    The removal of heteroatoms from naphtha using first row unsupported metal sulfide catalysts were completed. The maxima HDS activity, normalizing to the same weight of metal, is obtained for manganese sulfide while the minimum HDS activity is obtained for nickel sulfide. Chianelli et al. (1) reported that, for the first row transition metal sulfides, chromium sulfide has the highest activity for HDS of dibenzothiophene and manganese sulfide is the least active. The catalyst activity pattern of the first row transition metal sulfide for hydrodesulfurization of naphtha and dibenzothiophene is different. The maxima HDN activity, normalizing to the same weight of metal, is obtained for chromium sulfide and the minimum HDN activity is obtained for cobalt sulfide. The effect of substituents on the conversion of nitrogen compounds from the naphtha was also determined. The HDN conversion of alkyl-substituted pyridines and anilines are dominated by electronic effects rather than substituent effects. The effect of alkyl-substitution on the conversion of quinolines is relatively insignificant.

    The amount of individual nitrogen and sulfur presented in the feed and hydrotreated Illinois {number_sign}6 naphtha were determined. The major nitrogen class in the naphtha are anilines. The major sulfur components identified are thiophenes and benzothiophenes. The aniline and quinoline is harder to remove than pyridine. The aniline and pyridine, without any carbon substituted, is the easiest one to remove in their class. The quinoline, without any carbon substituted, is approximately as hard as one carbon substituted quinoline to remove. Both Co-Mo and Ni-W catalysts follow the similar pattern of the nitrogen removal at different temperatures. The sulfur compounds of the Ill. {number_sign}6 naphtha was separated to three classes, i.e. sulfides and thiols, thiophenes and benzothiophenes, for comparisons. The thiophenes was the major component of the hydrotreated naphtha at most temperatures; however, the sulfides and thiols class becomes the major component at temperatures greater than 300{degree}C.

    1984-07-01

    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.

    A method is described for upgrading a paraffinic naphtha including major amounts of C/sub 5/ and C/sub 6/ components to produce gasoline boiling range products of improved octane number, which comprises (i) hydrocracking the naphtha over a hydrocracking catalyst comprising zeolite beta and a hydrogenation-dehydrogenation component under conditions of elevated temperature and pressure and in the presence of hydrogen and at a conversion of not more than 25 volume percent to C/sub 5-/ products. This is done to effect a partial, preferential hydrocracking of the paraffins of relatively longer chain length in the naphtha and a concurrent isomerization of n-paraffins, to form a hydrocracking effluent comprising isobutane and higher boiling materials; (ii) fractionating the hydrocracked effluent to form (i) an isobutane stream, (ii) a relatively low boiling stream having a boiling range of approximately C/sub 5/ to 200/sup 0/F. and comprising C/sub 5/ to C/sub 7/ iso-paraffins, and (iii) a relatively higher boiling stream having an initial boiling point of approximately 200/sup 0/F., and (iii) reforming the relatively high boiling point stream to form a gasoline boiling range product of improved octane rating.

    1992-01-01

    The amount of individual nitrogen and sulfur presented in the feed and hydrotreated Illinois [number sign]6 naphtha were determined. The major nitrogen class in the naphtha are anilines. The major sulfur components identified are thiophenes and benzothiophenes. The aniline and quinoline is harder to remove than pyridine. The aniline and pyridine, without any carbon substituted, is the easiest one to remove in their class. The quinoline, without any carbon substituted, is approximately as hard as one carbon substituted quinoline to remove. Both Co-Mo and Ni-W catalysts follow the similar pattern of the nitrogen removal at different temperatures. The sulfur compounds of the Ill. [number sign]6 naphtha was separated to three classes, i.e. sulfides and thiols, thiophenes and benzothiophenes, for comparisons. The thiophenes was the major component of the hydrotreated naphtha at most temperatures; however, the sulfides and thiols class becomes the major component at temperatures greater than 300[degree]C.

  13. Coal liquefaction process with increased naphtha yields

    DOEpatents

    Ryan, Daniel F.

    1986-01-01

    An improved process for liquefying solid carbonaceous materials wherein the solid carbonaceous material is slurried with a suitable solvent and then subjected to liquefaction at elevated temperature and pressure to produce a normally gaseous product, a normally liquid product and a normally solid product. The normally liquid product is further separated into a naphtha boiling range product, a solvent boiling range product and a vacuum gas-oil boiling range product. At least a portion of the solvent boiling-range product and the vacuum gas-oil boiling range product are then combined and passed to a hydrotreater where the mixture is hydrotreated at relatively severe hydrotreating conditions and the liquid product from the hydrotreater then passed to a catalytic cracker. In the catalytic cracker, the hydrotreater effluent is converted partially to a naphtha boiling range product and to a solvent boiling range product. The naphtha boiling range product is added to the naphtha boiling range product from coal liquefaction to thereby significantly increase the production of naphtha boiling range materials. At least a portion of the solvent boiling range product, on the other hand, is separately hydrogenated and used as solvent for the liquefaction. Use of this material as at least a portion of the solvent significantly reduces the amount of saturated materials in said solvent.

One of the possibilities to achieve this increase of pool octane will be catalytic reforming of FCC naphtha. In this paper we evaluate the effects of FCC naphtha reforming on the reformer operation and gasoline pool volume for various lead phasedown scenarios. High-stability reforming catalysts, like TPR-8/CK-522 TRILOBE catalyst, will be required to maintain acceptable cycle lengths at the more severe reformer operating conditions. The properties and octane distribution of FCC naphtha are discussed, as well as its hydrotreating with high-active NiMo catalysts.

    Koslov, I.T.; Khavkin, V.A.; Nefedov, B.K.

    1986-03-01

    For the production of high-quality automotive gasolines, technology has been developed for a combined ''isoreforming'' process, in which hydrocracking of a heavy straight-run naphtha cut to give a high-octane component with an octane number of 84-86 (MM) is combined with catalytic reforming of the residual fraction from hydrocracking. The ''isoreforming'' technology can be used to produce AI-93 automotive gasolines with aromatic hydrocarbon contents of 45-49% by weight, without TEL, in yields of 78-82% by weight on the original feed. The authors also discuss a catalytic upgrading process for light straight-run naphtha distillates or raffinates from catalytic reforming. The influence of the depth of reaction in hydrocracking n-paraffins in the straight-run 62-105 degrees C cut on the yield of the C5-EP cut and its octane number is investigated.

  12. Ethanol versus naphtha under Brazil's economy

    SciTech Connect

    Luchi, N.R.

    1982-05-01

    Ethanol is able to replace naphtha in two of its major usages, as raw material for ethylene production and as fuel for Otto engines. This possibility raises the question of value - or opportunity cost - of ethanol. Ethanol's economic value as a fuel is that value which equals the cost of the fuel consumed by a given vehicle travelling a given distance. In each case, unblended gasoline, a gasoline and ethanol blend or hydrated alcohol alone are the alternative fuels used. Ethanol's economic value as feedstock for producing ethylene is defined as that which makes the revenue from the ethylene derived from alcohol equal to the total revenue of products resulting from thermal cracking of 1 m/sup 3/ of naphtha. In this paper it is shown that ethanol's highest value corresponds to its use as hydrated alcohol feedstock for ethylene production. However, present tax laws and subsidies favor ethanol fuel use. 4 refs.

    The acquisition and development of technical data are activities that provide the information base from which the Yucca mountain Site will be characterized and may P-ventually be licensed as a high-level waste repository. The Project Technical Data Base (TDB) is the repository for the regional and site-specific technical data required in intermediate and license application analyses and models. The TDB Quarterly Report provides the mechanism for identifying technical data currently available from the Project TDB. Due to the variety of scientific information generated by YMP activities, the Project TDB consists of three components, each designed to store specific types of data. The Site and Engineering Properties Data Base (SEPDB) maintains technical data best stored in a tabular format. The Geographic Nodal Information Study and Evaluation System (GENISES), which is the Geographic Information System (GIS) component of the Project TDB, maintains spatial or map-like data. The Geologic and Engineering Materials Bibliography of Chemical Species (GEMBOCHS) data base maintains thermodynamic/geochemical data needed to support geochemical reaction models involving the waste package and repository geochemical environment. Each of these data bases are addressed independently within the TDB Quarterly Report.

  14. Rate enhancement for catalytic upgrading coal naphthas

    The removal of heteroatoms from naphtha using first row unsupported metal sulfide catalysts were completed. The maxima HDS activity, normalizing to the same weight of metal, is obtained for manganese sulfide while the minimum HDS activity is obtained for nickel sulfide. Chianelli et al. (1) reported that, for the first row transition metal sulfides, chromium sulfide has the highest activity for HDS of dibenzothiophene and manganese sulfide is the least active. The catalyst activity pattern of the first row transition metal sulfide for hydrodesulfurization of naphtha and dibenzothiophene is different. The maxima HDN activity, normalizing to the same weight of metal, is obtained for chromium sulfide and the minimum HDN activity is obtained for cobalt sulfide. The effect of substituents on the conversion of nitrogen compounds from the naphtha was also determined. The HDN conversion of alkyl-substituted pyridines and anilines are dominated by electronic effects rather than substituent effects. The effect of alkyl-substitution on the conversion of quinolines is relatively insignificant.

    A naphtha catalytic reforming unit with four reactors in series is analyzed. A physical model is proposed to describe the catalytic reforming radial flow reactor. Kinetics and thermodynamics equations are selected to describe the naphtha catalytic reforming reactions characteristics based on idealizing the complex naphtha mixture by representing the paraffin, naphthene, and aromatic groups by single compounds. The simulation results based above models agree very well with actual operation unit data. PMID:15909350

    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.

    This is the fourth quarterly report describing the activities performed under Contract No. DE-AC21-94MC31160. Task 1 of this contract concerns analyses of HGCU ashes and descriptions of filter performance that are designed to address the problems with filter operation linked to the characteristics of the collected ash. Task 2 of this contract includes characterization of new and used filter elements. Some of the problems observed at the Tidd and Karhula PFBC facilities include excessive filtering pressure drop, the formation of large, tenacious ash deposits within the filter vessel, and bent or broken candle filter elements. These problems have been attributed to ash characteristics, durability of the ceramic filter elements, and specific limitations of the filter design. In addition to these problems related to the characteristics of PFBC ashes, our laboratory characterizations of gasifier and carbonize ashes have shown that these ashes also have characteristics that might negatively affect filtration. Problems with the durability of the filter elements are being addressed by the development and evaluation of elements constructed from alternative ceramic materials.

    The authors discuss a process developed for hydroisomerization of low-octane naphtha cuts with the aim of obtaining light isoparaffinic hydrocarbons. A zeolitic Ni-Al-Si catalyst with highly dispersed nickel was synthesized. The characteristics of the naphtha cuts used are provided. Data is given on the influence of temperature on destructive hydroisomerization of the 85-195/sup 0/C cut. It is found that the zeolitic Ni-Al-Si catalyst is adequate in activity so that the naphtha cut can be subjected to thorough destructive hydroisomerization through an ionic mechanism with little formation of C/sub 1/ and C/sub 2/ hydrocarbons.

    This paper presents results of an experimental program in which the process of short contact pyrolysis of mixtures of ethane and naphthas has been investigated as an economic alternative way to the production of olefins. The benefits of co-cracking of ethane recycle with naphtha feed in millisecond furnace are demonstrated. There is a directional improvement is selectivity to ethylene product which would result in about 2% less naphtha consumption at constant ethylene production. There is greater operating flexibility in terms of processing additional fresh ethane or LPG, when the furnace area is designed with the co-cracking concept.

    At the present time the project effort is in the TASK 3 stage of operational test cycles. The system operated and functioned completely through the 1st shake-down cycle and is continuing to operate through additional selected demonstration cycles. As noted in the prior No's 9 and 10 quarter, report comments these demonstration cycles with the Marketable Prototype Unit (MPU) are being limited to water as the quench medium. As discussed with my Inventions Coordinator Mr. Jack Aellen recently it is desirable, at this time, to restrict the MPU to water use only. It is anticipated that the project will be completed within the final project date of July 10, 1989. Additional Task 3 Special Testing (with water) is still to be accomplished, however, the writer does not expect any technical problems. Although the project has exceeded original overall budget and schedule estimates, the final project product has completely met expectations.

    Amoco Oil Company is investigating a selective catalytic cracking process to convert the Fischer-Tropsch naphtha and wax fractions to high value transportation fuels. The wax feedstock for this program, a commercial sample of Fischer-Tropsch product from Sasol, is a high melting point, (>220 F), high boiling range (50% boiling above 1,000 F), largely paraffinic material. Work this Quarter centers on the study of various types of HZSM-5 and Y zeolite catalysts. The wax cracking tests on the pilot plant unit were completed last Quarter. The initial product yields have now been corrected for gas and liquid component distribution. Several additional product quality measurements have been completed. The distillate product fraction, boiling between 430--650 F, obtained from the Y zeolite catalyst run, has a high quality Cetane Index of 59. These test results also show high conversion (85%+) of the wax feedstock to light gases and gasoline. The ranking of the three zeolite catalyst types for C{sub 4}-C{sub 5} iso-olefin production is similar to the findings of the small scale screening test program. It is not possible to obtain test results at a wide variety of conversion levels on the pilot plant due to operating constraints.

  6. Deeply etherify FCC light cracked Naphtha (LCN)

    Drastic changes in refinery operations and economics resulting from implementation of environmentally driven U.S. legislation such as the Complex Model in 1998, as well as possible changes beyond that will necessitate several changes. An effective method of adjusting to these process challenges is by deep etherification of the entire FCC light cracked naphtha (LCN) stream, which is the FCC product fraction containing C{sub 5}, C{sub 6} and C{sub 7} hydrocarbons having a typical 1 atm boiling range of 95{degrees}F to 212{degrees}F. Deep etherification technology (DET) can solve five or six problems at once. All U.S. refineries which have an FCC unit have an LCN stream (or possibly a separate LCN stream). Snaprogetti`s LCN DET technology is essentially an upgrade of an otherwise already finished product-which in today`s processing and operations environment, would be sent directly to the gasoline pool. The technology is simply an add-on and does not substantially change refinery operations. As the LCN DET does not require changes in the FCC and catalytic reformer, DET does not cause disturbances to the refinery`s operation.

  7. Optimize syngas to naphtha over ruthenium catalysts

    1984-06-01

    In this work the authors undertake the design of a catalyst system which would efficiently utilize a stream of CO--H/sub 2/, available as a byproduct of partial combustion cracking. The H/sub 2//CO ratio of this stream was fixed by the conditions of the ethylene production process, making it desirable to reject the oxygen in CO as water rather than CO/sub 2/. A second important goal was to maximize the C/sub 2/+ selectivity in order to obtain the highest possible yield of feedstock crackable to ethylene in conventional LPG and naphtha crackers. Using an optimized potassium-promoted, aluminasupported ruthenium catalyst of practical concentration (1% Ru, 0.5% K) on a commercially available support, campaigns of over 1,000 hours on stream were achieved. Impregnation techniques which are readily scaled up were used. During these campaigns the C/sub 2/+ selectivity averaged about 90%. Of the C/sub 2/+ product, about onethird was C/sub 2/-C/sub 5/ while the C/sub 6/+ represents two-thirds.

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.

    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.

    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.

    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.

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.

    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.

  15. Mechanism of aromatic hydrocarbon formation in FCC naphtha

    Mota, C.J.A.; Rawet, R.

    1995-12-01

    A microactivity test study of the FCC naphtha composition at increasing conversions was carried out. At low conversions (ca. 10--20%), the naphtha is rich in olefinic and aromatic hydrocarbons. As the conversion increases, the composition changes dramatically. The olefins initially increase and then decrease sharply. The paraffins increase continually, and the aromatics initially decrease and then increase slightly. The naphthenics remain constant in the conversion range studied. These results indicate that, at low conversions, the aromatics in the gasoline are mainly formed by dealkylation of heavy aromatic molecules present in the feed. At higher conversions, however, the aromatics in the naphtha are mainly formed by cyclization followed by hydrogen transfer of the olefins formed during cracking. This reaction also increases the relative concentration of paraffinic hydrocarbons. The distribution of C9 aromatics showed that, as the conversion increases, there occurs an isomerization of the alkyl chain, to increase the branching of the ring.

    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.

    1984-07-01

    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.

    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.

    A promising path for utilization of secondary naphtha cuts is pyrolysis to produce gaseous feedstocks for petrochemical production. Catalytic pyrolysis in the presence of barium chloride catalysts is of practical interest. The process is carried out without steam dilution of the feed. The effect of feedstock mass velocity in pyrolysis on the gas yield and the total yield is shown. Catalytic pyrolysis offers a means for efficient processing of these feedstocks to obtain olefin-rich gas.

    A natural erionite ore has been exchanged with ammonium and nickel salts to yield a Ni/H erionite catalyst that is active and stable for selectively hydrocracking only the n-paraffins from light straight-run naphthas. The primary product is a C[sup 5+] liquid that is 15-20 octane numbers higher than the feed and a propane- and butane-rich gas by-product. Results from a 110-day pilot plant run demonstrated that a catalyst life of more than 1 year should be possible. Naphthenes, aromatics, and isoparaffins are neither produced nor consumed in this process, resulting in a C[sup 5+] liquid product that is lower in benzene and total aromatics than attainable by catalytic reforming of these feeds. Although no further work is planned with this catalyst, a naphtha-upgrading process based on shape-selective zeolitic hydrocracking could provide an attractive alternative to catalytic reforming or isomerization for these hard to upgrade naphthas. It should be particularly attractive in areas where the by-product propane and butane have good value.

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.

    This is the seventh in a series of quarterly reports describing the activities performed for this project. Our 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 1 during the past quarter, we received and analyzed a hopper ash sample from the Transport Reactor Demonstration Unit (TRDU) located at the University of North Dakota`s Energy and Environmental Research Center (UNDEERC). We also received six ash samples from the Ahlstrom 10 MWt Pressurized Fluidized Circulating Fluid Bed (PCFB) facility located at Karhula, Finland. We selected one of the filter cake ashes from this batch of samples for detailed analyses. We continued our work on the HGCU data base we are constructing in Microsoft Access{reg_sign}. We have been entering a variety of information into the data base, including numerical values, short or long text entries, and photographs. Task 2 efforts during the past quarter focused on hoop tensile testing of Schumacher FT20 and Refractron candle filter elements removed from the Karhula APF after {approximately}540 hours of service.

    The objective of this research is to determine whether or not pulsed excimer laser annealing (PELA) of ion-implanted junctions is a cost effective replacement for diffused junctions of crystalline silicon solar cells. The preliminary economic analysis completed during the first quarter of this program showed that the use of ion implantation and 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 a hypothetical baseline diffusion process that it is assumed to yield cells with an average efficiency of 14%. A cost advantage may be attained, however, if the implant-PELA process yields an improvement in the average cell efficiency from 14 to 16%; this improvement 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 second quarter of this program, it was shown that the laser chosen for this work, operating with an output power of 50 watts, demonstrated sufficient processing speed for commercial production. Also during this time period, the PELA process was optimized for annealing phosphorus implants in polished p-type silicon wafers. The best solar cell obtained in this way had an efficiency of 10.5% at AM1 illumination withour AR coating. This efficiency is equal to that of co-processed furnace annealed ion-implanted controls. Work planned during the next quarter includes optimization of the PELA process parameters for use with screen printed contacts, optimization of the PELA process for use with texture-etched material, and development of a set of parameters to anneal boron or boron-trifluoride implants.

    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.

    This quarterly technical progress report summarizes work completed during the Sixth Quarter of the First Budget Period, January 1 through March 31, 1992, 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. The major emphasis during this reporting period was expanding the test facility to address system integration issues of hot particulate removal in advanced power generation systems. The conceptual design of the facility was extended to include additional modules for the expansion of the test facility, which is referred to as the Power Systems Development Facility (PSOF). A letter agreement was negotiated between Southern Company Services (SCS) and Foster Wheeler (FW) for the conceptual design of the Advanced Pressurized Fluid-Bed Combustion (APFBC)/Topping Combustor/Gas Turbine System to be added to the facility. The expanded conceptual design also included modifications to the existing conceptual design for the Hot Gas Cleanup Test Facility (HGCTF), facility layout and balance of plant design for the PSOF. Southern Research Institute (SRI) began investigating the sampling requirements for the expanded facility and assisted SCS in contacting Particulate Control Device (PCD) vendors for additional information. SCS also contacted the Electric Power Research Institute (EPRI) and two molten carbonate fuel cell vendors for input on the fuel cell module for the PSDF.

    In this quarterly technical Progress report, we summarize the progress which has been achieved with the development of the small angle scattering capability to be used in the current project. In particular, the following was accomplished during the reporting period. The parameter estimation code, MARQFIT, has been tested and is fully operational. The code has been applied to small angle neutron scattering (SANS) data on coals swollen with deuterated solvents. Application of the FPPS model to these data indicated that the large sphere distribution apparently requires a mean greater than 1000{Angstrom}. This was attributed to the influence of interparticle voids. Specific surface areas were also estimated for these coals. Application of this model to the coal chars used in the current project will not be subject to the same effects.

    In this quarterly technical progress report, we summarize some recent steam reactivity data obtained for two different chars - a Wyodak coal char, and a nonmineral matter-containing resin char. In particular, the following was accomplished during the reporting period: Temperature programmed desorption (TPD) spectra obtained from steam-gasified chars were examined. At least two major CO-liberating features were identified for the resin char samples - one centered ca. 1000{degrees}C and the other ca. 1050{degrees}C. The presence of catalytic mineral matter appears to be related to the appearance of an additional low temperature feature for the Wyodak char. Although the total amount of surface oxygen seems to be a gross indicator of reactivity, analysis of the desorption data assuming two different types of oxygen surface complexes, each exhibiting a single desorption activation energy, shows that the reactivity cannot be explained by the desorption rates of the complexes alone.

    1999-05-15

    This report summarizes the technical progress achieved during the fourth quarter of the EPRI project. The focus of work during this reporting period was the construction of an electronic control module for the coke detector probe. The electronic control module supervises the actuation and data collection functions of the probe sensor. Basic operation of the probe controller was confirmed. The overall aim of the project is to demonstrate the performance and practical use of a probe for measuring the thickness of coke deposits located within the high temperature tubes of a thermal cracking furnace. This aim will be met by constructing a probe that will be tested using simulated coke deposits that are positioned inside of a bench-scale furnace. Successful development of the coke detector will provide industry with the only available method for on-line measurement of coke deposits.

    Research is presently being conducted to develop a criteria for selecting weld overlay coatings for erosion mitigation in Circulated Fluidized Beds. Initially, eleven weld overlay alloys were selected for erosion testing based upon a literature review. All eleven coatings were deposited on 1018 steel substrates using the plasma arc welding process. Ten samples from each coating were prepared for erosion testing. The coating deposition and sample preparation procedures were described in the second quarterly report. All selected coatings were erosion tested at 400{degree}C and their erosion resistance was evaluated by determining the steady state erosion rate. In addition, the microstructure of each coating was characterized before and after the erosion tests. The results of the tests are discussed in the third quarterly report. No correlations were found between room temperature hardness of the weld overlay coatings and their erosion resistance at elevated temperature. During the last quarter tensile tests were performed at 400{degree}C for the Ultimet, Inconel-625, 316L SS, C-22, and Stellite-6 wrought alloys. The erosion tests for these materials at 400{degree}C are in progress. The results of mechanical and erosion tests will be used to correlate mechanical properties of selected wrought alloys such as tensile toughness, ductility, strain hardening coefficient and yield strength to their erosion resistance at 400{degree}C. Also, the erosion behavior of the wrought alloys compared with similar weld alloys will be analyzed. The experimental procedure and results of the tensile tests are presented in this progress report.

    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.

The conduct of three tests in the LMF1C series is reported. The status of the environmental monitoring program is reviewed. Preliminary analyses of the test data from the three tests conducted during the quarter are included. The heat fluxes, combustor pressure and combustor efficiencies are reported. The performance of the nozzle, diagnostic (Hall) channel and diffuser is compared with an analytical model for each test run. The performance of the new diffuser which was installed during the quarter is discussed. The test results from the downstream components; i.e. slag screen, radiant furnace, secondary combustor and materials test module, are discussed. Slag removal from the radiant furnace, refractory performance and metals performance is covered. A summary report is included on the results of the cold flow modeling of the secondary combustor, which involved variations in relative velocity of the secondary air, the angle of injection and the flow constriction. Diagnostic support of testing activities is described, including the use of the laser doppler velocimeter (LDV) for the secondary combustor modeling. Luminosity and line reversal temperature measurements were made in support of the CFFF tests. A photodiode line reversal system has been designed which has the promise of being more reliable, easier to install on operational equipment and cheaper.

    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.

    New environmental laws will require the gasoline composition to change dramatically in order to reduce automotive emissions. Auto/Oil studies have indicated that reducing sulfur will lower the emissions of hydrocarbons, NOx, and CO. Since a large portion of the sulfur in the gasoline pool comes from the FCC naphtha, reducing the FCC naphtha sulfur level will lower the sulfur level in the gasoline pool. Hydrotreating the feedstock to the FCC is an effective means of lowering FCC naphtha sulfur. Pilot unit experiments using hydrotreated feeds from Arabian and Alaskan North Slope crudes have shown that the sulfur level in the DB naphtha is reduced dramatically depending on the hydrotreating severity. Cutting the heavy naphtha endpoint will also help lower the sulfur level.

    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). This visit will include on-site sampling to collect and characterize the filter cakes collected during FGB operation. Task 2 efforts during the past quarter focused on

    Catalytic reforming is a refining process that converts naphthenes to aromatics by dehydrogenation to make higher octane gasoline blending components. A portion of this wide boiling range hydrocarbon stream can be separated by distillation and used for other purposes. One such application is a mixture of predominantly 9-carbon aromatic molecules (C9 aromatics, primarily isomers of ethyltoluene and trimethylbenzene), which is removed and used as a solvent--high-flash aromatic naphtha. A program was initiated to assess the toxicological properties of high-flash aromatic naphtha since there may be human exposure through inhalation or external body contact. The current study was conducted partly to assess the potential for mutagenic activity and also to assist in an assessment of carcinogenic potential. The specific tests utilized included the Salmonella/mammalian microsome mutagenicity assay, the hypoxanthine-guanine phosphoribosyl transferase (HGPRT) forward mutation assay in CHO cells, in vitro chromosome aberration and sister chromatid exchange (SCE) assays in CHO cells, and an in vivo chromosome aberration assay in rat bone marrow.

    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.

Also, the erosion tests for these materials at 400{degrees}C were completed. The results of mechanical and erosion tests are used to correlate mechanical properties of selected wrought alloys such as tensile toughness, ductility, strain hardening coefficient and yield strength to their erosion resistance at 400{degrees}C. Preliminary results of correlations between erosion resistance of wrought alloys at 400{degrees}C and their mechanical properties are presented in this progress report.

    The pilot-scale piston-feeder development is progressing satisfactorily and should proceed as planned. The bench scale testing of components, sub-system and critical areas continued to provide very useful information in support of the development of the complete feeder. The K30M seals and polyurethane scrapers are showing very promising results. The components development facility is being upgraded and testing at the bench scale level should be vigorously perused. The upgrading of the pilot scale feeder and its system will be emphasized during the next quarter to perform feeder capabilities and limitations testing. No progress on the 5.5-in. diameter pilot scale screw feeder has been made because IRRI is waiting decision from METC as to when the feeder can be installed on the 42-in. gas producer.

    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.

    Objectives for the first quarter for Task A, Diffusion Coefficients of F-T Products in Supercritical Fluids, were to measure diffusion coefficients of 1-tetradecene in subcritical propane and the diffusion coefficients of 1-octene and 1-tetradecene in subcritical propane and the diffusion coefficients of 1-octene and 1-tetradecene in subcritical and supercritical ethane. We planned to use ethane as a solvent because its lower critical temperature enabled measurements without modification of the existing unit. Our objective was to investigate the behavior of the diffusion coefficients in crossing from subcritical to supercritical conditions. Objectives for Task B, Fischer Tropsch reaction related studies, were: (1) to install and test the temperature probe and the flammable gas detector: (2) to conduct Fischer-Tropsch experiments at baseline conditions and at a high pressure in order to test the newly constructed fixed bed reactor assembly. Accomplishments and problems, are presented.

    Objectives for this quarter were to attempt to develop a model to predict the molecular diffusion coefficients to a high degree of accuracy so the authors may be able to predict both the molecular diffusion coefficient and thus the effective diffusivity a priori. They are working on a semi-empirical equation based on the rough hard sphere theory to predict diffusion coefficients in supercritical fluids. In addition, they planned to take additional data in order to extend the database available for development of the predictive equation. The paper discusses accomplishments and problems related to the diffusion coefficients of F-T products in supercritical fluids. Data are presented on the diffusion coefficients of 1-octene in ethane, propane, and hexane.

    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.

    Research is presently being conducted to develop a criteria for selecting weld overlay coatings for erosion mitigation in Circulated Fluidized Beds. Initially, eleven weld overlay alloys were selected for erosion testing based upon a literature review. All eleven coatings were deposited on 1018 steel substrates using the plasma arc welding process. Ten samples from each coating were prepared for erosion testing. All selected coatings were erosion tested at 400 C and their erosion resistance was evaluated by determining the steady state erosion rate. In addition, the microstructure of each coating was characterized before and after the erosion tests. No correlations were found between room temperature hardness of the weld overlay coatings and their erosion resistance at elevated temperature. It was suggested that weld overlays mechanical properties such as fracture strength, toughness and work hardening rates may contributed to their erosion resistance. During the previous two quarters the microhardness tests were performed on the eroded samples in order to determine the size of the work hardened zone and the change in the coatings hardness due to erosion. As a result of these measurements it was established that one group of coatings deformed plastically, while another did not. In addition, the measurements of the weld overlays microhardness at 400 C were made. The coatings microhardness at 400 C was plotted versus their volume erosion rates. During the last quarter, erosion tests were performed for Inconel-625, 316L SS, and Iron-Aluminide wrought alloys in order to compare their erosion behavior with similar weld overlays. The results of microhardness profile measurements for all weld overlay coatings were analyzed. The factors that contribute to the erosion resistance of the coatings that deformed plastically are discussed in this progress report.

    1998-08-01

    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.

    This quarterly technical progress report summarizes work completed during the Second Quarter of the Second Budget Period, October 1 through December 31, 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: (1) Carbonizer/pressurized circulating fluidized bed gas source; (2) hot gas cleanup units to mate to all gas streams; (3) combustion gas turbine; (4) 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 objective of this project is to demonstrate the preliminary technical and economic feasibility of a novel carbon-based process for removal of at least 95% SO{sub 2} and at least 75% NO{sub x} from coal combustion flue gas. In the process, flue gas leaving the electrostatic precipitator (ESP) is passed through a trickle bed of activated carbon catalyst employing a periodic flush of low strength sulfuric acid. The SO{sub 2} is oxidized to SO{sub 3} and removed as medium strength sulfuric acid. The SO{sub 2}-free flue gas is then mixed with NH{sub 3}, and the NO{sub x} in the gas is subjected to selective catalytic reduction (SCR) to N{sub 2} over a fixed bed of activated carbon catalyst. In the previous three quarters, a detailed project management plan was prepared describing the experimental setup, work plan, and test plan. The experimental system was completed for SO{sub 2} conversion at Waterloo and for NO{sub x} conversion at RTI. Shakedown experiments were completed. In the present quarter, the NO{sub x} removal performance of two additional modified carbon catalysts (MCCII and MCCIII) was studied. MCCII showed NO{sub x} removal efficiency which was similar to that observed for MCCI. However, MCCI was considerably less active for NO{sub x} removal. SO{sub 2} removal experiments with NO present in the feed gas were performed with MCCI. SO{sub 2} removal efficiency was consistently about 98% over each of 10 cycles and was very similar to that observed earlier with no NO present in the feed. Finally, a preliminary economic evaluation of the process was performed and a project review meeting was held. The economic evaluation showed that the Rn-Waterloo process was competitive with SCR/IFGD and other combined SO{sub 2}/NO{sub x}, removal processes.

    The overall goal of this relatively small contractural effort is to provide technical assistance to Dr. Frank Pattern (DARPA) in evaluating data on materials, especially polymers, that may be useful in the development of optical limiters for the protection of eyes and electrooptic sensors from exposure to damaging levels of laser radiation. A major task is to assist in the development of a predictive capability in assessing the viability of various protective approaches and to determine the theoretical limitations which may exist in the use of organic materials as optical switches and limiters. A search of the literature has been initiated in an attempt to gather into one table the magnitude of the nonlinear optical properties of various organic materials as a function of molecular structure. The search includes research activities supported by the Federal Government as well as the open literature.

    This fifth quarterly report covers the period of October through December of 1996. Results are presented of pyrite and HAP precursor removal from Kentucky No. 9 coal in shake flasks and from Indiana No. 5 coal in columns. With Kentucky coal, rates of pyrite oxidation were about 6% per day, and significant As, Co, Cd, Mn, and Ni were removed from the coal. These same five HAP precursors also were significantly removed from Indiana No. 5 coal. Additionally, test results are presented of pyrite and HAP precursor removal from Indiana No. 5 and Pittsburgh No. 8 coal using high initial concentrations of ferric ions. These tests showed faster depyritization of coal than in previous tests done with low initial ferric ion concentrations. In addition, faster and more extensive removal of Cd, Co, Mn, and Ni from Indiana No. 5 coal occurred under high ferric conditions. High solution ferric ion concentration are expected in any biodepyritization process due to progressive biooxidation of pyrite to ferric sulfate. Ferric ions are probably the primary oxidant of pyrite and many of the HAP precursors in coal. Analysis of HAP precursors in Stockton Coal, used by PETC in HAP precursor combustion-mass balance test, was done and compared to PETC analytical data. The INEL slurry column reactor was operated in several shake down runs to prepare for complete HAP precursor removal-mass balance tests. Good separation of coal from ash-forming minerals was observed in these tests.

Several catalyst samples have been prepared by controlled co-precipitation from aqueous mixtures of metal nitrates. The composition of these materials is based on reports of best available catalysts for methanol synthesis, for isobutanol synthesis, and for methanol coupling reactions. The mechanical construction and pressure testing of the microreactor system has been completed. The in-situ infrared spectrophotometer equipped with a nitrogen purge is fully operational. The temperature-programmed surface reaction (TPSR) unit has been designed; construction will begin during the third quarter FY`95. Air Products and Chemicals has provided us with a sample of a BASF isobutanol synthesis catalyst and with catalytic data obtained on this catalyst in a LaPorte test run.

Work on the CFFF progressed with only minor problems. Total construction activity for all site work presently awarded is nearly 98% complete. Water analysis shows that Woods Reservoir baseline conditions are within EPA or Tennessee drinking water standards. For the primary combustor, the vitiation heater and primary combustor fabrication drawings were completed and the nozzle design was completed. The drum module for the radiant slagging furnace was awarded. On the MHD Power Generator, development continued in several areas of advanced analysis including development of time-dependent models for use with the one-dimensional code. For seed regeneration, the tentative determination is that the Tomlinson Tampella is the most economically viable method. With regard to capped electrode erosion, investigations have shown that the major degradation of the cladding still present is at the leading edge of the capped anode. To alleviate this, plans are to hot work the noble metal in the bending operation. In resolving another problem, a system employing the modified line-reversal method has been assembled and successfully tested to measure absolute plasma temperatures.

    The scope of work covered by this quarterly report encompasses prototypical combustor and channel design studies, design support engineering for the prototypical hardware, and 50 MW/sub t/ power train testing data analysis. A new TRW design concept was developed for cooling the prototypical combustor which utilizes modular cooling panels. The new design offers improved maintainability and scalability over the originally proposed design. Avco performed design analyses to define aspect ratios for the prototypical channel. The operating conditions for the channel are being determined in conjunction with TRW. Fabrication of the prototypical current controls continued. Avco continued development testing in the Mark VII facility to provide design data for the prototypical 1A4 channel. Testing focused on evaluating methods for obtaining transverse conductivity measurements and on the effects of cathode slag shorting on generator performance. Westinghouse completed detailed designs for the breadboard power consolidation circuitry for the Mark VII generator. Fabrication and performance verification testing of these circuits is well underway. The data acquisition and monitor system for the bread-board consolidation circuits was also designed. The 50 MW/sub t/ workhorse power train was tested under conditions of 100% slag carryover. Results showed only a slight decrease in power output from the nominal 50% carryover baseline. Analyses indicate that performance is much more sensitive to slag carryover in the zero to 30% range. 4 refs., 78 figs., 14 tabs.

They are developing a Flexible Battery Charger Control Board, a Battery Charger Test Stand, and writing software that can be used with both. The status is as follows: (a) Flexible Battery Charger Control Board -- a preliminary electrical design is complete. They are now investigating how the control design might incorporate provisions for an additional Electric Vehicle charging feature. This additional design is based on SAE J2293 -- Recommended Practice for EV Communications. Investigation of J2293 is being considered for controlling a power supply using proprietary Capacitive Charging Coupler, and controlling the power supply with this control board. (b) Battery Test Stand -- the preliminary hardware design is complete. The design includes some very desirable additions to the specifications, including an AC line source for the charger being tested and a battery simulator. Purchasing of the equipment and materials for the test stand is underway. The engineers have been working in the SAE standards setting committees for Electric Vehicles for several years. In particular, they have been working to set the Capacitive Coupler as the standard for connecting an EV to the utility grid system. Substantial test data has been distributed to the committee members on the Conductive and Inductive Charging Systems. It is their opinion that they have a superior coupling mechanism, and they are proceeding to develop this technology.

    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.

    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.

    During this quarter we have tested and calibrated six thermocouples of the temperature probe assembly. We obtained additional information on potential supercritical fluids from several vendors. We found out that all three potential supercritical solvents (propane, butane, and hexane) have less than 1 ppM sulfur impurities, whereas the maximum amount of sulfur in the feed should be less than 0.05 ppM. This remains to be a potential problem, since high levels of sulfur in the feed will result in catalyst poisoning. However, this would be the case with all three potential solvents, and thus we have decided to use propane as the supercritical fluid in our reaction studies based on its cost and favorable supercritical properties. In our shake down tests we will not use a catalyst guard bed for sulfur removal. If we experience problems with catalyst deactivation due to sulfur in feed, the guard bed will be installed in the propane feed line. We have ordered 1-tetradecene and will begin measuring diffusion coefficients of this compound in subcritical propane.

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.

    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.

    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.

    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.

    The primary objective of this study is to investigate the removal organic sulfur from selectively oxidized Illinois coals using mild thermal/chemical processes. Work completed this quarter primarily concerned the investigation of the desulfurization of the selectively oxidized coals using aqueous or alcoholic base mixtures. Model compound studies were initiated. Results were: Levels of desulfurization obtained in this study are at, or very close to, the 90% removal levels required for these coals to be in compliance with the Clean Air Act legislation; Up to 89.4% of the sulfur in the IBC 101 coal and 88.9% of the sulfur in the IBC 106 coal has been removed by combining selective oxidation and alcoholic/base reactions; Overall, selective oxidation pretreatment always led to a lower sulfur product than the untreated sample; Substantial enhancement in the reactivity of the sulfur in the coal has been achieved by the selective oxidation pretreatment; The highest levels of desulfurization obtained so far all involve bases as additives; The water/Na{sub 2}CO{sub 3} combination, was superior than any of the aqueous hydroxide bases. Possible synergistic interactions between the alcohol and the base are suspected. Over 70% of the sulfur in the IBC 101 coal can be removed by performing vacuum pyrolysis on the selectively oxidized coal. Lower sulfur contents are obtained by lowing the pyrolysis pressure.

    The primary objective of this study is to investigate the removal organic sulfur from selectively oxidized Illinois coals using mild thermal/chemical processes. Work completed this quarter primarily concerned establishing the level of selective oxidation required for successful desulfurization in subsequent treatments. Many desulfurization reactions were performed on pretreated as well as unoxidized coal. The results obtained support the following new conclusions: (1) The extent of selective oxidation in the pretreatment step does not effect the level of desulfurization obtained by pyrolysis alone. However this factor was important in the desulfurization obtained with supercritical methanol (SCM)/base. (2) Up to 84% of the sulfur in the IBC 106 coal and 86% of the sulfur in the IBC 106 coal has been removed by combining selective oxidation and SCM/base reactions. (3) Most desulfurizations at 250{degree}C did not produce significant levels of desulfurization. However as the temperature was increased levels of desulfurization increased considerably. (4) Although aqueous base was successful in removing sulfur from both pretreated and untreated samples, the most pronounced desulfurizations were obtained for the untreated samples. This is explained primarily by the dissolution of pyrite in the untreated samples. (5) The best desulfurizations involved SCM and base. Possible synergistic interactions between the methanol and the base are suspected. (6) Overall, selective oxidation pretreatment always led to a lower sulfur product. The severity of desulfurization is reduced by selective oxidation pretreatment.

    The mild gasification of coal is a promising new technology that can convert coal to multiple products: gas, solid, and liquids. However, the sulfur content and aromaticity of mild gasification liquids limits their usefulness. Biodesulfurization can potentially decrease both sulfur content and aromaticity. The objective of this project is to investigate the feasibility of using biodesulfurization to upgrade the quality of mild gasification liquids. Previously it was shown that the middle distillate (360--440{degrees}F) fraction of liquids derived from the mild gasification of coal could be biodesulfurized. During this quarter it was demonstrated that unfractionated liquids can be biodesulfurized. Moreover, it was demonstrated that lysed cell preparations and freeze-dried cells can be used to biodesulfurize mild coal gasification liquids. The importance of the finding that freeze-dried biocatalysts can be used to biodesulfurize mild coal gasification liquids is that freezedried cells can be produced at one location, stored indefinitely, and then shipped to another location for coal biodesulfurization. Moreover, freeze-dried biocatalysts can be added directly to mild coal gasification liquids with only minimal additions of water so that reactor volumes can be minimized.

    The purpose of this project is to develop an advanced coal-combustion system for industrial boilers. With the new combustion system, coal could be used to replace oil and possibly gas as fuel for many industrial boilers. The advanced combustion system is comprised of several parts: (1) A new burner-design concept for coal fuels, developed from the familiar gas turbine combustor-can designs that have proven efficient, reliable, durable, and safe for the combustion of liquid fuel oils. (2) A coal storage and dense-phase feed system for injecting clean, ultrafine pulverized coal into the burner at a low velocity. (3) An automatic control system based on feedback from low-cost automotive combustion-quality transducers. A cold flow model of an initial phase of the new burner design and the associated laser flow-visualization techniques were developed during this quarter. A series of modifications of the initial cold flow model will be tested to establish details of design for the new burner. Also a 200 hp firetube boiler has been installed and tested using number 2 oil as a fuel. This boiler will be used for future combustion testing with the new burner and ultrafine pulverized coal. Additionally an ultrafine-coal injector has been designed which will be evaluated separately as a replacement for the oil gun in the firetube boiler. Two tons of deep-cleaned, ultrafine coal were received for initial tests with the coal injector.

    The objective for this quarter was to test the advanced hybrid particulate collector (AHPC) in real flue gas conditions. The initial tests were performed on the particulate test combustor (PTC) firing Absoloka subbituminous using two types of bags: PTFE and graphite-impregnated PTFE. Both bag types were evaluated in the on-line and off-line cleaning modes. Findings showed only a small difference in performance between the PTFE and graphite-impregnated PTFE. In the on-line cleaning mode, both the PTFE and graphite-impregnated PTFE bags maintained pressure drop across the bags of between 8.0 and 6.0 in. W.C. In the off-line mode, the pressure drop across both bag types ranged from 8.0 to 5.5 in. W.C. Dust-loading efficiencies averaged 99.986% over all the tests. The objective of the project is to develop a highly reliable AHPC that can provide > 99.99% particulate collection efficiency for all particle sizes from 0.01 to 50 {micro}m, is applicable for use with all US coals, and is cost-comparative with existing technologies.

    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.

    The Project Team accomplished two tasks during the third quarter: preparation and presentation of professional papers; and development of simulation models and sub models of the hypothetical variable wall mining installation. 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.

    The goal of this project is to characterize marketed coals from Illinois mines. The characterization parameters that are being determined include the concentration of all trace and minor elements that are of environmental concern, proximate and ultimate compositions, the pyrite size distribution and maceral association, preliminary froth flotation cleanability, slagging and fouling characteristics relevant to the coal`s behavior in utility boilers, chlorine forms and distribution, and certain gasification and rheology parameters. During the third quarter, the trace element data base on Illinois coals was fully checked and edited. The determinations of the trace and minor element contents and proximate and ultimate compositions of the 34 project samples were largely completed. The pyritic S content, still high in some of the marketed samples, could be reduced further in the samples by advanced physical cleaning techniques. Results from the analysis of all 34 samples for Ba, Hg, Mn, and Zr indicate that these elements are primarily or partly associated with mineral matter and, therefore, their concentrations could also be reduced further in the product coals by advanced physical cleaning techniques. A sequential extraction of Cl from two of the samples revealed that regardless of the initial chlorine concentration of the two coals, the total combined amount of chlorine extracted by water, ammonia, and sodium hydroxide is about the same.

    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.

    The objective of this Korean/United States/laboratory/university collaboration is to develop new advanced computational methods for safety analysis codes for very-high-temperature gas-cooled reactors (VHTGRs) and numerical and experimental validation of these computer codes. The research will improve two well-respected light water reactor transient response codes (RELAP5/ATHENA and MELCOR) in the modeling of molecular diffusion and chemical equilibrium, and to validate these codes against the VHTGR accident data, i.e., air ingress and others from the literature. The VHTGR is intrinsically safe, has a proliferation-resistant fuel cycle, and many advantages relative to light water reactors (LWRs). This study consists of five tasks for FY-03: (1) development of computational methods for the VHTGR, (2) theoretical modification of aforementioned computer codes for molecular diffusion (RELAP5/ATHENA) and modeling CO and CO{sub 2} equilibrium (MELCOR), (3) development of a state-of-the-art methodology for VHTGR neutronic analysis and calculation of accurate power distributions and decay heat deposition rates, (4) reactor cavity cooling system experiment, and (5) graphite oxidation experiment. First quarter of Year 3: (A) Prof. NO and Kim continued Task 1. We first performed the chemical reaction test for the VELUNA pebble oxidation experiment and then the analysis of the air ingress accident for PBMR 268MWt. In the GAMMA analysis, significant rise in pebble temperature was observed at the bottom of the core due to graphite oxidation. Since the air ingress process depends on the vault conditions, further analysis coupled with more detailed vault or containment modeling would be necessary as a future study. (B) Prof. Park continued Task 2. The experiments for SNU-RCCS were continued to provide the experimental data for the validation of the thermal hydraulic code being developed at KAIST and to evaluate the performance of the system using the experiments and system analysis

    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.

    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.

    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.

    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.

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.

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.

    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.

    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.

    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.

    A substantial desulphurisation of an 80-180/sup 0/C gasoline fraction obtained from a partially, thermally cracked naphtha was possible by the use of a high iron clay. The operation was carried out by the contact of the gasoline vapours with a fixed-bed of the clay in a laboratory assembled quartz tube reactor. It was possible to reduce the sulphur content of the gasoline fraction from 0.3 wt% to 0.03 wt% at a temperature of 600/sup 0/ and a space velocity of 1.0 h/sup -1/. Analysis of the clay samples are given and the results on its role in desulphyrisation may point to some important potentials.

    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.

    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.

    This eleventh Quarterly Technical Progress Report presents the results of work accomplished during the period April 1, 1992 through June 30, 1992 under Contract No. DE-AC21-88MC26367 entitled ``Production of Low-Cost Hydrogen.`` The overall objective of this program is to verify the ability of the MTCI indirectly heated fluid-bed gasifier to produce a hydrogen-rich product gas from liquefaction by-product streams and from char produced in mild gasification processes. The characterization unit was renovated and another burner/exhaust designed to replace the one that has been in use for several years. Initial shakedown tests for bed calcination indicated that the gasifier should be changed with fresh limestone and kept at temperature, with whatever make-up was required to maintain bed height until calcination was completed as determined by the CO concentration. Char gasification was then initiated and two relatively long-term tests (15.5 and 10.5 hours) were completed at two different temperatures.

The circuit will utilize an extremely fine, micron-sized magnetite media and small diameter cyclones to make efficient density separations on minus-28-Mesh coal. The overall objectives of the project are to: Determine the effects of operating time on the characteristics of the recirculating medium in a continuous integrated processing circuit, and subsequently, the sensitivity of cyclone separation performance to the quality of the recirculating medium; and determine the technical and economic feasibility of various unit operations and systems in optimizing the separation and recovery of the micronized magnetite from the coal 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.

    The objective of this project is to provide detailed information on methods of minimizing soot formation during synthetic liquid fuel combustion under conditions which minimize fuel nitrogen conversion to nitric oxide. The program consists of two tasks. The purpose of the first task, Fuel Screening Studies, is to investigate the impact of fuel properties on particulate production, to establish the importance of droplet size and examine atomizer effects, and to develop techniques for surrogate fuels productions. In the second task, Flame Studies, the fundamental details of soot formation from synfuel droplet combustion will be investigated in variable slip velocity configurations. This present report describes technical progress during the first three months of the program effort (October-December 1980). During this initial period, attention has focused on the definition of the different experimental efforts and on the design and construction of the required hardware. Aspects of this work are discussed.

    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.

    Oil companies are expecting wider mandated use of reformulated gasolines and further environmental mandates to lower sulfur contents of reformulated gasolines in the near future. Environmental agencies currently believe that lower sulfur contents will significantly upgrade the quality of automotive exhaust gases. Most of the sulfur in a typical refinery gasoline pool comes from {open_quotes}cracked naphthas,{close_quotes} e.g. from Fluid Catalyst Cracking Units (FCCU`s). Cracked naphthas also have high olefin contents, and thus, high octane numbers. Although it is relatively easy to remove sulfur from a cracked naphtha in a low severity hydrotreating operation, at the same time, significant olefin saturation and octane reduction occur. Clearly, a selective hydrodesulfurization (HDS) process with minimal olefin reduction is required to produce low sulfur, high octane cracked naphthas. 2 refs., 5 tabs.

    In order to cope with the increasing demand for gasoline and the need to reduce environmental impact for sustainable development, refineries have installed refining technology by introducing cracking, reforming, isomerization and alkylation. The standard EN 228: 2004 outlines the specification that gasoline, deriving from the blend of several fractions, must have for use in modem piston engines. Naphtha is one of the products from distilling crude oil that can be used as starting material in the reforming process whose derivatives, which are a fraction of gasoline, depend on the composition of the naphtha. Knowledge of the naphtha composition thus enables to provide the final composition of the products of reforming, the efficiency of the plant and also provides information about the crude oil used. In this paper some naphtha samples were analysed by multidimensional gas chromatography. This technique allows in a single analysis a good separation of the hydrocarbon types and within each hydrocarbon type a good carbon number separation. PMID:17172208

    The objective of this program is to provide the engineering tools necessary for an authoritative assessment of the performance of industrial furnaces firing pulverized coal. The program incorporates two experimental tasks and is constructed around an analytical task which will identify and upgrade the family of computer programs required to undertake the performance analysis studies. These analytical tools will be used to predict the effect of parameters such as fuel type and furnace variables on combustor performance, and to identify those properties which have a major impact on thermal performance. The second task uses a combustion reactor to screen the key variables identified and to provide data on the properties of coal particulate matter which affect heat transfer performance. Verification of the engineering analytical approach will be provided by measurements made in a pilot-scale furnace. This present report discusses technical progress during the first three months of the program, and considers the selection of the appropriate analytical tools and preliminary details of the experimental system.

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.

  7. Biochemical removal of HAP precursors from coal. Quarterly technical progress report, 1996

    1996-12-31

    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 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.

    Work was performed in the following areas of the Pipeline Gas Demonstration Plant Program: site evaluation and selection; demonstration plant environmental analysis; feedstock plans, licenses, permits and easements; demonstration plant definitive design; construction planning; economic reassessment; technical support; long lead procurement list; and project management. Major work activity continued to be the effort on Demonstration Plant Definitive Design. A Construction Readiness Audit was held on January 14 to 16, 1981 by a Government/Procon team to review the project and assess the readiness of the project to proceed into the construction phase. Documents for the 60% Design Review were prepared for ICGG review and submitted to the Contracting Officer's authorized representative prior to transmittal to the Corps of Engineers for review. The Corps of Engineers conducted a design audit. The primary objective of the audit was to prepare an independent estimate of the work remaining to complete Phase I of the project. Work continued on the production of a single bid package for the Demonstration Plant, suitable for release to a single constructor, and organized so it can be easily broken down into subpackages by construction specialty. A formal audit of the ICGG R/QA Plan and implementation thereof was performed February 11-12, 1981 by the Corps of Engineers. The Contract Deliverable Final Feedstock-Product-Waste Disposal Plan was delivered to the Government on February 25, 1981.
