.

    During the sixth quarter four boron-promoted cobalt catalysts were prepared by a new boriding process using diborane gas as the boriding agent. These catalysts were characterized by chemical analysis, BET, H/sub 2/ chemisorption, and x-ray diffraction. Temperature-programmed desorption spectra of H/sub 2/ were obtained for a sodium-promoted cobalt boride and a sodium-promoted Co/SiO/sub 2/. Four cobalt catalysts (unsupported, boron-promoted, sodium-promoted, and doubly-promoted) were tested for CO hydrogenation activity and selectivity at 1 atm and 3 to 4 temperatures in the range of 190 to 240/sup 0/C. About 10% of the surface of cobalt boride consists of reduced metallic cobalt. The addition of sodium to cobalt increases its binding energy with H/sub 2/ and its activation energy for H/sub 2/ adsorption. Boron does not affect the activity of cobalt; sodium decreases it by a factor of 10. Cobalt boride produces lighter hydrocarbon products relative to cobalt; sodium-promoted cobalt produces heavier products, more alcohols, and more CO/sub 2/. 29 references, 10 figures, 4 tables.

    The goal of this program is to demonstrate that a dichlorosilane-based reductive chemical vapor deposition (CVD) process is capable of producing, at low cost, high quality polycrystalline silicon for use in the manufacture of high efficiency solar cells. The feasibility of silicon generation from dichlorosilane (DCS) has been well established. The feasibility and optimization portions of the experimental reactor program have been completed, with a number of runs having been conducted over a broad range of conditions in an experimental CVD reactor. Activities relating to feed of commercially purchased DCS to an intermediate sized reactor and to construction of a Process Development Unit (PDU) to generate and feed DCS to one or more production scale reactors were suspended during the previous quarter because of the receipt of new safety-related information about DCS from Hazards Research Corp. Experimental data generated by Hazards Research Corp. indicate that DCS/air mixtures possess about four times the explosive severity potential as hydrogen/air mixtures, and that DCS/air mixtures are very readily ignited. As a consequence of this new information, designs and procedures for the intermediate reactor feed and PDU tasks were deemed inadequate and new designs incorporating new safety-related elements are being formulated. A preliminary economic evaluation of the Hemlock Semiconductor process has been completed. The analysis for a plant to generate 1000 metric tonne of silicon indicates a plant investment of $21.9 M, and a product selling price of $19.85/kg.

    Advanced integrated gasification combined cycle and pressurized fluidized bed combustion power system requires both hot gas desulfurization and particulate filtration to improve system thermal efficiency and overall performance. Few metal oxides were evaluated to be the sorbent candidate for hot gas desulfurization process. The use of waste iron oxide as a disposable metal oxide sorbent will alleviate the constraints imposed on iron oxides including the degradation of sulfur capacity and its physical attrition required for a regenerable sorbent. The very low cost of waste iron oxides and the elimination of the investment associated with sorbent regeneration make it attractive to replace currently developed sorbent candidates. However, the use of waste iron oxides indicates a significant increase of dust loading for particulate filtration. The slower the reaction rate the iron oxide and coal ash mixture is, the longer residence time and higher iron oxide to coal ratio are required. One of the key issue of the use of waste iron oxides as a disposable sorbent material relies on the capability of particulate filtration efficiency. The current back pulse cleaning of the dust cake had been evaluated; and the preliminary test results indicated that the simultaneous operation of hot gas desulfurization and particulate filtration is feasible. A parametric testing will be performed on hot gas desulfurization and particulate independently first. The independent test results will help optimize the test design and evaluation of the integration of hot gas desulfurization testing and particulate filtration testing to be completed in the first two quarters 1998.

Activities included the operation and modification of the Solvent Refined Coal Pilot Plant at Fort Lewis, Washington; the Process Development Unit P-99 at Harmarville, Pennsylvania; and research at Merriam Laboratory in Merriam, Kansas. The Pilot Plant processed Powhatan No. 5 Coal in the SRC-II mode of operation studying the effect of coal particle size and system temperature on coal slurry blending and the effect of carbon monoxide concentration in the reaction feed gas on process yields. January and February were spent completing installation of a fourth High Pressure Separator on Process Development Unit P-99 to better simulate operating conditions for the proposed Demonstration Plant. During March, one run was completed at P-99 feeding Pittsburgh Seam Coal from the Powhatan No. 5 Mine. Merriam investigations included a study of the effect of iron containing additives on SRC-I operation, the addition of carbon monoxide to the feed gas, utilization of a hydrogenated solvent (Cresap process solvent) in the SRC-I mode under both normal and short residence time operating conditions, and development of a simulated distillation technique to determine the entire boiling range distribution of product oils.

In the area of flue gas cleanup, our in-house research program is continuing its investigation into the causes of sorbent attrition in PETC's fluidized-bed copper oxide process for simultaneous SO/sub 2//NO/sub x/ removal. Interwoven with these tests is a series of spray dryer/electrostatic precipitator tests that are being conducted with the cooperation of Wheelabrator-Frye, Inc. This test series was completed this quarter, and the data show that when using a Kentucky coal, Wheelabrator-Frye's electrostatic precipitator provides excellent particulate control efficiency while using a spray dryer for sulfur dioxide removal. A unique project at Carnegie-Mellon University is looking at the concept of integrated environmental control for coal-fired power plants making use of precombustion, combustion, and postcombustion control, including systems for the simultaneous removal of more than one pollutant. The objective of this research is to develop a computer model and assessment for integrated environmental control systems that utilize conventional or advanced systems. The Liquid Phase Methanol Project Development Unit in LaPorte, Texas, was restarted after a successful shakedown run was completed. PETC has recently begun an in-house research project aimed at exploring the basic chemistry of liquefying coal in the presence of water under supercritical conditions. In the Alternative Fuels Technology Program, the Gulf Research and Development Company has completed the preliminary testing phase of its erosion test loop. Their results indicate that when pumping a coal-water slurry fuel through a flow loop, the erosion rate increases as velocity increases, suggesting a well-defined relationship between these two parameters.

    During the third quarter of this program, liquid junction devices based upon the semiconductors MoSe/sub 2/, MoS/sub 2/, GaAs, and CdSe have been evaluated. Lifetime testing of MoSe/sub 2/ and MoS/sub 2/ materials in acidic halogen electrolytes at constant current densities of 5 mA/cm/sup 2/ have shown excellent stability to date. For MoSe/sub 2/ single crystals in the electrolyte 1M HBr + 1M Br/sub 2/, short-circuit currents of 63 mA/cm/sup 2/ were achieved with a power conversion efficiency of 6.7% for 200 mW/cm/sup 2/ xenon light illumination. Transient potentiostatic measurements made on MoSe/sub 2/ in this electrolyte indicated little diffusion control, with exchange currents being of the order of 1 to 10 mA/cm/sup 2/. Good photoresponse of MoS/sub 2/ has been observed in 1M HBr + 1M Br/sub 2/. The performance of the natural crystal is comparable to the performance of a single-crystal MoS/sub 2/ in this electrolyte. CdSe thermally evaporated onto porous titanium gave efficiencies of about 4% with 100 mW/cm/sup 2/ xenon illumination. Experimental work was initiated on the dye sensitization of Fe/sub 2/O/sub 3/ and TiO/sub 2/ materials. Of the twelve dyes evaluated, little enhancement of the photoresponse of these materials was noted. Solid-state photoelectrochemical cells have been fabricated, based upon LiI. Cells of the configuration - cond. glass CdSe/LiI + PbI/sub 2//LiI/LiI + C + PbI/sub 2//cond. glass - were fabricated. Photoresponses up to 150 mV were observed.

    Rockwell has developed a reactor which allows rapid and uniform mixing of pulverized coal with heated hydrogen through the use of a rocket-engine-type injector. The hydrogen is partially heated by indirect heating and further heated by partial combustion with oxygen to supply the required process heat. The amount of hydrogen fed is being kept as low as practicable because of the recycle implication for a complete process. Successful operation of a water-cooled heat-exchange quench unit without plugging or degradation has been demonstrated. Char is separated from the vapor-phase material in a separator which is maintained at a sufficiently high temperature to allow vapor-phase removal of the liquid products. The effectiveness of the concept has been demonstrated in a series of tests. Substantial liquid yields and high overall conversions are possible. A high-pressure product recovery system contains two condensers which split the liquid product into heavy and light oil fractions. In addition, an adsorber bed BTX recovery system was installed. The new system functioned well after an initial shakedown, and they allow for better separation and recovery of the products. Evaluation showed a very high thermal efficiency and favorable economics compared with other liquefaction processes. Many potential advantages of the process were noted; however, most of these advantages remain to be demonstrated. During the first two quarters of the Phase IV effort modifications were made to the PDU to improve material balances; the PDU was activated and six successful tests were conducted; and supporting dense-phase flow, product refining and utilization, and material studies were initiated. The PDU facility modifications made to improve material balances were quite beneficial. Material and major elemental balances for the Phase IV tests are within 5% of closure, a contract target value.

    The purpose of this contract is to develop a process for converting light alkane gases to methyl chloride via oxyhydrochlorination using highly selective, stable catalysts in fixed-bed reactors designed to remove the large amount of heat generated, so as to control the reaction temperature. Further, the objective is to obtain the engineering data base necessary for developing a commercially feasible process and to evaluate the economics of the process. Several key technology areas were evaluated this quarter. The catalyst definition effort focused on the determination of the role of the Li and La promoters that have been found to be useful in enhancing Cu based oxyhydrochlorination of methane catalysts. Initial experiments show that the La acts to provide a much more active catalyst than the Cu only case. The role of the Li is ambiguous at this point. The Li enhances the stability of the La promoted catalyst, but gives only marginal improvement by itself This work will be continued, with additional emphasis on the analysis of the catalysts to determine the structural role that the promoters may play. The separation unit operation definition made significant progress by demonstrating in a laboratory system that a process solvent may be used to remove the product CH{sub 3}Cl from the reactor effluent stream. To date the data has been qualitative, but clear. Work will continue to gather the information possible in the laboratory to help with PDU design. An extensive amount of testing was performed on the chosen process solvent, Multitherm. A comprehensive review of all the thermal testing and associated FTIR, UV/VIS, and physical property testing is included in this report. This work shows that Multitherm should give the desired stability and solubility that are necessary to make the separation unit operation successful.

    This is the tenth quarterly report under DOE Contract No. DE-AC22-88PC88810, Development of Analytical Procedures for Coprocessing. The overall objective of the contract is to improve understanding of the fundamental chemistry of coprocessing. A primary objective is to evaluate methods to distinguish between compound classes originating from coal versus those originating from petroleum resid while a corollary objective is to provide detailed knowledge on the composition of coprocessing products. This report summarizes work conducted in support of the latter objective in which process development unit samples produced by HRI, Inc. are being subjected to detailed analysis. Coprocessing resid samples selected for detailed analysis were made under constant conditions except for variations in coal concentration or in the coal (New Mexico subbituminous or Texas lignite). The soluble material was separated into strong and weak acids, strong and weak bases, and neutrals. The predominant fraction from the ABN separations was the neutral fraction (67-81%). All of the polar fractions increase with increasing coal concentration. The concentration of saturates in the neutrals is high in a run with 33% subbituminous coal but drops substantially with either increasing coal concentration or the substitution of lignite for subbituminous coal. High temperature gas chromatography showed that both the neutral aromatics fractions and saturates fractions from all of the runs are extremely similar regardless of the coal concentration or coal type. The neutral aromatics fractions were further separated by ring number separation. Chromatograms were again very similar regardless of the initial coal concentration or coal type with most material eluting in the 3-ring to 6-ring region.

    Several promising leads that have developed during the course of this program are being evaluated in this phase of the study. These have been selected from those that can be economically evaluated within the time constraints of the program schedule. A detailed plan for evaluating these approaches was formulated. The individual steps that will be evaluated are: (1) Dewaxing of the distillate recycle solvent stream treating either 25% or 100% of the stream. (2) Hydrotreating the dewaxed distillate streams in a downflow fixed bed reactor. (3) Agglomerating the coal using both the 25% and 100% dewaxed-hydrotreated distillate streams. (4) Liquefying the as-received coal and the agglomerated coals using two different Mo-promoted hematite particulate catalysts. (5) Liquefying two different Mo-Fe impregnated coals. (6) Liquefying the two off-agglomerated, Mo-Fe impregnated coals. The effect of the presence of molybdenum in the 1050{degrees}F{sup +} will be determined by making comparisons in both Mo-containing and Mo-free full range V-131B process solvent. The solvents that will be used in this study are the full-range reconstituted Mo-containing V-131B from Run 262E and a Mo-free V-131B made up of 1050{degrees}F{sup +} bottoms from Run 258K V-131B and V-1074 distillate from Run 262E. The series of experiments are described and a chart has been prepared summarizing this series of runs. The plan requires significant exchange of samples between the different participants in the program with the schedule timed for providing the data for economic evaluation within the next quarterly reporting period.

    Resinite is a naturally occurring substance found in coal and derived from original plant resins. It is ubiquitous in North American coals. It makes up one to four percent by volume of most Illinois coals. It has been commercially exploited in the western USA for use in adhesives, varnishes and thermal setting inks. The overall objective of this project is to compare the properties of the resinite contained in Illinois Basin coals to resinite being commercially exploited in the western United States, and to recover the resinite from Illinois coals by microbubble column floatation techniques. The significance of this study is that it has the potential to show the way to recover a valuable chemical, resinite, from coal using only physical processing techniques. The value of the resinite at $1.00/kg or $0.50/lb makes it about fifty times more valuable than steam coal. The removal of resinite from coal does not decrease the value of the remaining coal in any way. The unique aspects are that: (1) it is the first examination of the resinite recovery potential of Illinois coal, (2) it integrates the latest characterization techniques such as density Gradient centrifugation, microspectrofluorometry, and gas chromatography- mass spectrometry, and (3) it uses microbubble column flotation to determine the resinite recovery potential. During this quarter samples were obtained, information from both the databases of both the Illinois State Geological Survey (ISGS) and the Pennsylvania State University (PSU) was obtained and evaluated, and EBCSP samples from the Herrin No. 6, the Springfield No. 5 and the Colchester No. 2 seams were analyzed petrographically and the resinites in these samples were characterized by fluorescence spectral analysis.

    The program objective is to demonstrate efficient removal of fine particulates to sufficiently low levels to meet proposed small scale coal combustor emission standards using a cleanup technology appropriate to small scale coal combustors. This to be accomplished using a novel particulate removal device, the Confined Vortex Scrubber (CVS), which consists of a cylindrical vortex chamber with tangential flue gas inlets. The clean gas exit is via vortex finder outlets, one at either end of the tube. Liquid is introduced into the chamber and is confined within the vortex chamber by the centrifugal force generated by the gas flow itself. This confined liquid forms a layer through which the flue gas is then forced to bubble, producing a strong gas/liquid interaction, high inertial separation forces and efficient particulate cleanup. During this quarter a comprehensive series of cleanup experiments have been made for three CVS configurations. The first CVS configuration tested gave very efficient fine particulate removal at the design air mass flow rate (1 MM BUT/hr combustor exhaust flow), but had over 20{double_prime}WC pressure drop. The first CVS configuration was then re-designed to produce the same very efficient particulate collection performance at a lower pressure drop. The current CVS configuration produces 99.4 percent cleanup of ultra-fine fly ash at the design air mass flow at a pressure drop of 12 {double_prime}WC with a liquid/air flow ratio of 0.31/m{sup 3}. Unlike venturi scrubbers, the collection performance of the CVS is insensitive to dust loading and to liquid/air flow ratio.

    The performance of the third type of catalytic membrane reactor configuration, with catalyst deposited in the membrane and no catalyst or inert materials in the tube side, was evaluated. The C{sub 2} selectivity obtained was about 10% due to the gas phase reaction in the empty tube side of the reactor. The membrane reactor with an oxygen-permeable dense membrane has been built. The use of a dense membrane will eliminate the loss of hydrocarbon from the tube side to the shell side, as observed in the Vycor glass membrane reactor. Also, air can be used as the oxygen source without contaminating the product. La/MgO was synthesized and will be used as the catalyst for the dense membrane reactor. This catalyst was reported in the literature to show significant improvement of C{sub 2} selectivity and yield for oxidative coupling of methane in a packed-bed reactor by using the operation mode of staged-feed of oxygen. A reactor mode for methane oxidative coupling in reactors with both distributed oxygen feed and C{sub 2} product removal was developed based on the general model of cross-flow reactors reported in the last quarterly report. A distributed oxygen feed could give rise to much higher C{sub 2} yield than the co-feed reactor as long as the space time is long enough. In the case of a two-membrane reactor, where oxygen is supplied by one membrane and products are removed through the other membrane, a high separation factor of C{sub 2} product to methane for the product-removal membrane is critical to achieve high C{sub 2} yield.

    As mentioned in the report on the previous quarter, the authors have turned their attention to studies of photochemically-induced-charge-transfer phenomena involving aromatic electron donors. Coal is a porous material and it has been demonstrated that there are ground-state charge-transfer-interactions between imbibed TCNE or TCNQ and the automatic systems in bituminous coals. The authors aim to develop a preliminary understanding of the ground and excited state donor-acceptor interactions and the charge-transfer phenomena in porous materials that are better-defined than coals. They are performing background examinations of a set of donors and acceptors in solution by cyclic voltammetry and uv-visible spectroscopy. These preliminary experiments are being followed by systematic studies of the adsorption of the donors and acceptors, individually and together into adjacent supercages of a series of cation-exchanged X- and Y-type faujasite zeolites. Ultraviolet-irradiation of these systems are being performed and electron paramagnetic resonance examination of the samples is being made for the presence of paramagnetic, one-electron, charge-transfer products. In related work performed by students supported by this contract, the authors have reached a good understanding of the interactions and molecular motions of free radical {pi} electron systems in the X- and Y-type faujasite zeolites. Luminescence spectroscopy may also be used to examine the doped zeolite samples in future experiments. The authors have begun to examine the donor-acceptor pairs: diphenylamine-benzophenone, nitroxyl and substituted nitroxyl radical-benzophenone, and aromatic hydrocarbon-unsaturated tetracyano hydrocarbon. The oxidation and reduction potentials and excitation energies of these systems are given. The aromatic hydrocarbon donors span the range of typical aromatic ring sizes found in bituminous, subbituminous and lignite coals.

    This project is divided into four tasks. We developed our Management Plan in Task 1. Task 2, Evaluation of Mechanisms in FGD Sorbent and Ash Interactions, focused on characteristics of binary mixtures of these distinct powders. Task 3, Evaluation of Mechanisms in Conditioning Agents and Ash, was designed to examine effects of various conditioning agents on fine ash particles to determine mechanisms by which these agents alter physical properties of ash. We began Tasks 2 and 3 with an extensive literature search and assembly of existing theories. We completed this phase of the project with publication of two special Topical Reports. In our literature reviews reported in Topical Reports 1 and 2, we emphasized the roles adsorbed water can have in controlling bulk properties of powders. During the next phase of the project we analyzed a variety of fly ashes and fine powders in the laboratory. The experiments we performed were primarily designed to define the extent to which water affects key properties of ashes, powders, and mixtures of sorbents and ashes. We have recently completed a series of pilot-scale tests designed to determine the effects that adsorbed water has on fabric filtration and electrostatic precipitation of entrained fly ash particles in actual flue gas environments. Under Task 4 we will issue our Final Report that will summarize the results of our laboratory and pilot-scale work and will also include a model of flue gas conditioning. Our efforts during this reporting quarter have been directed toward production of the Draft Final Report and the Flue Gas Conditioning Model. In addition to these efforts, we have prepared a paper for presentation at the Eleventh Annual Coal Preparation, Utilization, and Environmental Control Contractor`s Conference to be held in Pittsburgh in July, 1995.

    A summary of the work is excerpted here. Final design of an MHD channel for the ITC program POC test has been completed. The channel was designed to be capable of 1.5 MW {sub e} power output and a lifetime of 2000 hours. Emphasis was placed upon durability and reliability. Hence, specific measures were taken to design against channel damage due to electric faults. The life-limiting issues associated with electrochemical corrosion and erosion of gas-side surfaces were addressed by the use of various materials with proven wear characteristics in a coal-fired MHD channel environment. Pitting of prototypical sidewall coupons was observed in the CDIF workhorse testing. The most likely cause of the observed pitting, water leaks resulting from cooling water tube braze failures, has been remedied. New brazing procedures and isolation of the sidebar gas-side material from water contact will prevent sidebar pitting in the prototypical channel. Water-side corrosion tests reported in this quarterly report include the latest results of tungsten-copper elements at controlled pH, heat flux and voltage levels. In the combustion subsystem, efforts continued to focus on understanding and improving the current levels of slag recovery and seed utilization achieved by the combustor. Analytical support was also provided in the areas of slag rejection system operation, precombustor operation, and oil burner design modification. Channel data analysis activities continued in support of prototypical coupon testing at the CDIF. Analyses are presented on channel wall slagging behavior and sidewall voltage distributions.

    Microbial desulfurization is the use of ''bugs'' to remove sulfur from coal. Four projects illustrate the variety of ways in which microbes can be used to desulfurize coal. In the liquefaction program area, a joint effort between PETC and Catalytic, Inc., was established for process-modeling studies of two-stage coal liquefaction experiments at Wilsonville. Researchers at PETC have developed a process model for Integrated Two-Stage Liquefaction and are currently focusing on characterization of an engineering (ASPEN Public) simulator. The goal of this work is to establish realistic process performance indices for different reactor configurations and coal feedstocks based on heat and material balance calculations. In another liquefaction research effort this quarter, Hydrocarbon Research, Inc., started the first bench run under its new contract for research on low-severity, two-stage liquefaction. The run is planned for 29 days and will test nine separate operating conditions. Research in the field of magnetohydrodynamics (MHD) continued at the Avco Everett Research Laboratory (AERL). A significant achievement fiscal year was the first-time operation of the Avco MK VIII channel with the total power controlled and/or consolidated using nonresistive circuitry. An electrostatic precipitator (ESP) was delivered, installed, and tested at the DOE's MHD Coal-Fired Flow Facility at the University of Tennessee Space Institute. Shakedown tests of PETC's Continuous Life-Cycle Copper Oxide Test Facility are complete. This PETC facility will be used to conduct the first integrated process tests of the Fluidized-Bed Copper Oxide Process unit for the control of SO/sub 2/ and NO/sub x/. PETC has recently initiated a project to study the fundamental properties of coal surfaces by measuring the heat of immersion of coal and its associated mineral matter using a Setaram C-80 heat flow calorimeter.

    This project investigates a suitable catalyst system for the direct nitric oxide decomposition in post-combustion gas streams. This process does not use a reductant, such as the ammonia used in the Selective Catalytic Reduction (SCR) of NO{sub x} to nitrogen. Therefore, it is a greatly simplified process basically involving passing the flue gas through a catalytic converter. Catalysts are prepared by incorporating metal cations into zeolite supports according to ion exchange procedures widely used in preparation of metal/zeolite catalysts. Particular emphasis is given in this work on promoted Cu-exchanged zeolites, especially the catalyst systems Mg/Cu-ZSM-5 and Ce/Cu-ZSM-5, which are promising for NO conversion to nitrogen at typical flue gas O{sub 2} and NO levels and over the temperature range of 673--873{degrees}C. The effect of zeolite modification, copper exchange level and catalyst preparation conditions on the catalytic activity are studied in O{sub 2}-free, O{sub 2}-rich gases, as well as wet (2--20% H{sub 2}O) gas streams in a packed-bed microreactor. Characterization of catalysts is performed by XRD, STEM, TEM and ESR. During this quarter it was found that severe steaming (20% H{sub 2}O) of Na-ZSM-5 at temperatures above 600{degrees}C caused partial vitreous glass formation and dealumination. Unpromoted Cu-ZSM-5 catalysts suffer drastic loss of NO decomposition activity in wet gas streams at 500{degrees}C. Activity is partially recovered in dry gas. Copper migration out of the zeolite channels leading to CuO formation has been identified by STEM/EDX. In Ce/Cu-ZSM-5 catalysts the wet gas activity i`s greatly improved. CuO particle formation is less extensive and the dry gas activity is largely recovered upon removal of the water vapor.

    This investigation seeks to utilize fly ash in fired-clay products such as building and patio bricks, ceramic blocks, field and sewer tile, and flower pots. This goal is accomplished by (1) one or more plant-scale, 5000-brick tests with fly ash mixed with brick clays at the 20% or higher level; (2) a laboratory-scale study to measure the firing reactions of a range of compositions of clay and fly ash mixtures; (3) a technical and economic study to evaluate the potential environmental and economic benefits of brick manufacture with fly ash. Bricks and feed materials will be tested for compliance with market specifications and for leachability of pollutants derived from fly ash. The laboratory study will combine ISGS databases, ICCI-supported characterization methods, and published information to improve predictions of the firing characteristics of Illinois fly ash and brick clay mixtures. Because identical methods are used to test clay firing and coal ash fusion, and because melting mechanisms are the same, improved coal ash fusion predictions are an expected result of this research. If successful, this project should convert an environmental problem (fly ash) into valuable products - bricks. During this quarter, the authors set up the manufacturing run at Colonial Brick Co., provided an expanded NEPA questionnaire for DOE, made preliminary arrangements for a larger brick manufacturing run at Marseilles Brick Co., revised laboratory procedures for selective dissolution analysis, and began characterization of brick clays that could be mixed with fly ash for fired-clay products.

    To reduce their sulfur emissions, many coal-fired electric power plants use wet flue-gas scrubbers. These scrubbers convert sulfur oxides into solid sulfate and sulfite sludge, which must then be disposed of. Knowledge of scrubber sludge characteristics is necessary for the development of purification technologies which will make it possible to directly utilize scrubber sludges rather than landfilling them. This project is studying the use of minimal-reagent froth flotation as the purification process, using the surface properties of the particles of unreacted limestone to remove them and their associated impurities from the material, leaving a purified calcium sulfite/gypsum product. In the current quarter, research was focused on two different areas. The first part of this quarter the optimization of the feed slurry percent solids for the two inch water-only cyclone was completed. The optimization of the vortex finder, spigot diameter and inlet feed pressure was completed in the previous quarter. The second part of this quarter began the investigation of why water-only cycloning helps froth flotation performance. The hypothesis is that water-only cycloning scrubs the surface of the unreacted limestone. This scrubbing effect provides a clean calcium carbonate surface, which results in better flotation reagent adsorption. This study used the scanning electron microscope to investigate the surface of the unreacted limestone particles.

    Work this quarter focused on staged liquefaction. The effect of residence time on conversion in single pass experiments was found to be quite different for the subbituminous Belle Ayr Mine and bituminous Illinois No. 6 coals studied. With bituminous coal, conversion to soluble material is quite high and the limit of conversion is approached in only a few minutes. With a subbituminous coal, however, conversion is much lower and the limit of conversion is approached much more slowly. Short contact time (SCT) dissolution of Belle Ayr coal was studied as a possible first stage in a two-stage process. Conversion, hydrocarbon gas yield and hydrogen consumption were increased as residence time or temperature were increased. Conversion was also significantly increased by partial slurry recycle. Pyrite was found to be the most effective slurry catalyst for increasing conversion, followed by ammonium molybdate emulsion and finally nickel-molybdenum on alumina. Illinois No. 6 coal was liquefied in two stages. Conditions in the first stage dissolution were varied to determine the effect on upgradability in the second stage. An SCT (6 minute) coal dissolution stage is preferred over one at 30 minutes because hydrocarbon gas yield was much lower while overall oil yields for the combined dissolution and upgrading stages were nearly the same. Use of a NiMo/Al/sub 2/O/sub 3/ catalyst in a trickle-bed second stage resulted in a higher oil yield and lower product heteroatom content than use of the same catalyst in the slurry phase. The total oil yield was lower with a pyrite slurry catalyst than with a NiMo/Al/sub 2/O/sub 3/ slurry catalyst. With Belle Ayr coal and added pyrite, there was no change in total oil yield, conversion or product quality brought about by adding an 8-minute first stage at 450/sup 0/C (842/sup 0/F) to a 2-hour second stage operated at 420/sup 0/C (788/sup 0/F). 39 figures, 12 tables.

    Seventy-five people attended PVUSA`s ``Grid-Support PV: Application and Assessment`` workshop in San Francisco on June 9--10. Results from the Kerman project`s distributed benefits evaluation were presented, along with results of four Sandia-sponsored utility case studies. Presentations on SMUD`s and UPVG`s PV programs were given, and several speakers addressed broader issues, such as the role of distributed generation in the changing utility environment, utility restructuring, and PV markets and applications. SMUD`s 200-kW UPG system at their Hedge substation site in Sacramento, California was brought on line in early April and christened at a dedication ceremony on April 18. This system uses SSI modules mounted on twenty rows of UPG-designed one-axis tracking structures, with power fed to a tingle Omnion PCU. In May, SSI notified PVUSA that it would cease additional work on its US-1 system at Davis. Rather than continue development work on both of the system`s Blue Point PCUs, SSI requested to close out its contract with just one of the system`s two PCUs in operation. One unit, inverter ``A``, continued to fail after over two years of troubleshooting and repairs. The other unit, inverter ``B``, has operated reasonablywell, although it too has frequently tripped off line. The half system was mted at 67 kill, 23% less than expected based on one half of the contract target 174 kill. Subsequent I-V curves suggest much of the shortfall may be traced to a 15% shortfall in the dc array field`s maximum power. The EMT and US systems at six PVUSA sites generated nearly 750,000 kWh this quarter, the same energy used by about 500 homes over the same period. For the first half of 1994, the performance index, or ratio of actual to expected generation has exceeded 90%, for six of the twelve completed systems for which data are available. Five of the remaining six systems have generated between 80% and 90% of their expected output.

    The goal of the West Hackberry Tertiary Project is to demonstrate the technical and economic feasibility of combining air injection with the Double Displacement Process for tertiary oil recovery. The Double Displacement Process is the gas displacement of a water invaded oil column for the purpose of recovering oil through gravity drainage. The novel aspect of this project is the use of air as the injection fluid. The target reservoir for the project is the Camerina C-1,2,3 Sand located on the West Flank of West Hackberry Field in Cameron Parish, Louisiana. This reservoir has been unitized and is designated as the WH Cam C RI SU. If successful, this project will demonstrate that the use of air injection in the Double Displacement Process can economically recover oil in reservoirs where tertiary oil recovery is presently uneconomic.

Additional chemical, physical, and performance information on improved first-stage catalysts will be developed. Upgrading of ash concentrate to recover catalysts and improve low-rank coals will be assessed. The conversion of residual fractions to distillate by hydropyrolysis will be evaluated.

    The objective of this project is to produce one or more microorganisms capable of the organic and inorganic sulfur in coal. The original specific technical objectives of the project were to: (1) clone and characterize the genes encoding the enzymes of the ``4S`` pathway (sulfoxide/sulfone/sulfonate/sulfate) for release of organic sulfur from coal; (2) return multiple copies of genes to the original host to enhance the biodesulfurization activity of that organism; (3) transfer this pathway into a fast-growing chemolithotrophic bacterium; (4) conduct a batch-mode optimization/analysis of scale-up variables. By letter of September 3, 1991, from the Project Manager at Department of Energy, Pittsburgh Energy Technology Center, these objectives of this project were redirected toward finding and developing suitable vectors for Thiobacillus strains. All work on bacterial strains from Lehigh University was terminated since they did not contain desulfurization traits represented by the ``4S`` pathway.

    The project objective is to estimate the commercially recoverable tight gas reserves for the DOE priority basins. The work consists of a combination and integration of existing tight gas-in-place resources with engineering studies of recovery effectiveness and industry production histories into basin-wide estimates of tight gas reserves. The work will begin in the Greater Green River basin and will be carried forward to the Piceance and Uinta basins in the outyears. Technical work has been completed on the Greater Green River Basin area. As of the date of this memorandum, a final report is in preparation and exists in working draft stage. Analysis of all five plays has been completed and final figures are being quality controlled and checked. An updated production data tape for the Basin was received from Petroleum Information (PI) at the eleventh hour and has been processed to give us updated information and this data has been integrated with the previous analysis.

    The Department of Energy is currently supporting a program that will aid in the development of cross flow filtration technology as applied to combined cycle power generation with coal gasification. The stated overall goal is to gain information on both the operational and economic feasibility of the implementation of cross flow filtration in various gasifier options. Westinghouse has prepared a comprehensive program that will lead directly to these program goals in an efficient manner. The proposed program is composed of three major technical tasks. Task 1 is directed at the design and actual test of a cross flow filter at a DOE bench scale gasifier. Task 2 is composed of several smaller theoretical and experimental efforts that are intended to firm up areas where engineering and design principles are lacking or considered inadequate. The third task is intended to integrate the results of the first two tasks in a conceptual design and cost analysis such that proper economic perspective for the filter concept can be gained. A brief summary of the approach taken in the technical tasks is presented in the following discussion.

    This is the Third Technical Report to develop the Variable Wall Mining Machine(VWM), a patented mining system that has the potential of greatly improving the underground mining of coal and other flat-lying mineral beds by providing a greater safety for workers, a healthier human environment, and a higher productivity. One of the thrusts of this project is to analyze the adaptation of the VWM system to a dual duct ventilation system which separates the air for human breathing from the air which becomes contaminated from dust and dangerous gases. In conventional practice there is one zone in an underground working section where workers breathe the air used to carry away gases and dust. A proposed dual duct system divides the single zone into two zones: one for cutting and fragmentation and one for worker occupancy. It is both technically and economically impossible to ventilate longwall face with the conventional method when methane emission rate is higher than 1,500 cfM. The only available option to the methane problem is to pre-drain the methane before mining so the methane emission rate will be lower later during longwall mining. But it is questionable that enough methane can be predrained to significantly erase the explosibility problem. Contrariwise, the dual-duct gas control method requires significantly less ventilating air, resulting in large savings in fans, air course construction, and energy. The overall costs are measurably less. Since the cutting chamber is sealed, the dust and methane are extracted from the mine in a separate ventilation system at a speed which is independent of the general mine ventilation system.

    The interest group got under way effective January 1, 1994, with nine utility members, EPRI, Bechtel, and the Illinois Clean Coal Institute. DOE participation was effective October 1, 1994. The first meeting was held on April 22, 1994 in Springfield, Illinois and the second meeting was held on August 10--11, 1994 at Johnstown, Pennsylvania. Technical reviews were prepared in several areas, including the following: status of low rank coal upgrading, advanced physical coal cleaning, organic sulfur removal from coal, handling of fine coal, combustion of coal water slurries. It was concluded that, for bituminous coals, processing of fines from coal cleaning plants or impoundments was going to be less costly than processing of coal, since the fines were intrinsically worth less and advanced upgrading technologies require fine coal. Penelec reported on benefits of NOX reductions when burning slurry fuels. Project work was authorized in the following areas: Availability of fines (CQ, Inc.), Engineering evaluations (Bechtel), and Evaluation of slurry formulation and combustion demonstrations (EER/MATS). The first project was completed.

    This report describes the technical progress made on the Advanced Coal Conversion Process (ACCP) Demonstration Project from January 1, 1994, through March 31, 1994. This project demonstrates an advanced, thermal, coal drying process, coupled with physical cleaning techniques, that is designed to upgrade high-moisture, low-rank coals to a high-quality, low-sulfur fuel, registered as the SynCoal{reg_sign} process. The coal is processed through three stages (two heating stages followed by an inert cooling stage) of vibrating fluidized bed reactors that remove chemically bound water, carboxyl groups, and volatile sulfur compounds. After thermal processing, the coal is put through a deep-bed stratifier cleaning process to separate the pyrite-rich ash from the coal. Rosebud SynCoal Partnership`s ACCP Demonstration Facility entered Phase III, Demonstration Operation, in April 1992 and operated in an extended startup mode through August 10, 1993, when the facility became commercial. Rosebud SynCoal Partnership instituted an aggressive program to overcome startup obstacles and now focuses on supplying product coal to customers. Significant accomplishments in the history of the SynCoal{reg_sign} process development are shown in Appendix A.

    Shake flask tests were completed of microbial pyrite and HAP precursor removal from Rosebud subbituminous coal. Significant amounts of Ni, F, Mn, Cd, Co and Be were removed from this coal. Analyses in connection with leach column tests of Pittsburgh coal were completed and confirmed significant removal of Ni, F, Mn, Cd, Co and As from this coal. Although Hg was not removed from Pittsburgh coal by microbial attack, there was a correlation between HCl leaching of Hg from this coal and the extent of depyritization. Since HgS is soluble in HCl, the results suggest HgS is exposed by chemical and microbial dissolution of coal pyrite. Column tests with cleaned Indiana No. 5 coal are in progress and show significant early dissolution of Ni, Mn, Cd, Co and As. A final shake flask test with Kentucky No. 9 coal was begun. Pittsburgh coal with a low content of fines was shipped to the Idaho National Engineering Laboratory (INEL) in preparation for slurry column tests of HAP precursor removal. Project results were presented at the PETC contractor`s conference held in Pittsburgh. A project progress review meeting was also held with the PETC technical project monitor.

    The ultimate objective of this program is the commercial demonstration of an efficient, environmentally acceptable coal firing process suitable for implementation on melting furnaces throughout the aluminum industry. To achieve this goal, the program has been divided into two phases. Phase I has begun with the design and construction of a 350 pound (coal) per hour staged slagging cyclone combustor (SSCC) attached to a 7-ft diameter aluminum melting ladle furnace. Process development will culminate with a 1000 pph prototype SSCC firing a 40,000 pound capacity open hearth melting furnace at the Alcoa Laboratories. Phase II implementation is currently planned for Alcoa's Lafayette, IN, Works, where two of the ingot plant's five open hearth melting furnaces will be converted to utilize coal. In addition to confirmation of data gathered in Phase I, the effect of extended production schedule operation on equipment and efficiencies will be determined. This work would begin in 1982 pursuant to technical and economic evaluation of the process development at that time.

    Babcock & Wilcox (B&W) is conducting a five-year project aimed at the development of practical, cost-effective strategies for reducing the emissions of hazardous air pollutants (commonly called air toxics) from coal-fired electric utility plants. The need for air toxic emissions controls may arise as the U.S. Environmental Protection Agency proceeds with implementation of Title III of the Clean Air Act Amendment of 1990. Data generated during the program will provide utilities with the technical and economic information necessary to reliably evaluate various air toxics emission compliance options such as fuel switching, coal cleaning, and flue gas treatment. The development work is being carried out using B&W`s new Clean Environment Development Facility (CEDF) wherein air toxics emission control strategies can be developed under controlled conditions, and with proven predictability to commercial systems. Tests conducted in the CEDF provide high quality, repeatable, comparable data over a wide range of coal properties, operating conditions, and emissions control systems. Development work to date has concentrated on the capture of mercury, other trace metals, fine particulate, and the inorganic species hydrogen chloride and hydrogen fluoride.

    It is the goal of this research to provide the technical basis for development of a process to remove chlorine from coal prior to combustion, based on a thermal treatment process. Under the reaction conditions employed, the behavior of other trace elements of concern will also be evaluated. The recovery of the chlorine removed from the coal as a marketable byproduct, calcium chloride suitable for use as a road deicer, is also being investigated using a novel absorption/crystallization device. A value of 6.29 hr{sup {minus}1} was determined for the dechlorination rate constant of IBC-109 coal at 385{degrees}C, and an activation energy of 34.7 kcal/mol was obtained from an Arrhenius plot over the temperature range of 300--385{degrees}C. A significant removal of chlorine (84.3%) was attained while retaining 92% of the energy of the coal in the solid product by preheating the coal at lower temperatures prior to a six-minute reaction at 385{degrees}C. Volatiles lost during the thermal dechlorination may be recovered for their heating value, and/or as a source of chemical feedstocks; this aspect will require further study, but it appears that the overall energy balance on the system should prove to be favorable. The design of the bench scale fluidized bed thermal dechlorination unit has been completed, and components ordered. Operation of this system should provide the information required for further scale-up of the process.

    The overall goal of this work is to further develop and field test a system of stimulating oil and gas wells, which increases the effective radius of the well bore so that more oil can flow into it, by recording pressure during the gas generation phase in real time so that fractures can be induced more predictably in the producing formation. Task 1: Complete the laboratory studies currently underway with the prototype model of the instrumentation currently being studied. Task 2: Perform field tests of the model in the Taft/Bakersfield area, utilizing operations closest to the engineers working on the project, and optimize the unit for various conditions encountered there. Task 3: Perform field test of the model in DGPL jobs which are scheduled in the mid-continent area, and optimize the unit for downhole conditions encountered there. Task 4: Analyze and summarize the results achieved during the complete test series, documenting the steps for usage of downhole instrumentation in the field, and compile data specifying use of the technology by others. Task 5: Prepare final report for DOE, and include also a report on the field tests completed. Describe and estimate the probability of the technology being commercialized and in what time span. The project has made substantial technical progress, though we are running about a month behind schedule. Expenditures are in line with the schedule. Increased widespread interest in the use of DGPL stimulation has kept us very busy. The computer modeling and test instrumentation developed under this program is already being applied to commercial operations.

    In this Letter we will analyze the creation of the multiverse. We will first calculate the wave function for the multiverse using third quantization. Then we will fourth-quantize this theory. We will show that there is no single vacuum state for this theory. Thus, we can end up with a multiverse, even after starting from a vacuum state. This will be used as a possible explanation for the creation of the multiverse. We also analyze the effect of interactions in this fourth-quantized theory.

The objective of this investigation is to characterize the operation of a fan powered infrared burner (IR burner) at various gas compositions and ambient conditions and develop design guidelines for appliances containing PIR burners for satisfactory performance. The fan powered infrared burner is a technology introduced more recently in the residential and commercial markets. It is a surface combustor that elevates the temperature of the burner head to a radiant condition. A variety of metallic and ceramic materials are used for the burner heads. It has been demonstrated that infrared burners produce low CO and NO{sub x} emissions in a controlled geometric space. As the environmental regulations become more stringent, infrared burners are receiving increasing interests.

    The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent cases with those of other forecasting services, and discusses current topics related to the short-term energy markets. The forecast period for this issue of the Outlook extends from the second quarter of 1994 through the fourth quarter of 1995. Values for the first quarter of 1994, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available. The historical energy data, compiled into the second quarter 1994 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service. The cases are produced using the STIFS. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook. The EIA model is available on computer tape from the National Technical Information Service.

    The temperature dependence of the oxygen flux across the BaCe0G03 dense membrane (BCG membrane) tube was investigated. In the temperature range of 688C to 955C, the increase in the oxygen flux with temperature obeyed the Arrhenius law. An increase in the helium sweep flow membrane tube. rate in the tube side resulted in an increase in the oxygen flux through the The oxygen fluxes through the BCG dense membrane tube were measured at different oxygen partial pressures in the shell side. The oxygen flux increased with the oxygen partial pressure in the shell side. The BCG dense membrane was tested in a membrane reactor for the catalytic oxidative coupling of methane. The BCG membrane is not a complete combustion catalyst, and the catalytic activity of the BCG membrane was found to be much higher than the Argonne dense membrane. As the oxygen partial pressure in the shell side increased, the C2 decreased while the C2 yield remained unchanged, indicating that non-selective, reactions still played a significant role in the membrane reactor.

    The objectives of this project are to demonstrate that: The Mulled Coal process, which has been proven to work on a wide range of wet fine coals at bench scale, will work equally well on a continuous basis, producing consistent quality at a convincing rate of production in a commercial coal preparation plant. The wet product from a fine coal cleaning circuit can be converted to a solid fuel form for ease of handling and cost savings in storage and rail car transportation. A wet fine coal product thus converted to a solid fuel form, can be stored, shipped, and burned with conventional fuel handling, transportation, and combustion systems. During this fourth quarter of the contract period, activities were underway under Tasks 2 and 3. Sufficient characterization of the bench-scale testing and pilot-plant testing results enabled the design and procurement activities to move forward. On that basis, activities in the areas of design and procurement that had been initiated during the previous quarter were conducted and completed.

    During the first quarter of the above contract, all the elements of Task 1 were completed. The first quarterly report presented an overview of a wetland and its increasing use in industrial wastewater treatment. An idealized, reaction engineering description of wetlands was presented to demonstrate how the various processes that occur in a wetland can be modeled. Previous work on the use of wetlands to remove BOD, TSS, Phosphorus and Nitrogen was reviewed. Recent literature on the application of wetland technology to the treatment of petroleum-related wastewater was critically evaluated and an outline of the research plans for the first year was delineated. Further, our literature search (nominally completed under Task 1) unearthed more recent studies (some unpublished) and a summary was included in the second quarterly report. In the second quarterly report, results of our efforts on the construction of a laboratory-type wetland were also reported. Initial studies on the use of wetland amendments such as modified-clays and algae cells were presented and discussed. Adsorption of heavy metal ions, Cu{sup 2+} and Cr(VI) onto soils drawn from the laboratory-type wetland built as a part of this contract has been undertaken and these results are presented and discussed in this quarterly report. A number of studies on the design and preparation of modified-clays for the adsorption of Cr(VI) and {beta}-naphthoic acid (NA) has been carried out during this quarter and these are also described and discussed in this report. The choice of {beta}-naphthoic acid (NA) as an ionogenic organic compound was made on the basis of a recent personal communication to the Project Director that NA is a major contaminant in many oil and gas well wastewaters.

    The planned program falls under wetlands area research related to drilling, production, and transportation of oil and gas resources. Specifically the planned program addresses an evaluation of using cyclocraft to transport drill rigs, mud, pipes and other materials and equipment in a cost effective and environmentally safe manner to support oil and gas drilling and production operations in wetland areas. The cyclocraft is a proven hybrid aircraft that utilizes aerostatic and aerodynamic lift. This type of aircraft has considerable payload capacity, VTOL capability, high controllability, low operating cost, low downwash and high safety. The benefits of using a cyclocraft to transport drill rigs and materials over environmentally-sensitive surfaces would be significant. The cyclocraft has considerable cost and operational advantages over the helicopter. In 1992, Task 1, Environmental Considerations, and Task 2, Transport Requirements, were completed. In the first two quarters of 1993, Task 3, Parametric Analysis, Task 4, Preliminary Design, and Task 6, Ground Support, were completed. Individual reports containing results obtained from each of these tasks were submitted to DOE. In addition, through June 30, 1993, a Subscale Test Plan was prepared under Task 5, Subscale Tests, and work was initiated on Task 7, Environmental Impacts, Task 8, Development Plan, Task 9, Operating Costs, and Task 10, Technology Transfer.

    The objective of this project is to retrofit the previously developed High Efficiency Advanced Coal Combustor (HEACC) to a standard gas/oil designed industrial boiler to assess the technical and economic viability of displacing premium fuels with microfine coal. This report documents the technical aspects of this project during the tenth quarter of the program. The four hundred hours ``Proof-of-Concept System Test`` under Task 3 was completed during this quarter. The primary objectives were to obtain steady state operation consistently on coal only and increase carbon conversion efficiency from {approximately}95% to the project goal of 98%. This was to be obtained without increasing NO{sub x} emission above the project goal level of 0.6 lbs/MBtu ({approximately}425 ppM). The testing was also designed to show that consistent, reliable operation could be achieved as another prerequisite to the demonstration. The data were gathered and analyzed for both economic and technical analysis prior to committing to the long term demonstration. The Economic Evaluation was completed and work started on commercialization plan. During this reporting period, activities included sample analysis, data reduction and interpretation from all the testing during March and April. Following preliminary conclusions are drawn based on results evaluated: coal handling/preparation system can be designed to meet technical requirements for retrofitting microfine coal combustion; boiler thermal performance met requirement; NO{sub x} Emission can meet target of 0.6 lb/MBtu; combustion efficiencies of 95% could be met on a daily average basis, somewhat below target of 98%; economic playback very sensitive to fuel differential cost, unit size, and annual operating hours; and continuous long term demonstration needed to quantify ash effect and how to best handle.

    Progress during the eighth quarter of a three-year study was made in three task areas: (1) analysis of coals; (3) parametric testing of the target coals, and (4) analysis of samples from the combustion tests. Routines for automated analysis of coal and mineral associations were completed and are now functional on our new ISIS system. Work on data processing which led to the development of a new means of interpreting composition information from the SEM was also completed during the quarter. This work is expected to yield substantial benefits in understanding the ash transformations during combustion. Several additional ash and deposit samples were collected this quarter. Deposition results have been explained qualitatively and samples has been mounted for quantitative analysis. A detailed characterization of mixing and coalescence was performed during the quarter. Results indicate that combustion under stage conditions does not change the chemistry of the final ash produced. Specifically, both iron and potassium distributions in long residence time ashes did not change as a function of combustion conditions. Some differences were observed in the potassium distribution at shorter residence times. There was also a difference in the size distribution of particles formed during staged combustion. The nature and significance of these differences are still under investigation.

    In response to the third Clean Coal Technology Program solicitation, AirPol Inc. submitted a proposal for the design, installation and testing of the Gas Suspension Absorption (GSA) system at Tennessee Valley Authority`s (TVA) Shawnee Test Facility (STF). This low-cost retrofit project will demonstrate the GSA system which is expected to remove more than 90% of the SO{sub 2} from coal-fired flue gas, while achieving a high utilization of reagent lime. The host site facility will be the STF located at the Shawnee Fossil Plant in West Paducah, Kentucky. Over the past 15 years, the STF has served as a testground for flue gas desulfurization (FGD) systems. At the present time a semi-dry process employing 10 MW capacity spray dryer is being tested at the facility. Upon completion of the current spray dryer test, the GSA system will be tested for a period of eleven months. The GSA system brings coal combustion gases into contact with a suspended mixture of solids, including sulfur-absorbing lime. After the lime absorbs the sulfur pollutants, the solids are separated from the gases in a cyclone device and recirculated back into the system where they capture additional sulfur pollutant. The cleaned flue gases are sent through a dust collector before being released into the atmosphere. The key to the system`s superior economic performance with high sulfur coals is the recirculation of solids. Typically, a solid particle will pass through the system about one hundred times before leaving the system. Another advantage of the GSA system is that a single spray nozzle is used to inject fresh lime slurry.

    1981-03-30

    The A.P.T. Dry Plate Scrubber (DPS) uses a shallow, dense mobile bed of solid collector granules which move across a perforated plate. The gas stream containing fine particles and vapors is moved upward through the perforations to form high velocity gas jets. The fine particles are removed by inertial deposition onto the collector granules or by direct interception. Electrostatic forces also can be used to improve the collection efficiency and increase the adhesive forces between the particles and collectors. The DPS column consists of a series of collection stages (perforated plates) with the collectors either passing sequentially over each stage or being fed separately to each stage. The stages can be designed so as to promote the collection of large particles on the lower stages and the collection of fine particles and alkali vapors on the upper stages. The DPS is especially well suited for cleaning high temperature and pressure gases such as the effluent from a pressurized fluidized bed combustion (PFBC) process. The objective of this project is to conduct a bench scale experimental evaluation of the DPS at high temperature and pressure to determine its potential for controlling particulate and alkali vapor emissions from PFBC processes.

    A major expenditure to maintain oil and gas leases is the support of pumpers, those individuals who maintain the pumping systems on wells to achieve optimum production. Many leases are marginal and are in remote areas and this requires considerable driving time for the pumper. The Air Pulse Oil Pump System is designed to be an economical system for the shallow stripper wells. To improve on the economics of this system, we have designed a Remote Oil Field Monitor and Controller to enable us to acquire data from the lease to our central office at anytime and to control the pumping activities from the central office by using a personal computer. The advent and economics of low-power microcontrollers have made it feasible to use this type of system for numerous remote control systems. We can also adapt this economical system to monitor and control the production of gas wells and/or pump jacks.

    The objective of this project is to conduct extensive studies on the surfaces reactivity of pyrite by using electrochemical, surface analysis, potentiometric and calorimetric titration, and surface hydrophobicity characterization techniques and to correlate the alteration of the coal-pyrite surface with the efficiency of the pyrite rejection in coal flotation. The product as well as their structure, the mechanism and the kinetics of the oxidation of coal-pyrite surfaces and their interaction with various chemical reagents will be systematically studied and compared with that of mineral-pyrite and synthetic pyrite to determine the correlation between the surface reactivity of pyrite and the bulk chemical properties of pyrite and impurities. The surface chemical studies and the studies of floatability of coal-pyrite and the effect of various parameters such as grinding media and environment, aging under different atmospheres, etc., are directed at identifying the cause and possible solutions of the pyrite rejection problems in coal cleaning.

    A phase II study has been initiated to investigate surfactant-assisted coal liquefaction, with the objective of quantifying the enhancement in liquid yields and product quality. This report covers the fifth quarter of work. The major accomplishments were: (1) Completion of coal liquefaction autoclave reactor runs and related analysis with Illinois no. 6 coal at 400{degrees}C with and without surfactant and/or catalyst at pressures of 1700 psig; (2) A literature search into the effect that lignin has in the coprocessing of coal; and (3) Presentation of a report summarizing the first year of work on this task at the Annual Liquefaction Contractors Review Conference. Results from this quarter show that lignosulfonate surfactant continues to increase overall MAF conversion of Illinois no. 6 coal at temperatures up to 400{degrees}C and produces an improvement in light boiling fraction distillate over the base case of no surfactant addition.

    Progress during the ninth quarter of a three-year study of ash formation and deposition was made in several areas. One of the key contributions this quarter was the development of an enhanced method for classification of CCSEM data. This classification algorithm permits grouping and comparison of particles previously labeled as ``unclassifiable.`` A second analytical advancement, also made this quarter, provides more detailed information on the distribution of minerals in the coal and the potential for coalescence. This new multiple analysis technique is also applicable to ash and will permit identification of heterogeneous ash particles. Additional analyses of ash samples were also performed and it was found that the firing of Pittsburgh {number_sign}8 under staged combustion conditions yields an ash with a significantly larger particle size distribution than that obtained under conventional firing conditions, but without a significant change in composition. the size difference was noted previously, but the new classification algorithm allowed a detailed comparison of all composition groups, including unclassifiable particles, in the ashes. A mechanistic explanation for this behavior has been developed and is provided in the report. Finally, a paper documenting the new classification algorithm has been prepared and is scheduled for presentation at the March ACS meeting in New Orleans.

    This is the first quarterly technical progress report for the project. Although the contract was awarded on March 30, 1995 and Pre-Award Approval was given on January 26, 1995, the partners of this project initiated work on October 1, 1994. As such, this progress report summarizes the work performed from project inception. The production and injection data, reservoir engineering data, and digitized and normalized log data were all completed sufficiently by the end of the quarter to start work on the basic reservoir engineering and geologic stochastic models. Basic reservoir engineering analysis began June 1 and will continue to March, 1996. Design work for the 5 observation/core holes, oil finger printing of the cored oil sands, and tracers surveys began in January, 1995. The wells will be drilled from July--August, 1995 and tracer injection work is projected to start in October, 1995. A preliminary deterministic 3-D geologic model was completed in June which is sufficient to start work on the stochastic 3-D geologic model. The four proposed horizontal wells (two injectors and two producers) have been designed, equipment has been ordered, and the wells will be drilled from mid-August through September. Four existing steam injection wells were converted to hot water injection in March, 1995. Initial rates were kept low to minimize operational problems. Injection rates will be increased significantly in July.

    This document a quarterly report prepared in accordance with the project reporting requirements covering the period from July 1, 1992 to September 30, 1992. This report provides a summary of the technical work undertaken during this period, highlighting the major results. A brief description of the work done prior to this quarter is provided in this report under the task headings. The overall project scope of the engineering development project is to conceptually develop a commercial flowsheet to maximize pyritic sulfur reduction at practical energy recovery values. This is being accomplished by utilizing the basic research data on the surface properties of coal, mineral matter and pyrite obtained from the Coal Surface Control for Advanced Fine Coal Flotation Project, to develop this conceptual flowsheet. The conceptual flowsheet must be examined to identify critical areas that need additional design data. This data will then be developed using batch and semi-continuous bench scale testing. In addition to actual bench scale testing, other unit operations from other industries processing fine material will be reviewed for potential application and incorporated into the design if appropriate. The conceptual flowsheet will be revised based on the results of the bench scale testing and areas will be identified that need further larger scale design data verification, to prove out the design.

    The objective of this project is to increase oil production and reserves in the Uinta Basin by demonstrating improved completion techniques. Low productivity of Uinta Basin wells is caused by gross production intervals of several thousand feet that contain perforated thief zones, water-bearing zones, and unperforated oil-bearing intervals. Geologic and engineering characterization and computer simulation of the Green River and Wasatch formations in the Bluebell field will determine reservoir heterogeneities related to fractures and depositional trends. This will be followed by drilling and recompletion of several wells to demonstrate improved completion techniques based on the reservoir characterization. Transfer of the project results will be an ongoing component of the project. Technical progress for this quarter are discussed for subsurface and engineering studies.

    Froth flotation technique is an effective and efficient process for recovering of ultra-fine (minus 74 {mu}m) clean coal. Economical dewatering of an ultra-fine clean coal product to a 20 percent level moisture will be an important step in successful implementation of the advanced cleaning processes. This project is a step in the Department of Energy`s program to show that ultra-clean coal could be effectively dewatered to 20 percent or lower moisture using either conventional or advanced dewatering techniques. The cost sharing contract effort is for 36 months beginning September 30, 1994. This report discusses technical progress made during the quarter from April 1 - June 30, 1996.

    This report documents the technical aspects of this project during the ninth quarter of the program. During this quarter, the natural gas baseline testing at the Penn State demonstration boiler was completed, results were analyzed and are presented here. The burner operates in a stable manner over an 8/1 turndown, however due to baghouse temperature limitations (300{degrees}F for acid dewpoint), the burner is not operated for long periods of time below 75% load. Boiler efficiency averaged 83.1% at the 100 percent load rate while increasing to 83.7% at 75% load. NO{sub x} emissions ranged from a low of 0.17 Lbs/MBtu to a high of 0.24 Lbs/MBtu. After the baseline natural gas testing was completed, work continued on hardware optimization and testing with the goal of increasing carbon conversion efficiency on 100% coal firing from {approx}95% to 98%. Several coal handling and feeding problems were encountered during this quarter and no long term testing was conducted. While resolving these problems several shorter term (less than 6 hour) tests were conducted. These included, 100% coal firing tests, 100% natural gas firing tests, testing of air sparges on coal to simulate more primary air and a series of cofiring tests. For 100% coal firing, the carbon conversion efficiency (CCE) obtained this quarter did not exceed the 95-96% barrier previously reached. NO{sub x} emissions on coal only ranged from {approx} 0.42 to {approx} 0.78 Lbs/MBtu. The burner has not been optimized for low NO{sub x} yet, however, due to the short furnace residence time, meeting the goals of 98% CCE and <0.6 Lbs/MBtu NO{sub x} simultaneously will be difficult. Testing on 100% natural gas in the boiler after coal firing indicated no changes in efficiency due to firing in a `dirty` boiler. The co-firing tests showed that increased levels of natural gas firing proportionately decreased NO{sub x}, SO{sub 2}, and CO.

    Work has been initiated during this first quarter under all four program tasks and by all major participants as described. Task 1.0 activity (establish power plant reference design) concentrated upon definition of user requirements and establishment of power plant subsystem alternatives and characteristics. Task 2.0 work (stack and cell design development and verification) was initiated with a heavy emphasis upon test facilities preparation. A total of 27 laboratory cells were operated during this reporting period and a total of nine cells continued on test at the end of the quarter. Investigation of alternative anode and cathode materials proceeded; a dual-porosity anode was fabricated and tested. Over 10,000 endurance hours on a state-of-the-art cell carried-over from a previous program has been achieved and 1500 hours endurance has been obtained with sheet metal cells. Results presented for electrolyte structure development include comparative data for spray-dried and modified aqueous slurry process powders. Shake-down tests with a rotating disc electrode apparatus for fundamental measurements are described. Concept designs for both prototype and subscale stacks have been identified. Task 3.0 effort (development capability for full-scale stack tests) included preparation of an overall test plan to commercialization for molten carbonate fuel cells and of a functional specification for the tenth-scale stack test facility; drafts of both documents were completed for internal review. Cost-effective manufacturing assessment of available designs and processes was initiated. Task 4.0 work (develop capabilities for operation of stacks on coal-derived gas) included gathering of available contaminants concentration and effects information and preparation of initial projections of contaminant ranges and concentrations. Accomplishments to date and activities planned for the next quarter are described.

    Extraction trials on the new site were begun. The first trial, F80-1, was completed in Well No. 301 in October, 1979. Using a methane burner and an ignition service from TOR Developments, Inc., downhole burner ignition was readily achieved. Shale ignition occurred within two days. Combustion in the wellbore was so intense that the burner was lost, and subsequently shale combustion decreased and the trial was terminated. After some modification of equipment and procedures, the second trial, F80-2, was begun in late November, 1979. Combustion was achieved and the trial was still in progress at the end of the quarter.

    For new coal gasification systems, zinc titanate sorbents are being developed to remove sulfur from the hot product gas prior to its use in combined cycle turbines and high temperature fuel cells. Although most of the properties of these sorbents are very attractive, there are still concerns about durability over many sulfidation-regeneration cycles and zinc losses due to vaporization. Doping the zinc titanate with other metal ions could alleviate both concerns, which are the objectives of this project. During the first quarter of effort, several sorbent formulations were prepared and testing begun. The dopants presently under study are Ni, Cr, Cu, and Al. Crush strength results obtained to date show that Ni and Cu dopants have a large positive effect, while Cr gives a small improvement. Measurements were also made of sulfur capacity and sulfidation rates with a thermogravimetric analyzer. Of the three formulations, only the one containing Cr had a high sulfur capacity. X-ray measurements will be relied upon heavily to obtain an understanding of solubility effects and sulfidation mechanisms. Screening experiments will continue on the doped sorbents mentioned above next quarter, and Mg will be studied also.

    Wet flue-gas desulfurization units in coal-fired power plants produce a large amount of sludge which must be disposed of, and which is currently landfilled in most cases. Increasing landfill costs are gradually forcing utilities to find other alternatives. In principle, this sludge can be used to make gypsum (CaSO{sub 4}-2H{sub 2}O) for products such as plaster-of-Paris and wallboard, but only if impurities such as unreacted limestone and soluble salts are removed, and the calcium sulfite (CaSO{sub 3}) is oxidized to calcium sulfate (CaSO{sub 4}). This project is investigating methods for removing the impurities from the sludge so that high-quality, salable gypsum products can be made. Work done in the previous quarter concentrated on developing a low-cost froth flotation process that could remove limestone, unburned carbon, and related contaminants from the sludge while recovering the bulk of the calcium sulfite and gypsum. In the current quarter, experiments to remove impurities from the sludge using a water-only cyclone were conducted. The cyclone has been found to be effective for removing the coarser limestone impurities, as well as removing contaminants such as fine gravel and grinding-ball chips. These results show that the cyclone will be very complementary with froth flotation, which mainly removes the very fine impurities.

    The project will quantify the effect of the following pyrolysis conditions on the macropore structure and on the subsequent reactivity of chars: (a) pyrolysis heating rate; (b) final heat treatment temperature (HTT); (c) duration of heat treatment at HTT (or soak time); (d) pyrolysis atmosphere (N{sub 2} or O{sub 2}/N{sub 2} mixtures); (e) coal particle size (100--1000 {mu}m in diameter); (f) sulfur-capturing additives (limestone); and (g) coal rank. Pyrolysis experiments will be carried out for three coals from the Argonne collection: (1) a high-volatile bituminous coal with high ash content (Illinois {number_sign}6), (2) a bituminous coal with low ash content (Utah Blind Canyon) and (3) a lower rank subbituminous coal (Wyodak-Anderson seam). A systematic study was carried out in the past quarter to validate the mathematical model for ignition phenomena presented in the previous quarterly report. Model predictions of the effect of pyrolysis heating rate, particle size, and oxygen concentration on ignition behavior are in excellent agreement with experimental results. Moreover, our results show that the model can be used to estimate the particle temperature during ignition and the minimum ignition temperature for various process conditions.

    Over the past two quarters, our work has focused on three main areas. The first area of interest involved a reexamination of the rate laws that were formed in past quarters. A possible error was discovered for the analytical methods used in the o-cresol oxidation study and the data were corrected, yielding a new rate equation. The data for hydroxybenzaldehydes were studied again, this time as a system of parallel oxidation and thermolysis reactions. The second area in which progress was made was the study of the thermolysis of nitrophenols and dihydroxybenzenes in supercritical water. These investigations were needed to determine the effect that pyrolysis or hydrolysis had on our previous supercritical water oxidation experiments. Thirdly, we have continued to investigate the use of molecular orbital theory in the determination reactivity indices. A reactivity index, such as the enthalpy of formation, may be used in a structure-reactivity relationship to summarize the kinetics for the oxidation of phenolics in supercritical water. Progress in each of these areas is summarized.

    The primary objective of this project is to use {sup 129}Xe NMR to characterize the microporous structure of coals. We will use direct information on pore size, as well as indirect information from adsorption rates and evidence for intra/extraparticle diffusion, to characterize the connectivity of the micropore network. A second objective is to use {sup 129}Xe NMR to describe the effect of controlled opening of the micropores in a microporous carbon by oxygen chemi-sorption/desorption. Our experimental focus in this quarter has been the low power presaturation of the NMR signal of {sup 129}Xe adsorbed in coal. Preliminary work on this experiment was reported in the last quarter. Low power presaturation of {sup 129}Xe adsorbed in two coals produces a hole-burning effect in the adsorbed xenon NMR signals, indicating that these signals are broad due to overlap of a series of chemical shifts. Saturation transfer to the entire adsorbed xenon signal and to the extraparticle gas is observed with increasing presaturation time. Differences in timing of saturation transfer to the external gas have implications for the nature of the connectivity of the pore structures in coal.

    To develop a new class of permselective inorganic membranes, the authors have identified electroless plating as a potential route to deposit a thin metal film on a porous substrate. Electroless plating is a controlled autocatalytic deposition of continuous film on the surface of a substrate by the interactions of a metal salt and a chemical reducing agent. This method can give thin films of metals, alloys and composites on both conducting and nonconducting surfaces. The objective of this project is to develop thin film palladium membranes for separation of hydrogen in high temperature applications. The authors plan to use electroless plating to deposit thin palladium films on microporous ceramic and silver substrates. They plan to characterize the membrane in terms of permeability and selectivity for gas separation. To accomplish the research objective, the project requires three tasks: Development of a process for composite membrane formation; Characterization of fabricated composite membrane; and Development of theoretical model for hydrogen gas separation. During this quarter, the authors attempted to measure the diffusivity and permeability of hydrogen gas through the palladium composite membrane. While running the diffusion measurements at elevated temperature and pressure, leakage of hydrogen was observed. This is a serious problem and it needs to be resolved. Currently, they are working on this problem. During this quarter, they also designed a diffusion cell to test thin-film palladium membrane in tubular structure. The diffusion cell is being fabricated and assembled by a local machine shop.

    Both the Antek total sulfur analyzer and the modifications to the Shimadzu GC-14A gas chromatograph to be used for analysis for SO{sub 2} and H{sub 2}S were delivered during the quarter. Problems were faced during the installation and calibration phases of both instruments. By the end of the quarter we believe that the GC problems have been solved, but problems remain with the Antek analyzer. It appears that too much sulfur (as SO{sub 2}) reaches the UV detector and causes it to become saturated. This shows up as a maximum in the instrument calibration curve. At 200 psia, the capillary flow restrictor allows a total flow rate of about 180 sccm, and the maximum occurs at about 1 % H{sub 2}S in the calibration gas. Reducing the pressure so that the total flow is reduced to about 25 sccm shifts the calibration curve maximum to about 5.7% H{sub 2}S. It appears that we must reduce the total flow rate to the detector or provide additional dilution. This may be accomplished by increasing the resistance of the capillary restrictor, by diverting a portion of the flow leaving the pyrotube to vent, or adding an inert such as N{sub 2} to the gases exiting the pyrotube. We are in contact with Antek representatives about the problem. Both the atmospheric pressure and high pressure electrobalances were used during the quarter to study the regeneration of FeS in atmospheres of O{sub 2}/N{sub 2} or H{sub 2}O/N{sub 2}. In the atmospheric pressure unit the effects of temperature (600 - 800{degrees}C), flow rate (130 - 500 sccm), and reactive gas mol fraction (0.005 to 0.03 O{sub 2} and 0.1 to 0.5 H{sub 2}O) are being studied. Regeneration tests completed to date in the high pressure unit have utilized only O{sub 2}/N. and the parameters studied include temperature (600 - 800{degrees}C), flow rate (500 - 1000 sccm), pressure (1 - 15 atm) ad O{sub 2} mol fraction (0.005 - 0.03).

    Our efforts during the past quarter focused on the development of an image processing technique for characterizing the macropore structure of chars produced from Illinois No. 6 coal. Pyrolysis experiments were carried out in a microscope-stage reactor in inert and reacting atmospheres and at various pyrolysis heating rates. Particles from several pyrolysis runs were embedded in an epoxy resin block and polished sections . were prepared. Digital images of char particle cross-sections were acquired and analyzed to measure the structural properties of the chars. The macropore analysis procedure is presented here in detail. Future reports will present the data showing the effects of pyrolysis conditions on the macropore structure of Illinois No. 6 chars.

    The main objective of this research is to evaluate the desulfurization performance of novel sorbents consisting of different combinations of zinc, iron, vanadium and copper oxides; and to develop a sorbent which can reduce H{sub 2}S levels to less than 1 ppmv, which can stabilize zinc, making operations above 650{degrees}C possible, and which can produce economically recoverable amounts of elemental sulfur during regeneration. This objective will be accomplished by evaluating the sorbent performance using fixed-bed and TGA experiments supported by sorbent characterization at various reaction extents. In the seventh quarter, the screening of the promoted sorbents in the packed bed reactor was continued. The results of this work were presented at the 1992 University Coal Research Contractors, Review Conference at Pittsburgh, PA.

    The goal of this project is to test the feasibility of stabilizing coal slurry solids (CSS) wastes by directly seeding plants into the waste. This is not done conventionally because the waste can generate toxic amounts of sulfuric acid. Our approach is to neutralize the potential acidity by mixing fluidized bed combustion (FBC) waste into the slurry. If successful, this approach would both help dispose of FBC wastes while providing a more economical slurry stabilization technique. The project involves growing forage plants in CSS-FBC mixtures in the greenhouse. This is the first quarter of the project. We have designed the experiment, secured greenhouse space, purchased the seeds, collected and dried the FBC and CSS samples. The samples represent a typical range of properties. We retrieved two FBC and two CSS samples. One CSS sample appears to have a higher pyrite content than the other.

    The oxygen reduction reaction on a gold electrode in lithium carbonate melt was investigated to determine the influence of partial pressure of carbon dioxide and temperature on electrode kinetics and oxygen solubility by using cyclic Voltammetry and impedance analysis techniques. During this quarter, the impedance data were analyzed by a Complex Nonlinear Least Square (CNLS) Parameter estimation program to determine the kinetic and the mass transfer related parameters such as charge transfer resistance, double layer capacitance, solution resistance, and Warburg coefficient. The estimated parameters were used to obtain the C0{sub 2} reaction orders and apparent activation energies for the exchange current density and the mass transfer parameter (D{sub o}{sup {1/2}}C{sub o}*).

    The overall objective of this project is to show how gas can flow from the rock matrix to natural or induced fracures and be commercially produced. Flow of gas within the rock matrix has been shown to be largely controlled by sheet-like pores at grain boundaries, which are pressure sensitive. In this quarterly report, progress is reported in the following areas of advanced core analysis of low permeability gas sands: (1) surface area measurements; (2) helium porosimetry; (3) comparison of permeabilities for preserved cores and for cores subjected to drying; (4) pore space and fractures as related to diagenesis of multiwell sandstones; and (5) imbibition behavior of tight sands. 5 refs., 8 figs.

    The objective of this research program is to determine the feasibility of the alga Botryococcus braunii as a biocatalyst for the photosynthetic conversion of flue gas CO{sub 2} to hydrocarbons. The research program involves the determination of the biocatalytic characteristics of free and immobilized cultures of Botryococcus braunii in bench-scale studies, and the feasibility study and economic analysis of the Botryococcus braunii culture systems for the conversion of flue gas CO{sub 2} to hydrocarbons. The objective of the third quarter of this research program was to determine the growth and hydrogen formation characteristics of free and immobilized cells of Botryococcus braunii in bench-scale photobioreactors. Raceway and inclined surface type bioreactors were used for free cell and immobilized cell studies respectively. The free cell studies with air and CO{sub 2} enriched air [10% (v/v) CO{sub 2} in air] in media with and without NaHCO{sub 3} were conducted.

    A phase 2 study was initiated to investigate surfactant-assisted coal liquefaction, with the objective of quantifying the enhancement in liquid yields and product quality. This publication covers the first quarter of work. The major accomplishments were: the refurbishment of the high-pressure, high-temperature reactor autoclave, the completion of four coal liquefaction runs with Pittsburgh No. 8 coal, two each with and without sodium lignosulfonate surfactant, and the development of an analysis scheme for the product liquid filtrate and filter cake. Initial results at low reactor temperatures show that the addition of the surfactant produces an improvement in conversion yields and an increase in lighter boiling point fractions for the filtrate.

    The key issues addressed this quarter were related to operational problems in the coal feed system, namely, the inability to accurately measure all of air entering the system, and plugging of coal in the feed lines due to poor entrainment. Both of these problems caused unacceptable uncertainty and/or fluctuations in the operating conditions and therefore required solutions. The coal entrainment problem was solved by installing a new educator designed for entraining solids in gas streams. All of the air entering the reactor now flows through the educator, either as motive air or through the suction air inlet. This ensures that the coal is entrained at relatively high velocity, so that it will flow to the reactor without forming slugs in the lines. A new feeder shroud was also installed with an air jet directed towards the auger to sweep off the tip in order to reduce pulsations when feeding coal. The problems associated with accurately metering the air have been somewhat more difficult to resolve. New strategies for completely closing the system have been tested and look promising. A new flowmeter was also purchased with cost sharing funds to directly measure the air flow rate of the two phase stream (after the coal injection point). If the system can be operated without leaks, then the changes will provide two independent measurements of the air flow to ensure accuracy. If the system cannot be sealed, the new flowmeter will still provide reliable measurement of the air flow and permit proper operation of the combustor. Consequently, we feel that the problems have been resolved and we look forward to a productive next quarter.

    The mixed iron/alumina pillared clay catalysts and clay-supported iron catalysts have been shown in previous reports of this project to significantly improve yields of heptane-soluble products obtained in the liquefaction of both as received and acid-exchanged Wyodak subbituminous coal and Blind Canyon bituminous coal. In this quarter, the soluble product (LSW) obtained from the noncatalytic low-severity liquefaction of Wyodak coal was used as a feed to determine the activity of iron based catalysts for the hydrogenation and depolymerization steps. Comparison data for liquefaction of the soluble LSW with other catalysts were desired, and these data were obtained for a dispersed form of iron sulfide, prepared via iron hydroxyoxide (PETC method). The iron oxyhydroxide catalyst was directly precipitated on LSW product using either water or ethanol as the solvent. An insight into the functioning of the mixed iron/alumina pillared clay in coal liquefaction was investigated by preparing and studying an iron oxoaluminate structure. An investigation of new methods for the production of tetralin soluble iron oxometallate catalysts and the determination of their catalytic activities was continued in this quarter. The hydrogenation activity of iron oxoaluminate was investigated using pyrene and 1-methylnaphthalene as the test compounds, and results were compared with thermal reactions. In order to determine the loss of activity, recovered catalyst was recycled a second time for the hydrotreating of pyrene. Reaction of 1-methylnaphthalene with iron oxoaluminate also gave very high conversion to 1- and 5-methyltetralins and small amount of 2- and 6-methyltetralins. Liquefaction of Wyodak subbituminous and Blind Canyon bituminous coal was investigated using an in situ sulfided soluble iron oxoaluminate catalyst.

    An investigation of new methods for the production and utilization of tetralin-soluble iron oxometallate precursors for coal liquefaction catalysts was continued in this quarter. Further descriptions of the catalytic activities of the sulfided forms were obtained. The hydrogenation activities of catalysts derived from iron oxotitanate and cobalt oxoaluminate were investigated using pyrene as a the test compound, and results were compared with thermal reactions. The hydrogenation activity of iron oxotitanate was superior to other catalysts including iron oxoaluminate. The hydrogenation activity of cobalt oxoaluminate was similar to that of iron oxoaluminate reported in previous quarterly report. The liquefaction of Wyodak subbituminous coal was investigated using in situ sulfided iron oxotitanate catalyst. In order to improve the usefulness of iron oxoaluminate as a liquefaction catalyst, iron oxoaluminate was supported on acid-treated montmorillonite (K-10). Supporting the iron oxoaluminate on an acidic support significantly improved the hydrogenation activity of iron oxoaluminate. The hydrocracking activity was increased by a large factor. Thus the aluminate and titanate structures surrounding the pyrrhotite that forms during sulfidation have a beneficial effect in preventing deactivation of the iron sites, and the presence of the acidic sites in the clay results in effective catalytic synergism between catalyst and support. These clay-supported iron oxometallates are highly promising catalysts for coal liquefaction. Iron oxyhydroxide and triiron supported on acid-treated montmorillonite (K-10) were tested for the liquefaction of ion-exchanged Wyodak (IEW) to minimize effects of the coal mineral matter. Both sulfided catalysts gave very high conversions of coal to THF-soluble and heptane-soluble (oils) products.

    IGT has developed a microbial culture Rhodococcus rhodochrous, designated as IGTS8, that is of specifically cleaving carbon-sulfur bonds in a range of organosulfur model compounds and is capable of removing organic sulfur from coal and petroleum without significantly sacrificing the calorific value of the fuel. Although IGTS8 possesses the ability to specifically remove organic sulfur from coal, a major research need is to develop improved strains of microorganisms that possess higher levels of desulfurization activity and therefore permit favorable biodesulfurization process conditions. During the past quarter, promoter probe vectors thought to possess promoter inserts were isolated. Two new promoter probe vectors were constructed: pRCAT2; which is pRAT1 (second quarterly report) with the BamHI site removed, and pRCAT3; which is pRCAT2 with a synthetic oligonucleotide inserted at the HindIII site that will allow a wider range of restriction fragments to be examined for promoter activity including the fragments from the twenty mutants isolated from the Rhodococcus strains exhibiting increased resistance to chloramphenicol. Sequence analysis of six of these mutants has been initiated, computer comparisons made, and base change confirmation is in progress. As research to isolate strong Rhodococcus promoters is the goal, the promoter for the 16S ribosomal RNA structural gene is a good candidate for a strong promoter based on analyses of the 16S RNA gene in other species. Since the sequence of the 16S RNA gene is well conserved among species, straightforward techniques are available to isolate the promoter and such efforts are in progress.

    This document is the fifteenth quarterly technical progress report under Contract No. DE-AC22-92PC921 `Development of Vanadium- Phosphate Catalysts for Methanol Production by Selective Oxidation of Methane` and covers the period October-December, 1996. Vanadium phosphate, vanadyl pyrophosphate specifically, is used commercially to oxidize butane to maleic anhydride and is one of the few examples of an active and selective oxidation catalyst for alkanes. In this project we are examining this catalyst for the methane oxidation reaction. Initial process variable and kinetic studies indicated that vanadyl pyrophosphate is a reasonably active catalyst below 5000{degrees}C but produces CO as the primary product, no formaldehyde or methanol were observed. A number of approaches for modification of the phosphate catalyst to improve selectivity have been tried during this project. During this quarter we have obtained surface areas of catalysts prepared with modified surface acidity. The results confirm the enhanced activity of two of the modified preparations in methanol conversion (a test reaction for surface acid sites). In previous work we noted no improvement in methane oxidation selectivity for these catalysts. Surface areas, surface analysis by XPS, and bulk analysis by ICP-AA have been obtained for vanadyl pyrophosphate promoted by Cr, Cu, and Fe. These data indicate that roughly one tenth of the surface metal atoms are promoter. A similar analysis was obtained for the bulk. Preliminary examination of binding energies suggests a slightly more reduced surface for the Cr and Fe promoted catalysts which exhibit a significant selectivity to formaldehyde in methane oxidation. A more detailed kinetic model has also been developed to aid in comparing the promoted catalysts and is discussed. Plans for the coming months are outlined.

    A potentially new use for Illinois coal is its use as a fuel injected into a blast furnace to produce molten iron as the first step in steel production. Because of its increasing cost and decreasing availability, metallurgical coke is now being replaced by coal injected at the tuyere area of the furnace where the blast air enters. The purpose of this study is to evaluate the combustion of coal during the blast furnace injection process and to delineate the optimum properties of the feed coal. This proposal is a follow-up to one funded for the 1992--1993 period. It is intended to complete the study already underway with the Armco Inc. Steel Company and to initiate a new cooperative study along somewhat similar lines with the Inland Steel Company. The results of this study will lead to the development of a testing and evaluation protocol that will give a unique and much needed understanding of the behavior of coal in the injection process and prove the potential of Illinois coals for such use. During this quarter a sample of the feed coal that is being used for injection into the No. 7 Blast Furnace of Inland Steel has been analyzed petrographically and compared to both the Herrin No. 6 coal and Armco feed coal. Additional characterization is underway and an advanced program of pyrolysis and reactivity testing has been initiated.

    The objective of this study is to obtain data on the rates of reaction between, hydrogen sulfide (H{sub 2}S) and uncalcined calcium-based sorbents under operating conditions relevant to first stage (carbonizer) of Advanced Two-Stage Pressurized Fluidized-Bed Combustors (PFBC). In these systems the CO{sub 2} partial pressure in the first stage generally exceeds the equilibrium value for calcium carbonate decomposition. Therefore, removal of sulfur compounds takes place through the reaction between H{sub 2}S and calcium carbonate. To achieve this objective the rates of reaction between hydrogen sulfide and uncalcined calcium-based sorbents will be determined by conducting tests in pressurized thermogravimetric analyzer (TGA) and high-pressure/high-temperature fluidized-bed reactor (HPTR) units. The effects of sorbent type, sorbent particle size, reactor temperature and pressure, and CO{sub 2} and H{sub 2}S partial pressures on the sulfidation reaction rate will be determined. During this quarter, the high-pressure thermogravimetric analyzer (HPTGA) unit was installed and the shakedown process was completed. Several tests were conducted in the HPTGA unit to establish the operating procedure and the repeatability of the experimental results. Sulfidation by conducting the baseline sulfidation tests.

    Activities this quarter involved all phases of the project plus a meeting of the Joint Committee in Tokyo. Detailed mapping of the exposure facility is scheduled to be completed during the week of August 14, 1989. Both electric and magnetic fields should be available for tests of the components of the tether and blood sampling system for the neuroendocrine pilot study in September 1989. The groups for the social behavior study are stabilizing appropriately. Details on the formation of the groups and their status has been provided. Dr. Coelho has included information related to aspects of the social experiment ranging from age estimation in baboons through the cardiovascular consequences of psychosocial stress. In addition, a draft manuscript is included on the data from the previous experiments which describes the effects of 30 and 60 kV/m electric fields on the social behavior of baboons. Tests of the blood handling procedures and analysis methods have been completed. With the exception of the catecholamine analyses, the handling procedures and variability in replicate measurements are satisfactory. Logistic and practical considerations now weigh strongly against including the analysis of the blood samples for catecholamines. Preliminary tests indicate that a sampling procedure which will work for the other compounds is probably not satisfactory for the catecholamines.

    The goal of this project is to test the feasibility of stabilizing coal slurry solids (CSS) wastes by directly seeding plants into the waste. This is not done conventionally because the waste can generate toxic amounts of sulfuric acid. Our approach is to neutralize the potential acidity by mixing fluidized bed combustion (FBC) waste into the slurry. If successful this approach would both help dispose of FBC wastes while providing a more economical slurry stabilization technique. The project involves growing forage plants in CSS-FBC mixtures in the greenhouse. This is the second quarter of the project. We have designed the experiment, secured greenhouse space, purchased the seeds, collected, dried, and are analyzing the FBC and CSS samples. The samples represent a typical range of properties. We retrieved two FBC and two CSS samples. One CSS sample had a relatively high CaCO{sub 3} content relative to the pyrite content and will require no FBC to neutralize the potential acidity. The other CSS sample will require from 4.2 to 2.7% FBC material to neutralize its potential acidity.

    Work proceeded this quarter mainly under three program tasks. Under Task 1.0, the four candidate power plant configurations were ranked and the Steam Injection System was recommended as the reference plant design. The Steam Injection System was chosen based on its overall simplicity, high performance level, balance of plant state-of-technology readiness and economic attractiveness. Work was initiated on refinement of fuel cell piping costs. Under Task 2.0, work continued on cell component (anode, cathode, current collector and electrolyte) development and stack design and analysis. Corrosion test results after 1000 hours in fuel gas and 3000 hours in cathode gas are reported for 310SS, 316SS, 446SS, chromium, IN690, and GE2541. In the cathode environment, 310SS and GE2541 show good thermal cycling properties, whereas the other alloys show scale spalling during thermal cycling. Examination of a Ni-clad 316SS anode current collector tested in a cell for 2000 hours shows second phase precipitates along the grain boundaries of the nickel. Experiments with different grades of nickel in an anode atmosphere were started in order to evaluate the effects of impurities present in the metals. Under Task 4.0, work continued on installation of the bench scale single cell test facilities, one atmospheric and one pressurized (up to 10 atm), which will be used in cell testing with contaminants in the fuel and oxidant.

A number of alternate cathode materials were fabricated and tested for conductivity, solubility and stability. A new conductivity measurement device has been partially constructed. Under Task 4.0, testing of the effects of hydrocarbons in the fuel on the operation of carbonate fuel cells was completed. This series of tests has shown that small amounts of organic compounds do not adversely affect fuel cell operation. Testing of a cell with H/sub 2/S contamination in the fuel has proceeded for over 1700 hours. Cell performance decreased with increasing concentrations of H/sub 2/S, as would be expected, but also recovered substantially when clean fuel gas was introduced for a period of 378 hours. (WHK)

Under Task 4.0, studies continued to identify chemical reactions that might occur between fuel cell anode material and a number of organic compounds which could occur in fuel gases. The addition of several substances showed little effect on catalytic activity in a tube furnace or cell performance except for carbon plugging of a fuel line following ethanol addition. In addition, two cells were run this period to determine the effects of H/sub 2/S contamination on cell performance. Both tests were terminated (after 480 hours and 1450 hours of testing) due to test equipment operational problems. (WHK)

    High hydrocracking and liquefaction activity can be achieved with 10 wt.% of sulfided clay-supported iron catalysts. Further tests and demonstrations of this activity were required. Iron hydroxyoxide was generated on acid-treated montmorillonite. The new batch of catalyst exhibited high hydrocracking activity, Three hour tests with the solubilized intermediate from low-severity treatment of Wyodak coal (LSW) gave a high conversion (45%) of the heptane-insoluble LSW intermediate to heptane-soluble products. An investigation of new methods for the production of catalysts from tetralin-soluble iron oxometallates and the determination of their catalytic activities was continued in this quarter. Iron oxotitanate and iron oxoaluminate gave very high conversions of LSW to heptane solubles (61% and 54%, respectively). The high yields of heptane soluble products obtained with these catalysts offers a potential for use in liquefaction stages with solubilized coal, or at least serve as a model for producing active catalysts via mixed metal oxides. Methods for successfully testing dispersed iron catalysts with the low-severity intermediate were also devised. Catalyst recovered from the dispersed iron hydroxyoxide-catalyzed reaction of ion-exchanged Wyodak gave a high conversion (47%) of LSW to heptane solubles.

    Vortec Corporation`s Phase III development contract DE-AC22-91PC91161 for a ``Coal-Fired Combustion System for Industrial Process Heating Applications`` is project funded under the DOE/PETC advanced combustion program. This advanced combustion system research program is for the development of innovative coal-fired process heaters which can be used for high temperature melting, smelting and waste vitrification processes. The process heater systems to be developed have multiple use applications; however, the Phase III research effort is being focused on the development of a process heater system to be used for producing value added vitrified glass products from boiler/incinerator ashes and industrial wastes. The primary objective of the Phase III project is to develop and integrate all the system components, from fuel through total system controls, and then test the complete system in order to evaluate its potential marketability. During the past quarter, the designs of the remaining major components of the integrated system were completed and the equipment was ordered. DOE has elected to modify the scope of the existing R&D program being conducted under this contract to include testing of a simulated TSCA incinerator ash. The modification will be in the form of an additional Task (Task 8 -- TSCA Ash Testing) to the original Statement of Work.

    A novel technique for selectively coagulating and separating coal from dispersed mineral matter has been developed at Virginia Tech. The process, Selective Hydrophobic Coagulation (SHC), has been studied since 1986 under the sponsorship of the US Department of Energy (Contracts AC22-86PC91221 and AC22-90PC90174). The SHC process differs from oil agglomeration, shear or polymer flocculation, and electrolytic coagulation processes in that it does not require reagents or additives to induce the formation of coagula. In most cases, simple pH control is all that is required to (1) induce the coagulation of coal particles and (2) effectively disperse particles of mineral matter. If the coal is oxidized, a small dosage of reagents can be used to enhance the process. During the quarter, the Anutech Mark IV surface force apparatus was used to generate surface force-distance data for the mica/dodecylamine hydrochloride system (Task 2.1.1). Work to characterize the hydrophobicity of this system and the mica/DDOA{sup {minus}} system was also initiated (Task 2.1.2). In Task 3, the mixing/coagulation characteristics of a small Kenics static mixer/agitation system have been investigated (Task 3.2.1), a lamella thickener for the recovery of coagula has been built (Task 3.3.1), and the test program for the recovery of coagula by column flotation has been initiated (Task 3.3.4).

    Work was done in three tasks during the first quarter. In Task 1, a new SCR reactor system has been built, complete with on-line GC and MS analyses. The GC is used to monitor the N{sub 2} product so the NO{sub x} > N{sub 2} conversion can be calculated. The MS is used to analyze the N{sub 2}0 concentration. In addition, a wet analytical technique has been established for SO{sub 3} analysis. The new SCR system and the SO{sub 3} analytical technique have been subjected to shakedown tests with success. Along with the existing SCR reactor system, there are now two systems that are being run independently. In Task 2, a procedure for the synthesis of stable Fe{sub 2}O{sub 3} Pillared clay has been established. Inductive coupled plasma spectrometric analysis (ICP) has been used to analyze the chemical composition of the Fe{sub 2}O{sub 3} Pillared clay. Preliminary results for the SCR activities of the Fe{sub 2}O{sub 3} pillared clay are obtained in Task 3. The results show that the activities are near that of the commercial V{sub 2}O{sub 5}/TiO{sub 2} catalysts. However, the SO{sub 2}-to-SO{sub 3} conversion is substantially lower with the pillared clay catalyst, which could be an important advantage.

    The overall objective of this 29-month program is to develop and verify the design of a prototype molten carbonate fuel cell stack which meets the requirements of 1990's competitive coal-fired electrical utility central station or industrial cogeneration power plants. During this quarter, effort was continued in all four major task areas: Task 1 - system studies to define the reference power plant design; Task 2 - cell and stack design, development and verification; Task 3 - preparation for fabrication and testing of the full-scale prototype stack; and Task 4 - developing the capability for operation of stacks on coal-derived gas. In the system study activity of Task 1, preliminary module and cell stack design requirements were completed. Fuel processor characterization has been completed by Bechtel National, Inc. Work under Task 2 defined design approaches for full-scale stack busbars and electrical isolation of reactant manifolds and reactant piping. Preliminary design requirements were completed for the anode. Conductive nickel oxide for cathode fabrication has been made by oxidation and lithiation of porous nickel sheet stock. A method of mechanizing the tape casting process for increased production rates was successfully demonstrated under Task 3. In Task 4, theoretical calculations indicated that hydrogen cyanide and ammonia, when present as impurities in the stack fuel gas, will have no harmful effects. Laboratory experiments using higher than anticipated levels of ethylene showed no harmful effects. Components for the mobile test facility are being ordered.

During the past quarter, calculations were carried out under Subtask 2.3 (Predicting Optimum Conditions Using the Extended DLVO Equation) to explain the selectivity window that occurs between pH 7--9 in the SHC process. These calculations suggest that particle interactions involving the edge surfaces of clay are the most important, while interactions involving silica and face surfaces of clay are not as important. Experiments were also continued under Subtask 3.3 (Advanced Separation Methods) to investigate the performance of a centrifuge for separating hydrophobic coagula from dispersed mineral matter. These tests show that coagula recovery increases with centrifugal field strength and decreases with solids content and feed flow rate. Work is now in progress to evaluate the performance of a vacuum filter for coagula recovery.

Phase 1 of this program started in March 1976 and included the design, construction, and initial operation of the PDU. On June 25, 1980, Phase 2 of the program was initiated. It covers a 1-year operations program utilizing the existing PDU and is planned to include five runs with a targeted total operating time of 9 weeks. During this report period, Run 6, the initial run of the Phase 2 program was completed. The gasification system was operated for a total of 95 h at pressures up to 10 atm. Average product gas HHV values of 100 Btu/scf were recorded during 10-atm operation, while gasifying coal at a rate of 1100 lb/h. The run was terminated when the melt overflow system plugged after 60 continuous hours of overflow. Following this run, melt withdrawal system revisions were made, basically by changing the orifice materials from Monofrax to an 80 Cobalt-20 Chromium alloy. By the end of the report period, the PDU was being prepared for Run 7.

    The Office of Space and Defense Power Systems (OSDPS) of the Department of Energy (DOE) provides radioisotope Power Systems (BPS) for applications where conventional power systems are not feasible. For example, radioisotope thermoelectric generators were supplied by the DOE to the National Aeronautics and Space Administration for deep space missions including the Cassini Mission launched in October of .I 997 to study the planet Saturn. The Oak Ridge National Laboratory (ORNL) has been involved in developing materials and technology and producing components for the DOE for more than three decades. For the Cassini Mission, for example, ORNL was involved in the production of carbon-bonded carbon fiber (CBCF) insulator sets, iridium alloy blanks and foil, and clad vent sets (CVSs) and weld shields (WSs). This quarterly report has been divided into three sections to reflect program guidance from OSDPS for fiscal year (FY) 2000. The first section deals primarily with maintenance of the capability to produce flight quality carbon-bonded carbon fiber (CBCF) insulator sets, iridium alloy blanks and foil, clad vent sets (CVSs), and weld shields (WSs). In all three cases, production maintenance is assured by the manufacture of limited quantities of flight quality (FQ) components. The second section deals with several technology activities to improve the manufacturing processes, characterize materials, or to develop technologies for two new RPS. The last section is dedicated to studies of the potential for the production of 238Pu at OBNL.

The objective of this research is to develop information to be used by private industry and government agencies for planning waste disposal practices associated with advanced coal processes. To accomplish this objective, DOE has contracted Radian Corporation and the North Dakota Energy & Mineral Research Center (EMRC) to design, construct and monitor a limited number of field disposal tests with advanced coal process wastes. These field tests will be monitored over a three year period with the emphasis on collecting data on the field disposal of these wastes. The specific objectives for the reporting period were as follows: review fourth site candidates; obtain site access for the Freeman United site; select an ash supplier for the Illinois site and initiate subcontracts for on-site work; commence construction of the Freeman United test cell; and obtain waste for the Colorado Ute test site. Accomplishments under each task are discussed.

    During this quarter, the CW (continuous wave) and pulsed EPR (electron paramagnetic resonance) have been examined of the swelled Argonne Premium whole coals and the swelled residues of these coals. The CW EPR spectra will not be of high quality due to the unexpectedly microwave-lossy character of the pyridine used for swelling. Being relatively unaffected by this characteristic, the pulsed EPR measurements of the spin relaxation times of the broad (non-inertinite) and narrow (inertinite) macerals have been completed. Although detailed analyses of these results have not yet been done, marked differences have been found between the relaxation times of the swelled and unswelled coals and residues. The most startling are the less than 200 nsec times T{sub 1} of the spin-lattice relaxation of the inertinite radicals in the swelled samples. The T{sub 1} of this maceral in the unswelled coal were approaching 1 millisecond. The T{sub 1} contrast was much less pronounced between the swelled and non-swelled non-inertinite macerals. The prospects of significant progress in coal pore size measurements with xenon and NMR (nuclear magnetic resonance) have dimmed since the beginning of this project. This assessment is based on the dearth of these types of studies, a paper at a contractors` meeting on this subject that did not materialize, and discussions with colleagues with experience with the technique in coals. Instead, the authors have been developing a pulsed EPR technique for the spin probing of molecular motion to be applied to pores in carbonaceous materials. This report contains a copy of a nearly final draft of a paper being prepared on the development of this technique, entitled {open_quotes}Physical Characterization of the State of Motion of the Phenalenyl Spin Probe in Cation-Exchanged Faujasite Zeolite Supercages with Pulsed EPR.{close_quotes}

    This is the first in a series of quarterly reports describing the activities performed under Task 1. The analyses of Hot Gas Stream Cleanup (HGCU) ashes and descriptions of filter performance presented in this report were designed to address the problems with filter operation that are apparently linked to the characteristics of the collected ash. This task is designed to generate a data base of the key characteristics of ashes collected from operating advanced particle filters (APF`s) and to relate these ash properties to the operation and performance of these filters and their components. Observations of the filter assembly during site visits to the Tidd Demonstration Plant APF have led to the conclusion that that tenacious ash deposits that form in the APF apparently induce stresses that result in bent and/or broken ceramic candle filter elements. A site visit, was made to the Tidd APF on October 27, 1994 to collect ash samples from various locations in the filter vessel and to document the condition of the APF. A variety of laboratory analyses were performed on ash samples collected during this site visit to assess whether recent attempts to introduce larger particles into the ash deposits by derating the cyclone upstream of the APF have been successful. Some particles larger than 45 Jim were identified in various ash samples from the APF, but they account for less than 5 % of the mass of the ash. Although Scanning Electron Microscope EDX spectra and elemental maps lack the resolution to identify the bonds between particles in the ash agglomerates found in the APF, an excellent stereographic image of the structure of an ash nodule collected from the APF was generated with the Scanning Electron Microscope. The stereographic image was very enlightening as to the structure of the nodule.

    The existence of free electrons in coals` natural site offers a great attraction for Electron Paramagnetic Resonance (EPR) analysis to aid in the study of the structure and composition of coal. This direct and non-destructive approach to coal analysis has been hindered by the problem of resolution using the conventional 9.5 GHz EPR spectrometers. In the past few years, we have developed techniques including W-band Very High Frequency EPR spectroscopy as a means of determining the quantity and structure of organic sulfur in native and desulfurized coals. The state of the art 95 GHz (W-band) EPR spectrometer which we have constructed shows a well resolved spectrum including the interaction between unpaired electrons and the heteroatom like sulfur. The spectra also provide quantitative as well as qualitative information regarding different sulfur species. In collaboration with researchers at the University of Kentucky, we are also analyzing the result of desulfurization techniques on the presence of various sulfur species in coal. In the past, we have tried to synthesize various model compounds comparing their W-band spectra with other models, the predictions of theoretical models, and with the W-band spectra of coal specimens. In this quarter, we have been concentrating our efforts on developing a new standard protocol in handling and preparing the coal samples for EPR measurements to provide a quantitative comparison between the EPR spectra of coal in the natural state and desulfurized. Ten coal samples, both native and desulfurized, have been provided to us. These samples have been run in both laboratories. The simulation of coal EPR spectra has been carried out using several mathematical models. EPR results now are being compared with XANES data.

    Two long gasification tests were accomplished (66 and 72 hours of slagging operation) this quarter, and the balance of the wastewater needed for the second cooling tower (CT) test (approx. 11,000 gallons) was generated. Eleven thousand gallons of slagging fixed-bed gasifier (SFBG) wastewater were solvent extracted and ammonia stripped (AS) to nominal levels of 160 mg/1 phenol and 600 mg/1 NH/sub 3/. This wastewater is being further treated by activated sludge (AS) and granular activated carbon (GAC) processing to prepare a high quality makeup for the second CT test. Phenol mass balances indicated that > 90 pct of the phenol was stripped from the tower, indicating that previous assumptions of high levels of biodegradation were erroneous. Over 80 pct of the ammonia and about 25 pct of the methanol were also stripped. Data collected during steady state operation of the bench-scale rotating biological contractor indicate complete removal of phenolics and alcohols, and 94 pct removal of BOD. Nitrification also occurred in this unit, with over 30 pct removal of ammonia. Problems due to individual bacteria, present in the biotreated wastewater, passing through the multi-media filter and thus decreasing the carbon adsorption efficiency of the GAC system, have resulted in lower treatment rates than originally anticipated. As a result, to achieve the desired treatment, the contact time of the wastewater with the carbon in the granular activated carbon system has been increased. Since this has decreased the treatment rate, a larger carbon adsorption system has been designed and is presently being constructed.

    New furnaces were built based on fused silica with NiChrome heating elements custom-wound on alumina ceramic to self-compensate for induced magnetic fields during operation. During tests these furnaces failed due to thermal stresses caused by the high temperature cement used to hold the alumina ceramic in place. As a third solution pieces of boron nitride have been procured from which new furnace bodies will be machined during the third quarter. In order to increase the in-house capacity for machining ceramic parts a small lathe was ordered. The implementation of the LabView data acquisition software from National Instruments, Inc. took more time than anticipated and is still not completed. Major difficulties had to be overcome during the integration of the separate positive and negative high voltage supplies ({plus_minus}1000V). It became apparent that a custom-designed switch had to be installed to safeguard the data acquisition modules and the Apple Macintosh Quadra 700 computer again inadvertent exposure to the high voltages during switching operations. Martin Vasey, the software consultant, has made significant progress but the task is far from complete. Major time was spent on integrating the National Instruments GPIB Board with the Omega Temperature Controller via an the RS 232 port and to overcome compatibility problems. Because the Omega Temperature Controller failed catastrophically during tests completion of this task has been put on hold. To proceed with the work one of the PERKIN-ELMER Pt-wound furnaces which is available in the P.I.`s laboratory has been installed for the initial runs.

    The correlation and prediction of kinetic rates and mechanisms of the reactions of gas phase species with coal chars represent a difficulty undertaking under the best of circumstances. Solid phase heterogeneity and impurities, complex pore structure, transport limitation, and evolution of active surface represent just a few of the well known problems. Temperature programmed desorption (TPD) has become a standard technique for investigating the physics-chemical state of adsorbed species on surfaces. The predecessor of TPD-type methods was the flash filament technique, whereby gases adsorbed on wire filaments are rapidly desorbed upon rapid heating in an ultrahigh vacuum. This technique was subsequently adapted to catalytic surfaces. Experimental methods and interpretation of TPD spectra for well defined crystalline surfaces have been well established. However, corresponding techniques for polycrystalline, amorphous, and heterogeneous materials are not as well developed. TPD spectra usually consist of one or more peaks. The shapes of the peaks and the position of the peak maxima with respect to temperature are related in a fundamental manner to the desorption process, and, therefore, provide basic information regarding the energetics of the desorbed species. The current project is directed at developing related techniques for the characterization and prediction/correlation of the reactivity of ``young`` chars to steam and oxygen. Of particular interest is mapping of the reactivity behavior of the resultant chars, as revealed by the energetic heterogeneity of the complexes with char preparation conditions; i.e., heating rate and ultimate temperature. In this quarterly report, TPD results on two CO{sub 2}-gasified chars are summarized.

    The investigation of methods for the production and testing of iron-pillared clay catalysts was continued in this quarter. The surface area of the mixed alumina/iron pillared clay catalyst decreased to 51 m{sup 2}/g on sulfidation. Thus the stability of the alumina pillars during the sulfidation and thermal treatments prevented the total collapse that occurred in the case of the iron-pillared clays. Previously the mixed alumina/iron pillared clays were tested for hydrocracking activities with bibenzyl. This testing was extended to a determination of activity with a second model compound substrate (pyrene), representative of the polynuclear aromatic systems present in coal. Testing of the mixed alumina/iron-pillared catalysts with 1-methylnaphthalene gave interesting results that demonstrate shape selectivity. The clay-supported iron hydroxyoxide catalysts prepared by impregnation of iron species on acidic clays were further investigated. Sulfidation of these catalysts using the carbon disulfide in situ method gave hydrocracking activities with bibenzyl that were somewhat less than those obtained by presulfidation with H{sub 2}/H{sub 2}S mixtures. Liquefaction of Wyodak subbituminous coal was very successful with the iron impregnated clay catalyst, giving a highly soluble product. High conversions were also obtained with the mixed alumina/iron-pillared clay catalyst, but the yield of oil-solubles was considerably lower. Several new catalysts were synthesized with the idea of decreasing the pillar density and thereby increasing the micropore volume. These catalysts were prepared by first pillaring with an organic ammonium pillaring agent, then introducing a lower number of silica or alumina pillars. Finally the iron component was added either before or after thermal removal of organic pillars.

    In this research project we plan to determine the rate of oxidation of pyrite associated with coaly particles (coal slurry solid) when the pH of the surrounding environment is held at approximately 7.8. Coaly particles that contain pyrite are generated during the preparation of Illinois Basin coal for market. These particles are discharged to an impoundment, which eventually must be reclaimed. The purpose for reclamation is either to prevent the generation of acidic solution as the pyrite in the coal slurry solid reacts with air, or to prevent the migration of the acidic solution to a groundwater aquifer. The reclamation is usually accomplished by covering the impoundment with a four-foot-thick layer of topsoil. One possible alternative method for reclamation of a coal slurry impoundment is to mix in alkaline residue from the fluidized-bed combustion of coal. This codisposal would slow the production of acid and would also neutralize any acid produced. If the codisposal method is found to be environmentally acceptable, it will save the coal mining companies part of their cost of reclamation, and also provide a safe and useful disposal outlet for a portion of the residue that is generated by the fluidized-bed combustion of coal. During this quarter we purchased and set up two automatic titrators, which will be used in determining the rate of pyrite oxidation at nearly neutral pH. The titrators will provide a means for maintaining the pH at the desired level. The rate at which sulfate ion is produced as a result of pyrite oxidation will be used to measure the amount of pyrite oxidized over time.

    This advanced combustion system research program is for the development of innovative coal-fired process heaters which can be used for high temperature melting, smelting and waste vitrification processes. The process heater systems to be developed have multiple use applications; however, the Phase 3 research effort is being focused on the development of a process heater system to be used for producing value added vitrified glass products from boiler/incinerator ashes and industrial wastes. The primary objective of the Phase 3 project is to develop and integrate all the system components, from fuel through total system controls, and then test the complete system in order to evaluate its potential marketability. During the past quarter, the major effort was completing some of the system modification installation designs, completing industry funded testing, developing a surrogate TSCA ash composition, and completing the TSCA ash Test Plan. The installation designs will be used for the equipment modifications planned for the end of CY 93. The industry funded testing consisted of vitrifying Spent Aluminum Potliner (SPL) which is a listed hazardous waste. This testing has verified that SPL can be vitrified into a safe, recyclable glass product. Some results from this testing are provided in Section 2.2.1. The surrogate TSCA ash composition was developed with input from various DOE laboratories and subcontractors. The surrogate ash consists of a mixture of MSW fly ash and bottom ash spiked with heavy metal contaminants. The levels of metal additives are sufficient to ascertain the partitioning of the contaminants between the glass and effluent flow streams. Details of the surrogate composition and the planned testing is provided in Section 4.2.2.

    To develop a new class of permselective inorganic membranes, the authors have identified electroless plating as a potential route to deposit a thin metal film on a porous substrate. Electroless plating is a controlled autocatalytic deposition of continuous film on the surface of a substrate by the interactions of a metal salt and a chemical reducing agent. This method can give thin films of metals, alloys and composites on both conducting and nonconducting surfaces. The objective of this project is to develop thin film palladium membranes for separation of hydrogen in high temperature applications. The authors plan to use electroless plating to deposit thin palladium films on microporous ceramic and silver substrates. They plan to characterize the membrane in terms of permeability and selectivity for gas separation. To accomplish the research objective, the project requires three tasks: (1) development of a process for composite membrane formation; (2) characterization of fabricated composite membrane; and (3) development of theoretical model for hydrogen gas separation. During this quarter they extended their single-staged complete-mixing and cross-flow models to design a Two-Unit-Series (TUS), a Two-Stage Counter-Current Recycle Membrane Cascade (CRMC) and a Five-Stage CRMC arrangement. These designs have been used to study the performance of membrane modules for the separation of hydrogen through Palladium-ceramic composite membranes. The results show that for high-selective membrane, the effect of flow arrangement is of no consequence. Multi-staged cascading significantly improve the product purity and product separation.

    Oxidation of fresh surfaces of coal- and mineral-pyrite has been studied using electrochemical and photoelectrochemical techniques. This work was undertaken to better understand the oxidation processes that cause self-induced flotation of pyrite. Fresh surfaces were created by fracturing pyrite in situ, i.e., in solution. Chronoamperometry was used to determine the potential at which a newly created surface does not show oxidation or reduction currents. The ``stable`` potentials for pyrite are {minus}0.28 V (SHE) at pH 9.2 and 0 V at pH 4.6. Subsequent cyclic voltammograms show the incipient oxidation mechanism that involves the formation of sulfur products, which are believed to be hydrophobic. It is shown that the lower flotation edge of pyrite coincides with its incipient oxidation potential. The photocurrent generated at fractured pyrite surfaces by chopped illumination was used to determine the semiconducting characteristics of the electrodes. The results indicate that a spontaneous depletion layer is formed on the fresh surfaces of n-type pyrite. The depletion layer is attributed to an intrinsic, acceptor-like surface state. Charge storage in this surface state pins the band edges over a wide potential range, accounting for the metallic-like electrochemical behavior that has been reported for pyrite. The existence of an intrinsic surface state is consistent with XPS studies on pyrite surfaces prepared in vacuum, which reveal an FeS-like species in the surface region. During this report period, all of the data previously obtained has been analyzed in an attempt to better understand the mechanism of pyrite flotation with respect to its oxidation. The results of this analysis are included in this quarterly report. In addition, samples of pyrite from seven different sources were obtained. In situ fracture, photoelectrochemical and cyclic voltammetry studies have been conducted on electrodes made from these pyrites.

    The major objectives of this work are (1) to determine the Eh-pH conditions under which pyrite is stable, (2) to determine the mechanism of the initial stages of pyrite oxidation, and (3) to determine if the semi-conducting properties of pyrite effects its oxidation behavior. It is known that moderate oxidation of pyrite produces a hydrophobic surface product. This hydrophobic product makes it extremely difficult to depress pyrite in coal flotation circuits. The eventual objective of this work is to prevent pyrite oxidation in order to better depress pyrite in coal flotation circuits. It has been shown that by holding the potential of pyrite at its stable potential during fracture, pyrite undergoes neither oxidation nor reduction. It has also been found that fresh pyrite surfaces created by fracture in an electrochemical begin to oxidize at potentials that are about 200 mV more negative than the potentials reported in the literature for pyrite oxidation. This report period, electrochemical impedance spectroscopy (EIS) studies were continued. As discussed in the seventh quarterly progress report, the impedance of pyrite does not show the characteristics expected for either semi-conducting or metallic electrodes. Additional studies were conducted to confirm the anomalous impedance behavior. For this purpose, freshly fractured surfaces were progressively polished on 600 and 1,200 grit silicon carbide paper, and with 0.3 {micro} {alpha}-alumina and 0.05 {micro} {gamma}-alumina micropolish. Polishing is known to introduce defects in the lattice structure of semi-conducting electrodes and it was anticipated that the defects would effect the interfacial capacitance.

    A multistep direct liquefaction process specifically aimed at low-rank coals (LRCs) has been developed at the Energy & Environmental Research Center (EERC). The process consists of a preconversion treatment to prepare the coal for solubilization, solubilization of the coal in the solvent, and polishing using a phenolic solvent or solvent blend to complete solubilization of the remaining material. The product of these three steps can then be upgraded during a traditional hydrogenation step. This project addresses two research questions necessary for the further development and scaleup of this process: (1) determination of the recyclability of the solvent used during solubilization and (2) determination of the minimum severity required for effective hydrotreatment of the liquid product. The project is being performed as two tasks, the first consisting of ten recycle tests and the second consisting of twelve hydrotreatment tests performed at various conditions. Several activities were performed during this quarter. (1) A paper entitled {open_quotes}Solvent Recyclability in a Multistep Direct Liquefaction Process{close_quotes} was presented at the 1995 Coal Liquefaction and Gas Conversion Contractors{close_quote} Review Conference that was held in Pittsburgh, PA, August 29-31, 1995. (2) The Task 1 solvent recyclability tests were completed. (3) The Task 1 quality assurance/quality control checks were performed. (4) The first seven Task 2 hydrotreatability tests were completed. Analysis of the Task 1 data indicates that (1) the multistep process produces adequate quantities of excess solvent for recycle and (2) the product slates of all of the tests were fairly consistent.

    An investigation of new methods for the production of iron-pillared clay catalysts and clay-supported iron hydroxyoxide catalysts and the determination of their catalytic activities was continued in this quarter. Previous work in this project showed that a catalyst prepared by adding ferric nitrate and ammonia to an acid-washed clay gave an active catalyst following sulfidation. Further testing of this catalyst with a model compound showed that its hydrocracking activity was considerably lower when used in 10% concentration rather than 50%. In contrast, the mixed iron/alumina pillared clay catalysts were still highly effective at 10% concentration and gave good conversions at one and two hour reaction times. An investigation of preparation methods demonstrated that calcination of both the iron hydroxyoxide-impregnated clay and the mixed iron/alumina pillared clays is essential for activity. High activity was obtained for these catalysts only when they were removed from the aqueous media rapidly, dried, and calcined. The use of ferric sulfate to prepare a clay-supported sulfated iron catalyst was attempted, the resulting catalyst was relatively inactive for hydrocracking. Several new catalysts were synthesized with the idea of decreasing the pillar density and thereby increasing the micropore volume. A zirconia-pillared clay with low pillar density was prepared and intercalated with triiron complex. The hydrocracking activity of this catalyst was somewhat lower than that of the mixed alumina/iron-pillared catalyst. Other new catalysts, that were prepared by first pillaring with an organic ammonium pillaring agent, then introducing a lower number of silica or alumina pillars, and finally the iron component, were also tested. The mixed alumina/iron-pillared catalysts was further tested at low concentration for pyrene hydrogenating and hydrocracking activities.

    An investigation of new methods for the production of mixed pillared clay catalysts and clay-supported catalysts and determination of their catalytic activities were continued in this quarter. To demonstrate the reproducibility of the preparative method for high activity iron/alumina-pillared montmorillonite catalysts, a new batch of the catalyst was prepared and tested for hydrocracking activity with bibenzyl. This preparation gave conversion and product distribution similar to that reported previously. The mixed iron/alumina-pillared clay was also prepared using a pillaring solution that was aged for longer period of time. To determine the importance of the type of pillaring support in hydrocracking activity, iron/zirconia-pillared montmorillonite was prepared using the same technique as that for iron/alumina-pillared montmorillonite. The reaction of bibenzyl with the sulfided iron/zirconia-pillared catalyst gave a lower hydrocracking conversion than the iron/alumina-pillared catalyst. Addition of a second catalytic metal to the clay support was attempted to determine if a synergistic effect could improve liquefaction. Ferric nitrate and stannous chloride were added to the clay, but the resulting catalyst was relatively poor for hydrocracking and hydrogenation compared with ferric nitrate supported on the clay. New disposable iron catalysts with high acidity and surface area are desired for coal liquefaction. Synthetic iron aluminosilicates were prepared by methods similar to those used for the nickel-substituted synthetic mica montmorillonite (NiSMM) catalysts, which are very effective for hydrogenation and reforming of hydrocarbons. The iron aluminosilicate catalysts were tested for hydrocracking and hydrogenation of bibenzyl, naphthalene and pyrene. Pyrene hydrogenation was effectively catalyzed by the sulfided synthetic iron catalyst.

The chemical composition was measured by ICP atomic emission spectrometry. The structural changes in the clay as well as the iron oxide particle sizes were characterized by X-ray diffraction techniques. Task 2: The Selective Catalytic Reduction (SCR, i.e., NO reduction with NH{sub 3}) activities of the delaminated pillared clay were tested and compared with four other most active SCR catalysts: a commercial V{sub 2}O{sub 5} + WO{sub 3}/TiO{sub 2} catalyst, a Fe{sub 2}O{sub 3}-pillared clay, and two supported Fe{sub 2}O{sub 3} catalysts (on Al{sub 2}O{sub 3} and TiO{sub 2}). The delaminated Fe{sub 2}O{sub 3} pillared clay exhibited the highest SCR activities. Catalyst stability test showed that the delaminated sample was also stable. Task 3: To further increase the SCR activity of the delaminated pillared clay, Cr{sub 2}O{sub 3} was doped as a promoter by incipient wetness. Task 4: Deactivation effects of SO{sub 2} and H{sub 2}O on the SCR activities of the delaminated Fe{sub 2}O{sub 3} pillared clay were studied, and compared with other SCR catalysts.

    The ultimate objective of this research is to uncover new catalytic processes for the liquefaction of coal and for upgrading coal-derived fuels by removing undesirable organosulfur, organonitrogen and organooxygen constituents. Basic to both the liquefaction of coal and the purification of coal liquids is the transfer of hydrogen from such sources as dihydrogen, metal hydrides or partially reduced aromatic hydrocarbons to the extensive aromatic rings in coal itself or to aromatic sulfides, amines and ethers. Accordingly, this study is exploring how such crucial hydrogen-transfer processes might be catalyzed by soluble, low-valent transition metal complexes under moderate conditions of temperature and pressure. During the fifth quarter of this three-year grant the following phases of this study received particular attention: (a) the principal investigator completed his three-month period as visiting scientist at Cornell University, October 1 to December 31, 1985, with Professor Roald Hoffmann on the topic of Extended Hueckel Molecular Orbital calculations of organometallic structure; (b) final gas evolution studies between LiAlH/sub 4/ and bipyridyl(1,5-cyclooctadiene) nickel have been made and the related manuscript written for publication; (c) gas evolution studies between diisobutylaluminum hydride and phosphine complexes of Pt(0) and Ni(0) have been undertaken, as part of our trying to understand how powerful reducing agents can be generated from such combinations; (d) hydrogen shuttling studies continue between dihydroaromatic hydrocarbons and Ni(0) complexes; (e) studies on the cleavage of benzylic C-C bonds by Ni(0) and Cr(0) complexes are being intensified; and (f) attempts are being made to isolate crystalline samples of several organonickel intermediates in the foregoing cleavage reactions, so that x-ray structure determinations can be carried out.

    A novel technique for selectively coagulating and separating coal from dispersed mineral matter has been developed at Virginia Tech. The process, known as Selective Hydrophobic Coagulation (SHC), has been studied under the sponsorship of the U.S. Department of Energy since 1986 (Contracts DE-AC22-86PC91221 & DE-AC22- 9OPC90174). The SHC process differs from oil agglomeration, shear flocculation, polymer flocculation, and electrolytic coagulation processes in that it does not require reagents or additives to induce the formation of coagula. Often, simple pH control is all that is required to (i) induce the coagulation of coal particles, and (ii) effectively disperse particles of mineral matter. When the coal is superficially oxidized, a small dosage of reagents may be used to promote coagulation. During the past quarter, stability calculations were carried out to develop a better understanding of the selective coagulation of fine coal and associated mineral matter. The calculations were performed for interactions involving coal, silica and clay particles. The analyses suggest that the heterocoagulation of the edges of clay particles with coal particles controls the overall selectivity of the SHC process. In Subtask 3.3, froth flotation was explored as a possible technique for recovering hydrophobic coagula. Experimental test data obtained using this technique were analyzed using a statistical regression program. The analyses indicate that froth flotation can be used to successfully recover hydrophobic coagula provided that adequate precautions are taken to minimize coagula breakage due to turbulence. Recommendations include the use of low aeration rates and little or no additions of wash water.

The basic premise of this project is that vanadyl pyrophosphate (VPO), a catalyst used commercially in the selective oxidation of butane to maleic anhydride, can be developed as a catalyst for selective methane oxidation. Data supporting this idea include published reports indicating moderate to high selectivity in oxidation of ethane, propane, and pentane, as well as butane. Methane oxidation is a much more difficult reaction to catalyze than that of other alkanes and it is expected that considerable modification of vanadyl pyrophosphate will be required for this application. It is well known that VPO can be modified extensively with a large number of different promoters and in particular that promoters can enhance selectivity and lower the temperature required for butane conversion.

This was mainly attributed to the high pyritic sulfur content of the boiler fuel. A significant reduction in SO{sub 2} emissions could be accomplished by removing the pyrite from the coals by advanced physical fine coal cleaning.

When raw coal was fed, the extracted cakes contained 9-34% THF solubles. HTI also observed improved filtration during the periods that agglomerates were fed. Improved operability, if verified by additional work, could be an economically significant benefit of coal cleaning by oil agglomeration at low pH. An apparently higher Mo addition rate (see fourth bullet) may have contributed to the benefits of using oil-agglomerated coal. Other stream sample characteristics changed when oil-agglomerated coal was fed in Conditions 2-4, relative to when uncleaned coal was fed in Conditions 1 and 5. The ash content of the 0-6 bottoms samples was lower when oil-agglomerates were fed. The THF-soluble 524{degrees}C+ resid concentration in the feed slurry doubled when agglomerated coal was fed. Three factors may have influenced these characteristics. Higher coal conversion would have produced more resid. More efficient toluene-extraction of the filter cake would have recycled more resid. Removal of distillate as product to offset oil fed as part of the agglomerated coal would preferentially recycle the heaviest components.

    PETC has implemented a number of advanced combustion research projects that will lead to the establishment of a broad, commercially acceptable engineering data base for the advancement of coal as the fuel of choice for boilers, furnaces, and process heaters. Vortec Corporation`s Phase III development contract DE-AC22-91PC91161 for a {open_quotes}Coal-Fired Combustion System for Industrial Process Heating Applications{close_quotes} is a project funded under the DOE/PETC advanced combustion program. This advanced combustion system research program is for the development of innovative coal-fired process heaters which can be used for high temperature melting, smelting and waste vitrification processes. The process heater systems to be developed have multiple use applications; however, the Phase III research effort is being focused on the development of a process heater system to be used for producing value added vitrified glass products from boiler/incinerator ashes and industrial wastes. The primary objective of the Phase III project is to develop and integrate all the system components, from fuel through total system controls, and then test the complete system in order to evaluate its potential marketability. During the past quarter, the major effort was concentrated on conducting the 100 hour demonstration test. The test was successfully conducted from September 12th through the 16th. The test program consisted of one test run, with a duration of 100 hours at a nominal feed rate of 1000 lbs/hr. Throughout the test, the CMS was fired with coal and a coal by-product (i.e. coal-fired boiler flyash) as the primary fuels. Natural gas was used as an auxiliary fuel as necessary to provide process trim. The feedstock consisted of a coal-fired utility boiler flyash and dolomite and produced a stable, fully-reacted vitrified product. The fly ash, supplied by PENELEC, contained between 6 and 12% by weight of carbon because of the low NO{sub x} burners on the PENELEC boilers.

    This project`s goal is the development of a commercially viable, cobalt-based Fischer-Tropsch (F-T) catalyst for use in a slurry bubble column (SBC) reactor. During the seventh quarter, significant progress in several areas has enabled us to make a number of important conclusions. Preliminary catalyst preparation of 3 batches of a Ru-promoted 20% Co/Al{sub 2}O{sub 3} has confirmed the similarity in catalysts prepared by Energy International and by Calsicat using the same procedure. This similarity was evident in both fixed and SBC reactor studies. All TiO{sub 2}-supported Co catalysts have been found to have poor F-T properties in both the fixed-bed and SBC reactors. These catalysts had been prepared following exactly the procedures given in the Exxon patents. One of the main problems in using TiO{sub 2} as a support is the fact that it has low surface area for supporting a 20 wt % Co catalyst. Another problem is that it does not seem to be robust enough for use in a SBC reactor. Ru promotion of Co/SiO{sub 2} does not have as dramatic an effect on catalyst activity as seen for Co/Al{sub 2}O{sub 3}. However, it does play a major role in maintaining higher activity (factor of 2 in the SBCR) when K is added to Co/Sr/SiO{sub 2}. Zr has been clearly shown by us to significantly enhance the F-T activity of Co/SiO{sub 2}. Such promotion is a basis for many of the Shell cobalt F-T patents. Latest results indicate that Zr also improves the activity of Co/Al{sub 2}O{sub 3}, although the methane selectivity is also slightly elevated. Finally, for our design of a ``benchmark`` Co F- T catalyst, research has now shown using both fixed-bed and SBC reactors that 0.3 wt % K is the optimum amount to use with Ru- promoted 20 wt % Co/Al{sub 2}O{sub 3}. This amount of K greatly improves higher hydrocarbon selectivity without causing an unacceptable loss of activity.

    In the 2nd quarterly report, we discussed the lime/limestone process which precipitates N-S containing compounds by adding lime/limestone in a narrow pH range, and which can be an alternative to the K{sub 2}SO{sub 4} process. In this report, we focused on investigations of the lime/limestone process. First, we established an overall flow diagram for the lime/limestone process. Based on the diagram, we performed preliminary experimental investigations to outline practical process conditions. Out major investigations concerned about effects of pH on precipitation of the N-S compounds and precipitation characteristics of N-S compounds in a continuous crystallization system. We also performed an experimental investigation to study crystallization characteristic of the ammonium sulfate in the hydrolysis liquor. In studying effects of pH, we performed batch precipitation of the N-S compounds in a broad range of pH and investigated the effects of pH on the amount of required lime, the amount of the precipitate, and the fraction of N-S compounds precipitated. The result revealed the optimum range for precipitation of N-S compounds to be pH = 7.6--8.6. In studying continuous crystallization characteristics of the N-S compounds, a bench scale 4-liter continuous crystallization system was built to compare a typical Mixed-Suspension-Mixed-Product-Removal (MSMPR) crystallizer and Double-Draw-Off (DDO) crystallizer. In a preliminary test, the DDO was shown to be superior by increasing the average size of the precipitated crystals of N-S compounds from 97 {mu}m to 142 {mu}m and thus enhancing the filterability. In order to obtain information for a practical design of the lime/limestone process, we also set up a material balance for a 300 MWe power plant facility. A preliminary calculation showed that a process on the scale could produce approximately 56 tons ammonium sulfate fertilizer per day.

    The major technical objectives of this program are threefold: (1) to develop the design tools and a fundamental understanding of the fluid dynamics of a slurry bubble column reactor to maximize reactor productivity, (2) to develop the mathematical reactor design models and gain an understanding of the hydrodynamic fundamentals under industrially relevant process conditions, and (3) to develop an understanding of the hydrodynamics and their interaction with the chemistries occurring in the bubble column reactor. Successful completion of these objectives will permit more efficient usage of the reactor column and tighter design criteria, increase overall reactor efficiency, and ensure a design that leads to stable reactor behavior when scaling up to large diameter reactors.

    1995-03-08

    The objective of this project is to develop high yield syntheses of oxygenate products that are liquid at room temperature using as starting materials dimethy ether (DME) or methanol. The identified products include: Dimethyl Carbonate (DMC), 1,1-Dimethoxyethane (DMOE), C{sub 2}{sup +} Alcohols/Ethers (C{sub 2}AE). The technical strategy is outlined below: (A) Synthesis of DMC via oxidative carbonylation of DME instead of methanol. Since this synthesis would not co-produce water as a byproduct, there is a potential for very high DME conversions in contrast to the low (ca 20%) conversions obtained in conventional plants. Technical emphasis will be placed on development of a supported copper catalyst with a capability for cleavage of DME into its chemisorbed organic moieties. (B) Synthesis of 1,1-dimethoxymethane (DMOE) from acetylene/CO/H{sub 2} process streams obtained from commercial methane oxidative pyrolysis processes. In the overall processing scheme the syngas would be converted to DME. The wet acetylene stream would be partially condensed to retain an equivalent of water and then condensed with DME to produce EMOE. (C) Direct conversion of DME or DME/methanol to ethanol/propanol or their methyl ethers. Under the influence of functionalized alcohol condensation catalysts developed exclusively at Amoco it should be possible to achieve direct conversion of dimethyl ether (or methanol) to ethanol/propanol and/or the methyl ethers of these alcohols. Although this reaction is not currently known, a combination of key catalyst components from identified systems should result in a DME conversion catalyst to C{sub 2}+ oxygenates. (D) Reaction of DME or acetylene with synthesis gas (CO/H{sub 2}) or methanol. A variety of catalysts will be tested for conversion of acetylene/CO/H{sub 2} or acetylene/methanol to propylene and conversion of DME/CO/H{sub 2} or DME/methanol to dimenthyoxymethane (DMM) and/or other oxygenates.

    The driving force for the granular flow in the experimental region is gravity. The vehicle which re-circulates this flow is an 46 cm Corra-Trough belt conveyor manufactured by Buck-El, Inc. A drawing of this conveyor is shown in Figure 3. Entrance and exit chambers were designed to route the flow between the chute and the conveyor. Both devices had to be flexible because the position of the chute relative to the conveyor changes each time the angle of the chute is changed. Finally, to control the entering flow more accurately, an adjustable gate apparatus was constructed. The first step in setting up the chute is angle adjustment. The granular material used in the experiments described in this report are technical quality glass spheres, three millimeters in diameter. These beads are produced by Cataphote, Inc. Cataphote lists the tolerances for the 3mm spheres at {plus_minus}0.2 mm. The average mass of a single bead was measured to be 0.034 g which gives an average measured specific gravity of the glass at 2.42 g/cm{sup 3}.

Some of the high points for this period are: the activity of the base catalyst prepared by pressure filtration of the Wilsonville Run 262E V-1082 ashy resid was determined and compared with the conversion of coal in the absence of any added catalyst; this material was found to contain 740 mg Mo/kg; in the catalyst screening test, the pressure filtered solids that had been added to the reaction mixture to a level equivalent to the solids contained in Wilsonville Run 263J gave coal conversion of 98.2% with a resid conversion of 24%; and the effect of presulfiding conditions on activating a Mo-impregnated coal with different H{sub 2}S/H{sub 2} mixtures at different temperatures and reaction times was investigated.

    There are currently about 910 million cubic yards of anthracite culm (mine refuse) contained in 800 separate banks in a 480 square mile area in the Wilkes-Barre (W-B) anthracite mining region. Although this material represents a significant fuel value, equivalent to approximately 1.25 billion barrels of fuel oil, the culm banks have accumulated because no satisfactory method of combusting this fuel was available until the relatively recent development of the atmospheric fluidized bed (AFB) steam generator. A program was initiated in October 1978 to design, construct and evaluate a 100,000 pph AFB steam generator burning anthracite culm with the addition of fresh anthracite, if required. The unit is to demonstrate the technical, economical and environmental feasibility of producing 150 psig saturated steam for district heating in downtown W-B. Phase I of the program consists of the design of the atmospheric fluidized bed (AFB) plant and a hot model test program. Phase II of the program consists of construction, operation, testing and evaluation of the boiler and boiler plant.

    The overall objective of this project is to develop a new approach for the direct liquefaction of coal to produce an all-distillate product slate at a sizable cost reduction over current technology. The approach integrates coal selection, pretreatment, coal swelling with catalyst impregnation, liquefaction, product recovery with characterization, alternate bottoms processing, and carrying out a technical assessment including an economic evaluation. The primary coal of this program, Black Thunder subbituminous coal, can be effectively beneficiated to about 4 wt% ash using aqueous sulfurous acid pretreatment. This treated coal can be further beneficiated to about 2 wt% ash using commercially available procedures. All three coals used in this study (Black Thunder, Burning Star bituminous, and Martin Lake lignite) are effectively swelled by a number of solvents. The most effective solvents are those having hetero-functionality. In addition, a synergistic effect has been demonstrated, in which solvent blends are more effective for coal swelling than the pure solvents alone. Therefore, it will be necessary to use only low levels of swelling agents and yet promote the impregnation of catalyst precursors. The rate of the impregnation of catalyst precursors into swollen coal increases greatly as the effectiveness of the solvent to swell the coal increases.

    The objective of this project is to determine the conditions for the hydrogen-heavy oil feed preparation so as to optimize the yield of hydrocracking reactions. Proper contacting of hydrogen with heavy oil on the catalytic bed is necessary to improve the yields of the hydrocracking reactions. It is most desirable to have the necessary amount of hydrogen available either in the dissolved or in entrained state, so that hydrogen diffusion to the reaction site does not provide rate controlling resistance to the overall rates of hydrocracking reactions. This project proposes to measure solubility and entrainment data for hydrogen in heavy oils at conditions such as in hydrocrackers, and investigate the improvement of these properties by usage of appropriate additives. Specifically, measurements will be carried out at temperatures up to 300{degrees}C and pressures up to 120 atmospheres. Correlations for solubility and entrainment kinetics will be developed from the measured data, and a method for estimating yield of hydrocracking reactions using these correlations will be suggested. Exxon Research and Engineering Company will serve as private sector collaborator providing A&T with test samples and some technical expertise that will assure successful completion of the project. Results are presented for solubility of hydrogen in hydrocarbons and in heavy petroleum fractions. Comparison with experimental data shows good agreements. It is also demonstrated that the model is easily applied to compute solubility of hydrogen in heavy petroleum fractions with fair degree of accuracy. Detailed results are presented.

    Coal-fueled gas turbines require the development of a number of new technologies which are being identified by METC and its Heat Engines Contractors. Three significant problems, that were Identified early in the development of coal-fueled engines, are the rapid wear of the turbine airfoils due to particulate erosion, the accumulation of deposits on portions of the airfoil surfaces due to slag deposition and the rapid corrosion of airfoils after the breakdown of surface coatings. The technology development study contained in this program is focused on improving the durability of the turbine through the development of erosion and deposition resistant airfoils and turbine operating conditions. The baseline turbine meanline design vas modified to prevent a local shock on the suction side of the rotor airfoil. New particle dimensionless parameters to be varied were determined. Three first-stage turbine meanline designs have been completed. The design of nev turbine airfoil shapes has been initiated. The calculation of particle trajectories has been completed for the baseline turbine vane and blade airfoils. The erosion model described in the previous technical report vas incorporated in the Post Processing Trajectory Analysis Code.

    Research at Virginia Tech led to the development of two complementary concepts for improving the removal of inorganic sulfur from many eastern US coals. These concepts are referred to as Electrochemically Enhanced Sulfur Rejection (EESR) and Polymer Enhanced Sulfur Rejection (PESR). The EESR process uses electrochemical techniques to suppress the formation of hydrophobic oxidation products believed to be responsible for the floatability of coal pyrite. The PESR process uses polymeric reagents that react with pyrite and convert floatable middlings, i.e., composite particles composed of pyrite with coal inclusions, into hydrophilic particles. These new pyritic-sulfur rejection processes do not require significant modifications to existing coal preparation facilities, thereby enhancing their adoptability by the coal industry. It is believed that these processes can be used simultaneously to maximize the rejection of both well-liberated pyrite and composite coal-pyrite particles. The technical research was initiated on October 1, 1992, and a detailed work plan and work schedule were developed. During this reporting period, research was conducted to evaluate the liberation characteristics of various pyrite samples, to determine the electrochemical reactions that influence the hydrophobicity of pyrite, and to examine the potential use of electrochemical methods for controlling the flotation and depression of pyrite.

    The goal of this project is to demonstrate the technical and economic feasibility of commercializing a biotechnology that uses plants to remediate soils, sediments, surface waters, and groundwaters contaminated by heavy metals and radionuclides. This technology, known as phytoremediation, is particularly suited to remediation of soils or water where low levels of contaminants are widespread. Project objectives are to provide an accurate estimate of the capability and rate of phytoremediation for removal of contaminants of concern from soils and groundwaters at Department of Energy (DOE) sites and to develop data suitable for engineering design and economic feasibility evaluations, including methods for destruction or final disposition of plants containing contaminants of concern. The bioremediation systems being evaluated could be less expensive than soil removal and treatment systems, given the areal extent and topography of sites under consideration and the investment of energy and money in soil-moving and -treating processes. In situ technology may receive regulatory acceptance more easily than ex situ treatments requiring excavation, processing, and replacement of surface soils. In addition, phytoremediation may be viable for cleanup of contaminated waters, either as the primary treatment or the final polishing stage, depending on the contaminant concentrations and process economics considerations.

This effect is also demonstrated by improved catalyst precursor impregnation with increased contact temperature. Laboratory- and bench-scale liquefaction experimentation is underway using swelled and catalyst impregnated coal samples. Higher coal conversions were observed for the SO{sub 2}-treated coal than the raw coal, regardless of catalyst type. Conversions of swelled coal were highest when Molyvan-L, molybdenum naphthenate, and nickel octoate, respectively, were added to the liquefaction solvent.

    The objective of this project is to demonstrate and evaluate commercially available Selective Catalytic Reduction (SCR) catalysts from U.S., Japanese, and European catalyst suppliers on a high-sulfur U.S. coal-fired boiler. SCR is a post-combustion nitrogen oxide (NOx) control technology that involves injecting ammonia into the flue gas generated from coal combustion in an electric utility boiler. The flue gas containing ammonia is then passed through a reactor that contains a specialized catalyst. In the presence of the catalyst, the ammonia reacts with NOx to convert it to nitrogen and water vapor. Although SCR is widely practiced in Japan and Europe on gas-, oil-, and low-sulfur coal-fired boilers, there are several technical uncertainties associated with applying SCR to U.S. coals. These uncertainties include: (1) potential catalyst deactivation due to poisoning by trace metal species present in U.S. coals that are not present in other fuels; (2) performance of the technology and effects on the balance-of-plant equipment in the presence of high amounts of SO{sub 2} and SO{sub 3}; and (3) performance of a wide variety of SCR catalyst compositions, geometries and methods of manufacture under typical high-sulfur coal-fired utility operating conditions. These uncertainties are being explored by constructing and operating a series of small-scale SCR reactors and simultaneously exposing different SCR catalysts to flue gas derived from the combustion of high sulfur U.S. coal. The demonstration is being performed at Gulf Power Company`s Plant Crist Unit No. 5 (75 MW capacity) near Pensacola, Florida. The project is funded by the U.S. Department of Energy (DOE), Southern Company Services, Inc. (SCS on behalf of the entire Southern electric system), the Electric Power Research Institute (EPRI), and Ontario Hydro. SCS is the participant responsible for managing all aspects of this project.

    The goal of this project is the development of a commercially-viable, cobalt-based Fischer-Tropsch (F-T) catalyst for use in a slurry bubble column reactor. The major objectives of this work are (1) to develop a cobalt-based F-T catalyst with low (< 5%) methane selectivity, (2) to develop a cobalt-based F-T catalyst with water-gas shift activity, and (3) to combine both these improvements into one catalyst. The project consists of five major tasks: catalyst development; catalyst testing; catalyst reproducibility tests; catalyst aging tests; and preliminary design and cost estimate for a demonstrate scale catalyst production facility. Technical accomplishments during this reporting period include the following. It appears that the higher activity obtained for the catalysts prepared using an organic solution and reduced directly without prior calcination was the result of higher dispersions obtained under such pretreatment. A Ru-promoted Co catalyst on alumina with 30% Co loading exhibited a 4-fold increase in dispersion and a 2-fold increase in activity in the fixed-bed reactor from that obtained with the non-promoted catalyst. Several reactor runs have again focused on pushing conversion to higher levels. The maximum conversion obtained has been 49.7% with 26g catalyst. Further investigations of the effect of reaction temperature on the performance of Co catalysts during F-T synthesis were started using a low activity catalyst and one of the most active catalysts. The three 1 kg catalyst batches prepared by Calsicat for the reproducibility and aging studies were tested in both the fixed-bed and slurry bubble column reactors under the standard reaction conditions. The effects of adding various promoters to some cobalt catalysts have also been addressed. Results are presented and discussed.

    Babcock and Wilcox (B and W) is conducting a five-year project aimed at the development of practical, cost-effective strategies for reducing the emissions of hazardous air pollutants (commonly called air toxics) from coal-fired electric utility plants. The need for air toxic emissions controls will likely arise as the US Environmental Protection Agency proceeds with implementation of Title III of the Clean Air Act Amendments of 1990. Data generated during the program will provide utilities with the technical and economic information necessary to reliably evaluate various air toxics emissions compliance options such as fuel switching, coal cleaning, and flue gas treatment. The development work is being carried out using B and W`s new Clean Environment Development Facility (CEDF) wherein air toxics emissions control strategies can be developed under controlled conditions, and with proven predictability to commercial systems. Tests conducted in the CEDF will provide high quality, repeatable, comparable data over a wide range of coal properties, operating conditions, and emissions control systems. The specific objectives of the project are to: (1) measure and understand the production and partitioning of air toxics species for a variety of steam coals, (2) optimize the air toxics removal performance of conventional flue gas cleanup systems (ESPs, baghouses, scrubbers), (3) develop advanced air toxics emissions control concepts, (4) develop and validate air toxics emissions measurement and monitoring techniques, and (5) establish a comprehensive, self-consistent air toxics data library. Development work is currently concentrated on the capture of mercury, fine particulate, and a variety of inorganic species such as the acid gases (hydrogen chloride, hydrogen fluoride, etc.).

    This report documents the fourth Sea-viewing Wide Field-of-view Sensor (SeaWiFS) Intercalibration Round-Robin Experiment (SIRREX-4), which was held at the National Institute of Standards and Technology (NIST) on 3-10 May 1995. The agenda for SIRREX-4 was established by a consensus reached at the conclusion of SIRREX-3: there should be an emphasis on training and work to foster and encourage uniform use of accepted protocols for calibrating radiometric instruments in the laboratory. The goal was to host the activity in a setting where proper techniques could be discussed and demonstrated. It seemed appealing to split the day between morning lectures and afternoon laboratory exercises or practicals. The former gave the user community a chance to present what was important to them and discuss it with acknowledged experts in radiometry, while the latter presented a unique opportunity for training and evaluation in the presence of these same experts. The five laboratory sessions were concerned with (1) determining the responsivity of a spectroradiometer and the spectral radiance of an unknown integrating sphere source, (2) demonstrating spectral field calibration procedures for an integrating sphere using three different instruments, (3) measuring spectral radiance using the plaque method, (4) setting up and aligning lamp calibration transfer standards using the NIST specifications for irradiance measurements, and (5) characterizing radiometric instruments. In addition to documenting some supplemental studies performed outside the laboratory sessions, this report includes an evaluation of the hardware that has been used during the SIRREX activities plus a critical evaluation of SIRREX objectives.

    This is the 9th quarterly technical progress report for the project entitled ``Pyrite surface characterization and control for advanced fine coal desulfurization technologies``, DE-FG22-90PC90295. The work presented in this report was performed from September 1, 1992 to November 31, 1992. The objective of the project is to conduct extensive fundamental studies on the surface chemistry of pyrite oxidation and flotation and to understand how the alteration of the coal-pyrite surface affects the efficiency of pyrite rejection in coal flotation. During this reporting period, the surface oxidation of pyrite in various electrolytes was investigated. It has been demonstrated, for the first time, that borate, a pH buffer and electrolyte used by many previous investigators in studying sulfide mineral oxidation, actively participates in the surface oxidation of pyrite. In borate solutions, the surface oxidation of pyrite is tronly enhanced. The anodic oxidation potential of pyrite is lowered by more than 0.4 volts. The initial reaction of the borate enhanced pyrite oxidation can be described by:FeS{sub 2} + B(OH){sub 4}{sup =} ------> [S{sub 2}Fe-B(OH){sub 4}]{sub surf} + e. This reaction is irreversible and is controlled by the mass-transfer of borate species from the solution to the surface. It has been shown that the above reaction inhibits the adsorption of xanthate on pyrite. Comparative studies have been made with other sulfide minerals. The solution chemistry of the iron-borate systems have been studied to understand the electrochemical results.

    An experimental plan outlining the first year`s activity was sent to Dr. Lori Gould, Project Officer/Contracting Officer`s Technical Representative on April 24, 1995. An approval was received with some questions on June 15, 1995. However, with some foresight of the director of the in-house combustion group of the PETC, Dr. Ekmann, a tentative hold-off on the purchase of the equipment was requested by the project officer on June 29, 1995. Enclosed with that request were some of Dr. Ekmann`s concerns. The research team spent the month of July in study of pertinent literature as well as in the preparation of the responses to Dr. Gould`s comments and Dr. Ekmann`s concerns. These responses included the choice of the reactor, reactor design, rate of gas heating, detailed test matrix and answers to host of other comments. Upon review of the above information submitted on July 24, 1995 by the Rust research team, the project officer called for a conference call on September 6, 1995 which involved the PI (Dr. Kumpaty), the research consultant (Mr. Subramanian), Dr. Gould and Dr. Ekmann. Dr. Ekmann insisted that further calculations be made on the rate of gas heating without taking radiation into account. Accordingly, calculations pertaining to the rate of gas heating based on convection were performed and submitted to Dr. Ekmann on September 13, 1995. This report contains the information emerged through the dialogue between the Rust College research team and the PETC represented by Dr. Gould and Dr. Ekmann during this quarter.

    This project is a major step in the Department of Energy`s program to show that ultra-clean coal-water slurry fuel (CWF) can be produced from selected coals and that this premium fuel will be a cost-effectve replacement for oil and natural gas now fueling some of the industrial and utility boilers in the United States as well as for advanced combustars currently under development. The replacement of oil and gas with CWF can only be realized if retrofit costs are kept to a minimum and retrofit boiler emissions meet national goals fbr clean air. These concerns establish the specifications for maximum ash and sulfur levels and combustion properties of the CWF. This cost-share contract is a 51-month program which started on September 30, 1992. This report discusses the technical progress, made during the 6th quarter of the project from January 1 to March 31, 1994. The project has three major objectives: (1) The primary objective is to develop the design base for prototype commercial advanced fine coal cleaning facilities capable of producing ultra-clean coals suitable for conversion to coal-water slurry fuel for premium fuel applications. The fine coal cleaning technologies are advanced column flotation and selective agglomeration. (2) A secondary objective is to develop the design base for near-term application of these advanced fine coal cleaning technologies in new or existing coal preparation plants for efficiently processing minus 28-mesh coal fines and converting this to marketable products in current market economics. (3) A third objective is to determine the removal of toxic trace elements from coal by advance column flotation and selective agglomeration technologies.
