Sample records for midwestern gasoline prices

  1. Price changes in the gasoline market: Are Midwestern gasoline prices downward sticky?

    SciTech Connect

    1999-03-01

    This report examines a recurring question about gasoline markets: why, especially in times of high price volatility, do retail gasoline prices seem to rise quickly but fall back more slowly? Do gasoline prices actually rise faster than they fall, or does this just appear to be the case because people tend to pay more attention to prices when they`re rising? This question is more complex than it might appear to be initially, and it has been addressed by numerous analysts in government, academia and industry. The question is very important, because perceived problems with retail gasoline pricing have been used in arguments for government regulation of prices. The phenomenon of prices at different market levels tending to move differently relative to each other depending on direction is known as price asymmetry. This report summarizes the previous work on gasoline price asymmetry and provides a method for testing for asymmetry in a wide variety of situations. The major finding of this paper is that there is some amount of asymmetry and pattern asymmetry, especially at the retail level, in the Midwestern states that are the focus of the analysis. Nevertheless, both the amount asymmetry and pattern asymmetry are relatively small. In addition, much of the pattern asymmetry detected in this and previous studies could be a statistical artifact caused by the time lags between price changes at different points in the gasoline distribution system. In other words, retail gasoline prices do sometimes rise faster than they fall, but this is largely a lagged market response to an upward shock in the underlying wholesale gasoline or crude oil prices, followed by a return toward the previous baseline. After consistent time lags are factored out, most apparent asymmetry disappears.

    Limited literature suggests that gasoline prices have substantial effects on reducing fatal crashes. However, the literature focuses only on fatal crashes and does not examine the effects on all traffic crashes. Mississippi traffic crash data from April 2004-December 2008 from the Mississippi Highway Patrol and regular-grade unleaded gasoline price data from the Energy Information Administration of the U.S. Department of Energy were used to investigate the effects of gasoline prices on traffic safety by age, gender, and race. Gasoline prices have both short-term and intermediate-term effects on reducing total traffic crashes and crashes of females, whites, and blacks. The intermediate-term effects are generally stronger than the short-term effects. Gasoline prices also have short-term effects on reducing crashes of younger drivers and intermediate-term effects on older drivers and male drivers. Higher gasoline taxes reduce traffic crashes and may result in additional societal benefits. Copyright © 2010 Elsevier Ltd. All rights reserved.

  6. Consumer expectations for future gasoline prices

    A key finding of this study is that consumer expectations respond to the volatility in retail gasoline prices. Historical price trends can be characterized as a series of rapid steps separated by varying periods of relative stability. The behavorial models investigated here imply that consumer response to downward steps is constrained by the effect of the longer-term (less volatile) trends. The response to upward steps is, however, essentially unconstrained in that it can be driven directly through the short-term price trend. The rough trajectory by which retail gasoline prices have climbed historically thus appears to sustain relatively high consumer expectations for future price levels. In a second point of divergence, analytical efforts also generally employ real price trends. While arguably the basis for decision-making by business planners and analysts, it does not necessarily hold that consumers discount nominal price trends for expected inflation rates in developing their year-ahead price forecasts. An initial review of the SRC data for expected real price increases (expected prices adjusted for the expected inflation rate) identified no consistent relationships, and generally lower correlations, with historical trends in real prices.

  7. Three studies of retail gasoline pricing dynamics

    NASA Astrophysics Data System (ADS)

    Atkinson, Benjamin James

    In many Canadian cities, retail gasoline prices appear to cycle, rising by large amounts in one or two days followed by several days of small consecutive price decreases. While many empirical studies examine such markets, certain questions cannot b e properly answered without high frequency, station-specific price data for an entire market. Thus, the first paper in this thesis uses bi-hourly price data collected for 27 stations in Guelph, Ontario, eight tunes per day for 103 days to examine several basic predictions of the Edgeworth cycle theory. The results are largely consistent with this theory. However, most independent firms do not tend to undercut their rivals' prices, contrary to previous findings. Furthermore, the tuning, sizes and leaders of price increases appear to be very predictable, and a specific pattern of price movements has been detected on days when prices increase. These findings suggest that leading a price increase might not be as risky as one may expect. The second paper uses these same data to examine the implications o f an informal theory of competitive gasoline pricing, as advanced by industry and government. Consistent with this theory, stations do tend to set prices to match (or set a small positive or negative differential with) a small number of other stations, which are not necessarily the closest stations. Also, while retailers frequently respond to price changes within two hours, many take considerably longer to respond than is predicted by the theory. Finally, while price decreases do ripple across the market like falling dominos, increases appear to propagate based more on geographic location and source of price control than proximity to the leaders. The third paper uses both these data and Guelph price data collected every 12 hours during the same 103 days from OntarioGasPrices.com to examine the sample selection biases that might exist in such Internet price data, as well as their implications for empirical research.

    Gasoline taxes are considered to be a cost-effective policy instrument for reducing carbon emissions. A study finds that while gasoline taxes rose in 83 countries between 2003 and 2015, the global mean fell by 13.3% due to a shift in consumption towards countries that maintain gasoline subsidies or that have low taxes.

  9. Assessment of Summer 1997 motor gasoline price increase

    SciTech Connect

    1998-05-01

    Gasoline markets in 1996 and 1997 provided several spectacular examples of petroleum market dynamics. The first occurred in spring 1996, when tight markets, following a long winter of high demand, resulted in rising crude oil prices just when gasoline prices exhibit their normal spring rise ahead of the summer driving season. Rising crude oil prices again pushed gasoline prices up at the end of 1996, but a warm winter and growing supplies weakened world crude oil markets, pushing down crude oil and gasoline prices during spring 1997. The 1996 and 1997 spring markets provided good examples of how crude oil prices can move gasoline prices both up and down, regardless of the state of the gasoline market in the United States. Both of these spring events were covered in prior Energy Information Administration (EIA) reports. As the summer of 1997 was coming to a close, consumers experienced yet another surge in gasoline prices. Unlike the previous increase in spring 1996, crude oil was not a factor. The late summer 1997 price increase was brought about by the supply/demand fundamentals in the gasoline markets, rather than the crude oil markets. The nature of the summer 1997 gasoline price increase raised questions regarding production and imports. Given very strong demand in July and August, the seemingly limited supply response required examination. In addition, the price increase that occurred on the West Coast during late summer exhibited behavior different than the increase east of the Rocky Mountains. Thus, the Petroleum Administration for Defense District (PADD) 5 region needed additional analysis (Appendix A). This report is a study of this late summer gasoline market and some of the important issues surrounding that event.

    This study investigates the relationship between changing gasoline prices and drunk-driving crashes. Specifically, we examine the effects of gasoline prices on drunk-driving crashes in Mississippi by several crash types and demographic groups at the monthly level from 2004 to 2008, a period experiencing great fluctuation in gasoline prices. An exploratory visualization by graphs shows that higher gasoline prices are generally associated with fewer drunk-driving crashes. Higher gasoline prices depress drunk-driving crashes among young and adult drivers, among male and female drivers, and among white and black drivers. Results from negative binomial regression models show that when gas prices are higher, there are fewer drunk-driving crashes, particularly among property-damage-only crashes. When alcohol consumption levels are higher, there are more drunk-driving crashes, particularly fatal and injury crashes. The effects of gasoline prices and alcohol consumption are stronger on drunk-driving crashes than on all crashes. The findings do not vary much across different demographic groups. Overall, gasoline prices have greater effects on less severe crashes and alcohol consumption has greater effects on more severe crashes.

    I find evidence of a negative association between gasoline prices and body weight using a fixed effects model with several robustness checks. I also show that increases in gas prices are associated with additional walking and a reduction in the frequency with which people eat at restaurants, explaining their effect on weight. My estimates imply that 8% of the rise in obesity between 1979 and 2004 can be attributed to the concurrent drop in real gas prices, and that a permanent $1 increase in gasoline prices would reduce overweight and obesity in the United States by 7% and 10%.

    We examined whether sales of new motorcycles was a mechanism to explain the relationship between motorcycle fatalities and gasoline prices. The data came from the Motorcycle Industry Council, Energy Information Administration and Fatality Analysis Reporting System for 1984-2009. Autoregressive integrated moving average (ARIMA) regressions estimated the effect of inflation-adjusted gasoline price on motorcycle sales and logistic regressions estimated odds ratios (ORs) between new and old motorcycle fatalities when gasoline prices increase. New motorcycle sales were positively correlated with gasoline prices (r = 0.78) and new motorcycle fatalities (r = 0.92). ARIMA analysis estimated that a US$1 increase in gasoline prices would result in 295,000 new motorcycle sales and, consequently, 233 new motorcycle fatalities. Compared to crashes on older motorcycle models, those on new motorcycles were more likely to be young riders, occur in the afternoon, in clear weather, with a large engine displacement, and without alcohol involvement. Riders on new motorcycles were more likely to be in fatal crashes relative to older motorcycles (OR 1.14, 95 % confidence interval (CI) 1.02-1.28) when gasoline prices increase. Our findings suggest that, in response to increasing gasoline prices, people tend to purchase new motorcycles, and this is accompanied with significantly increased crash risk. There are several policy mechanisms that can be used to lower the risk of motorcycle crash injuries through the mechanism of gas prices and motorcycle sales such as raising awareness of motorcycling risks, enhancing licensing and testing requirements, limiting motorcycle power-to-weight ratios for inexperienced riders, and developing mandatory training programs for new riders.

  15. An analysis of strategic price setting in retail gasoline markets

    NASA Astrophysics Data System (ADS)

    Jaureguiberry, Florencia

    This dissertation studies price-setting behavior in the retail gasoline industry. The main questions addressed are: How important is a retail station's brand and proximity to competitors when retail stations set price? How do retailers adjust their pricing when they cater to consumers who are less aware of competing options or have less discretion over where they purchase gasoline? These questions are explored in two separate analyses using a unique datasets containing retail pricing behavior of stations in California and in 24 different metropolitan areas. The evidence suggests that brand and location generate local market power for gasoline stations. After controlling for market and station characteristics, the analysis finds a spread of 11 cents per gallon between the highest and the lowest priced retail gasoline brands. The analysis also indicates that when the nearest competitor is located over 2 miles away as opposed to next door, consumers will pay an additional 1 cent per gallon of gasoline. In order to quantify the significance of local market power, data for stations located near major airport rental car locations are utilized. The presumption here is that rental car users are less aware or less sensitive to fueling options near the rental car return location and are to some extent "captured consumers". Retailers located near rental car locations have incentives to adjust their pricing strategies to exploit this. The analysis of pricing near rental car locations indicates that retailers charge prices that are 4 cent per gallon higher than other stations in the same metropolitan area. This analysis is of interest to regulators who are concerned with issues of consolidation, market power, and pricing in the retail gasoline industry. This dissertation concludes with a discussion of the policy implications of the empirical analysis.

    Determine the relationships between cycling and urban sprawl and between cycling and the gasoline price. Cross-sectional multivariate regression analyses using pooled data from two individual-level national surveys to analyze the effects of variations in levels of urban sprawl and the gasoline price on cycling as a form of physical activity. Metropolitan areas representative of the U.S. population, 1990 to 2001. Behavioral Risk Factor Surveillance System: 146,730 individuals at least 18-years-old in the United States; Nationwide Personal Transportation Survey: 73,903 individuals at least 18-years-old in the United States. Self-reported information on bicycling served as the dependent variable. Urban sprawl and the gasoline price served as key independent variables. Living in a metropolitan area with a lower degree of urban sprawl increased the probability of cycling in the past month by 3.4 to 4.4 percentage points and 1.6 to 2.1 percentage points from the means for men and women, respectively. Increasing the gasoline price by one dollar increased the probability of cycling by 4.3 to 4.7 percentage points and 2.9 to 3.5 percentage points for men and women, respectively. Results indicate that the prevalence of cycling is higher in less sprawling areas and areas with higher gasoline prices. More research is needed to refine results on how individuals respond to incentives and the roles that monetary and time costs play in improving public health.

  17. Gasoline prices and traffic crashes in Alabama, 1999-2009.

    The price of gasoline has been found to be negatively associated with traffic crashes in a limited number of studies. However, most of the studies have focused either on fatal crashes only or on all crashes but measured over a very short time period. In this study, we examine gasoline price effects on all traffic crashes by demographic groups in the state of Alabama from 1999 to 2009. Using negative binomial regression techniques to examine monthly data from 1999 to 2009 in the state of Alabama, we estimate the effects of changes in gasoline price on changes in automobile crashes. We also examine how these effects differ by age group (16-20, 21-25, 26-30, 31-64, and 65+), gender (male and female), and race/ethnicity (non-Hispanic white, non-Hispanic black, and Hispanic). The results show that gasoline prices have both short-term and long-term effects on reducing total traffic crashes and crashes of each age, gender, and race/ethnicity group (except Hispanic due to data limitations). The short-term and long-term effects are not statistically different for each individual demographic group. Gasoline prices have a stronger effect in reducing crashes involving drivers aged 16 to 20 than crashes involving drivers aged 31 to 64 and 65+ in the short term; the effects, however, are not statistically different across other demographic groups. Although gasoline price increases are not favored, our findings show that gasoline price increases (or decreases) are associated with reductions (or increases) in the incidence of traffic crashes. If gasoline prices had remained at the 1999 level of $1.41 from 1999 to 2009, applying the estimated elasticities would result in a predicted increase in total crashes of 169,492 (or 11.3%) from the actual number of crashes. If decision makers wish to reduce traffic crashes, increasing gasoline taxes is a possible option-however, doing so would increase travel costs and lead to equity concerns. These findings may help to shape transportation

    Existing literature shows negative relationships between gasoline price and motor vehicle crashes, particularly among teens. This paper extends that literature by evaluating the relationship between gasoline price and self-reported risky driving among teens. Observational study using multivariate empirical analysis, using pooled data from the Youth Risk Behavior Survey, waves 2003-2009. Secondary data from survey administered in private and public high schools across the United States. Students in grades 9 through 12, surveyed biennially from 2003 to 2009 (n = 58,749). Outcomes are (self-reported) driving without seatbelts, driving after consuming alcohol, and moderate physical activity (like walking or bicycling). State-level retail gasoline prices constitute the main predictor variable. Multivariate logistic models are estimated for the full sample, as well as by gender, race/ethnicity, and age. Individual characteristics, state unemployment, and state driving policies are controlled for. Standard errors are clustered at the state level. Results are reported in form of risk differences. Higher gasoline prices are negatively and significantly associated with driving without seatbelts. Associations are particularly strong for males and minorities. There are fewer statistical associations between gasoline prices and driving after drinking. Higher gasoline prices are positively associated with more moderate physical activity. Higher gasoline prices are associated with less risky driving behaviors among teens, and they may be associated with more active forms of transportation, like walking and bicycling. The study limitations are discussed.

  19. Product differentiation, competition and prices in the retail gasoline industry

    NASA Astrophysics Data System (ADS)

    Manuszak, Mark David

    This thesis presents a series of studies of the retail gasoline industry using data from Hawaii. This first chapter examines a number of pricing patterns in the data and finds evidence that gasoline stations set prices which are consistent with a number of forms of price discrimination. The second chapter analyzes various patterns of cross-sectional, cross-market and intertemporal variation in the data to investigate their suitability for use in structural econometric estimation. The remainder of the dissertation consists of specification and estimation of a structural model of supply and demand for retail gasoline products sold at individual gasoline stations. This detailed micro-level analysis permits examination of a number of important issues in the industry, most notably the importance of spatial differentiation in the industry. The third chapter estimates the model and computes new equilibria under a number of asymmetric taxation regimes in order to examine the impact of such tax policies on producer and consumer welfare as well as tax revenue. The fourth chapter examines whether there is any evidence of tacitly collusive behavior in the Hawaiian retail gasoline industry and concludes that, in fact, conduct is fairly competitive in this industry and market.

    We investigated how much time passes before gasoline price changes affect traffic crashes. We systematically examined 2004 to 2012 Mississippi traffic crash data by age, gender, and race. Control variables were unemployment rate, seat belt use, alcohol consumption, climate, and temporal and seasonal variations. We found a positive association between higher gasoline prices and safer roads. Overall, gasoline prices affected crashes 9 to 10 months after a price change. This finding was generally consistent across age, gender, and race, with some exceptions. For those aged 16 to 19 years, gasoline price increases had an immediate (although statistically weak) effect and a lagged effect, but crashes involving those aged 25 to 34 years was seemingly unaffected by price changes. For older individuals (≥ 75 years), the lagged effect was stronger and lasted longer than did that of other age groups. The results have important health policy implications for using gasoline prices and taxes to improve traffic safety.

    Estimating the consumer demand response to changes in the price of gasoline has important implications regarding fuel tax policies and environmental concerns. There are reasons to believe that the short-run price elasticity of gasoline demand fluctuates due to changing structural and behavioral factors. In this paper I estimate the short-run price elasticity of gasoline demand in two time periods, from 2001 to 2006 and from 2007 to 2010. This study utilizes data at both the national and state levels to produce estimates. The short-run price elasticities range from -0.034 to -0.047 during 2001 to 2006, compared to -0.058 to -0.077 in the 2007 to 2010 period. This paper also examines whether there are regional differences in the short-run price elasticity of gasoline demand in the United States. However, there appears to only be modest variation in price elasticity values across regions.

    Economic factors such as rising gasoline prices may contribute to the crash trends by shaping individuals' choices of transportation modalities. This study examines the relationship of gasoline prices with fatal and non-fatal motorcycle injuries. Data on fatal and non-fatal motorcycle injuries come from California's Statewide Integrated Traffic Records System for 2002-2011. Autoregressive integrated moving average (ARIMA) regressions were used to estimate the impact of inflation-adjusted gasoline price per gallon on trends of motorcycle injuries. Motorcycle fatalities and severe and minor injuries in California were highly correlated with increasing gasoline prices from 2002 to 2011 (r=0.76, 0.88 and 0.85, respectively). In 2008, the number of fatalities and injuries reached 13,457--a 34% increase since 2002, a time period in which inflation-adjusted gasoline prices increased about $0.30 per gallon every year. The majority of motorcycle riders involved in crashes were male (92.5%), middle-aged (46.2%) and non-Hispanic white (67.9%). Using ARIMA modelling, we estimated that rising gasoline prices resulted in an additional 800 fatalities and 10,290 injuries from 2002 to 2011 in California. Our findings suggest that increasing gasoline prices led to more motorcycle riders on the roads and, consequently, more injuries. Aside from mandatory helmet laws and their enforcement, other strategies may include raising risk awareness of motorcyclists and investment in public transportation as an alternative transportation modality to motorcycling. In addition, universally mandated training courses and strict licensing tests of riding skills should be emphasised to help reduce the motorcycle fatal and non-fatal injuries.

  11. Assessment of Gasoline Prices and its Predictive Power on U.S. Consumers' Retail Spending and Savings

    NASA Astrophysics Data System (ADS)

    Alvarado-Bonilla, Joel

    The rising costs of fuels and specifically gasoline pose an economic challenge to U.S. consumers. Thus, the specific problem considered in this study was a rise in gasoline prices can reduce consumer spending, disposable income, food service traffic, and spending on healthy food, medicines, or visits to the doctor. Aligned with the problem, the purpose of this quantitative multiple correlation study was to examine the economic aspects for a rise in gasoline prices to reduce the six elements in the problem. This study consisted of a correlational design based on a retrospective longitudinal analysis (RLA) to examine gasoline prices versus the economic indexes of: (a) Retail Spending and (b) personal savings (PS). The RLA consisted on historic archival public data from 1978 to 2015. This RLA involved two separate linear multiple regression analyses to measure gasoline price's predictive power (PP) on two indexes while controlling for Unemployment Rate (UR). In summary, regression Formula 1 revealed Gasoline Price had a significant 61.1% PP on Retail Spending. In contrast, Formula 2 had Gasoline Price not having a significant PP on PS. Formula 2 yielded UR with 38.8% PP on PS. Results were significant at p<.01. Gasoline Price's PP on Retail Spending means a spending link to retail items such as: food service traffic, healthy food, medicines, and consumer spending. The UR predictive power on PS was unexpected, but logical from an economic view. Also unexpected was Gasoline Price's non-predictive power on PS, which suggests Americans may not save money when gasoline prices drop. These results shed light on the link of gasoline and UR on U.S. consumer's economy through savings and spending, which can be useful for policy design on gasoline and fuels taxing and pricing. The results serve as a basis for future study on gasoline and economics.

    To investigate longitudinal associations between community-level gasoline price and physical activity (PA). In the Coronary Artery Risk Development in Young Adults study, 5115 black and white participants aged 18-30 at baseline 1985-86 were recruited from four U.S. cities (Birmingham, Chicago, Minneapolis and Oakland) and followed over time. We used data from 3 follow-up exams: 1992-93, 1995-96, and 2000-01, when the participants were located across 48 states. From questionnaire data, a total PA score was summarized in exercise units (EU) based on intensity and frequency of 13 PA categories. Using Geographic Information Systems, participants' residential locations were linked to county-level inflation-adjusted gasoline price data collected by the Council for Community & Economic Research. We used a random-effect longitudinal regression model to examine associations between time-varying gasoline price and time-varying PA, controlling for age, race, gender, baseline study center, and time-varying education, marital status, household income, county cost of living, county bus fare, census block-group poverty, and urbanicity. Holding all control variables constant, a 25-cent increase in inflation-adjusted gasoline price was significantly associated with an increase of 9.9 EU in total PA (95% CI: 0.8-19.1). Rising prices of gasoline may be associated with an unintended increase in leisure PA. Copyright © 2011 Elsevier Inc. All rights reserved.

  14. Decomposition of the price and income elasticities of the consumer demand for gasoline

    The authors specify and estimate a model of the short-run demand for gasoline which allows them to decompose a consumer's gasoline demand elasticities into miles-driven and driving-efficiency components. Their model is estimated using detailed household survey data which allows direct focus on the short run, holding both the household's automobile stock and demographic profile fixed. Among the most interesting results are: (1) The data allow interesting insights to be drawn into the interrelationship between these important variables and household behavior with respect to gasoline consumption, miles driven, and driving efficiency. (2) The gasoline demand behavior of one-car and multi-car households differ significantly from each other. Evaluated at overall sample means, one-car households have higher (in absolute value) price elasticites for gasoline, miles driven and fuel-efficiency demand. Conversely, multi-car households have higher (in absolute value) total expenditure elasticities for each category. (3) For both one-car and multi-car households, roughly 75% of the estimated price elasticity and roughly 80% of the estimated total-expenditure elasticity of gasoline demand stem from the miles-driven component. The estimated fuel-efficiency elasticities, though smaller than their standard errors, indicate that households respond to changes in prices and total-expenditure levels not only by changing the number of miles they drive, but also by changing the efficiency with which they drive them. 23 references, 3 tables.

  15. An empirical investigation of spatial differentiation and price floor regulations in retail markets for gasoline

    NASA Astrophysics Data System (ADS)

    Houde, Jean-Francois

    In the first essay of this dissertation, I study an empirical model of spatial competition. The main feature of my approach is to formally specify commuting paths as the "locations" of consumers in a Hotelling-type model of spatial competition. The main consequence of this location assumption is that the substitution patterns between stations depend in an intuitive way on the structure of the road network and the direction of traffic flows. The demand-side of the model is estimated by combining a model of traffic allocation with econometric techniques used to estimate models of demand for differentiated products (Berry, Levinsohn and Pakes (1995)). The estimated parameters are then used to evaluate the importance of commuting patterns in explaining the distribution of gasoline sales, and compare the economic predictions of the model with the standard home-location model. In the second and third essays, I examine empirically the effect of a price floor regulation on the dynamic and static equilibrium outcomes of the gasoline retail industry. In particular, in the second essay I study empirically the dynamic entry and exit decisions of gasoline stations, and measure the impact of a price floor on the continuation values of staying in the industry. In the third essay, I develop and estimate a static model of quantity competition subject to a price floor regulation. Both models are estimated using a rich panel dataset on the Quebec gasoline retail market before and after the implementation of a price floor regulation.

    Motor vehicle accidents are the leading cause of death among young adults. Although automobile fatalities have declined in recent years, motorcycle fatalities are rapidly increasing. The purpose of our research was to quantify the relationship between changing fuel prices and motorcycle fatalities. Our findings suggest that people increasingly rely on motorcycles to reduce their fuel costs in response to rising gasoline prices. We estimate that use of motorcycles and scooters instead of 4-wheeled vehicles results in over 1500 additional motorcycle fatalities annually for each dollar increase in gas prices. Motorcycle safety should receive more attention as a leading public health issue. PMID:19696374

    The Oak Ridge National Laboratory (ORNL) conducts process analysis and engineering evaluation studies for the Department of Energy to provide, on a consistent basis, technical and economic assessments of processes and systems for coal conversion and utilization. Such assessments permit better understanding of the relative technical and economic potential of these processes. The objective of the work described here was to provide an assessment of the technical feasibility, economic competitiveness, and environmental acceptability of selected indirect coal liquefaction processes on a uniform, consistent, and impartial basis. Particular emphasis is placed on production of methanol as a principal product or methanol production for conversion to gasoline. Potential uses for the methanol are combustion in peaking-type turbines or blending with gasoline to yield motor fuel. Conversion of methanol to gasoline is accomplished through the use of the Mobil methanol-to-gasoline (MTG) process. Under the guidance of ORNL, Fluor Engineers and Constructors, Houston Division, prepared four conceptual process designs for indirect conversion of a Western subbituminous coal to either methanol or gasoline. The conceptual designs are based on the use of consistent technology for the core of the plant (gasification through methanol synthesis) with additional processing as necessary for production of different liquid products of interest. The bases for the conceptual designs are given. The case designations are: methanol production for turbine-grade fuel; methanol production for gasoline blending; gasoline production with coproduction of SNG; and gasoline production maximized.

    This study examined the association between gasoline prices and hospitalizations for motorcycle and nonmotorcycle motor vehicle crash (MVC) injuries. Data on inpatient hospitalizations were obtained from the 2001 to 2010 Nationwide Inpatient Sample. Panel feasible generalized least squares models were used to estimate the effects of monthly inflation-adjusted gasoline prices on hospitalization rates for MVC injuries and to predict the impact of increasing gasoline taxes. On the basis of the available data, a $1.00 increase in the gasoline tax was associated with an estimated 8348 fewer annual hospitalizations for nonmotorcycle MVC injuries, and reduced hospital costs by $143 million. However, the increase in the gasoline tax was also associated with an estimated 3574 more annual hospitalizations for motorcycle crash injuries, and extended hospital costs by $73 million. This analysis of some existing data suggest that the increased utilization and costs of hospitalization from motorcycle crash injuries associated with an increase in the price of gasoline are likely to substantially offset reductions in nonmotorcycle MVC injuries. A policy decision to increase the gasoline tax could improve traffic safety if the increased tax is paired with public health interventions to improve motorcycle safety.

    Motorcyclists have been reported to be more likely to die in a motor vehicle collision (MVC) than automobile occupants. With the recent increase in the pump price of gasoline, it has been reported that people are switching to motorcycles as main modes of transportation. This study evaluated the association between motor vehicle collision-related injury and mortality rates and increases in gasoline prices for occupants of automobiles and riders of motorcycles. There were an estimated 1,270,512 motorcycle MVC and 238,390,853 automobile MVC involved occupants in the U.S. from 1992 to 2007. Higher gasoline prices were associated with increased motorcycle-related injuries and deaths; however, this association no longer remained after accounting for changes in the number of registered vehicles. The current study observed that, while the number of injuries and fatalities in motorcycle-related MVCs increase with increasing gasoline price, rates remained largely unchanged. This suggests that the observed increase in motorcycle-related injuries and fatalities with increasing gasoline price is more a factor of the number of motorcycles on the road rather than operator characteristics.

  1. Motor gasoline assessment, Spring 1997

    SciTech Connect

    1997-07-01

    The springs of 1996 and 1997 provide an excellent example of contrasting gasoline market dynamics. In spring 1996, tightening crude oil markets pushed up gasoline prices sharply, adding to the normal seasonal gasoline price increases; however, in spring 1997, crude oil markets loosened and crude oil prices fell, bringing gasoline prices down. This pattern was followed throughout the country except in California. As a result of its unique reformulated gasoline, California prices began to vary significantly from the rest of the country in 1996 and continued to exhibit distinct variations in 1997. In addition to the price contrasts between 1996 and 1997, changes occurred in the way in which gasoline markets were supplied. Low stocks, high refinery utilizations, and high imports persisted through 1996 into summer 1997, but these factors seem to have had little impact on gasoline price spreads relative to average spread.

  4. Sample selection and spatial models of housing price indexes, and, A disequilibrium analysis of the U.S. gasoline market using panel data

    NASA Astrophysics Data System (ADS)

    Hu, Haixin

    This dissertation consists of two parts. The first part studies the sample selection and spatial models of housing price index using transaction data on detached single-family houses of two California metropolitan areas from 1990 through 2008. House prices are often spatially correlated due to shared amenities, or when the properties are viewed as close substitutes in a housing submarket. There have been many studies that address spatial correlation in the context of housing markets. However, none has used spatial models to construct housing price indexes at zip code level for the entire time period analyzed in this dissertation to the best of my knowledge. In this paper, I study a first-order autoregressive spatial model with four different weighing matrix schemes. Four sets of housing price indexes are constructed accordingly. Gatzlaff and Haurin (1997, 1998) study the sample selection problem in housing index by using Heckman's two-step method. This method, however, is generally inefficient and can cause multicollinearity problem. Also, it requires data on unsold houses in order to carry out the first-step probit regression. Maximum likelihood (ML) method can be used to estimate a truncated incidental model which allows one to correct for sample selection based on transaction data only. However, convergence problem is very prevalent in practice. In this paper I adopt Lewbel's (2007) sample selection correction method which does not require one to model or estimate the selection model, except for some very general assumptions. I then extend this method to correct for spatial correlation. In the second part, I analyze the U.S. gasoline market with a disequilibrium model that allows lagged-latent variables, endogenous prices, and panel data with fixed effects. Most existing studies (see the survey of Espey, 1998, Energy Economics) of the gasoline market assume equilibrium. In practice, however, prices do not always adjust fast enough to clear the market

    With the proliferation of statewide energy savings targets and other policies favorable to energy efficiency, savings from utility customer-funded energy efficiency programs could rise to offset much of annual load growth by 2025 (Barbose et al 2013). For these increased savings to occur, however, nearly all of these programs must pass screening for cost effectiveness. Some program administrators and state regulators are finding that conventional analyses, which only consider a narrow set of energy-savings related efficiency program benefits, are now resulting in some natural gas efficiency programs failing their cost-effectiveness criteria in the new low natural gas price environment. Regulators are considering whether to scale back or terminate gas portfolios in at least four states (WA, OR, ID, NM) because of cost-effectiveness concerns. Stakeholders in several regions of the country have asked LBNL to help assess alternatives to reducing the pursuit of energy savings in their regions. We address these requests by producing two working papers: one exploring cost-effectiveness screening policy implications of low to moderate natural gas prices, and a second assessing some of the values that policymakers may take into account in weighing the pros and cons of ending natural gas efficiency programs. In this policy brief, we lay out the challenges that low gas prices pose for cost effectiveness of an electric-gas efficiency program and portfolio. We then quantify options available to regulators and administrators who want to evaluate the tradeoffs among multiple policy objectives. A multi-measure, residential energy upgrade program in the Midwest is used as a lens to explore the implications of common and emerging cost-effectiveness policies in the context of low prices for natural gas. We illustrate the results across a range of cost-effectiveness screening options, including different discount rates, levels of test application, various benefit-cost tests, and the

    The effects of Federal refined-product price controls upon the price of motor gasoline in the United States through 1977 are examined. A comparison of domestic and foreign gasoline prices is made, based on the prices of products actually moving in international trade. There is also an effort to ascribe US/foreign market price differentials to identifiable cost factors. Primary emphasis is on price comparisons at the wholesale level, although some retail comparisons are presented. The study also examines the extent to which product price controls are binding, and attempts to estimate what the price of motor gasoline would have been in the absence of controls. The time period under consideration is from 1969 through 1977, with primary focus on price relationships in 1970-1971 (just before US controls) and 1976-1977. The foreign-domestic comparisons are made with respect to four major US cities, namely, Boston, New York, New Orleans, and Los Angeles. 20 figures, 14 tables.

  12. Misunderstood markets: The case of California gasoline

    NASA Astrophysics Data System (ADS)

    Thompson, Jennifer Ruth

    In 1996, the California Air Resources Board (CARB) implemented a new benchmark for cleaner burning gasoline that is unique to California. Since then, government officials have often expressed concern that the uniqueness of petroleum products in California segregates the industry, allowing for gasoline prices in the State that are too high and too volatile. The growing concern about the segmentation of the California markets lends itself to analysis of spatial pricing. Spatial price spreads of wholesale gasoline within the state exhibit some characteristics that seem, on the surface, inconsistent with spatial price theory. Particularly, some spatial price spreads of wholesale gasoline appear larger than accepted transportation rates and other spreads are negative, giving a price signal for transportation against the physical flow of product. Both characteristics suggest some limitation in the arbitrage process. Proprietary data, consisting of daily product prices for the years 2000 through 2002, disaggregated by company, product, grade, and location is used to examine more closely spatial price patterns. My discussion of institutional and physical infrastructure outlines two features of the industry that limit, but do not prohibit, arbitrage. First, a look into branding and wholesale contracting shows that contract terms, specifically branding agreements, reduces the price-responsiveness of would-be arbitrageurs. Second, review of maps and documents illustrating the layout of physical infrastructure, namely petroleum pipelines, confirms the existence of some connections among markets. My analysis of the day-of-the-week effects on wholesale prices demonstrates how the logistics of the use of transportation infrastructure affect market prices. Further examination of spatial price relationships shows that diesel prices follow closely the Augmented Law of One Price (ALOP), and that branding agreements cause gasoline prices to deviate substantially ALOP.

    The price difference between US conventional and reformulated gasolines is expected to be 3.1[cents]/gal higher, less than the 4[cents]/gal difference indicated in May by the New York Mercantile Exchange. The difference will be set by the central Atlantic and New England areas, which Bonner Moore projects to be significantly short on reformulated gasoline and long on conventional gasoline. Bonner Moore consultants, in an unpublished report, say refiners in the central Atlantic will not be able to economically convert much more than 70% of their gasoline output to reformulated gasoline. As a result, gasoline movements through the pipeline system supplying Petroleum Administration for Defense District (PADD) 1-the US East Coast-will have to increase to deliver reformulated gasoline produced on the Gulf Coast to New England and the Central Atlantic region. The paper discusses production costs, processing options, price differential, compliance, and benefits from averaging both oxygen and benzene parameters.

    This dissertation examines competition in the retail gasoline industry. The first chapter highlights the importance of gasoline in modern society, introduces my work, and places it in the context of the existing academic literature. The second chapter details the institutional structure and profitability of the industry. The vast majority of retail gasoline stations are not directly owned and operated by major oil companies. Instead, most stations are set up under other contractual relationships: lessee-dealer, open-dealer, jobber-owned-and-operated, and independent. Gasoline retailers make relatively low profits, as is the case in many other retail industries, and are substantially less profitable than major oil companies. Gas stations also make less money when retail prices are climbing than when they are falling. As prices rise, total station profits are near zero or negative. When retail prices are constant or falling, retailers can make positive profits. The third chapter describes the entry of big-box stores into the retail gasoline industry over the last decade. The growth of such large retailers, in all markets, has led to a great deal of controversy as smaller competitors with long-term ties to the local community have become less common. I estimate the price impact that big-box stores have on traditional gasoline retailers using cross-sectional data in two geographically diverse cities. I also examine changes in pricing following the entry of The Home Depot into a local retail gasoline market. The results show that big-box stores place statistically and economically significant downward pressure on the prices of nearby gas stations, offering a measure of the impact of the entry of a big-box store. Chapter 4 examines the nature of price competition in markets where some competing retailers sell the same brand. The price effect of having more retailers selling the same brand is theoretically unclear. High brand diversity could give individual retailers

    Increasingly sophisticated gasoline technology now makes gasoline more expensive to produce, but cheaper to buy, than in the early part of the century. Gasoline technology has kept pace with the sophistication of engines in the effort to find ways to produce gasoline of sufficient octane without using lead.

Other problems will develop as computerized fuel controls and small, high horsepower engines enter the market, but the gasoline refiners will be working on their solutions.

    This report documents the National Renewable Energy Laboratory's (NREL's) assessment of the feasibility of making gasoline via the methanol-to-gasoline route using syngas from a 2,000 dry metric tonne/day (2,205 U.S. ton/day) biomass-fed facility. A new technoeconomic model was developed in Aspen Plus for this study, based on the model developed for NREL's thermochemical ethanol design report (Phillips et al. 2007). The necessary process changes were incorporated into a biomass-to-gasoline model using a methanol synthesis operation followed by conversion, upgrading, and finishing to gasoline. Using a methodology similar to that used in previous NREL design reports and a feedstock cost of $50.70/dry ton ($55.89/dry metric tonne), the estimated plant gate price is $16.60/MMBtu ($15.73/GJ) (U.S. $2007) for gasoline and liquefied petroleum gas (LPG) produced from biomass via gasification of wood, methanol synthesis, and the methanol-to-gasoline process. The corresponding unit prices for gasoline and LPG are $1.95/gallon ($0.52/liter) and $1.53/gallon ($0.40/liter) with yields of 55.1 and 9.3 gallons per U.S. ton of dry biomass (229.9 and 38.8 liters per metric tonne of dry biomass), respectively.

    A detailed study was made of the feasibility of producing approximately 12,000 barrels per day of gasoline from high sulfur Illinois coal. The project was to be based on indirect liquefaction of coal by producing methanol and converting the methanol to raw gasoline. The plant design was based on proven processes: including atmospheric Koppers-Totzek type coal gasification, Rectisol gas purification, Claus and Scot sulfur recovery, and ICI low pressure methanol synthesis, all of which have been used in large commercial plants; and the fixed bed Mobil MTG process, which has been demonstrated in a four barrel per day pilot plant, to convert methanol into gasoline. The plant was designed to meet all federal and state regulations pertaining to environmental protection. The plant would cost approximately $1.27 billion (1981 dollars). Annual operating costs would total $243 million (1981 dollars). It has been determined that the project would not be viable in the present economic environment. Using 1981 dollars, and recognizing the present average refinery selling price in the mid-West of gasoline produced from crude oil is about $42 per barrel, the following gasoline prices have been calculated. For example, if the project were financed entirely by equity funds, then the selling price of gasoline would have to be $122 per barrel in a moderately inflating general economy in order to obtain a rate of return of 10% on the investment. The selling price would be lowered to $106 per barrel if no inflation is assumed. If 75% of the project were financed by debt at 16% interest, and the real price of coal and gasoline increased by 3% more than the general inflation rate, the selling price in 1981 dollars would be $76 per barrel in a moderately inflating economy. As the real price of gasoline increases in the future, this project and the related economics should be reviewed.

  3. Ethanol Demand in United States Gasoline Production

    SciTech Connect

    Hadder, G.R.

    1998-11-24

    The Oak Ridge National Laboratory (OWL) Refinery Yield Model (RYM) has been used to estimate the demand for ethanol in U.S. gasoline production in year 2010. Study cases examine ethanol demand with variations in world oil price, cost of competing oxygenate, ethanol value, and gasoline specifications. For combined-regions outside California summer ethanol demand is dominated by conventional gasoline (CG) because the premised share of reformulated gasoline (RFG) production is relatively low and because CG offers greater flexibility for blending high vapor pressure components like ethanol. Vapor pressure advantages disappear for winter CG, but total ethanol used in winter RFG remains low because of the low RFG production share. In California, relatively less ethanol is used in CG because the RFG production share is very high. During the winter in California, there is a significant increase in use of ethanol in RFG, as ethanol displaces lower-vapor-pressure ethers. Estimated U.S. ethanol demand is a function of the refiner value of ethanol. For example, ethanol demand for reference conditions in year 2010 is 2 billion gallons per year (BGY) at a refiner value of $1.00 per gallon (1996 dollars), and 9 BGY at a refiner value of $0.60 per gallon. Ethanol demand could be increased with higher oil prices, or by changes in gasoline specifications for oxygen content, sulfur content, emissions of volatile organic compounds (VOCS), and octane numbers.

    1994-12-31

    This paper presents econometric estimates of motor gasoline demand in eleven developing countries of Asia. The price and GDP per capita elasticities are estimated for each country separately, and for several pooled combinations of the countries. The estimated elasticities for the Asian countries are compared with those of the OECD countries. Generally, one finds that the OECD countries have GDP elasticities that are smaller, and price elasticities that are larger (in absolute value). The price elasticities for the low-income Asian countries are more inelastic than for the middle-income Asian countries, and the GDP elasticities are generally more elastic. 13 refs., 6 tabs.

    In recent years it has been clear that the reserves of oil, from which petrol is refined, are becoming limited. In order to conserve these stocks of oil, and to minimize motoring costs as the price of dwindling oil resources escalates, it's obviously desirable to improve the thermal efficiency of the spark ignition engine. There are also obvious benefits to be obtained from making spark ignition engines run efficiently on alternative fuel, (non-crude based fuel). It has been claimed that hydrogen is an ideal fuel for the internal combustion engine it certainly causes little pollution, but is difficult to store, high in price, and difficult to burn efficiently in the engine without it knocking and backfiring. These problems arise because of the very wide flammability limits and the very high flame velocity of hydrogen. Alcohols used an additive or substitute for gasoline could immediately help to solve both energy and pollution problems. An experimental tests were carried out at Mansoura University Laboratories using a small single cylinder SIE, fully instrumented to measure the engine performance. The engine was fueled with pure methonol, pure ethonol, gasoline methanol blends and gasaline ethanol blends. The results showed that in principle, from kechnological aspects it's possible to use alcohols as a gasoline extender or as alcohol's gasoline, blends for automobiles. With regard to energy consumptions alcohols and alcohols gasoline blends lead to interesting results. The fuel economy benefits of using alcohols gasoline blends was found to be interesting in the part throltle operation.

    Shelton, E M; Whisman, M L; Woodward, P W

    1982-06-01

    Trends in motor gasolines for the years of 1942 through 1981 have been evaluated based upon data contained in surveys that have been prepared and published by the Bartlesville Energy Technology Center (BETC). These surveys have been published twice annually since 1935 describing the properties of motor gasolines from throughout the country. The surveys have been conducted in cooperation with the American Petroleum Institute (API) since 1948. Various companies from throughout the country obtain samples from retail outlets, analyze the samples by the American Society for Testing and Materials (ASTM) procedures, and report data to the Bartlesville center for compilation, tabulation, calculation, analysis and publication. A typical motor gasoline report covers 2400 samples from service stations throughout the country representing some 48 companies that manufacture and supply gasoline. The reports include trend charts, octane plots, and tables of test results from about a dozen different tests. From these data in 77 semiannual surveys, a summary report has thus been assembled that shows trends in motor gasolines throughout the entire era of winter 1942 to 1943 to the present. Trends of physical properties including octane numbers, antiknock ratings, distillation temperatures, Reid vapor pressure, sulfur and lead content are tabulated, plotted and discussed in the current report. Also included are trend effects of technological advances and the interactions of engine design, societal and political events and prices upon motor gasoline evolution during the 40 year period.

    The Midwestern Greenhouse Gas Reduction Acccord, or Midwestern Greenhouse gas Accord (MGA), is a regional agreement by governors of the states in the US Midwest and one Canadian province to reduce greenhouse gas emissions to combat climate change. Signatories to the accord include the US states of Minnesota, Wisconsin, Illinois, Indiana, Iowa, Michigan, Kansas, Ohio and South Dakota, and the Canadian Province of Manitoba. The accord, signed on November 15, 2007, established the Midwestern Greenhouse Gas Reduction Program, which aims to: establish greenhouse gas reduction targets and timeframes consistent with MGA member states' targets; develop a market-based and multi-sector cap-and-trade mechanism to help achieve those reduction targets; establish a system to enable tracking, management, and crediting for entities that reduce greenhouse gas emissions; and develop and implement additional steps as needed to achieve the reduction targets, such as a low-carbon fuel standards and regional incentives and funding mechanisms. The GHG registry will be managed by the Climate Registry, which manages the registry for other US state schemes. One of the first actions was to convene an Energy Security under Climate Stewardship Platform to guide future development of the Midwest's energy economy.

    Chemical burns and pulmonary complications are the most common problems encountered in the patient immersed in gasoline. Our patient demonstrated a 46-percent total-body-surface area, partial-thickness chemical burn. Although he did not develop bronchitis or pneumonitis, he did display persistent atelectasis, laryngeal edema, and subsequent upper airway obstruction. This had not previously been reported in gasoline inhalation injuries. Hydrocarbon hepatitis secondary to the vascular endothelial damage is apparently a reversible lesion with no reported long-term sequelae. Gasoline immersion injuries may be a series multisystem injury and require the burn surgeon to take a multisystem approach to its diagnosis and treatment.

    The final rules adopted by the President for a Standby Gasoline Rationing Plan are presented. The plan provides that eligibility for ration allotments will be determined primarily on the basis of motor vehicle registrations, taking into account historical differences in the use of gasoline among states. The regulations also provide authority for supplemental allotments to firms so that their allotment will equal a specified percentage of gasoline use during a base period. Priority classifications, i.e., agriculture, defense, etc., are established to assure adequate gasoline supplies for designated essential services. Ration rights must be provided by end-users to their suppliers for each gallon sold. DOE will regulate the distribution of gasoline at the wholesale level according to the transfer by suppliers of redeemed ration rights and the gasoline allocation regulations. Ration rights are transferable. A ration banking system is created to facilitate transfers of ration rights. Each state will be provided with a reserve of ration rights to provide for hardship needs and to alleviate inequities. (DC)

    Gasoline contains large numbers of dangerous and cancer-causing chemicals such as benzene, butadiene, toluene, ethylbenzene, xylene, trimethyl pentane, methyltertbutylether (MTBE) and many others. For the U.S. alone approximately 140 billion gallons of gasoline were consumed in 1989. An increase in only ten cents per gallon in price of gasoline generates 14 billion dollars in extra profit per year for oil industry cartel. Laboratory animals exposed to gasoline developed cancers in different tissues and organs. A number of epidemiological studies in humans provide evidence of increased cancer risk of leukemia, kidney, liver, brain, lymphosarcoma, lymphatic tissue pancreas and other tissues and organs.

  18. Essays on price dynamics and consumer search

    NASA Astrophysics Data System (ADS)

    Lewis, Matthew Stephen

    It has been documented that retail gasoline prices respond more quickly to increases in wholesale price than to decreases. However, there is very little theoretical or empirical evidence identifying the market characteristics responsible for this behavior. Chapter 2 presents a new theoretical model of asymmetric adjustment that empirically matches observed retail gasoline price behavior better than previously suggested explanations. I develop a "reference price" consumer search model that assumes consumers' expectations of prices are based on prices observed during previous purchases. The model predicts that consumers search less when prices are falling. This reduced search results in higher profit margins and therefore causes a slower price response to cost decreases than to cost increases. Chapter 3 discusses the robustness of some of the important assumptions of the reference price search model, and describes the effects of altering these assumptions. Chapter 4 develops testable implications that distinguish my model from two alternative explanations of asymmetric adjustment. The first is a model in which firms temporarily collude using past prices as a focal price. The second theory suggests that increases in wholesale cost volatility reduce consumer search behavior. Using a panel of gas station prices, I estimate the response pattern of prices to a change in costs. Estimates are consistent with the predictions of the reference price search model and contradict the previously suggested explanations of asymmetric price adjustment. Chapter 5 examines the empirical fact that price response varies depending on the current level of profit margins. This fact is contrasted with the common empirical observation that response differs based on the direction of the change in cost. I go on to document that this relationship between price response and margins is observed in gasoline markets across the country.

    Many econometric studies of gasoline demand have been conducted over the years when fuel prices where high and concerns about energy conservation and security of supply were prominent. Studies were motivated by interest in gasoline consumers` sensitivity to fuel price changes, for the insight this might give in explaining cross country differences in gas consumption and driving and in predicting the impact of fuel tax changes on driving, fuel consumption and government revenue collections. The author used meta-analysis to determine if there are factors that systematically affect price and income elasticity estimates in studies of gasoline demand in the United States.

    Although gasoline blending streams exhibit widely varying sulfur concentrations, significant quantities of low-sulfur motor gasoline cannot be manufactured by reallocation of existing components without substantial sacrifices in the useful properties of the remaining fuels having normal sulfur levels. To meet the anticipated demand for low-sulfur unleaded gasoline which may be required for catalyst-equipped automobiles it will be necessary to install process equipment based on known hydrotreating technology. The effects which this construction program would exert on the activities, abilities and needs of one petroleum refiner are sketched for two degrees of sulfur removal. The impacts of installing the process facilities which would be necessary are discussed in terms of time requirements, capital needs, and added energy expenditures. PMID:1157782

    ARCO announced plans on August 15 to introduce a new low-emission regular gasoline into the Southern California market September 1 that will significantly reduce air pollution from pre-1975 cars and pre-1980 trucks. The new environmentally formulated blend, called EC-1, will replace ARCO's leaded regular gasoline. ARCO's price to its dealers will be the same as it was for leaded regular. EC (Emission Control) -1 is the first phase of ARCO's plan to help make even greater reductions in vehicular air pollution in Southern California during the next decade. The unique lead-free gasoline is for use only in vehicles not equipped with catalytic converters which now operate on leaded regular gasoline. ARCO's tests, shared with the South Coast Air Quality Management District (SCAQMD) and the California Air Resources Board (ARB), show that is all current users of leaded regular gasoline in Southern California switched to the new gasoline about 350 tons of pollutants would be removed from the air each day. It is uniquely formulated to help Southern Californians meet federal and state ambient air quality standards on carbon monoxide, oxides of nitrogen, ozone, and particular matter without any reduction in vehicular performance or engine modification.

  11. Assessing the Macroeconomic Importance of Gasoline and Vehicle Spending

    Vector error correction (VEC) was used to test the importance of a theoretical causal chain from transportation fuel cost to vehicle sales to macroeconomic activity. Real transportation fuel cost was broken into two cost components: real gasoline price (rpgas) and real personal consumption of gasoline and other goods (gas). Real personal consumption expenditure on vehicles (RMVE) represented vehicle sales. Real gross domestic product (rGDP) was used as the measure of macroeconomic activity. The VEC estimates used quarterly data from the third quarter of 1952 to the first quarter of 2014. Controlling for the financial causes of the recent Great Recession, real homeowners’ equity (equity) and real credit market instruments liability (real consumer debt, rcmdebt) were included. Results supported the primary hypothesis of the research, but also introduced evidence that another financial path through equity is important, and that use of the existing fleet of vehicles (not just sales of vehicles) is an important transport-related contributor to macroeconomic activity. Consumer debt reduction is estimated to be a powerful short-run force reducing vehicle sales. Findings are interpreted in the context of the recent Greene, Lee, and Hopson (2012) (hereafter GLH) estimation of the magnitude of three distinct macroeconomic damage effects that result from dependence on imported oil, the price of which is manipulated by the Organization of Petroleum Exporting Countries (OPEC). The three negative macroeconomic impacts are due to (1) dislocation (positive oil price shock), (2) high oil price levels, and (3) a high value of the quantity of oil imports times an oil price delta (cartel price less competitive price). The third of these is the wealth effect. The VEC model addresses the first two, but the software output from the model (impulse response plots) does not isolate them. Nearly all prior statistical tests in the literature have used vector autoregression (VAR) and

    NASA Technical Reports Server (NTRS)

    1979-01-01

    Gasoline is volatile and some of it evaporates during storage, giving off hydrocarbon vapor. Formerly, the vapor was vented into the atmosphere but anti-pollution regulations have precluded that practice in many localities, so oil companies and storage terminals are installing systems to recover hydrocarbon vapor. Recovery provides an energy conservation bonus in that most of the vapor can be reconverted to gasoline. Two such recovery systems are shown in the accompanying photographs (mid-photo at right and in the foreground below). They are actually two models of the same system, although.configured differently because they are customized to users' needs. They were developed and are being manufactured by Edwards Engineering Corporation, Pompton Plains, New Jersey. NASA technological information proved useful in development of the equipment.

    To reduce greenhouse gas emissions in the coming decades, many governments will have to reform their energy policies. These policies are difficult to measure with any precision. As a result, it is unclear whether progress has been made towards important energy policy reforms, such as reducing fossil fuel subsidies. We use new data to measure net taxes and subsidies for gasoline in almost all countries at the monthly level and find evidence of both progress and backsliding. From 2003 to 2015, gasoline taxes rose in 83 states but fell in 46 states. During the same period, the global mean gasoline tax fell by 13.3% due to faster consumption growth in countries with lower taxes. Our results suggest that global progress towards fossil fuel price reform has been mixed, and that many governments are failing to exploit one of the most cost-effective policy tools for limiting greenhouse gas emissions.

  5. The economics of gasoline subsidy cost reduction policy: Case study of Indonesia

    NASA Astrophysics Data System (ADS)

    Akimaya, Muhammad I.

    A gasoline subsidy distorts the gasoline market with the resulting inefficiencies and takes substantial revenues that arguably could be spent elsewhere with a better impact on economic growth. Governments with such subsidies are aware of their cost yet face difficulties in removing the policy because of strong resistance from the public. This thesis discusses in three essays the problem faced by the government in removing the gasoline subsidy and provides an alternative policy in reducing the subsidy cost applied to the case of Indonesia. In the first essay, we examine the decision-making process from the government's perspective that has an objective of generating savings to fund other programs while maintaining political power, and the influence that the general population has over the decision. Despite the immense literature on political power, there has yet to be any research that mathematically models the decision-making process of a government with influences from the general population. Under the benchmark scenario, the equilibrium strategy is to keep the subsidy intact. However, the results are found to be very sensitive to the magnitude of the shift in political power as well as the preferences of both the government and the people. In the second essay, we estimate the cross-price elasticity of regular gasoline with respect to premium gasoline price. The importance of such knowledge is to accurately determine the impact of fuel pricing policy that tends to have different rates of tax or subsidy depending on the grade of gasoline. Using data on the Mexican gasoline market, regular gasoline demand is estimated with an Autoregressive Distributed Lag (ARDL) model. Endogeneity of the price and structural break are also investigated. The cross-price elasticities between regular and premium gasoline is found to be -0.895, which confirms high substitutability among gasoline with different grades. In the third essay, we look at the unique case of Indonesia that

Gasoline is the primary transportation fuel in America. Nearly 98% of the 190 million vehicles in this country run on gasoline or diesel fuel. EC-1 Regular was designed for use in old cars without catalytic converters - the pre-1975 vehicles designed for using leaded fuel. EC-1 Regular cut pollution from those old cars in the Los Angeles Basin by 20%, equivalent to removing thousands of these cars from the road. The advantages of using EC-1 Regular gasoline are discussed.

I use data on fuel prices and sales in combination with my formulas and elasticity estimates to calculate the deadweight loss of fuel price subsidies in Ghana from 2009 to 2014. I show that the average efficiency cost of the gasoline and diesel price subsidies in Ghana is 0.8% of fuel price subsidy transfers. This result stresses the futility of basing subsidy reforms on economic efficiency losses, which are relatively small due to very inelastic energy demand, and the need for such reforms to be motivated by the poor-targeting of subsidies to low-income households and the impact of subsidies on government debt-financing.

    1983-06-29

    Since the Energy Detente January 27, 1983 speical price/tax report of petroleum-product markets around the world, several countries in the survey experienced domestic price changes, generally upward. In Peru, the government-controlled price for a gallon of regular leaded gasoline increased 83% during the period. However, when converted to a reference currency, much of Peru's price increase is offset when viewed in terms of US dollars: with devaluation of Peru's national currency of 25% since January, the price increase corresponds to only 37% in US dollars. In the case of Venezuela, a currency devaluation of over 100% since February reduced the price from US $0.26 per gallon for regular leaded gasoline to US $0.11 per gallon, the lowest price in the survey. The highest price is US $3.22 per gallon for regular leaded in South Korea. The world average retail price for regular leaded gasoline is US $1.73 per gallon (16 cents lower than in January this year). For premium (leaded, in all but four countries), the world average price is US $1.86, and the drop since January is also 16 cents per gallon. The lowest price for premium-grade gasoline is US $0.25 in Saudi Arabia (which has no regular grade); the highest in the survey is US $4.34 in South Korea. In this issue, the Energy Detente fuel price/tax series and principal industrial fuel prices are given for June 1983 for countries of the Western Hemisphere.

  11. Techno-economic Analysis for the Conversion of Lignocellulosic Biomass to Gasoline via the Methanol-to-Gasoline (MTG) Process

    SciTech Connect

    Jones, Susanne B.; Zhu, Yunhua

    2009-05-01

    Biomass is a renewable energy resource that can be converted into liquid fuel suitable for transportation applications. As a widely available biomass form, lignocellulosic biomass can have a major impact on domestic transportation fuel supplies and thus help meet the Energy Independence and Security Act renewable energy goals (U.S. Congress 2007). With gasification technology, biomass can be converted to gasoline via methanol synthesis and methanol-to-gasoline (MTG) technologies. Producing a gasoline product that is infrastructure ready has much potential. Although the MTG technology has been commercially demonstrated with natural gas conversion, combining MTG with biomass gasification has not been shown. Therefore, a techno-economic evaluation for a biomass MTG process based on currently available technology was developed to provide information about benefits and risks of this technology. The economic assumptions used in this report are consistent with previous U.S. Department of Energy Office of Biomass Programs techno-economic assessments. The feedstock is assumed to be wood chips at 2000 metric ton/day (dry basis). Two kinds of gasification technologies were evaluated: an indirectly-heated gasifier and a directly-heated oxygen-blown gasifier. The gasoline selling prices (2008 USD) excluding taxes were estimated to be $3.20/gallon and $3.68/gallon for indirectly-heated gasified and directly-heated. This suggests that a process based on existing technology is economic only when crude prices are above $100/bbl. However, improvements in syngas cleanup combined with consolidated gasoline synthesis can potentially reduce the capital cost. In addition, improved synthesis catalysts and reactor design may allow increased yield.

  14. Biofiltration of gasoline and ethanol-amended gasoline vapors.

    2012-01-01

    Assuming the projected increase in use of ethanol as a biofuel, the current study was conducted to compare the biofiltration efficiencies for plain and 25% ethanol-containing gasoline. Two biofilters were operated in a downflow mode for 7 months, one of them being compost-based whereas the other using a synthetic packing material, granulated tire rubber, inoculated with gasoline-degrading microorganisms. Inlet concentrations measured as total hydrocarbon (TH) ranged from 1.9 to 5.8 g m(-3) at a constant empty bed retention time of 6.84 min. Contrary to the expectations based on microbiological considerations, ethanol-amended gasoline was more readily biodegraded than plain hydrocarbons, with the respective steady state elimination capacities of 26-43 and 14-18 gTH m(-3) h(-1) for the compost biofilter. The efficiency of both biofilters significantly declined upon the application of higher loads of plain gasoline, yet immediately recovering when switched back to ethanol-blended gasoline. The unexpected effect of ethanol in promoting gasoline biodegradation was explained by increasing hydrocarbon partitioning into the aqueous phase, with mass transfer being rate limiting for the bulk of components. The tire rubber biofilter, after a long acclimation, surpassed the compost biofilter in performance, presumably due to the 'buffering' effect of this packing material increasing the accessibility of gasoline hydrocarbons to the biofilm. With improved substrate mass transfer, biodegradable hydrocarbons were removed in the tire rubber biofilter's first reactor stage, with most of the remaining poorly degradable smaller-size hydrocarbons being degraded in the second stage.

    Six Midwestern governors and a Canadian premier signed the Midwestern Greenhouse Gas Reduction Accord in November 2007. The governors agreed to begin the process of developing a market-based cap-and-trade program that would reduce GHG emissions (e.g., carbon dioxide, methane, nitrous oxide, hydro-fluorocarbons, perfluorocarbons, and sulfur hexafluoride) to meet reduction targets. Member jurisdictions include Illinois, Iowa, Kansas, Manitoba, Michigan, Minnesota, and Wisconsin. Observer jurisdictions - those who are participating in the program design, but will decide later whether to be full members-include Indiana, Ohio, Ontario, and South Dakota. To date, the advisory group has proposed target ranges for GHG emissions reductions of 15-25% below 2005 levels by 2020 and 60-80% by 2050. The following sectors are currently being considered for the cap-and-trade program: electricity generation and imports (power plants); industrial combustion sources (factories and other industrial facilities); and industrial process sources (to the extent credible measurement and monitoring protocols exist or can be developed prior to inclusion).

  16. Reformulated gasoline quality issues

    1995-11-01

    One year ago, a panel of industry experts were interviewed in the November/December 1994 issue of Fuel Reformulation (Vol. 4, No. 6). With the focus then and now on refinery investments, the panelists were asked to forecast which refining processes would grow in importance. It is apparent from their response, and from other articles and discussions throughout the year, that hydroprocessing and catalytic conversion processes are synergistic in the overall refinery design, with flexibility and process objectives varying on a unit-by-unit case. To an extent, future refinery investments in downstream petrochemicals, such as for paraxylene production, are based on available catalytic reforming feedstock. Just a importantly, hydroprocessing units (hydrotreating, hydrocracking) needed for clean fuel production (gasoline, diesel, aviation fuel), are heavily dependent on hydrogen production from the catalytic reformer. Catalytic reforming`s significant influence in the refinery hydrogen balance, as well as its status as a significant naphtha conversion route to higher-quality fuels, make this unit a high-priority issue for engineers and planners striving for flexibility.

    Prices of four low fat foods were reduced about 25% and prices of three high fat foods were increased about 10% to determine the impact on food purchases in a Midwestern suburban high school cafeteria to explore the impact of price on purchases. Low fat foods averaged about 13% of total sales. Sensitivity analysis was used to estimate that low fat foods would probably have averaged about 9% of total sales without the reduced price.

  18. Reducing US oil-import dependence: A tariff, subsidy, or gasoline tax

    Yuecel, M.K. ); Dahl, C. )

    1990-05-01

    Low oil prices and rising oil imports have caused growing concern about U.S. vulnerability to oil-supply shocks. The authors devise a measure of vulnerability and use it to compare three policies that have been proposed to reduce U.S. vulnerability to oil-supply disruptions: a 25% oil-import tariff, a $5-per-barrel subsidy to domestic oil producers, and an increase in the gasoline tax from 9 cents to 25 cents per gallon. They find that the tariff would make the United States less vulnerable to disruptions. By increasing both consumer and producer prices, the tariff lowers consumption while encouraging domestic production. The increased gasoline tax could either lower or raise vulnerability. If domestic supply is not very responsive to price changes, the gasoline tax increases vulnerability. If domestic supply is responsive to price changes, the gasoline tax reduces vulnerability. The subsidy encourages increased consumption and production, leading to a faster depletion of the resource base. Hence, the subsidy would make the United States more vulnerable to oil-supply shocks. 10 refs., 8 figs., 1 tab.

Both physical unit prices and prices per million Btu are included in STEPS. Major changes in STEPS data base for 1981 and 1982 are described. The most significant changes in procedures for the updates occur in the residential sector distillate series and the residential sector kerosene series. All physical unit and Btu prices are shown with three significant digits instead of with four significant digits as shown in the original documentation. Details of these and other changes are contained in this report, along with the updated data files. 31 references, 65 tables.

  19. Do biofuel blending mandates reduce gasoline consumption? Implications of state-level renewable fuel standards for energy security

    NASA Astrophysics Data System (ADS)

    Lim, Shinling

    In an effort to keep America's addiction to oil under control, federal and state governments have implemented a variety of policy measures including those that determine the composition of motor gasoline sold at the pump. Biofuel blending mandates known as Renewable Fuel Standards (RFS) are designed to reduce the amount of foreign crude oil needed to be imported as well as to boost the local ethanol and corn industry. Yet beyond looking at changes in gasoline prices associated with increased ethanol production, there have been no empirical studies that examine effects of state-level RFS implementation on gasoline consumption. I estimate a Generalized Least Squares model for the gasoline demand for the 1993 to 2010 period with state and time fixed effects controlling for RFS. States with active RFS are Minnesota, Hawaii, Missouri, Florida, Washington, and Oregon. I find that, despite the onset of federal biofuel mandates across states in 2007 and the lower energy content of blended gasoline, being in a state that has implemented RFS is associated with 1.5% decrease in gasoline consumption (including blended gasoline). This is encouraging evidence for efforts to lessen dependence on gasoline and has positive implications for energy security.

    The effect of high gasoline prices on tourism in the Midwest is confusing as some data show Americans finding new ways to express their right to freedom of mobility through shorter and less-expensive trips, while other data reveal no impact on travel behavior. Although the tourism patterns of out-of-state visitors during 1979-80 are based on statistics that are collected differently in each state, several major findings in this report are that (1) high prices affect vacation plans; (2) the upper Midwest states were especially hurt because of their remoteness; (3) new transportation modes are replacing cars as vacationers select single destinations; and (4) small, independent businesses have suffered the most. This report suggests ways to promote tourism in the immediate vicinity of recreation areas, and recommends state promotional efforts that will taken advantage of new travel trends. 29 references, 4 tables.

  3. Evaporation characteristics of ETBE-blended gasoline.

    To reduce greenhouse gas emissions, which contribute to global warming, production of gasoline blended with ethyl tert-buthyl ether (ETBE) is increasing annually. The flash point of ETBE is higher than that of gasoline, and blending ETBE into gasoline will change the flash point and the vapor pressure. Therefore, it is expected that the fire hazard caused by ETBE-blended gasoline would differ from that caused by normal gasoline. The aim of this study was to acquire the knowledge required for estimating the fire hazard of ETBE-blended gasoline. Supposing that ETBE-blended gasoline was a two-component mixture of gasoline and ETBE, we developed a prediction model that describes the vapor pressure and flash point of ETBE-blended gasoline in an arbitrary ETBE blending ratio. We chose 8-component hydrocarbon mixture as a model gasoline, and defined the relation between molar mass of gasoline and mass loss fraction. We measured the changes in the vapor pressure and flash point of gasoline by blending ETBE and evaporation, and compared the predicted values with the measured values in order to verify the prediction model. The calculated values of vapor pressures and flash points corresponded well to the measured values. Thus, we confirmed that the change in the evaporation characteristics of ETBE-blended gasoline by evaporation could be predicted by the proposed model. Furthermore, the vapor pressure constants of ETBE-blended gasoline were obtained by the model, and then the distillation curves were developed. Copyright © 2015 Elsevier B.V. All rights reserved.

  4. Effects of different contractual arrangements: the case of retail gasoline markets

    Barron, J.M.; Umbeck, J.R.

    1984-10-01

    The change in the contractual arrangement at a gasoline station from a refiner-controlled to a franchise operation implies different incentives for the individual who sets prices and determines hours, but reflects no change in the product nor the market environment. The outcome can lead to higher prices and reduced hours at the station affected. The divorcement experience in Maryland illustrates how change can be imposed by the legal system. Average self-service and full-serve prices rose, and hours of operation fell relative to those of competitors even though refiner operations that were forced to franchise had previously had prices below the competition. The evidence of an effect on the prices and hours of competitors is less convincing. 16 references, 2 tables.

We embed the test in a discrete-choice model of product quality choice and estimate the model using panel microdata on gasoline purchases. We find that when gasoline prices rise consumers substitute to lower octane gasoline, to an extent that cannot be explained by income effects. Across a wide range of specifications, we consistently reject the null hypothesis that households treat "gas money" as fungible with other income. We compare the empirical fit of three psychological models of decision-making. A simple model of category budgeting fits the data well, with models of loss aversion and salience both capturing important features of the time series.

    The commercial availability and use of good quality gasolines are essential for the operation of high-technology automobiles without adverse effects on driveability and emissions. Some current and future fuel requirements for GM vehicles are addressed with a focus on certain trends in fuel composition and properties which are of importance or concern at this time. Examples include the contribution of elevated gasoline volatility to increased evaporative emissions, the compatibility of GM engines with gasolines blended with certain alcohols, and the need for gasolines without contaminants and with sufficient additives, such as detergents to keep port fuel injection systems clean.

    As greater amounts of US western coal is burned by many eastern and south-eastern power plants located along the Ohio River and its tributaries, Midwestern coal transload facilities are playing an ever growing role in the nation's coal transportation system by moving traffic off clogged rail lines onto barges on inland rivers. The article describes operations by three mid-western ports - American Electric Power's (AEP) Cook Terminal in Metropolis, IL; Kinder-Morgan's Cora Terminal in Cora, IL; and Kinder-Morgan's Grand Rivers Terminal near Paducah, KY. Together these terminals transferred more than 30 m tons onto barges in 2006. 5 figs.

  18. The differences in welfare loss and greenhouse gas emission reductions across socioeconomic groups in the United States from a Pigouvian tax on gasoline

    1995-12-31

    Considered are the welfare consequences of a Pigouvian tax, the goal of which, is to affect shifts in gasoline consumption, vehicle miles traveled, and ultimately, greenhouse gas emissions. Due to simultaneous choices made by a household during the production and consumption of gasoline-powered transportation services, some of the consumer surplus losses from an increase in the price of gasoline may be ameliorated through efficiency gains, even as the goals of the tax are being realized. Conjunct to this, it is shown that neither changes in efficiency, welfare losses, nor the associated reductions in greenhouse gas emissions are distributed equally across socioeconomic groups.

    Cellulosic and woody biomass can be directly converted to hydrocarbon gasoline and diesel blending components through the use of integrated hydropyrolysis plus hydroconversion (IH2). The IH2 gasoline and diesel blending components are fully compatible with petroleum based gasoline and diesel, contain less than 1% oxygen and have less than 1 total acid number (TAN). The IH2 gasoline is high quality and very close to a drop in fuel. The DOE funding enabled rapid development of the IH2 technology from initial proof-of-principle experiments through continuous testing in a 50 kg/day pilot plant. As part of this project, engineering work on IH2 has also been completed to design a 1 ton/day demonstration unit and a commercial-scale 2000 ton/day IH2 unit. These studies show when using IH2 technology, biomass can be converted directly to transportation quality fuel blending components for the same capital cost required for pyrolysis alone, and a fraction of the cost of pyrolysis plus upgrading of pyrolysis oil. Technoeconomic work for IH2 and lifecycle analysis (LCA) work has also been completed as part of this DOE study and shows IH2 technology can convert biomass to gasoline and diesel blending components for less than $2.00/gallon with greater than 90% reduction in greenhouse gas emissions. As a result of the work completed in this DOE project, a joint development agreement was reached with CRI Catalyst Company to license the IH2 technology. Further larger-scale, continuous testing of IH2 will be required to fully demonstrate the technology, and funding for this is recommended. The IH2 biomass conversion technology would reduce U.S. dependence on foreign oil, reduce the price of transportation fuels, and significantly lower greenhouse gas (GHG) emissions. It is a breakthrough for the widespread conversion of biomass to transportation fuels.

    The feasibility of adopting alternative standards for reformulated gasoline (RFG) in New York State has been studied for the New York State Energy Research and Development Authority (the Energy Authority). In addition to Federal RFG (EPA 1) and EPA II, California Air Resources Board RFG (CARB 2) and a modified Federal low sulfur RFG (LS-EPA II) were investigated. The effects of these alternative RFGs on petroleum refinery gasoline production costs, gasoline distribution costs, New York State air quality and the New York State economy were considered. New York has already adopted the California low emission vehicle (LEV) and other emission control programs that will affect vehicles and maintenance. From 1998 to 2012 without the introduction of any type of RFG, these programs are estimated to reduce New York State mobile source summer emissions by 341 tons per day (or 40%) of non-methane hydrocarbons (NMHC) and by 292 tons per day (or 28%) of nitrogen oxides (NO{sub x}), and to reduce winter emissions of carbon monoxide (CO) by 3,072 tons per day (or 39%). By 2012, the planned imposition of Federal RFG will produce further reductions (percent of 1998 levels) of 10 %, 4 % and 11%, respectively, for NMHC, NO{sub x} and CO. If New York State goes beyond EPA II and adopts CARB 2 specifications, further reductions achieved in 2012 are estimated to be very small, equaling 2% or less of 1998 levels of NMHC and NO{sub x} emissions, while CO emissions would actually increase by about 2%. When compared to EPA II over the same time frame, LS-EPA II would produce negligible (less than 1%) reductions in each of the above emissions categories.

    A National Fuels Surveillance Network has been established to collect gasoline and other fuels through the 10 regional offices of the Environmental Protection Agency. Physical, chemical, and trace element analytical determinations are made on the collected fuel samples to detect components which may present an air pollution hazard or poison exhaust catalytic control devices. A summary of trace elemental constituents in over 50 gasoline samples and 18 commercially marketed consumer purchased gasoline additives is presented. Quantities of Mn, Ni, Cr, Zn, Cu, Fe, Sb, B, Mg, Pb, and S were found in most regular and premium gasoline. Environmental implications of trace constituents in gasoline are discussed. PMID:1157783

  4. Evaluation of the use of UCG gas to produce 4000 BPD and 12,000 BPD of methanol with conversion to M-gasoline

    Carlisle, Donald

    1981-01-01

    This study involves an examination of the technical and economic feasibility of using raw gas from an underground coal gasification facility as feedstock for methanol synthesis, and producing M-gasoline from the methanol. It differs from previous studies in considering facilities smaller than those previously studied. Addressed also is the economic and technical feasibility of using equipment from existing ammonia plants for the production of methanol. Ammonia and methanol plants are very similar in type of equipment used and plant layout. Consequently, it is possible to convert an existing ammonia plant into a methanol facility. Existing ammonia and methanol plants which contain equipment that might be utilized with UCG all use natural gas for feedstock. The processing steps in these plants can be divided into unit operations which are described. The product price analysis shows that significant economies of scale exist for the larger of the two facility sizes considered in this study. The economies of scale are evident for both the methanol/M-gasoline and methanol-only facilities. Compared to current market prices, the calculated product prices for the 4000 BPD and 12,000 BPD methanol-only facilities are within the range of competitiveness with the prices of conventionally produced methanol. The product prices calculated for the 12,000 BPD methanol/4910 BPD M-gasoline facility are, under the most optimistic assumptions, 50% higher than the current market price for unleaded gasoline.

    The acute toxicity of gasoline; its components benzene, toluene, and xylene; and the additives ethanol, methanol, and methyl tertiary butyl ether are reviewed. All of these chemicals are only moderately to mildly toxic at acute doses. Because of their volatility, these compounds are not extensively absorbed dermally unless the exposed skin is occluded. Absorption through the lungs and the gastrointestinal tract is quite efficient. After ingestion, the principal danger for a number of these chemicals, particularly gasoline, is aspiration pneumonia, which occurs mainly in children. It is currently not clear whether aspiration pneumonia would still be a problem if gasoline were diluted with ethanol or methanol. During the normal use of gasoline or mixtures of gasoline and the other solvents as a fuel, exposures would be much lower than the doses that have resulted in poisoning. No acute toxic health effects would occur during the normal course of using automotive fuels. PMID:8020435

    Microbiological growth is found frequently in the bottom of jet fuel, distillate, heavy gasoil and crude oil tanks. Experience shows that traces of water - though theoretically enough for an outbreak of growth - rarely cause problems, because the tank is most probably drained frequently. However when a water table builds up and remains untouched for some time, the likelihood for growth, leading to later operational problems, rapidly increases. Normal paraffin hydrocarbons with c{sub 8}-c{sub 16} chain length appear to be especially vulnerable; in other words the kerosene/jet fuel boiling range is mainly at risk. Heavier hydrocarbon products (diesel, light heating oils and gasoils) however have increasingly seen problems over the last 15-20 years. Lighter products - mainly the gasoline boiling range appear to have been protected from microbial problems over many years. In a laboratory it was of course possible to degrade certain kinds of naphthas and finished gasolines, but those results did not mirror the findings in the field.

  18. Reference pricing and firms' pricing strategies.

    PubMed

    Miraldo, Marisa

    2009-01-01

    Within a horizontal differentiation model and allowing for heterogeneous qualities, we analyze the effects of reference pricing reimbursement on firms' pricing strategies. With this analysis we find inherent incentives for firms' pricing behavior, and consequently we shed some light on the time consistency of such policy. The analysis encompasses different reference price rules: (i) reference price as the minimum of the observed prices in the market, (ii) reference price as a linear combination of firms' prices. Results show that under the "minimum policy" firms are not able to coordinate on higher prices while the "linear policy", implicitly, provides a coordination device. We have also found that, relatively to the "linear policy", when the reference price is the minimum of observed prices, after policy implementation, total and private expenditures are higher and consumer surplus and firms' profits are lower. With quality differentiation both the minimum and linear policies unambiguously lead to higher prices.

  19. Reduction in local ozone levels in urban São Paulo due to a shift from ethanol to gasoline use

    2014-06-01

    Ethanol-based vehicles are thought to generate less pollution than gasoline-based vehicles, because ethanol emissions contain lower concentrations of mono-nitrogen oxides than those from gasoline emissions. However, the predicted effect of various gasoline/ethanol blends on the concentration of atmospheric pollutants such as ozone varies between model and laboratory studies, including those that seek to simulate the same environmental conditions. Here, we report the consequences of a real-world shift in fuel use in the subtropical megacity of São Paulo, Brazil, brought on by large-scale fluctuations in the price of ethanol relative to gasoline between 2009 and 2011. We use highly spatially and temporally resolved observations of road traffic levels, meteorology and pollutant concentrations, together with a consumer demand model, to show that ambient ozone concentrations fell by about 20% as the share of bi-fuel vehicles burning gasoline rose from 14 to 76%. In contrast, nitric oxide and carbon monoxide concentrations increased. We caution that although gasoline use seems to lower ozone levels in the São Paulo metropolitan area relative to ethanol use, strategies to reduce ozone pollution require knowledge of the local chemistry and consideration of other pollutants, particularly fine particles.

  20. Studies on price indexes and innovation

    NASA Astrophysics Data System (ADS)

    Carreon-Rodriguez, Victor G.

    This thesis develops two studies on price indexes and innovation. The first one analyzes the problems on the computation of price indexes when there are improvements in the goods' quality. These problems arise because we use price indexes that measure the prices of the goods that consumers buy rather than the prices of the services that consumers enjoy. In order to see this, I compute a true price for gasoline that is based on the services that it provides. We ask for the cost of moving one ton at a speed of 40 mph for a distance of 100 miles. This true price is compared with the official price for gasoline. The average annual bias (the rise in the official price relative to the true price) is 3.2% per year. We also compute the hours of work required to cover that cost. We find that in 1925 there were needed almost 1.5 hours of work, while by 1992 there were just needed about 8 minutes to move one ton as specified above. The second one develops a model of Cournot competition in innovation. This model introduces two new features. First, firm's investment in research and development is divided into two pieces, expenditures in human capital and expenditures in all other inputs (called R&D for simplicity). Second, the government also allocates resources to research and development, which affect the stock of knowledge available to the firms. Some interesting results arise from this model. First, investments in human capital and in R&D are increasing in the past government's investment. Second, investments per firm are decreasing in the number of firms in the industry, but the totals are larger if some conditions on the elasticities are satisfied. Third, the welfare analysis tells us that if there are entry barriers, each firm is overinvesting in both inputs. On the other hand, if there is free entry, there are too many firms engaged in the innovative race. Finally, we perform an empirical analysis and we find that there are lagged effects of the government's investment

    One pore volume of unactivated sodium persulfate was delivered into an emplaced gasoline residual source zone at CFB Borden. Concentrations of inorganic species (S2O8(2-), SO4(2-), Na(+), dissolved inorganic carbon (DIC)) and selected gasoline compounds (benzene, toluene, ethylbenzene, xylenes, trimethylbenzenes and naphthalene) were monitored across a transect equipped with 90 multilevel sampling points for >10months post-injection. Mass loading (M˙) of compounds constructed from the transect data was used for assessment purposes. Breakthrough of inorganic species was observed when the injection slug crossed the monitoring transect. An increase in [Formula: see text] indicated persulfate consumption during oxidation of gasoline compounds or degradation due to the interaction with aquifer materials. M˙DIC increased by >100% suggesting some mineralization of gasoline compounds during treatment. Mass loading for all the monitored gasoline compounds reduced by 46 to 86% as the inorganic slug crossed the monitoring transect. The cumulative mass discharge across the monitoring transect was 19 to 58% lower than that expected without persulfate injection. After the inorganic injection slug was flushed from the source zone a partial rebound (40 to 80% of baseline levels) of mass discharge of the monitored gasoline compounds was observed. The ensemble of data collected provides insight into the fate and transport of the injected persulfate solution, and the accompanying treatment of a gasoline the source zone.

    Weekly aggregate vehicle purchase and retail gasoline price data, over the time span of 2001.01 to 2005.52, were used to determine in the Phoenix, Arizona metropolitan area if the price of gasoline helped to predict vehicle purchases. This time period and data set included the effects of rapidly changing technology and rapidly increasing retail gasoline prices. This time series econometric analysis took advantage of the Phillips-Perron and Augmented Dickey Fuller tests for stationarity, as well as the concept of Granger causality to answer this question. Short-run relationships were present and were not contingent on the gender of the purchaser. The long-run results were affirmative for female purchasers and there was not enough evidence to conclude the same for male purchasers.

    A gasoline and diesel fuel additive is composed of a mixture of alcohol, toluene, and hydrogen peroxide. The preferred ratio of these substances is 16/8/1. Also for the purpose of quality control, when the additive is to be used with diesel fuel, a few drops of diesel fuel and several drops of glycerin are added to the additive mixture to determine if the proper mixture and blending has been achieved. The process of making this additive includes vigorous agitation of the substances as they are blended together in the order of a predetermined amount of toluene being added to a predetermined quantity of alcohol, and then a chosen amount of hydrogen peroxide being added thereafter. Followed by the vigorous blending of these substances, and then immediate putting of the mixture into suitable containers, and tightly sealing the containers to prevent deterioration of the additive mixture.

  5. Essays on pricing dynamics, price dispersion, and nested logit modelling

    NASA Astrophysics Data System (ADS)

    Verlinda, Jeremy Alan

    The body of this dissertation comprises three standalone essays, presented in three respective chapters. Chapter One explores the possibility that local market power contributes to the asymmetric relationship observed between wholesale costs and retail prices in gasoline markets. I exploit an original data set of weekly gas station prices in Southern California from September 2002 to May 2003, and take advantage of highly detailed station and local market-level characteristics to determine the extent to which spatial differentiation influences price-response asymmetry. I find that brand identity, proximity to rival stations, bundling and advertising, operation type, and local market features and demographics each influence a station's predicted asymmetric relationship between prices and wholesale costs. Chapter Two extends the existing literature on the effect of market structure on price dispersion in airline fares by modeling the effect at the disaggregate ticket level. Whereas past studies rely on aggregate measures of price dispersion such as the Gini coefficient or the standard deviation of fares, this paper estimates the entire empirical distribution of airline fares and documents how the shape of the distribution is determined by market structure. Specifically, I find that monopoly markets favor a wider distribution of fares with more mass in the tails while duopoly and competitive markets exhibit a tighter fare distribution. These findings indicate that the dispersion of airline fares may result from the efforts of airlines to practice second-degree price discrimination. Chapter Three adopts a Bayesian approach to the problem of tree structure specification in nested logit modelling, which requires a heavy computational burden in calculating marginal likelihoods. I compare two different techniques for estimating marginal likelihoods: (1) the Laplace approximation, and (2) reversible jump MCMC. I apply the techniques to both a simulated and a travel mode

    This review examines the animal, human, and mechanistic studies that precede the new studies reported in this volume. Wholly vaporized unleaded gasoline was found to produce a dose-dependent increase in renal carcinoma in male rats and an excess above background incidence of hepatocellular tumors in female mice in the high-dose group. Mechanistic studies suggest that gasoline is not mutagenic and that the probable mechanism for the male rat renal tumors involves a rat-specific protein, alpha 2u-globulin, whose binding with highly branched aliphatic compounds results in renal tubule cell death and, in turn, a proliferative sequence that increases renal tubule tumors. Human evidence generated predominantly from studies of refinery workers does not support a kidney or liver cancer risk in humans. The current epidemiologic database is inadequate to access leukemia risk from low-level benzene exposure from gasoline. Studies of gasoline-exposed workers that incorporate quantitative exposure information are needed. PMID:8020448

    The regulations for gasoline's content vary depending on the time of year and physical location within the United States while the refinery and distribution system mixes product batches; this results in variability of content. ASTM E1618 requires both the aromatic and alkane EIP patterns of gasoline to compare with references. A survey was conducted by collecting gasoline from Florida to Oregon, from 85 to 93 octane. Samples were analyzed in accordance with ASTM E1618 in various states of evaporation. The range of differences found in the 90% evaporated alkane EIPs is presented and showed a continuum of response when the n-alkane response was compared with the branched alkane response. Similarly, the ratio of the alkane EIP to the aromatic EIP also showed a continuum of response at the 90% evaporated state. Gasoline samples with unusual characteristics are also discussed. © 2014 American Academy of Forensic Sciences.

    The open trade on the world market is estimated using information of one-day exchange prices of nonferrous and precious metals, oil, reduced crude, and gasoline and the main world stock indices in the time period from January 1, 2009 to December 31, 2015. It is found that the short-term changes in the prices of nonferrous metals are determined by the prices on the metal market. The changes in the prices of energy carriers and the stock trade on the stock market weakly influence the pricing of nonferrous and precious metals. The prices of metals depend on the situation during trade on commodity exchanges, and the stock market indirectly influences the exchange prices of metals through changes in the share prices of the companies that produce copper, aluminum, and zinc.

    Dating a gasoline releases is particularly important in situations involving a contaminated gasoline service station. Often the station begins under the control of a major oil company, and as it ages and deteriorates it may be operated by a series of smaller operators. When facing a claim for contamination, often operators blame former operators. Fingerprinting is one of several successful methods used to date petroleum releases on contaminated sites. The topics covered in this article are inventory reconciliation; reverse groundwater modeling; hydrocarbon fingerprinting.

    The environmental health impacts of transportation depend in part on where and when emissions occur during fuel production and combustion. Here we describe spatially and temporally explicit life cycle inventories (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover. Previous modeling for the U.S. by Argonne National Laboratory (GREET: Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation) suggested that life cycle emissions are generally higher for ethanol from corn grain or corn stover than for gasoline. Our results show that for ethanol, emissions are concentrated in the Midwestern "Corn Belt". We find that life cycle emissions from ethanol exhibit different temporal patterns than from gasoline, reflecting seasonal aspects of farming activities. Enhanced chemical speciation beyond current GREET model capabilities is also described. Life cycle fine particulate matter emissions are higher for ethanol from corn grain than for ethanol from corn stover; for black carbon, the reverse holds. Overall, our results add to existing state-of-the-science transportation fuel LCI by providing spatial and temporal disaggregation and enhanced chemical speciation, thereby offering greater understanding of the impacts of transportation fuels on human health and opening the door to advanced air dispersion modeling of fuel life cycles.

    Attached garages are known to be associated with indoor air volatile organic compounds (VOCs). This study looked at indoor exposure to VOCs presumably from evaporative emissions of gasoline. Alaskan gasoline contains 5% benzene making benzene a marker for gasoline exposure. A survey of randomly chosen houses with attached garages was done in Anchorage Alaska to determine the exposure and assess respiratory health. Householders were asked to complete a health survey for each person and a household survey. They monitored indoor air in their primary living space for benzene, toluene, ethylbenzene and xylenes for one week using passive organic vapor monitoring badges. Benzene levels in homes ranged from undetectable to 58 parts per billion. The median benzene level in 509 homes tested was 2.96 ppb. Elevated benzene levels in the home were strongly associated with small engines and gasoline stored in the garage. High concentrations of benzene in gasoline increase indoor air levels of benzene in residences with attached garages exposing people to benzene at levels above ATSDR’s minimal risk level. Residents reported more severe symptoms of asthma in the homes with high gasoline exposure (16%) where benzene levels exceeded the 9 ppb. PMID:20948946

  5. Stabilization of methanol-containing gasolines

    1994-09-01

    In other countries, methanol is used quite extensively as a component of automotive gasolines. The possibility of using methanol-containing gasolines in this country is currently under investigation. One of the basic problems in using such gasolines is their separation into phases at low temperatures when even traces of water are present. The temperature at which layer separation occurs can be lowered by the use of stabilizers such as isopropanol, isobutanol, 2-ethylhexanol, and other lower alcohols. The considerable difference between gasoline and methanol in physicochemical properties makes it necessary to use stabilizers in large amounts, up to 50% of the methanol content. The cost of stabilizers (C{sub 3}-C{sub 8} alcohols) is more than an order of magnitude higher than the cost of gasoline, and the availability of such alcohols in this country is quite limited. Because of this situation, it is of definite interest to develop new, effective stabilizers. The curtailment of oil production in this country has created a need for alternative fuels, including automotive gasolines. One possibility is the use of stabilized hydrocarbon-methanol blends (HMBs) based on waste materials from certain large-scale petrochemical production operations.

The internal combustion engine and gasoline have co-evolved until motor vehicles now annually consume about 110 billion gallons of gasoline in the United States. Continuing air pollution problems and resulting regulatory pressures are driving the need for further automotive emissions reductions. Engine and emissions control technology provided most earlier reductions. Changing the composition of gasoline will play a major role in the next round of reductions. The engineering and regulatory definition of a reformulated gasoline is proceeding rapidly, largely as the result of an auto and oil industry cooperative data generation program. It is likely that this new, reformulated gasoline will be introduced in high-ozone regions of the United States in the mid-1990s. Alternative clean fuels, primarily methane, methanol, and liquid petroleum gas, will become more widely used during this same period, probably first in fleet operations.

  8. Chemistry Impacts in Gasoline HCCI

    2006-09-01

    The use of homogeneous charge compression ignition (HCCI) combustion in internal combustion engines is of interest because it has the potential to produce low oxides of nitrogen (NOx) and particulate matter (PM) emissions while providing diesel-like efficiency. In HCCI combustion, a premixed charge of fuel and air auto-ignites at multiple points in the cylinder near top dead center (TDC), resulting in rapid combustion with very little flame propagation. In order to prevent excessive knocking during HCCI combustion, it must take place in a dilute environment, resulting from either operating fuel lean or providing high levels of either internal or external exhaust gas recirculation (EGR). Operating the engine in a dilute environment can substantially reduce the pumping losses, thus providing the main efficiency advantage compared to spark-ignition (SI) engines. Low NOx and PM emissions have been reported by virtually all researchers for operation under HCCI conditions. The precise emissions can vary depending on how well mixed the intake charge is, the fuel used, and the phasing of the HCCI combustion event; but it is common for there to be no measurable PM emissions and NOx emissions <10 ppm. Much of the early HCCI work was done on 2-stroke engines, and in these studies the CO and hydrocarbon emissions were reported to decrease [1]. However, in modern 4-stroke engines, the CO and hydrocarbon emissions from HCCI usually represent a marked increase compared with conventional SI combustion. This literature review does not report on HCCI emissions because the trends mentioned above are well established in the literature. The main focus of this literature review is the auto-ignition performance of gasoline-type fuels. It follows that this discussion relies heavily on the extensive information available about gasoline auto-ignition from studying knock in SI engines. Section 2 discusses hydrocarbon auto-ignition, the octane number scale, the chemistry behind it, its

  9. Temperate zone fens of the glaciated Midwestern USA

    2002-01-01

    A study of more than 70 fens in the Midwestern United States and a review of the literature indicates that these temperate zone wetlands may differ from fens of the boreal zone and are not adequately differentiated from them by present classification systems. Fens of the Midwestern temperate zone 1) are wetlands with high botanical diversity, 2) are supported in part by ground water with conductivity > 100mS/ cm and circumneutral pH, 3) contain water in the root zone during most of the growing season yet are not usually inundated, and 4) accumulate organic and/or carbonate substrates. Individually, none of these descriptors is adequate to distinguish fens from other wetland communities of the Midwest such as marshes, sedge meadows, and wet prairies; yet, when they are taken together, such discrimination is possible. While fens of this zone share many species, our study does not support using indicator species because too few are both faithfully represented and geographically widespread. Midwestern temperate fens are sustained by forces of climate, landscape, and geology, which permit ground water to seep continuously into the root zone in a focused location. Since water availability in the temperate Midwest is less than in the boreal zone, continuous discharge is needed to maintain the saturation conducive to peat formation. ?? 2002, The Society of Wetland Scientists.

    The composition and sources of fine particulate matter (PM2.5) were investigated in rural and urban locations in Iowa, located in the agricultural and industrial Midwestern United States, from April 2009 to December 2012. Major chemical contributors to PM2.5 mass were sulfate, nitrate, ammonium, and organic carbon. Non-parametric statistical analyses demonstrated that the two rural sites had significantly enhanced levels of crustal materials (Si, Al) driven by agricultural activities and unpaved roads. Meanwhile, the three urban areas had enhanced levels of secondary aerosols (nitrate, sulfate, and ammonium) and combustion products (elemental carbon). The Davenport site had significantly higher levels of PM2.5 and trace metals (Fe, Pb, Zn), demonstrating the important local impact of industrial point sources on air quality. Sources of PM2.5 were evaluated by using the multi-variant positive matrix factorization (PMF) source apportionment model. For each individual site, seven to nine factors were identified: secondary sulfate (accounting for 29-30% of PM2.5), secondary nitrate (17-24%), biomass burning (9-21%), gasoline combustion (6-16%), diesel combustion (3-9%), dust (6-11%), industry (0.4-5%) and winter salt (2-6%). Source contributions demonstrated a clear urban enhancement in PM2.5 from gasoline engines (by a factor of 1.14) and diesel engines (by a factor of 2.3), which is significant due to the well-documented negative health impacts of vehicular emissions. This study presents the first source apportionment results from the state of Iowa and is broadly applicable to understanding the differences in anthropogenic and natural sources in the urban-rural continuum of particle air pollution.

    This study utilizes existing data sources and previous analyses of state-level energy prices to develop consistent state-level energy prices series by fuel type and by end-use sector. The fuels are electricity, natural gas, coal, distillate fuel oil, motor gasoline, diesel, kerosene, jet fuel, residual fuel, and liquefied petroleum gas. The end-use sectors are residential, commercial, industrial, transportation, and electric utility. Based upon an evaluation of existing data sources, recommendations were formulated on the feasible approaches for developing a consistent state energy price series. The data series were compiled based upon the approaches approved after a formal EIA review. Detailed documentation was provided, including annual updating procedures. Recommendations were formulated for future improvements in the collection of data or in data processing. Generally, the geographical coverage includes the 50 states and the District of Columbia. Information on state-level energy use was generally taken from the State Energy Data System (SEDS). Corresponding average US prices are also developed using volumes reported in SEDS. To the extent possible, the prices developed are quantity weighted average retail prices. Both a Btu price series and a physical unit price series are developed for each fuel. The period covered by the data series is 1970 through 1980 for most fuels, though prices for electricity and natural gas extend back to 1960. (PSB)

    2003-08-15

    A life cycle assessment has been done to compare the potential environmental impacts of various gasoline blends that meet octane and vapor pressure specifications. The main blending components of alkylate, cracked gasoline, and reformate have different octane and vapor pressure values as well as different potential environmental impacts. Because the octane and vapor pressure values are nonlinearly related to impacts, the results of this study show that some blends are better for the environment than others. To determine blending component compositions, simulations of a reformer were done at various operating conditions. The reformate products of these simulations had a wide range of octane values and potential environmental impacts. Results of the study indicate that for low-octane gasoline (95 Research Octane Number), lower reformer temperatures and pressures generally decrease the potential environmental impacts. However, different results are obtained for high-octane gasoline (98 RON), where increasing reformer temperatures and pressures increase the reformate octane values faster than the potential environmental impacts. The higher octane values for reformate allow blends to have less reformate, and therefore high-octane gasoline can have lower potential environmental impacts when the reformer is operated at higher temperatures and pressures. In the blends studied, reformate and cracked gasoline have the highest total impacts, of which photochemical ozone creation is the largest contributor (assuming all impact categories are equally weighted). Alkylate has a much lower total potential environmental impact but does have higher impact values for human toxicity by ingestion, aquatic toxicity, terrestrial toxicity, and acidification. Therefore, depending on environmental priorities, different gasoline blends and operating conditions should be chosen to meet octane and vapor pressure specifications.

    The Energy Policy Act requires the Secretary of Energy to determine the feasibility of producing sufficient replacement fuels to replace at least 30 percent of the projected consumption of motor fuels by light duty vehicles in the year 2010. The Act also requires the Secretary to determine the greenhouse gas implications of the use of replacement fuels. A replacement fuel is a non-petroleum portion of gasoline, including certain alcohols, ethers, and other components. The Oak Ridge National Laboratory Refinery Yield Model has been used to study the cost and refinery impacts for production of {open_quotes}low petroleum{close_quotes} gasolines, which contain replacement fuels. The analysis suggests that high oxygenation is the key to meeting the replacement fuel target, and a major contributor to cost increase is investment in processes to produce and etherify light olefins. High oxygenation can also increase the costs of control of vapor pressure, distillation properties, and pollutant emissions of gasolines. Year-round low petroleum gasoline with near-30 percent non-petroleum components might be produced with cost increases of 23 to 37 cents per gallon of gasoline, and with greenhouse gas emissions changes between a 3 percent increase and a 16 percent decrease. Crude oil reduction, with decreased dependence on foreign sources, is a major objective of the low petroleum gasoline program. For year-round gasoline with near-30 percent non-petroleum components, crude oil use is reduced by 10 to 12 percent, at a cost $48 to $89 per barrel. Depending upon resolution of uncertainties about extrapolation of the Environmental Protection Agency Complex Model for pollutant emissions, availability of raw materials and other issues, costs could be lower or higher.

    Analytical data for 905 samples of motor gasoline, were collected from service stations throughout the country and were analyzed in the laboratories of various refiners, motor manufacturers, and chemical companies. The data were submitted to the Bartlesville Energy Technology Center for study, necessary calculations, and compilation under a cooperative agreement between the Bartlesville Energy Technology Center (BETC) and the American Petroleum Institute (API). The samples represent the products of 30 companies, large and small, which manufacture and supply gasoline. These data are tabulated by groups according to brands (unlabeled) and grades for 17 marketing districts into which the country is divided. A map included in this report, shows marketing areas, districts and sampling locations. The report also includes charts indicating the trends of selected properties of motor fuels since winter 1959-1960 survey for the leaded gasolines, and since winter 1979-1980 survey for the unleaded gasolines. Sixteen octane distribution percent charts for areas 1, 2, 3, and 4 for unleaded antiknock index (R+M)/2 below 90.0, unleaded antiknock index (R+M)/2 90.0 and above, leaded antiknock index (R+M)/2 below 93.0, and leaded antiknock index (R+M)/2 93.0 and above grades of gasoline are presented in this report. The antiknock (octane) index (R+M)/2 averages of gasoline sold in this country were 87.4 for unleaded below 90.0, 91.7 for unleaded 90.0 and above, and 88.9 for leaded below 93.0.

    The problem of octane mislabeling at gasoline stations in New York City has grown - from 46 or fewer citations in 1981 to 171 citations in 1986. No single source of octane mislabeling exists but the city has found both gasoline station operators and fuel distributors to blame. The problem does not seem to be unique to any one type of gasoline station but 57 percent of the 171 citations issued involved gasoline sold under the name of a major refiner; the rest involved unbranded gasoline. Octane cheating can be lucrative in New York City. A station intentionally mislabeling its gasoline could realize amounts many times the city's maximum $500 fine for cheating.

    This paper examines the demand for gasoline and diesel in the ground transportation sectors of South Korea and Taiwan, comparing the effects of their different pricing policies and stages of economic growth. To account for substitutability between the two fuels, the model proposed here uses a system of equations estimated simultaneously with time-series data from 1973--1992. Results yield demand elasticities that confirm previous research showing that oil product demand is generally price inelastic, which income elasticities (reflecting a longer period of economic growth than previous studies in the Asian region) are lower than those previously reported. The estimated demand functions are then used to generate forecasts for both countries and, in particular, for an assumed reduction in a 180% tax on gasoline in Korea. Forecasted increases in demand by the year 2010 range from 40 to 180%, while the tax analysis suggests that Korea's pricing policy has reduced total demand and promoted the use of diesel over gasoline.

    Major adverse climatic events (MACEs) in heavily-populated areas can inflict severe damage to infrastructure, disrupting essential municipal and commercial services. Compromised health care delivery systems and limited utilities such as electricity, heating, potable water, sanitation, and housing, place populations in disaster areas at risk of toxic exposures. Hurricane Sandy made landfall on October 29, 2012 and caused severe infrastructure damage in heavily-populated areas. The prolonged electrical outage and damage to oil refineries caused a gasoline shortage and rationing unseen in the USA since the 1970s. This study explored gasoline exposures and clinical outcomes in the aftermath of Hurricane Sandy. Prospectively collected, regional poison control center (PCC) data regarding gasoline exposure cases from October 29, 2012 (hurricane landfall) through November 28, 2012 were reviewed and compared to the previous four years. The trends of gasoline exposures, exposure type, severity of clinical outcome, and hospital referral rates were assessed. Two-hundred and eighty-three gasoline exposures were identified, representing an 18 to 283-fold increase over the previous four years. The leading exposure route was siphoning (53.4%). Men comprised 83.0% of exposures; 91.9% were older than 20 years of age. Of 273 home-based calls, 88.7% were managed on site. Asymptomatic exposures occurred in 61.5% of the cases. However, minor and moderate toxic effects occurred in 12.4% and 3.5% of cases, respectively. Gastrointestinal (24.4%) and pulmonary (8.4%) symptoms predominated. No major outcomes or deaths were reported. Hurricane Sandy significantly increased gasoline exposures. While the majority of exposures were managed at home with minimum clinical toxicity, some patients experienced more severe symptoms. Disaster plans should incorporate public health messaging and regional PCCs for public health promotion and toxicological surveillance.

  14. The Impact of Carbon Control on Low-Income Household Electricity and Gasoline Expenditures

    SciTech Connect

    Eisenberg, Joel Fred

    2008-06-01

    In July of 2007 The Department of Energy's (DOE's) Energy Information Administration (EIA) released its impact analysis of 'The Climate Stewardship And Innovation Act of 2007,' known as S.280. This legislation, cosponsored by Senators Joseph Lieberman and John McCain, was designed to significantly cut U.S. greenhouse gas emissions over time through a 'cap-and-trade' system, briefly described below, that would gradually but extensively reduce such emissions over many decades. S.280 is one of several proposals that have emerged in recent years to come to grips with the nation's role in causing human-induced global climate change. EIA produced an analysis of this proposal using the National Energy Modeling System (NEMS) to generate price projections for electricity and gasoline under the proposed cap-and-trade system. Oak Ridge National Laboratory integrated those price projections into a data base derived from the EIA Residential Energy Consumption Survey (RECS) for 2001 and the EIA public use files from the National Household Transportation Survey (NHTS) for 2001 to develop a preliminary assessment of impact of these types of policies on low-income consumers. ORNL will analyze the impacts of other specific proposals as EIA makes its projections for them available. The EIA price projections for electricity and gasoline under the S.280 climate change proposal, integrated with RECS and NHTS for 2001, help identify the potential effects on household electric bills and gasoline expenditures, which represent S.280's two largest direct impacts on low-income household budgets in the proposed legislation. The analysis may prove useful in understanding the needs and remedies for the distributive impacts of such policies and how these may vary based on patterns of location, housing and vehicle stock, and energy usage.

    1993-03-31

    The North American Free Trade Agreement has become a hotly debated topic all over the world, but especially in the countries involved: Mexico, United States, and Canada. Comments made by high ranking officials imply there are differences to reconcile before the agreement is passed. Toward seeing these countries in trio, this issue compares gasoline markets and some energy perspectives. The purpose of this article is to contribute to understanding of the three countries through their petroleum industry structure. Gasoline consumption and retail delivery infrastructure are compared and contrasted to illustrate the differences among the NAFTA countries.

  18. Characterizing limit order prices

    NASA Astrophysics Data System (ADS)

    Withanawasam, R. M.; Whigham, P. A.; Crack, Timothy Falcon

    2013-11-01

    A computational model of a limit order book is used to study the effect of different limit order distribution offsets. Reference prices such as same side/contra side best market prices and last traded price are considered in combination with different price offset distributions. We show that when characterizing limit order prices, varying the offset distribution only produces different behavior when the reference price is the contra side best price. Irrespective of the underlying mechanisms used in computing the limit order prices, the shape of the price graph and the behavior of the average order book profile distribution are strikingly similar in all the considered reference prices/offset distributions. This implies that existing averaging methods can cancel variabilities in limit order book shape/attributes and may be misleading.

  3. Reformulated gasoline: Costs and refinery impacts

    SciTech Connect

    Hadder, G.R.

    1994-02-01

    Studies of reformulated gasoline (RFG) costs and refinery impacts have been performed with the Oak Ridge National Laboratory Refinery Yield Model (ORNL-RYM), a linear program which has been updated to blend gasolines to satisfy emissions constraints defined by preliminary complex emissions models. Policy makers may use the reformulation cost knee (the point at which costs start to rise sharply for incremental emissions control) to set emissions reduction targets, giving due consideration to the differences between model representations and actual refining operations. ORNL-RYM estimates that the reformulation cost knee for the US East Coast (PADD I) is about 15.2 cents per gallon with a 30 percent reduction of volatile organic compounds (VOCs). The estimated cost knee for the US Gulf Coast (PADD III) is about 5.5 cents per gallon with a VOC reduction of 35 percent. Reid vapor pressure (RVP) reduction is the dominant VOC reduction mechanism. Even with anti-dumping constraints, conventional gasoline appears to be an important sink which permits RFG to be blended with lower aromatics and sulfur contents in PADD III. In addition to the potentially large sensitivity of RFG production to different emissions models, RFG production is sensitive to the non-exhaust VOC share assumption for a particular VOC model. ORNL-RYM has also been used to estimate the sensitivity of RFG production to the cost of capital; to the RVP requirements for conventional gasoline; and to the percentage of RFG produced in a refining region.

    The injectors' flow-rate of all test vehicles that each was fixed with a three-way catalytic converter (TWC) and Electronic Fuel Injection System (EFI) was tested including before and after vehicles operated on unleaded and ethanol gasoline respectively running for a long time on real road. The three main engine-out exhaust emissions (HC, CO and NOx) from vehicles operating on different fuels were also analyzed by exhaust testing procedure for the whole light-duty vehicle. Test results showed that comparing with unleaded gasoline and ethanol gasoline has a remarkable effect on decreasing engine-out exhaust emissions of CO and HC (both at about ten percent) and the exhaust emissions of CO, HC and NOx from vehicles with TWC respectively. When burning with unleaded gasoline the three main pollutants from vehicles with TWC have already or nearly reached Europe Exhaust First Standard, after changing to ethanol gasoline CO has drastically decreased at about thirty percent, while HC and NOx decreased at about eighteen and ten percent respectively, at this time which they were all above Europe Exhaust Standard First or nearly reached Europe Exhaust Second Standard; ethanol gasoline has also other better performance such as a slight cleaning function on injectors, a slower deteriorative trend of engine-out CO and HC and a longer operating life-span of TWC.

    1994-12-01

    This report (Part II) concludes a two part study of The Energy Information Administration`s (EIA) assessment of Reformulated Gasoline (RFG). The data contained herein updates EIA`s previous findings and analyses on reformulated gasoline as it affects the petroleum industry. The major findings of Part II have not changed considerably from Part I: Supplies of RFG are adequate to meet demand, but a tight supply-demand balance exists, leaving the RFG system with little ability to absorb unexpected supply or delivery system disruption. In December 1994, the estimated demand for RFG was 2.6 million barrels per day, with the production capability just meeting this demand. The study concludes that current prices for RFG are consistent with the costs underlying the product, and the difference in RFG and conventional gasoline indicates confidence in supply. The study also follows the impact of recent events such as: postponement of the Renewable Oxygenate Standard, the decision to require importers to use the U.S. average baseline for limiting emissions, the disruption of the Colonial Pipeline in Texas, and Pennsylvania`s request to opt-out of the RFG program.

    Atmospheric particulate matter (PM) exhibits heterogeneity in composition across urban areas, leading to poor representation of outdoor air pollutants in human exposure assessments. To examine heterogeneity in PM composition and sources across an urban area, fine particulate matter samples (PM2.5) were chemically profiled in Iowa City, IA from 25 August to 10 November 2011 at two monitoring stations. The urban site is the federal reference monitoring (FRM) station in the city center and the peri-urban site is located 8.0 km to the west on the city edge. Measurements of PM2.5 carbonaceous aerosol, inorganic ions, molecular markers for primary sources, and secondary organic aerosol (SOA) tracers were used to assess statistical differences in composition and sources across the two sites. PM2.5 mass ranged from 3 to 26 μg m-3 during this period, averaging 11.2 ± 4.9 μg m-3 (n = 71). Major components of PM2.5 at the urban site included organic carbon (OC; 22%), ammonium (14%), sulfate (13%), nitrate (7%), calcium (2.9%), and elemental carbon (EC; 2.2%). Periods of elevated PM were driven by increases in ammonium, sulfate, and SOA tracers that coincided with hot and dry conditions and southerly winds. Chemical mass balance (CMB) modeling was used to apportion OC to primary sources; biomass burning, vegetative detritus, diesel engines, and gasoline engines accounted for 28% of OC at the urban site and 24% of OC at the peri-urban site. Secondary organic carbon from isoprene and monoterpene SOA accounted for an additional 13% and 6% of OC at the urban and peri-urban sites, respectively. Differences in biogenic SOA across the two sites were associated with enhanced combustion activities in the urban area and higher aerosol acidity at the urban site. Major PM constituents (e.g., OC, ammonium, sulfate) were generally well-represented by a single monitoring station, indicating a regional source influence. Meanwhile, nitrate, biomass burning, food cooking, suspended dust, and

    Research was performed to develop a biofilter for the biodegradation of gasoline vapors. The overall goal of this effort was to provide information necessary for the design, construction, and operation of a commercial gasoline vapor biofilter. Experimental results indicated that relatively high amounts of gasoline vapor adsorption occur during initial exposure of the biofilter bed medium to gasoline vapors. Biological removal occurs over a 22 to 40[degrees]C temperature range with removal being completely inhibited at 54[degrees]C. The addition of fertilizer to the relatively fresh bed medium used did not increase the rates of gasoline removal in short term experiments. Microbiological analyses indicated that high levels of gasoline degrading microbes are naturally present in the bed medium and that additional inoculation with hydrocarbon degrading cultures does not appreciably increase gasoline removal rates. At lower gasoline concentrations, the vapor removal rates were considerably lower than those at higher gasoline concentrations. This implies that system designs facilitating gasoline transport to the micro-organisms could substantially increase gasoline removal rates at lower gasoline vapor concentrations. Test results from a field scale prototype biofiltration system showed volumetric productivity (i.e., average rate of gasoline degradation per unit bed volume) values that were consistent with those obtained with laboratory column biofilters at similar inlet gasoline concentrations. In addition, total benzene, toluene, ethyl-benzene, and xylene (BTEX) removal over the operating conditions employed was 50 to 55%. Removal of benzene was approximately 10 to 15% and removal of the other members of the BTEX group was much higher, typically >80%.

    1980-01-01

    An energy economist, Dr. Merklein, and a syndicated newspaper journalist, Mr. Murchison, combine their talents in one of the most scathing indictments yet of government energy policies. It is bad enough they feel that controls on petroleum have not worked to encourage energy production; worse that they should be used to mask the government's lack of a coherent energy policy - and to persuade trusting citizens that the energy producers are the culprits in this whole affair. To blame energy producers for producing too little energy is, in itself, a curious idea, they note. An entire chapter is devoted to an explanation of the windfall profits tax legislation. The authors assert that the term windfall profits is actually the grossest misnomer. It is not profits that Congress meant to tax; it is price, which makes the levy an excise tax, like those applied to tobacco products, alcoholic beverages, gasoline, cosmetics, etc. They point out that any taxes borne by the oil companies - or any other company - are not borne by the companies, but by American consumers. Their conclusion: by vastly increasing the oil industry's tax bill, we impair the industry's ability to expand production of domestic oil and thus blunt OPEC's oil weapon. The ultimate victim of current government energy policy: American consumers.

  20. Exotic grasslands on reclaimed midwestern coal mines: An ornithological perspective

    The largest grasslands in Indiana and Illinois are on reclaimed surface coal mines, which are numerous in the Illinois Coal Basin. The reclamation goal of establishing a vegetation cover with inexpensive, hardy exotic grass species (e.g., tall fescue, smooth brome) inadvertently created persistent, large grassland bird refuges. We review research documenting the importance of these sites for native prairie birds. On mines, grassland specialist birds (restricted to grassland throughout their range) prefer sites dominated by exotic grasses to those rich in forbs, whereas nonspecialist bird species show no significant preference. Midwestern mine grasslands potentially could be converted into landscapes that include native warm-season grasses and forbs adapted to the relatively dry, poor soil conditions, in addition to the present successful exotic grass stands. A key question is whether native mixtures will resist conversion to forb-rich or woody growth over the long term, as the exotic grasses have done.

    Studies of collaborative watershed groups show that effective leadership is an important factor for success. This research uses data from in-depth interviews and meeting observation to qualitatively examine leadership in a Midwestern collaborative watershed group operating with government funding. One major finding was a lack of role definition for volunteer steering-committee members. Lack of role clarity and decision-making processes led to confusion regarding project management authority among the group, paid project staff members, and agency personnel. Given the important role of government grants for funding projects to protect water quality, this study offers insight into leadership issues that groups with Clean Water Act Section 319 (h) funds may face and suggestions on how to resolve them.

    This paper describes the results of searches of herbarium and museum collections and databases for records of vertebrate and vascular plant specimens that had been collected in 15 midwestern National Park System units. The records of these specimens were previously unknown to the National Park Service (NPS). In the course of our searches, numerous obstacles were encountered that prevented us from fully completing our task. These ranged from difficulties with the way databases are structured, to poor record-keeping, to incomplete or incorrect information on the actual location of specimens within collections. Despite these problems, we are convinced that the information to be gained from such searches in invaluable, and we believe that our experience, and the recommendations we offer, may well prove instructive to others undertaking this kind of work.

    Agricultural chemicals in surface water may constitute a human health risk or have adverse effects on aquatic life. Recent research on unregulated rivers in the midwestern USA documents that elevated concentrations of herbicides occur for 1-4 months following application in late spring and early summer. In contrast, nitrate concentrations in unregulated rivers are elevated during fall, winter, and spring months. Natural and anthropogenic variables of fiver drainage basins, such as soil permeability, amount of agricultural chemicals applied, or percentage of land planted in corn, affect agricultural chemical concentration and mass transport in rivers. Presented is an analysis of selected data on agricultural chemicals collected for three regional studies conducted by the US Geological Survey. Statistical techniques such as multiple linear and logistic regression were used to identify natural and anthropogenic variables of drainage basins that have strong relations to agricultural chemical concentrations and mass transport measured in rivers. A geographic information system (GIS) was used to manage and analyze spatial data. Statistical models were developed that estimated the concentration, annual transport, and annual mean concentration of selected agricultural chemicals in midwestern rivers. Multiple linear regression models were not very successful (R2 from 0.162 to 0.517) in explaining the variance in observed agricultural chemical concentrations during post-planting runoff. Logistic regression models were somewhat more successful, correctly matching the observed concentration category in 61-80% of observations. Linear and multiple linear regression models were moderately successful (R2 from 0.522 to 0.995) in explaining the variance in observed annual transport and annual mean concentration of agricultural chemicals. Explanatory variables that were commonly significant in the regression models include estimates of agricultural chemical use, crop acreage, soil

  5. The effects of climate change on Midwestern agriculture

    Changes in climate are likely to impact future Midwestern agriculture. This study investigates changes in Midwestern crop yield and soil carbon in the future and the sensitivity of these variables to changes in individual climate parameters. The use of a bias correction technique on regional climate model precipitation and temperature data that is used as input into both a crop model and a soil nutrient cycling model is investigated. Systematic model biases are found in climate models and removing these biases using local observations can improve results when the data is used as input into crop and soil models. A quantile mapping bias correction technique, using the University of Washington's (UW) gridded precipitation and temperature as an observation reference is applied to NARCCAP's CRCM/CGCM3 daily precipitation, maximum and minimum temperatures. Bias correction removed error in past average yearly soybean and maize yield for Ames, IA by 110% and 6%, respectively. From the past (1968-1997) to the future (2040-2069) time period, maize yield decreased by 36.5%, while soybean yield increased by 1.2%. Maize yield was particularly sensitive to days above 95F, while soybean yield was most sensitive to seasonal precipitation and growing season length of the climate parameters investigated. Projections of soil carbon, net primary productivity (NPP) and soil carbon respiration were investigated using the Daycent model. When averaged over the Midewestern domain, NPP, CO2 respiration and soil carbon all increased in the future. Removing the biases from the climate model changed the output for all three variables significantly.

    Significant efforts have been made to characterize the toxicological properties of gasoline. There have been both mandatory and voluntary toxicology testing programs to generate hazard characterization data for gasoline, the refinery process streams used to blend gasoline, and individual chemical constituents found in gasoline. The Clean Air Act (CAA) (Clean Air Act, 2012: § 7401, et seq.) is the primary tool for the U.S. Environmental Protection Agency (EPA) to regulate gasoline and this supplement presents the results of the Section 211(b) Alternative Tier 2 studies required for CAA Fuel and Fuel Additive registration. Gasoline blending streams have also been evaluated by EPA under the voluntary High Production Volume (HPV) Challenge Program through which the petroleum industry provide data on over 80 refinery streams used in gasoline. Product stewardship efforts by companies and associations such as the American Petroleum Institute (API), Conservation of Clean Air and Water Europe (CONCAWE), and the Petroleum Product Stewardship Council (PPSC) have contributed a significant amount of hazard characterization data on gasoline and related substances. The hazard of gasoline and anticipated exposure to gasoline vapor has been well characterized for risk assessment purposes.

    The use of gasoline in homogeneous charge compression ignition engines (HCCI) and in duel fuel diesel - gasoline engines, has increased the need to understand its compression ignition processes under engine-like conditions. These processes need to be studied under well-controlled conditions in order to quantify low temperature heat release and to provide fundamental validation data for chemical kinetic models. With this in mind, an experimental campaign has been undertaken in a rapid compression machine (RCM) to measure the ignition of gasoline mixtures over a wide range of compression temperatures and for different compression pressures. By measuring the pressure history during ignition, information on the first stage ignition (when observed) and second stage ignition are captured along with information on the phasing of the heat release. Heat release processes during ignition are important because gasoline is known to exhibit low temperature heat release, intermediate temperature heat release and high temperature heat release. In an HCCI engine, the occurrence of low-temperature and intermediate-temperature heat release can be exploited to obtain higher load operation and has become a topic of much interest for engine researchers. Consequently, it is important to understand these processes under well-controlled conditions. A four-component gasoline surrogate model (including n-heptane, iso-octane, toluene, and 2-pentene) has been developed to simulate real gasolines. An appropriate surrogate mixture of the four components has been developed to simulate the specific gasoline used in the RCM experiments. This chemical kinetic surrogate model was then used to simulate the RCM experimental results for real gasoline. The experimental and modeling results covered ultra-lean to stoichiometric mixtures, compressed temperatures of 640-950 K, and compression pressures of 20 and 40 bar. The agreement between the experiments and model is encouraging in terms of first

    The laws of formation of price clusters are revealed upon statistical processing of the data on changing the quotation prices of nonferrous and precious metals, oil, black oil, gasoline, and natural gas in the postcrisis period from January 1, 2009 to November 1, 2013. It is found that the metal prices entering in the price cluster of nonferrous metals most strongly affect the formation of the nonferrous metal price and that the prices of precious metals and energy carriers correct the exchange price of the metal to some extent but do not determine its formation. Equations are derived to calculate the prices. The results of calculation by these equations agree well with the real nonferrous metal prices in the near future.

    Real fuels are complex mixtures of thousands of hydrocarbon compounds including linear and branched paraffins, naphthenes, olefins and aromatics. It is generally agreed that their behavior can be effectively reproduced by simpler fuel surrogates containing a limited number of components. In this work, a recently revised version of the kinetic model by the authors is used to analyze the combustion behavior of several components relevant to gasoline surrogate formulation. Particular attention is devoted to linear and branched saturated hydrocarbons (PRF mixtures), olefins (1-hexene) and aromatics (toluene). Model predictions for pure components, binary mixtures and multi-component gasoline surrogates are compared with recent experimental information collected in rapid compression machine, shock tube and jet stirred reactors covering a wide range of conditions pertinent to internal combustion engines. Simulation results are discussed focusing attention on the mixing effects of the fuel components.

    This paper presents a theoretical study using density functional theory to calculate thermodynamics properties of major molecules compounds at gas phase of fuels like gasoline, ethanol, and gasoline-ethanol mixture in thermal equilibrium on temperature range up to 1500 K. We simulated a composition of gasoline mixture with ethanol for a thorough study of thermal energy, enthalpy, Gibbs free energy, entropy, heat capacity at constant pressure with respect to temperature in order to study the influence caused by ethanol as an additive to gasoline. We used semi-empirical computational methods as well in order to know the efficiency of other methods to simulate fuels through this methodology. In addition, the ethanol influence through the changes in percentage fractions of chemical energy released in combustion reaction and the variations on thermal properties for autoignition temperatures of fuels was analyzed. We verified how ethanol reduces the chemical energy released by gasoline combustion and how at low temperatures the gas phase fuels in thermal equilibrium have similar thermodynamic behavior. Theoretical results were compared with experimental data, when available, and showed agreement. Graphical Abstract Thermodynamic analysis of fuels in gas phase.

    Lean Gasoline Direct Injection (LGDI) combustion is a promising technical path for achieving significant improvements in fuel efficiency while meeting future emissions requirements. Though Stoichiometric Gasoline Direct Injection (SGDI) technology is commercially available in a few vehicles on the American market, LGDI vehicles are not, but can be found in Europe. Oak Ridge National Laboratory (ORNL) obtained a European BMW 1-series fitted with a 2.0l LGDI engine. The vehicle was instrumented and commissioned on a chassis dynamometer. The engine and after-treatment performance and emissions were characterized over US drive cycles (Federal Test Procedure (FTP), the Highway Fuel Economy Test (HFET), and US06 Supplemental Federal Test Procedure (US06)) and steady state mappings. The vehicle micro hybrid features (engine stop-start and intelligent alternator) were benchmarked as well during the course of that study. The data was analyzed to quantify the benefits and drawbacks of the lean gasoline direct injection and micro hybrid technologies from a fuel economy and emissions perspectives with respect to the US market. Additionally that data will be formatted to develop, substantiate, and exercise vehicle simulations with conventional and advanced powertrains.

  6. Dangerous and cancer-causing properties of products and chemicals in the oil-refining and petrochemical industry--Part XXII: Health hazards from exposure to gasoline containing methyl tertiary butyl ether: study of New Jersey residents.

    PubMed

    Mehlman, M A

    1996-01-01

    Methyl tertiary butyl ether has caused the following cancers in rats and mice: kidney, testicular, liver, lymphomas, and leukemias. Thus, in the absence of adequate data on humans, it is biologically plausible and prudent to regard methyl tertiary butyl ether-for which there is sufficient evidence of carcinogenicity in experimental animals-as a probable human carcinogen. This means that some humans are at extreme risk of contracting cancers resulting from their exposure to oxygenated gasoline containing methyl tertiary butyl ether. Immediately after the introduction of methyl tertiary butyl ether into gasoline, many consumers of this product in New Jersey, New York, Alaska, Maine, Pennsylvania, Colorado, Arizona, Montana, Massachusetts, California, and other areas, experienced a variety of neurotoxic, allergic, and respiratory illnesses. These illnesses were similar to those suffered by refinery workers from the Oil, Chemical, and Atomic Workers Union who mixed methyl tertiary butyl ether with gasoline. Additionally, these illnesses occurred following exposure to extremely low levels of methyl tertiary butyl ether in gasoline, particularly when compared to the adverse health effects that occurred only after exposure to very high levels of conventional gasoline. Thus, gasoline containing methyl tertiary butyl ether exhibited substantially more toxicity in humans than gasoline without this additive. A number of oil industry-sponsored or influenced reports alleged that these illnesses were either unrelated to exposure to reformulated gasoline or were characteristic of some yet-to-be-identified communicable disease. These studies further alleged that the widespread concern was not about illness, but was merely a reaction to the odor and the five cent increase in the price of gasoline. To clarify the significance of this issue, it is important to note that consumers have been using gasoline for many decades, with complaints only occurring following exposure to high

    1989-01-01

    Light naphtha isomerization has become extremely important in recent years in helping refiners meet their gasoline pool octane demands this is especially true for the modern UOP* Penex* and TIP* technologies because of their octane production efficiency, relatively low capital cost and overall flexibility. Today there are almost 800,000 BPSD of licensed isomerization capacity worldwide; an increase of nearly 550,000 BPSD since 1982. This surge in demand has been the result of lead phase down programs, increased sales of premium gasoline and, in some areas, proposed legislation limiting benzene content of gasoline. The addition of a light naptha isomerization unit can result in a 1.0 to 3.0 octane improvement in the total gasoline pool, depending on feedstock and process configuration. The advantages include reducing reformer severity, increasing the percentage of gasoline sold as premium, or simply meeting the requirements of unleaded gasoline. These advantages are discussed in detail by the authors.

  13. Methanol as a gasoline extender: a critique.

    PubMed

    Wigg, E E

    1974-11-29

    The tests conducted with the three vehicles at different emission control levels suggest that, in the area of fuel economy and emissions, potential benefits with methanol blends are related to carburetion and are only significant in the case of the rich-operating cars built before emission control standards were imposed. Theoretical considerations related to methanol's leaning effect on carburetion support this conclusion. Potential advantages for methanol in these areas are therefore continuously diminishing as the older cars leave the roads. At present, these older cars use only about one-fourth of the totalc motor gasoline consumed and, before methanol could be used on a large scale, this fraction would be much smaller. The use of methanol in gasoline would almost certainly create severe product quality problems. Water contamination could lead to phase separation in the distribution system and possibly in the car tank as well, and this would require additional investment in fuel handling and blending equipment. Excess fuel volatility in hot weather may also have adverse effects on car performance if the methanol blends include typical concentrations of butanes and pentanes. Removal of these light hydrocarbon components would detract from methanol's role as a gasoline extender and if current fuel volatility specifications were maintained, its use could lead to a net loss in the total available energy for use in motor fuels. Car performance problems associated with excessively lean operation would also be expected in the case of a significant proportion of late-model cars which are adjusted to operate on lean fuel-air mixtures. If methanol does become available in large quantities, these factors suggest that it would be more practical to use it for purposes other than those related to the extending of motor gasoline, such as for gas turbines used for electric power generation. In this case, the "pure" methanol would act as a cleanburning fuel, having none of the

    As fuel costs steadily rise and motor vehicle collisions continue to be a leading cause of morbidity and mortality, we examined the relationship between the price of gasoline and the rate of trauma admissions related to gasoline consumption (GRT). The National Trauma Registry of the American College of Surgeons data of a rural Level I trauma center were queried over 27 consecutive months to identify the rate of trauma admissions/month related to gas utilization compared with the number of nongasoline related trauma admissions, based on season and day of the week. The average price/gallon of regular gas in our region was obtained from the NorthCarolinaGasPrices. com database. A log linear model with a Poisson distribution was created. No significant association exists between the average price/gallon of gasoline and the GRT rate across the months, seasons, and weekday and weekend periods. As the price of gas continues to rise, the rate of rural GRT does not decrease. Over a longer period of time and with skyrocketing prices, this relationship may not hold true. These findings may also be explained by the rural area where limited alternative transportation opportunities exist and a trauma patient population participating in high risk behavior regardless of cost.

  20. Comparison of alcogas aviation fuel with export aviation gasoline

    Mixtures of gasoline and alcohol when used in internal combustion engines designed for gasoline have been found to possess the advantage of alcohol in withstanding high compression without "knock" while retaining advantages of gasoline with regard to starting characteristics. Test of such fuels for maximum power-producing ability and fuel economy at various rates of consumption are thus of practical importance, with especial reference to high-compression engine development. This report discusses the results of tests which compares the performance of alcogas with x gasoline (export grade) as a standard.

  1. Calculating proper transfer prices

    SciTech Connect

    1991-01-01

    This article deals with developing a proper transfer pricing method. Decentralization is as American as baseball. While managers laud the widespread benefits of both decentralization and baseball, they often greet the term transfer price policy with a yawn. Since transfer prices are as critical to the success of decentralized firms as good pitchers are to baseball teams, this is quite a mistake on the part of our managers. A transfer price is the price charged to one division for a product or service that another division produced or provided. In many, perhaps most, decentralized organizations, the transfer pricing policies actually used are grossly inefficient and sacrifice the potential advantages of decentralization. Experience shows that far too many companies have transfer pricing policies that cost them significantly in foregone growth and profits.

    2005-01-01

    The use of glyphosate has increased rapidly, and there is limited understanding of its environmental fate. The objective of this study was to document the occurrence of glyphosate and the transformation product aminomethylphosphonic acid (AMPA) in Midwestern streams and to compare their occurrence with that of more commonly measured herbicides such as acetochlor, atrazine, and metolachlor. Water samples were collected at sites on 51 streams in nine Midwestern states in 2002 during three runoff events: after the application of pre-emergence herbicides, after the application of post-emergence herbicides, and during harvest season. All samples were analyzed for glyphosate and 20 other herbicides using gas chromatography/mass spectrometry or high performance liquid chromatography/mass spectrometry. The frequency of glyphosate and AMPA detection, range of concentrations in runoff samples, and ratios of AMPA to glyphosate concentrations did not vary throughout the growing season as substantially as for other herbicides like atrazine, probably because of different seasonal use patterns. Glyphosate was detected at or above 0.1 μg/1 in 35 percent of pre-emergence, 40 percent of post-emergence, and 31 percent of harvest season samples, with a maximum concentration of 8.7 μg/1. AMPA was detected at or above 0.1 μg/1 in 53 percent of pre-emergence, 83 percent of post-emergence, and 73 percent of harvest season samples, with a maximum concentration of 3.6 μg/1. Glyphosate was not detected at a concentration at or above the U.S. Environmental Protection Agency's maximum contamination level (MCL) of 700 μg/1 in any sample. Atrazine was detected at or above 0.1 μg/1 in 94 percent of pre-emergence, 96 percent of post-emergence, and 57 percent of harvest season samples, with a maximum concentration of 55 μg/1. Atrazine was detected at or above its MCL (3 μg/1) in 57 percent of pre-emergence and 33 percent of post-emergence samples.

  10. Contract portfolio optimization for a gasoline supply chain

    NASA Astrophysics Data System (ADS)

    Wang, Shanshan

    Major oil companies sell gasoline through three channels of trade: branded (associated with long-term contracts), unbranded (associated with short-term contracts), and spot market. The branded channel provides them with a long-term secured and sustainable demand source, but requires an inflexible long-term commitment with demand and price risks. The unbranded channel provides a medium level of allocation flexibility. The spot market provides them with the greatest allocation flexibility to the changing market conditions, but the spot market's illiquidity mitigates this benefit. In order to sell the product in a profitable and sustainable way, they need an optimal contract portfolio. This dissertation addresses the contract portfolio optimization problem from different perspectives (retrospective view and forward-looking view) at different levels (strategic level, tactical level and operational level). The objective of the retrospective operational model is to develop a financial case to estimate the business value of having a dynamic optimization model and quantify the opportunity values missed in the past. This model proves the financial significance of the problem and provides top management valuable insights into the business. BP has applied the insights and principles gained from this work and implemented the model to the entire Midwest gasoline supply chain to retrospectively review optimization opportunities. The strategic model is the most parsimonious model that captures the essential economic tradeoffs among different contract types, to demonstrate the need for a contract portfolio and what drives the portfolio. We examine the properties of the optimal contract portfolio and provide a comparative statics analysis by changing the model parameters. As the strategic model encapsulates the business problem at the macroscopic level, the tactical model resolves lower level issues. It considers the time dynamics, the information flow and contracting flow. Using

    Gasoline contamination is often found in streams and in urban storm drainage systems. These samples are usually found as weathered' gasoline/water matrix. The identification of weathered' gasoline solely through gas chromatographic fingerprints' of hydrocarbon portion is difficult. The polar components of three different weathered' gasoline/water samples were analyzed by gas chromatography/mass spectrometry and compared to similar components of the same three gasolines by this technique. This study shows that large portions of gasoline additives are partitioned into the aqueous phase, and this information can be used as an aid in identifying a weathered' gasoline sample.

    Previous evidence has shown that Parkinson disease (PD) has a heritable component, but only a small proportion of the total genetic contribution to PD has been identified. Genetic heterogeneity complicates the verification of proposed PD genes and the identification of new PD susceptibility genes. Our approach to overcome the problem of heterogeneity is to study a population isolate, the mid-western Amish communities of Indiana and Ohio. We performed genome-wide association and linkage analyses on 798 individuals (31 with PD), who are part of a 4,998 member pedigree. Through these analyses, we identified a region on chromosome 5q31.3 that shows evidence of association (p value < 1 × 10(-4)) and linkage (multipoint HLOD = 3.77). We also found further evidence of linkage on chromosomes 6 and 10 (multipoint HLOD 4.02 and 4.35 respectively). These data suggest that locus heterogeneity, even within the Amish, may be more extensive than previously appreciated.

  14. Atrazine and total triazines: Exposure patterns in midwestern surface waters

    1996-10-01

    Distributions of atrazine and total triazine exposures for aquatic organisms in the midwestern United States and Canada were characterized using the most complete datasets available, with attention to the sampling pattern used in obtaining the data. Distributions were established form stantaneous concentrations and for 96-hour and 21-day running averages. Time weighting and annualization were important to avoid distorted estimates of exposure concentrations; failure to use appropriate procedures can lead to order-of-magnitude errors in estimates of benchmarks such as the 90th percentile concentration. Atrazine and total triazine concentrations are characterized by strong seasonality, with elevated concentrations for a period of 6 to 10 weeks following application in May or June. Concentrations decline during July, August, and September, and for the rest of the year are near detection limit. Concentrations in running water are strongly influenced by storm runoff, with much higher concentrations during run off than during low-flow periods between run off events. Thus aquatic organisms in running waters experience pulsed exposures interspersed with recovery periods. 90th percentile concentrations were calculated for a number of rivers, streams, lakes, and reservoirs for comparison with ecological effects data. Total triazine concentrations are only slightly higher than atrazine concentrations in those waters for which comparisons were possible.

    2009-01-01

    To assess snacking patterns, self-efficacy, barriers, stage of change, and awareness of healthful snacks among middle-income midwestern women. Self-administered questionnaire. An urban church. Convenience sample of 56 women, mean age 43.9 years and mean body mass index (BMI) 25.9 kg/m(2). A snack quality index (SQI) assessed healthfulness of snack choices; subscales identified self-efficacy and barriers; and a test measured knowledge of healthful snacks. SQI scores were based on energy density and frequency of consumption. Correlations identified associations between SQI scores and self-efficacy and barriers. Analysis of variance identified significant differences between subscale scores for self-efficacy and barriers. Statistical significance was P < .05. The mean SQI score was 64.9%. Participants felt least confident to choose healthful snacks when experiencing negative emotions, and the most important barrier to healthful snacking was an unfavorable taste perception. The majority of the women (86%) were in the pre-action and 14% in the action stages of change for healthful snacking. The mean score on the snack knowledge test was 84.2%. These women need information concerning snacks high in fiber and low in trans fat, and interventions for enhancing self-confidence for healthful snack selection under challenging circumstances and for overcoming barriers.

  16. Decision-Making, Science and Gasoline Additives

    NASA Astrophysics Data System (ADS)

    Weaver, J. W.; Small, M. C.

    2001-12-01

    Methyl-tert butyl ether (MTBE) has been used as a gasoline additive to serve two major purposes. The first use was as an octane-enhancer to replace organic lead, beginning in 1979. The second use, which began about 1992, was as a oxygenated additive to meet requirements of the Clean Air Act Amendments (CAAA) of 1990. Generally, the amount of MTBE used for octane enhancement was lower than that required to meet CAAA requirements. An unintended consequence of MTBE use has been widespread groundwater contamination. The decision to use certain amounts of MTBE or other chemcials as gasoline additives is the outcome of economic, regulatory, policy, political, and scientific considerations. Decision makers ask questions such as "How do ground water impacts change with changing MTBE content? How many wells would be impacted? and What are the associated costs?" These are best answered through scientific inquiry, but many different approaches could be developed. Decision criteria include time, money, comprehensiveness, and complexity of the approach. Because results must be communicated to a non-technical audience, there is a trade off between the complexity of the approach and the ability to convince economists, lawyers and policy makers that results make sense. The question on MTBE content posed above was investigated using transport models, a release scenario and gasoline composition. Because of the inability of transport models to predict future concentrations, an approach was chosen to base comparative assessment on a calibrated model. By taking this approach, "generic" modeling with arbitrarily selected parameters was avoided and the validity of the simulation results rests upon relatively small extrapolations from the original calibrated models. A set of simulations was performed that assumed 3% (octane enhancement) and 11% (CAAA) MTBE in gasoline. The results were that ground water concentrations would be reduced in proportion to the reduction of MTBE in the fuel

    This paper summarizes the currently available information on gasoline exposure to the general population. In general, the largest contribution to the time weighted exposures results from exposures while indoors, which are influenced by the outside air, indoor sources, and attached garages. Personal activities, including refueling and commuting, contribute significantly higher exposures but last for only a small portion of the 24-hr time weighted average. The highest exposed group includes those individuals living near large service stations and those with contaminated water supplies. PMID:8020446

    The performance and driveability of today's smaller engines, particularly those with port fuel injectors, often are adversely affected by deposits at various places throughout the fuel induction system. These deposits can, however, be controlled by the use of optimal detergent additives, which are surface-active agents containing polar heads and hydrocarbon tails. For convenience in discussion, the gasoline detergents may be divided into two groups: low and high molecular weight. Low molecular weight detergents typically are more effective in forming protective films on metal surfaces, and high molecular weight detergents are more effective in dispersing deposit precursors.

This fixed period was to be followed with annual adjustments thereafter, NASA is establishing a new price for 1986 and beyond. In order to recover costs, that price must be higher than the initial fixed price through FY 1985. NASA intends to remain competitive. Competitive posture includes not only price, but other factors such as assured launch, reliability, and unique services. NASA's pricing policy considers all these factors.

    The aim of this study was to made assessment of health effects in 37 workers exposed to gasoline, and its constituents at gasoline stations between 1985 and 1996. Thirty-seven persons who had been exposed to gasoline for more than five years were examined. The evaluation included a medical / occupational history, haematological and biochemical examination, a physical exam, standardized psychological tests, and ultrasound examination of kidneys and liver. The groups were identical in other common parameters including age, gender (all men), and level of education (P<0. 05). The data were compared to two control groups: 61 healthy non-exposed controls and 25 workers at gasoline stations exposed to organic lead for only nine months. Peripheral smear revealed basophilic stippling and reticulocytosis. We found in chronic exposed gasoline workers haematological disorders: mild leukocytosis (7 of 37), lymphocytosis (20 of 37), mild lymhocytopenia (3 of 37), and decrease of red blood cells count (11 of 37). Results indicated that they have suffered from liver disorders: lipoid degeneration of liver (14 of 37), chronic functional damages of liver (3 of 37), cirrhosis (1 of 37). Ultrasound examination indicated chronic kidney damages (8 of 37). These results significantly differed from those of controls (P< 0.05). In 13 out of 37 workers at gasoline stations exposed to gasoline for more than 5 years the symptom of depression and decreased reaction time and motor abilities were identified. The summary of diseases of workers exposed to organic lead and gasoline are discussed.

However, volatility has generally been lower over the two most recent decades than previously. Variability over the most recent period has been high but, with the important exception of rice, not out of line with historical experience. There is weak evidence that grains price volatility more generally may be increasing but it is too early to say. PMID:20713400

    DuPont Pharmaceuticals and Glaxo Wellcome began marketing two new drugs, and the pricing of the drugs started a controversy. DuPont's efavirenz (Sustiva) was priced 60 percent higher than any other nonnucleoside reverse transcriptase inhibitor (NNRTI), with an annual retail price close to $5,000. In response, an ad hoc coalition called the Fair Price Working Group circulated a consensus statement demanding that the drug be priced like other drugs in that category. DuPont refused to reconsider, citing potency, once-daily dosing, and development costs. Several of the largest AIDS Drug Assistance Programs (ADAPs) also refused to add efavirenz to their formularies even though Dupont offered ADAPs a 5 percent rebate on the drug. Glaxo Wellcome learned from this dispute and priced its nucleoside analog abacavir at a level that ADAPs could afford, even though it is at the high end for its class of drugs. The coalition commended Glaxo for fairness in its pricing decision. Agouron and Bristol-Myers Squibb have also been criticized for repeatedly raising prices on their drugs. A continuing dialog, prior to price setting, will lead to greater understanding of a company's costs and may improve a company's reputation.

    The methods in the Gasoline2 smoothed particle hydrodynamics (SPH) code are described and tested. Gasoline2 is the most recent version of the Gasoline code for parallel hydrodynamics and gravity with identical hydrodynamics to the Changa code. As with other Modern SPH codes, we prevent sharp jumps in time-steps, use upgraded kernels and larger neighbour numbers and employ local viscosity limiters. Unique features in Gasoline2 include its Geometric Density Average Force expression, explicit Turbulent Diffusion terms and Gradient-Based shock detection to limit artificial viscosity. This last feature allows Gasoline2 to completely avoid artificial viscosity in non-shocking compressive flows. We present a suite of tests demonstrating the value of these features with the same code configuration and parameter choices used for production simulations.

    Lean NOx Trap (LNT) catalysts can effectively reduce NOx from lean engine exhaust. Significant research for LNTs in diesel engine applications has been performed and has led to commercialization of the technology. For lean gasoline engine applications, advanced direct injection engines have led to a renewed interest in the potential for lean gasoline vehicles and, thereby, a renewed demand for lean NOx control. To understand the gasoline-based reductant chemistry during regeneration, a BMW lean gasoline vehicle has been studied on a chassis dynamometer. Exhaust samples were collected and analyzed for key reductant species such as H2, CO, NH3, and hydrocarbons during transient drive cycles. The relation of the reductant species to LNT performance will be discussed. Furthermore, the challenges of NOx storage in the lean gasoline application are reviewed.

    In order to assess potential health effects resulting from exposure to ethanol-gasoline blend vapors, we previously conducted neurophysiological assessment of sensory function following gestational exposure to 100% ethanol vapor (Herr et al., Toxicologist, 2012). For comparison purposes, the current study investigated the same measures after gestational exposure to 100% gasoline evaporative condensates (GVC). Pregnant Long-Evans rats were exposed to 0, 3K, 6K, or 9K ppm GVC vapors for 6.5 h/day over GD9 – GD20. Sensory evaluations of male offspring began around PND106. Peripheral nerve function (compound action potentials, NCV), somatosensory (cortical and cerebellar evoked potentials), auditory (brainstem auditory evoked responses), and visual evoked responses were assessed. Visual function assessment included pattern elicited visual evoked potentials (VEP), VEP contrast sensitivity, and electroretinograms (ERG) recorded from dark-adapted (scotopic) and light-adapted (photopic) flashes, and UV and green flicker. Although some minor statistical differences were indicated for auditory and somatosensory responses, these changes were not consistently dose- or stimulus intensity-related. Scotopic ERGs had a statistically significant dose-related decrease in the b-wave implicit time. All other parameters of ERGs and VEPs were unaffected by treatment. All physiological responses showed changes related to stimulus intensity, and provided an estimate of detectable le

    Based on the emission test cycle of China National Regulation Stage III, the aldehyde and alkone emissions and VOCs emissions of three typical gasoline cars were studied with HPLC and TD-GC/MS and the exhausted particulates number and mass concentration were researched using ELPI. The results indicate that the unregulated emissions of different cars is diverse changed, the brake specific emission of the carbonyls in three cars are 36.44, 16.71 and 10.43 mg/km respectively and TVOC are 155.39, 103.75 and 42.29 mg/km respectively. Formaldehyde, acetaldehyde, acrolein, acetone and cyclohexanone are the main compounds in gasoline cars exhaust, which accounted for 77.9%-89.7% of total carbonyl compounds. Aromatic hydrocarbons and alkane are the main part of VOCs, the detected number of which is occupied 31.6%-39.2% and 23.1%-27.9% of VOCs. Toluene, xylene and benzene have high concentration, which are occupied 16.68%, 16.87% and 5.23% of TVOC in average. Ultra-fine particles (< 100 nm) dominate the particulates emission. Exhausted particulate number of high speeds is higher than that of slow and medium speeds.

    Given that the gas being processed in the compression plants Tia Juana 2 (PCTJ-2) and Tia Juana 3 (PCTJ-3) of Lagoven, S.A., an operating affiliate of Petroleos de Venezuela, S.A. has become learner through time, current production of natural gas liquids (NGL) and plant efficiency are significantly lower, compared to design and first obtained values. In this sense and aimed at increasing propane production, an optimization study on condensate stream recirculation and absorber installation was carried out to affect the process equilibrium constants thereby obtaining deeper extraction. Recirculation streams options were recirculation of natural gasoline obtained from the downstream fractionation process and recirculation of a conditioned, unfractionated, deethanized condensate stream. From the study, the natural gasoline recirculation scheme was determined to be the most efficient NGL recovery process. Accordingly, Lagoven, S.A. has undertaken a project to carry out this optimization scheme in PCTJ-2 and PCTJ-3. Construction stages are currently underway with completion scheduled at the end of 1997.

    The ability of a biofilm to switch between the mixtures of mostly aromatic and aliphatic hydrocarbons was investigated to assess biofiltration efficiency and potential substrate interactions. A switch from gasoline, which consisted of both aliphatic and aromatic hydrocarbons, to a mixture of volatile diesel n-alkanes resulted in a significant increase in biofiltration efficiency, despite the lack of readily biodegradable aromatic hydrocarbons in the diesel mixture. This improved biofilter performance was shown to be the result of the presence of larger size (C₉-C(12)) linear alkanes in diesel, which turned out to be more degradable than their shorter-chain (C₆-C₈) homologues in gasoline. The evidence obtained from both biofiltration-based and independent microbiological tests indicated that the rate was limited by biochemical reactions, with the inhibition of shorter chain alkane biodegradation by their larger size homologues as corroborated by a significant substrate specialization along the biofilter bed. These observations were explained by the lack of specific enzymes designed for the oxidation of short-chain alkanes as opposed to their longer carbon chain homologues.

    In response to the restrictions of polybrominated diphenyl ether (PBDE) flame retardants in various consumer products, alternative halogenated flame retardants have been subjected to increased use. Compared to aquatic ecosystems, relatively little information is available on the contamination of alternative flame retardants in terrestrial ecosystems, especially with regards to mammalian wildlife. In this study we used a top terrestrial carnivore, the bobcat (Lynx rufus), as a unique biomonitoring species for assessing flame retardant contamination in the Midwestern United States (U.S.) terrestrial ecosystems. Concentrations of ∑PBDEs (including all detectable PBDE congeners) ranged from 8.3 to 1920 ng/g lipid weight (median: 50.3 ng/g lw) in livers from 44 bobcats collected during 2013-2014 in Illinois. Among a variety of alternative flame retardants screened, Dechloranes (including anti- and syn-Dechlorane Plus and Dechlorane-602, 603, and 604), tetrabromo-o-chlorotoluene (TBCT), and hexabromocyclododecane (HBCD) were also frequently detected, with median concentrations of 28.7, 5.2, and 11.8 ng/g lw, respectively. Dechlorane analogue compositions in bobcats were different from what has been reported in other studies, suggesting species- or analogue-dependent bioaccumulation, biomagnification, or metabolism of Dechlorane chemicals in different food webs. Our findings, along with previously reported food web models, suggest Dechloranes may possess substantial bioaccumulation and biomagnification potencies in terrestrial mammalian food webs. Thus, attention should be given to these highly bioavailable flame retardants in future environmental biomonitoring and risk assessments in a post-PBDE era. Copyright © 2016.

  19. Switching to switchgrass: Pathways and consequences of bioenergy switchgrass entering the Midwestern landscape

    NASA Astrophysics Data System (ADS)

    Krohn, Brian

    The US has the ambitious goal of producing 60 billion liters of cellulosic biofuel by 2022. Researchers and US Federal Agencies have identified switchgrass (Panicum virgatum L.) as a potential feedstock for next generation biofuels to help meet this goal because of its excellent agronomic and environmental characteristics. With national policy supporting the development of a switchgrass to bioenergy industry two key questions arise: 1) Under what economic and political conditions will switchgrass enter the landscape? 2) Where on the landscape will switchgrass be cultivated given varying economic and political conditions? The goal of this dissertation is to answer these questions by analyzing the adoption of switchgrass across the upper Midwestern US at a high spatial resolution (30m) under varying economic conditions. In the first chapter, I model switchgrass yields at a high resolution and find considerable variability in switchgrass yields across space, scale, time, and nitrogen management. Then in the second chapter, I use the spatial results from chapter one to challenge the assumption that low-input (unmanaged) switchgrass systems cannot compete economically with high-input (managed) switchgrass systems. Finally, in the third chapter, I evaluate the economic and land quality conditions required for switchgrass to be competitive with a corn/soy rotation. I find that switchgrass can displace low-yielding corn/soy on environmentally sensitive land but, to be competitive, it requires economic support through payments for ecosystem services equal to 360 ha-1. With a total expenditure of 4.3 billion annually for ecosystem services, switchgrass could displace corn/soy on 12.2 million hectares of environmentally sensitive land and increase ethanol production above that from the existing corn by 20 billion liters. Thus, ecosystem services can be an effective means of meeting both bioenergy and environmental goals. Taking the three chapters in aggregate it is apparent

    The University of Minnesota collaborated with the Paul Scherrer Institute, the University of Wisconsin (UWI) and Ricardo, Inc to physically and chemically characterize the exhaust plume from recruited gasoline spark ignition (SI) vehicles. The project objectives were: (1) Measure representative particle size distributions from a set of on-road SI vehicles and compare these data to similar data collected on a small subset of light-duty gasoline vehicles tested on a chassis dynamometer with a dilution tunnel using the Unified Drive Cycle, at both room temperature (cold start) and 0 C (cold-cold start). (2) Compare data collected from SI vehicles to similar data collected from Diesel engines during the Coordinating Research Council E-43 project. (3) Characterize on-road aerosol during mixed midweek traffic and Sunday midday periods and determine fleet-specific emission rates. (4) Characterize bulk- and size-segregated chemical composition of the particulate matter (PM) emitted in the exhaust from the gasoline vehicles. Particle number concentrations and size distributions are strongly influenced by dilution and sampling conditions. Laboratory methods were evaluated to dilute SI exhaust in a way that would produce size distributions that were similar to those measured during laboratory experiments. Size fractionated samples were collected for chemical analysis using a nano-microorifice uniform deposit impactor (nano-MOUDI). In addition, bulk samples were collected and analyzed. A mixture of low, mid and high mileage vehicles were recruited for testing during the study. Under steady highway cruise conditions a significant particle signature above background was not measured, but during hard accelerations number size distributions for the test fleet were similar to modern heavy-duty Diesel vehicles. Number emissions were much higher at high speed and during cold-cold starts. Fuel specific number emissions range from 1012 to 3 x 1016 particles/kg fuel. A simple

    Gasoline compression ignition (GCI) is a low temperature combustion (LTC) concept that has been gaining increasing interest over the recent years owing to its potential to achieve diesel-like thermal efficiencies with significantly reduced engine-out nitrogen oxides (NOx) and soot emissions compared to diesel engines. In this work, closed-cycle computational fluid dynamics (CFD) simulations are performed of this combustion mode using a sector mesh in an effort to understand effects of model settings on simulation results. One goal of this work is to provide recommendations for grid resolution, combustion model, chemical kinetic mechanism, and turbulence model to accurately capture experimental combustion characteristics. Grid resolutions ranging from 0.7 mm to 0.1 mm minimum cell sizes were evaluated in conjunction with both Reynolds averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES) based turbulence models. Solution of chemical kinetics using the multi-zone approach is evaluated against the detailed approach of solving chemistry in every cell. The relatively small primary reference fuel (PRF) mechanism (48 species) used in this study is also evaluated against a larger 312-species gasoline mechanism. Based on these studies the following model settings are chosen keeping in mind both accuracy and computation costs – 0.175 mm minimum cell size grid, RANS turbulence model, 48-species PRF mechanism, and multi-zone chemistry solution with bin limits of 5 K in temperature and 0.05 in equivalence ratio. With these settings, the performance of the CFD model is evaluated against experimental results corresponding to a low load start of injection (SOI) timing sweep. The model is then exercised to investigate the effect of SOI on combustion phasing with constant intake valve closing (IVC) conditions and fueling over a range of SOI timings to isolate the impact of SOI on charge preparation and ignition. Simulation results indicate that there is an optimum SOI

  15. Hige Compression Ratio Turbo Gasoline Engine Operation Using Alcohol Enhancement

    SciTech Connect

    Heywood, John; Jo, Young Suk; Lewis, Raymond; Bromberg, Leslie; Heywood, John

    2016-01-29

    The overall objective of this project was to quantify the potential for improving the performance and efficiency of gasoline engine technology by use of alcohols to suppress knock. Knock-free operation is obtained by direct injection of a second “anti-knock” fuel such as ethanol, which suppresses knock when, with gasoline fuel, knock would occur. Suppressing knock enables increased turbocharging, engine downsizing, and use of higher compression ratios throughout the engine’s operating map. This project combined engine testing and simulation to define knock onset conditions, with different mixtures of gasoline and alcohol, and with this information quantify the potential for improving the efficiency of turbocharged gasoline spark-ignition engines, and the on-vehicle fuel consumption reductions that could then be realized. The more focused objectives of this project were therefore to: Determine engine efficiency with aggressive turbocharging and downsizing and high compression ratio (up to a compression ratio of 13.5:1) over the engine’s operating range; Determine the knock limits of a turbocharged and downsized engine as a function of engine speed and load; Determine the amount of the knock-suppressing alcohol fuel consumed, through the use of various alcohol-gasoline and alcohol-water gasoline blends, for different driving cycles, relative to the gasoline consumed; Determine implications of using alcohol-boosted engines, with their higher efficiency operation, in both light-duty and medium-duty vehicle sectors.

  16. Improving storage stability of gasoline using elevated antioxidant concentrations

    SciTech Connect

    Sommer, S.; Luria, D.; Lavie, I.; Sufrin, J.; Weiss, A.; Shuftan, M.

    1995-04-01

    The purpose of this study was to examine the feasibility of increasing storage-stability of gasoline by blending it with elevated concentrations of standard antioxidants, normally added at low concentrations to gasolines. It was thought that, by raising the concentration of these additives in the gasoline from 25 ppm to 100 ppm, the storage stability of the fuel can be improved. In this study, two types of antioxidants (an aromatic diamine type and an alkylphenol type), and a mixture of the two, were added at different concentrations to two different gasoline blends. The various blends were stored in drums, simulating tank storage conditions, for a period of 25 months. Samples were drawn at varying intervals over the test duration and tested for Existent Gum, Potential Gum, Induction Period and other properties (according to standard ASTM test procedures). It was found that raising the concentrations of the aromatic amine antioxidant adversely effected the storage stability of the gasoline blends, whereas elevated concentrations of the alkylphenol antioxidant indeed improved the gasoline`s stability.

  17. Diesel vs. gasoline emissions: Does PM from diesel or gasoline vehicles dominate in the US?

    NASA Astrophysics Data System (ADS)

    Gertler, Alan W.

    In the US, the majority of the on-road fleet and vehicle miles travelled are attributed to light-duty vehicles, which are fuelled almost entirely by gasoline. However, due to their significantly higher PM emission rates, emissions inventories have tended to attribute the majority of the mobile source PM to contributions from heavy-duty diesel vehicles and strategies to reduce mobile source PM have focused on the contribution from this source. A limited number of source attribution studies have implied that PM emission inventories over-estimate the diesel contribution and emissions from gasoline vehicles may be greater than previously believed. Other receptor-modelling studies have found diesel vehicles to be the dominant source of motor vehicle PM. The former conclusion is supported by recent on-road PM emission rate results obtained in a highway tunnel and a series of crossroad experiments. This paper describes the often-conflicting results obtained from receptor modelling studies and emission inventories and uses on-road emission factor results to estimate the relative contributions from the diesel and gasoline sectors of the fleet.

  18. The lean hunting phenomenon in gasoline engines

    SciTech Connect

    Tanaka, M.; Mochizuki, S.; Nishiwaki, N.; Miyake, M.

    1987-01-01

    A quite interesting self-excited oscillation phenomenon in engine speed, which may not be explained with the classical theory of mechanical hunting, is studied experimentally. The effects of the various engine operating variables on the phenomenon are examined using a four cycle single cylinder gasoline engine with an inertia governor. It was found that the phenomenon occurs when engines are operated at a lean air fuel ratio under light load conditions, and that the hunting phenomenon is ascribable to the temporary shift in air fuel ratio from the steady state value. This shift in air fuel ratio occurs due to the fuel flow delay into the cylinder caused by the fact that the fuel flow into the cylinder cannot follow the movement of the throttle valve.

    Strontium isotope values (87Sr/86Sr) in bone and tooth enamel have been used increasingly to identify non-local individuals within prehistoric human populations worldwide. Archaeological research in the Midwestern United States has increasingly highlighted the role of population movement in affecting interregional cultural change. However, the comparatively low level of geologic variation in the Midwestern United States might suggest a corresponding low level of strontium variation, and calls into question the sensitivity of strontium isotopes to identify non-local individuals in this region. Using strontium isotopes of archaeological fauna, we explore the degree of variability in strontium ratios across this region. Our results demonstrate measurable variation in strontium ratios and indicate the potential of strontium analysis for addressing questions of origin and population movement in the Midwestern United States.

  12. Impacts of the Midwestern Drought Forecasts of 2000.

    In March of 2000 (and again in April and May) NOAA issued long-range forecasts indicating that an existing Midwestern drought would continue and intensify through the upcoming summer. These forecasts received extensive media coverage and wide public attention. If the drought persisted and intensified during the summer of 2000, significant agricultural and water supply problems would occur. However, in late May, June, and July heavy rains fell throughout most of the Midwest, ending the drought in most areas and revealing that the forecast was incorrect for most of the Midwest. Significant media coverage was devoted to the `failed' forecast, with considerable speculation that major economic hardship had resulted from the forecast. This study assesses the effects of the failed drought forecast on agricultural and water agency actions in the Midwest. Assessment of the agricultural and water management sectors revealed notable commonalities. Most people surveyed were aware of the drought forecasts, and the information sources were diverse. One-third of those surveyed indicated they did nothing as a result of the forecasts. The decisions and actions taken by others as a result of the forecasts provided mixed impacts. The water resource actions such as conserving water, seeking new sources, and convening state drought groups resulted in little cost and were considered to be beneficial. However, in the three areas of agricultural impacts (crop production shifts, crop insurance purchases, and grain market choices), mainly negative outcomes occurred. The 13 March issuance of the forecast was too late for producers to make sizable changes in production practices or to alter insurance coverage greatly, and most forecast-based actions taken in these two areas were considered to be negative but financially minor losses. However, 48% of the 1017 producers sampled altered their normal crop marketing practices, which in 84% of the cases led to sizable losses in revenue. This loss

  13. The atmospheric aerosol-forming potential of whole gasoline vapor

    A series of sunlight-irradiated, smog-chamber experiments confirmed that the atmosphere organic aerosol formation potential of whole gasoline vapor can be accounted for solely in terms of the aromatic fraction of the fuel. The total amount of secondary organic aerosol produced from the atmospheric oxidation of whole gasoline vapor can be represented as the sum of the contributions of the individual aromatic molecular constituents of the fuel. The urban atmospheric, anthropogenic hydrocarbon profile is approximated well by evaporated whole gasoline, and thus these results suggest that it is possible to model atmospheric secondary organic aerosol formation. 23 refs., 3 figs., 2 tabs.

  14. How to implement a gasoline pool lead phase-down

    Some operational changes can be made for immediate reduction of lead concentration of gasoline that require no capital investment. For a further lead reduction, installing new refinery units and/or modifications to existing ones are required. The production of unleaded gasoline in the Riyadh refinery required improvement of the clear research octane number (RON) of light naphtha, light isomerate and reformate. However, only a once-through isomerization unit is needed if MTBE blending is planned. The paper describes how the Riyadh refinery in Saudi Arabia phased lead from their gasoline production.

  15. Pricing of new vaccines

    New vaccine pricing is a complicated process that could have substantial long-standing scientific, medical and public health ramifications. Pricing can have a considerable impact on new vaccine adoption and, thereby, either culminate or thwart years of research and development and public health efforts. Typically, pricing strategy consists of the following eleven components: (1) Conduct a target population analysis; (2) Map potential competitors and alternatives; (3) Construct a vaccine target product profile (TPP) and compare it to projected or actual TPPs of competing vaccines; (4) Quantify the incremental value of the new vaccine's characteristics; (5) Determine vaccine positioning in the marketplace; (6) Estimate the vaccine price-demand curve; (7) Calculate vaccine costs (including those of manufacturing, distribution, and research and development); (8) Account for various legal, regulatory, third party payer and competitor factors; (9) Consider the overall product portfolio; (10) Set pricing objectives; (11) Select pricing and pricing structure. While the biomedical literature contains some studies that have addressed these components, there is still considerable room for more extensive evaluation of this important area. PMID:20861678

    New vaccine pricing is a complicated process that could have substantial long-standing scientific, medical, and public health ramifications. Pricing can have a considerable impact on new vaccine adoption and, thereby, either culminate or thwart years of research and development and public health efforts. Typically, pricing strategy consists of the following ten components: 1. Conduct a target population analysis; 2. Map potential competitors and alternatives; 3. Construct a vaccine target product profile (TPP) and compare it to projected or actual TPPs of competing vaccines; 4. Quantify the incremental value of the new vaccine's characteristics; 5.

    Air pollution exposure, including passenger car emissions, may cause substantial respiratory health effects and cancer death. In western countries, the majority of passenger cars are driven by gasoline fuel. Recently, new motor technologies and ethanol fuels have been introduced to the market, but potential health effects have not been thoroughly investigated. We developed and verified a coculture model composed of bronchial epithelial cells (ECs) and natural killer cells (NKs) mimicking the human airways to compare toxic effects between pure gasoline (E0) and ethanol-gasoline-blend (E85, 85% ethanol, 15% gasoline) exhaust emitted from a flexfuel gasoline car. We drove a steady state cycle, exposed ECs for 6h and added NKs. We assessed exhaust effects in ECs alone and in cocultures by RT-PCR, flow cytometry, and oxidative stress assay. We found no toxic effects after exposure to E0 or E85 compared to air controls. Comparison between E0 and E85 exposure showed a weak association for less oxidative DNA damage after E85 exposure compared to E0. Our results indicate that short-term exposure to gasoline exhaust may have no major toxic effects in ECs and NKs and that ethanol as part of fuel for gasoline cars may be favorable.

  18. Six Sigma pricing.

    Many companies are now good at managing costs and wringing out manufacturing efficiencies. The TQM movement and the disciplines of Six Sigma have seen to that. But the discipline so often brought to the cost side of the business equation is found far less commonly on the revenue side. The authors describe how a global manufacturer of industrial equipment, which they call Acme Incorporated, recently applied Six Sigma to one major revenue related activity--the price-setting process. It seemed to Acme's executives that pricing closely resembled many manufacturing processes. So, with the help of a Six Sigma black belt from manufacturing, a manager from Acme's pricing division recruited a team to carry out the five Six Sigma steps: Define what constitutes a defect. At Acme, a defect was an item sold at an unauthorized price. Gather data and prepare it for analysis. That involved mapping out the existing pricing-agreement process. Analyze the data. The team identified the ways in which people failed to carry out or assert effective control at each stage. Recommend modifications to the existing process. The team sought to decrease the number of unapproved prices without creating an onerous approval apparatus. Create controls. This step enabled Acme to sustain and extend the improvements in its pricing procedures. As a result of the changes, Acme earned dollar 6 million in additional revenue on one product line alone in the six months following implementation--money that went straight to the bottom line. At the same time, the company removed much of the organizational friction that had long bedeviled its pricing process. Other companies can benefit from Acme's experience as they look for ways to exercise price control without alienating customers.

  19. Approximate option pricing

    As increasingly large volumes of sophisticated options (called derivative securities) are traded in world financial markets, determining a fair price for these options has become an important and difficult computational problem. Many valuation codes use the binomial pricing model, in which the stock price is driven by a random walk. In this model, the value of an n-period option on a stock is the expected time-discounted value of the future cash flow on an n-period stock price path. Path-dependent options are particularly difficult to value since the future cash flow depends on the entire stock price path rather than on just the final stock price. Currently such options are approximately priced by Monte carlo methods with error bounds that hold only with high probability and which are reduced by increasing the number of simulation runs. In this paper the authors show that pricing an arbitrary path-dependent option is {number_sign}-P hard. They show that certain types f path-dependent options can be valued exactly in polynomial time. Asian options are path-dependent options that are particularly hard to price, and for these they design deterministic polynomial-time approximate algorithms. They show that the value of a perpetual American put option (which can be computed in constant time) is in many cases a good approximation to the value of an otherwise identical n-period American put option. In contrast to Monte Carlo methods, the algorithms have guaranteed error bounds that are polynormally small (and in some cases exponentially small) in the maturity n. For the error analysis they derive large-deviation results for random walks that may be of independent interest.
