This paper explores price regulation and relative price convergence in the Canadian retail gasoline market. We use monthly data (2000–2010) on retail gasoline prices in 60 Canadian cities to investigate (i) whether the retail gasoline market in Canada has experienced a relative price convergence to the mean, which is expected, given the increased economic integration across Canadian provinces; and (ii) whether the introduction of price regulation mechanisms in New Brunswick and Nova Scotia in July 2006 had any impact on the price convergence in these provinces. We use a nonlinear panel unit root test and find solid evidence that Canadian retail gasoline markets are well integrated across locales; however, the share of converging cities reveals a significant decline since July of 2006. The impact of price regulation on price convergence is mixed; our results indicate that since the enactment of the regulation in all New Brunswick cities (9) included in the dataset, gasoline prices converge to the national mean. Volatility of price is also significantly reduced. In contrast, in the wake of price regulation in Nova Scotia, all 6 cities of the province are non-convergent to the mean with increased volatility and overall price level. - Highlights: ► The paper examines price regulation and convergence of gasoline prices in Canada. ► Overall in 2000–2010 the Canadian retail gasoline market was well integrated. ► Price convergence across cities has significantly declined since July 2006. ► The impact of price regulation at province level on a price convergence is mixed. ► The paper relies on the most advanced nonlinear panel unit root test.

Testing the Alchian-Allen Theorem: A Study of Consumer Behavior in the Gasoline Market

OpenAIRE

Robert Lawson; Lauren Raymer

2006-01-01

This paper uses a data set of daily sales at a single gasoline station over a seven year period to determine if consumers respond to relative price changes among the three grades of gasoline. Based on the reasoning of Alchian and Allen (1964) and Barzel (1976), market shares of higher quality gasoline should increase at the expense of regular grade gasoline when overall gasoline prices increase. The empirical results do not conform to this expectation. We find instead that the consumers in th...

This paper applies a Threshold Regression model to test for asymmetric pricing in the retail gasoline market in Canada, using weekly data for the period January 1990 to December 1996. We present results for 13 Canadian cities for both premium and regular gasoline. Within the context of an error correction model we test for the presence of asymmetric price behaviour using average changes in crude prices as well as various lags for the change in crude as possible thresholds. We are unable to find any evidence to support this view. 23 refs

The Spanish gasoline market: From ceiling regulation to open market pricing

Contin, I.; Correlje, A.; Huerta, E.

1999-01-01

This paper examines the evolution of the Spanish gasoline market from the abolition of the state oil monopoly (January 1993) to complete liberalization (October 1998). With the restructuring of the Spanish oil sector during the 1980s and early 1990s, a highly concentrated oligopoly emerged in the automotive fuels market. A system of price ceilings replaced the state administered prices in July 1990. Since then, new domestic and foreign operators have entered the market, particularly along the coast, near import terminals. Prices went up and then declined. These developments can be explained by an interplay of factors such as: the gradual decline in co-operation among the Spanish firms; the loss of market share of the largest of these, Repsol; the entry of independent operators and supermarkets; and the impact of the ceiling price system. By mid-1998 this system was abolished as the government considered it an impediment to further market liberalization. However, some crucial barriers to the entry of new suppliers remain

Understanding gasoline pricing in Canada

International Nuclear Information System (INIS)

2001-04-01

This brochure is designed to help consumers understand how gasoline is priced and explained why prices increase, fluctuate and vary by location, city or region. The price of a litre of gasoline reflects the costs of crude oil, refining, retailing and taxes. Taxes are usually the largest single component of gasoline prices, averaging 40 to 50 per cent of the pump price. The cost of crude oil makes up another 35 to 45 per cent of the price. Refining costs make up 10 to 15 per cent while the remaining 5 to 10 per cent represents retail costs. Gasoline retailers make a profit of about 1 cent per litre. The latest network technology allows national and regional retail chains to constantly monitor price fluctuations to change their prices at gasoline stations at a moments notice to keep up with the competition and to protect their market shares. Several government studies, plus the Conference Board of Canada, have reported that competition is working in favour of Canadian motorists. This brochure also explained the drawbacks of regulating crude and pump prices with the reminder that crude prices were regulated in the 1970s with many negative consequences. 2 tabs., 1 fig

A Dynamic Model for Road Gasoline and Diesel Consumption: An Application for Spanish Regions

Directory of Open Access Journals (Sweden)

Rosa Marina González Marrero

2012-01-01

Full Text Available This paper analyzes the factors explaining the aggregate fuel consumption for road transport in Spain in a dynamic panel data framework. Three features on this study are the use of a balanced panel using regional data, the distinction between gasoline and diesel and the specification of a dynamic panel data (DPD model and estimate it by system Generalized Methods of Moments (GMM. Our results show that most explanatory variables are significant in explaining the evolution of gasoline consumption, while diesel consumption is found to be independent of most of these factors. The differences between the markets of the gasoline (most for passenger transport use and the diesel (passenger and freight transport are important could explain the results for the diesel model. Moreover, the intensive dieselization process that has taken place in Spain over the last decade, which has resulted in diesel consumption being exposed to factors - i.e., regulatory - which are not of a strictly economic nature. This finding highlights the need to consider different explanatory variables and models for gasoline and diesel consumption, and to go further in the research. Finally, we find that traditional estimation procedures, such as fixed and random effect estimators, produce important differences with respect to system-GMM, which may even change policy recommendations.

This paper analyses retail price adjustments in the Dutch gasoline market. We estimate an asymmetric error correction model on weekly price changes for the years 1996 to 2001. We construct five datasets, one for each working day. The conclusions on asymmetric pricing are shown to differ over these datasets, suggesting that the choice of the day for which prices are observed matters more than commonly believed. In our view, the insufficient robustness of outcomes might explain the mixed conclusions found in the literature. Using two approaches, we also show that the effect of asymmetry on Dutch consumer costs is negligible

Taking the mystery out of gasoline prices

International Nuclear Information System (INIS)

Anon.

2000-01-01

Gasoline price variations in different markets of Canada are primarily driven by market forces, not necessarily by costs, according to a petroleum valuation consultant of the Newfoundland Department of Mines and Energy. Market forces include wholesale prices, the number and efficiency of stations in an area, companies' marketing strategies and customer buying preferences. Prices can be affected by any one of these forces at any time. The prediction is that wholesale prices will continue to be volatile in the next few months as the market adjusts to the changes in crude oil prices determined by OPEC as well as the summer season for gasoline. Changes in crude oil prices are usually reflected in the price of gasoline at the pump, although they do not necessarily move together. Demand which is an important factor in price, is cyclical in both the US and Canada, being lowest in the first quarter of the year, picking up during the second and third quarters with increased driving during good weather, and usually declining again in the fourth quarter with the onset of colder weather. Taxes are also a very significant component of the retail price of gasoline; in July 1998 the combined federal and provincial taxes accounted for 54 per cent of the average retail price of regular unleaded gasoline in Canada. Refining and marketing costs, the distance gasoline has to be transported to market, also influence prices at the pump

This paper re-examines the issue of asymmetries in the transmission of shocks to crude oil prices onto the retail price of gasoline. The distinguishing features are: (i) use of updated and comparable data to carry out an international comparison of gasoline markets; (ii) two-stage modeling of the transmission mechanism, in order to assess possible asymmetries at either the refinery stage, the distribution stage or both; (iii) use of asymmetric error correction models to distinguish between short-run and long-run asymmetries; (iv) explicit, possibly asymmetric, role of the exchange rate; (v) bootstrapping of F-tests of asymmetries, in order to overcome the low-power problem of conventional testing procedures. In contrast to several previous findings, the results generally point to widespread differences in both adjustment speeds and short-run responses when input prices rise or fall. (Author)

Oil industry consolidation and refined product prices. Evidence from US wholesale gasoline terminals

Kendix, Michael; Walls, W.D.

2010-01-01

Our objective in this paper is to quantify the impact of petroleum industry consolidation on refined product prices, controlling for other important factors that could also impact prices. Our empirical analysis focuses on the US petroleum refining industry using data on industry consolidation and wholesale gasoline prices collected over the interval 2000-2008. We match refinery units to wholesale city-terminal gasoline markets, and then estimate pooled cross-section time-series regressions to quantify the impact of petroleum industry consolidation on wholesale gasoline prices at city-specific terminals. The results of the empirical analysis of mergers are mixed, showing that some petroleum industry mergers resulted in statistically significant increases in refined product prices; others resulted in statistically significant declines and still others had no statistical impact at all. Our analysis of the effects of measures of market concentration - one at the level of city-specific wholesale terminals and another at the level of regional spot markets - found evidence that less concentrated markets are associated with lower price levels.

Testing optimal punishment mechanisms under price regulation : the case of the retail market for gasoline

International Nuclear Information System (INIS)

Gagne, R.; Versaevel, B.

2003-01-01

The effects of a price floor on price wars in the retail market for gasoline were analyzed. The authors selected a theoretical model which assumed a Bertrand oligopoly supergame, where firms initially collude by charging the monopolistic price. Once a deviation from this strategy is detected by the firms, a switch to a lower price is made in what can be called a punishment phase (price war), before returning to collusive prices. A natural experiment for the testing of the model was provided by the introduction of a price floor regulation in the Quebec retail market for gasoline in 1996. A Markov Switching Model with two latent states was used to simultaneously identify the periods of price-collusion/price war, and also to estimate the parameters which characterized each state. The results indicated that the intensity of price wars was reduced by the introduction of the price floor, but the expected duration of those wars was raised. 14 refs., 5 tabs., 1 fig

Competition in the retail gasoline industry

Science.gov (United States)

Brewer, Jedidiah

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

This paper explores the degree of competition in various gasoline markets and infers possible causes of price asymmetry across the globe. For this purpose we use the Dynamic Ordinary Least Square method in order to estimate price asymmetry in twelve European countries and the United States for a sample of weekly observations which spans the period from June 1996 to August 2011. The results indicate the common perception that less competitive gasoline markets exhibit price asymmetry, while highly competitive gasoline markets follow a symmetric price adjustment path. Finally, the inclusion of taxes (VAT and excise tax) into retail gasoline prices, supports the existence of price asymmetry in many European countries. - Highlights: • We examine the possible causes of gasoline price asymmetry across the globe. • We investigate the effect of taxation on the retail gasoline price adjustments. • There is a symmetric gasoline price response in the EU wholesale level. • Less competitive gasoline markets exhibit price asymmetry. • The oligopolistic structure of the gasoline markets inflates price asymmetry

The French market of leaded gasoline which decreases annually since 1993 by about 10% still amounts at present (April 1999) about 4.5 million tons/yr, i.e., 31% of the whole gasoline market. By 1. of January 2000, the stock of private and service light vehicles constrained to use leaded gasoline will be of about 1.1 million; taking into account other additional uses, by that time the essential needs of leaded gasoline are expected to amount up to 1.5 million tons/yr. By 2003 the number of these vehicles are expected to decrease down to 300,000. Thus, it appears that since January 2000 up to probably 2003 the distribution pumps have to be provided with the fuel specific to the old vehicles. To prepare the cessation of leaded gasoline, already forbidden in certain countries since many years, the petroleum industry and additive manufacturers have carried out research to develop anti-detonation additives to replace the leaded additives. Potassium-based additives appears to be efficient for health of both engines and people and as such a proposal with validity starting since 1. 2000 was issued, complying with the EN228 Standard, for which the provisions of the Standard 98/70/CE are adapted to the French regulations. Thus, to comply with the European regulations concerning unleaded fuels the refineries will manufacture the SP 95 and SP 98, the latter being better adapted to be treated with unleaded additives. The document gives details concerning the logistics, supply and characteristics of the replacement fuels. Evolution of the super-fuel selling since January 1994 to January 1999 is plotted.

Historical review of European gasoline lead content regulations and their impact on German industrial markets

Environmental protection policies in the automobile market were not implemented until the motorisation of the masses in the 1960s caused an increasing environmental burden. The rising air pollution was considered a latent danger for humans, animals and plants. In the years up to 1985 the EU passed several regulations to limit the mass pollutants CO, CxHy and NOx. Germany was the first EU-member nation to also be concerned with lead in gasoline, passing reduction regulations as early as in 1971. In 1986, several EU-member nations implemented the supply of unleaded gasoline. This decision was predominantly based on information about widespread forest damage. The reduction of lead emissions due to these regulations could be verified in different environmental systems. An example of this was the decline of atmospheric lead concentrations and human blood lead levels in Germany. The German mineral oil and automobile markets were also affected. The price trend of unleaded fuel was heavily influenced by tax incentives which benefited not only the gasoline traders but also the consumers. With regard to the distribution system, the market positions particularly of the medium-sized traders and the independent importers were weakened. In the automobile market, favourable terms of competition were experienced by producers who had already gained experience with catalyst systems in the U.S.-market. The gasoline lead content regulations had no effects on further economic indicators, except for competition. (orig.)

Preliminary findings indicate that: the fuel is not in short supply; exemption will not have an adverse impact on supply of any other petroleum product subject to the Emergency Petroleum allocation Act of 1973; competition and market force are adequate; exemption will not result in inequitable prices; and exemption will not have adverse state or regional impacts or any other adverse impacts. Chapter II provides background information on the use, production, and distribution of aviation gasoline. Chapter III analyzes the historical interaction of supply, demand, and price, and explores the market structure for aviation gasoline during 1968 to 1976, prior to and during imposition of allocation and price controls. Chapter IV examines aviation gasoline supply, demand, price, and market structure impacts of exempting aviation gasoline from controls. In Chapter V, the potential economic impacts of exemption are evaluated. Chapter VI provides a final summary of the DOE's findings and views in support of its preliminary judgment that aviation gasoline should be exempted from allocation and price regulations. (MCW)

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

Science.gov (United States)

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.

In a previous newsletter (September 1991 issue of this journal), the results of MVMA's 1990 Summer Gasoline Survey were discussed. It was noted that many gasolines containing high concentrations of olefins (over 15 percent volume) were being marketed in the northeast corridor between Washington, D.C. and Boston. Also noted was the finding that the composition of gasoline plays an important role in determining the emissions from vehicles on the road. In this newsletter, the potential effects on air quality of the more recently surveyed gasolines are discussed. Three grades of unleaded gasoline were covered in the survey (premium, intermediate, and regular). 1 tab

Figures are included in this survey for Canadian motor gasoline sales categorized by province, type of gasoline, and months of 1985 and 1986. Sales of refiners' diesel fuel oil are also categorized by province and by months of 1985 and 1986. Motor gasoline disposition for 1983-1986 is categorized into retail pump sales, road and urban transport, agriculture, public administration, and commercial and other institutional markets. Also included are figures for refiners' propane sales for 1983-1986 by province.

Consumer choice between ethanol and gasoline: Lessons from Brazil and Sweden

The introduction of flex-fuel vehicles since 2003 has made possible for Brazilian drivers to choose between high ethanol blends or gasoline depending on relative prices and fuel economies. In Sweden, flex-fuel fleets were introduced in 2005. Prices and demand data were examined for both Brazil and Sweden. Bioethanol has been generally the most cost-efficient fuel in Brazil, but not for all states. In any case, consumers in Brazil have opted for ethanol even when this was not the optimal economic choice. In Sweden, a different behavior was observed when falling gasoline prices made E85 uneconomical in late 2008. In a context of international biofuels expansion, the example of E85 in Sweden indicates that new markets could experience different consumer behavior than Brazil: demand falls rapidly with reduced price differences between ethanol and gasoline. At the same time, rising ethanol demand and lack of an international market with multiple biofuel producers could lead to higher domestic prices in Brazil. Once the limit curve is crossed, the consumer might react by shifting back to the usage of gasoline. - Research Highlights: > Brazil and Sweden both have infrastructure for high fuel ethanol blends. > Flex-fuel vehicles enable competition between ethanol and gasoline in fuel markets. > Data suggests that consumers make their fuel choice based mainly on prices. > Consumers in Sweden appear to be more price-sensitive than their Brazilian counterparts. > In the absence of international markets, high ethanol prices may drive consumers back to gasoline.

The US gasoline situation and crude oil prices

International Nuclear Information System (INIS)

Anon.

2004-01-01

Before and during the United States' summer driving season, concern over the country's gasoline supply can potentially influence the direction of the petroleum market. There are three causes of concern: a persistent lack of gasoline-producing capacity; a patchwork of as many as 18 different kinds of gasoline specifications; and the introduction of stringent new specifications for reformulated gasoline. However, gasoline stocks should be able to meet the needs of this year's driving season, at a time of ample crude oil availability, with strong imports. But, unplanned outages in the US logistics system and refining centres, or major disruptions in external gasoline supplies, could trigger price spikes that would, in turn, lead to frequently stronger crude oil prices, especially with the observed robust oil demand growth in China.

Standby Gasoline Rationing Plan. Contingency gasoline rationing regulations

Energy Technology Data Exchange (ETDEWEB)

1979-02-01

The Economic Regulatory Administration issues final rules with respect to standby gasoline rationing. The plan is designed for and would be used only in the event of a severe gasoline shortage. The plan provides that eligibility for ration allotments will be primarily on the basis of motor vehicle registrations. DOE will mail government ration checks to the parties named in a national vehicle registration file to be maintained by DOE. Ration recipients may cash these checks for ration coupons at various designated coupon issuance points. Retail outlets and other suppliers will be required to redeem the ration coupons received in exchange for gasoline sold. Supplemental gas will be given to high-priority activities. A ration banking system will be established with two separate and distinct of ration accounts: retail outlets and other suppliers will open redemption accounts for the deposit of redeemed ration rights; and individuals or firms may open ration rights accounts, which will operate in much the same manner as monetary checking accounts. A white market will be permitted for the sale of transfer of ration rights. A percentage of the total ration rights to be issued will be reserved for distribution to the states as a State Ration Reserve, to be used by the states primarily for the relief of hardship. A National Ration Reserave will also be established. All sections of the Standby Gasoline Rationing Regulations are analyzed. (MCW)

Report on the inquiry into sale price fluctuations of gasoline and diesel fuel in the regions of Abitibi-Temiscamingue, Saguenay-Lac Saint Jean and the Upper Mauricie, October 1998 to 31 December 1999

An inquiry was initiated by the President of the Quebec Energy Board (Regie de l'energie) on October 7, 1999 to review the reasons for the wide fluctuations in the retail sale prices of gasoline and diesel fuel in the regions of Abitibi-Temiscamingue, Saguenay/Lac-Saint-Jean and the Upper Mauricie, although the Board has no jurisdiction over the prices charged for petroleum products or anti-competitive practices. Consequently, the inquiry confined itself to an analysis of the information pertaining to the structure and forces driving the petroleum products market, and an examination of price mechanisms and consumer reactions in these regions. The inquiry reviewed the relevant legislation and regulation, the social, economic and energy situations in the affected regions, and the structure and functioning of the market for gasoline and diesel fuel. The inquiry came to the conclusion that the price fluctuations during the period under review reflected the wholesale prices recorded at Montreal and Quebec, which are determined by national and international market forces over which Quebec has no significant control. Furthermore, the inquiry concluded that although market forces are present and functioning in the regions, there are relatively few outlets affiliated with major oil companies, and a large number of independent retail outlets with relatively small volumes of annual sales.

Consumer choice between ethanol and gasoline: Lessons from Brazil and Sweden

International Nuclear Information System (INIS)

Pacini, Henrique; Silveira, Semida

2011-01-01

The introduction of flex-fuel vehicles since 2003 has made possible for Brazilian drivers to choose between high ethanol blends or gasoline depending on relative prices and fuel economies. In Sweden, flex-fuel fleets were introduced in 2005. Prices and demand data were examined for both Brazil and Sweden. Bioethanol has been generally the most cost-efficient fuel in Brazil, but not for all states. In any case, consumers in Brazil have opted for ethanol even when this was not the optimal economic choice. In Sweden, a different behavior was observed when falling gasoline prices made E85 uneconomical in late 2008. In a context of international biofuels expansion, the example of E85 in Sweden indicates that new markets could experience different consumer behavior than Brazil: demand falls rapidly with reduced price differences between ethanol and gasoline. At the same time, rising ethanol demand and lack of an international market with multiple biofuel producers could lead to higher domestic prices in Brazil. Once the limit curve is crossed, the consumer might react by shifting back to the usage of gasoline. - Research highlights: → Brazil and Sweden both have infrastructure for high fuel ethanol blends. → Flex-fuel vehicles enable competition between ethanol and gasoline in fuel markets. → Data suggests that consumers make their fuel choice based mainly on prices. → Consumers in Sweden appear to be more price-sensitive than their Brazilian counterparts. → In the absence of international markets, high ethanol prices may drive consumers back to gasoline.

Canadian retail petroleum markets study

A retail petroleum market study was conducted to provide a comprehensive overview of the competitiveness of the downstream petroleum industry in Canada and to set a foundation for effective policy development. The downstream petroleum industry, which includes the petroleum refining and marketing sectors, faces a poor public image, competitive pressures from U.S. and offshore refiners, and a broad range of environmental challenges. In this study, 19 markets representing a wide range of conditions were chosen for a detailed review of outlet economics. A market-by-market and regional comparisons of key competitiveness indicators was made in order to identify market and regional competitive differences as potential issues or opportunities within the industry. The study also included a pump price/margin model and provided a general overview of the retail gasoline sub-sector in terms of infrastructure. A review of prices, margins and demand patterns over the past several years was also undertaken to show the relationship between consumer demand patterns and pump price fluctuations. The study presented 22 findings which led to several conclusions and recommendations regarding the competitiveness of Canada's petroleum marketing sector. Two of the key conclusions were that taxation is a significant factor in the price of retail gasoline (about 50 per cent) and that government intervention into petroleum marketing is likely to be a poor alternative to market-based regulation. 18 tabs., 37 figs

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.

Ethanol-gasoline blended fuels have been widely applied in markets recently, as ethanol reduces life-cycle greenhouse gas emissions and improves anti-knock performance. However, its effects on particulate matter (PM) emissions from gasoline direct injection (GDI) engine still need further investigation. In this study, the effects of ethanol-gasoline blended fuels on particle size distributions, number concentrations, chemical composition and soot oxidation activity of GDI engine were investigated. It was found that ethanol-gasoline blended fuels increased the particle number concentration in low-load operating conditions. In higher load conditions, the ethanol-gasoline was effective for reducing the particle number concentration, indicating that the chemical benefits of ethanol become dominant, which could reduce soot precursors such as large n-alkanes and aromatics in gasoline. The volatile organic mass fraction in ethanol-gasoline particulates matter was higher than that in gasoline particulate matter because ethanol reduced the amount of soot precursors during combustion and thereby reduced the elemental carbon proportions in PM. Ethanol addition also increased the proportion of small particles, which confirmed the effects of ethanol on organic composition. Ethanol-gasoline reduced the concentrations of most PAH species, except those with small aromatic rings, e.g., naphthalene. Soot from ethanol-gasoline has lower activation energy of oxidation than that from gasoline. The results in this study indicate that ethanol-gasoline has positive effects on PM emissions control, as the soot oxidation activity is improved and the particle number concentrations are reduced at moderate and high engine loads. - Highlights: • Ethanol-gasoline reduces elemental carbon in PM. • Ethanol-gasoline increases volatile organic fraction in PM. • Soot generated from ethanol-gasoline has higher oxidation activity.

Product differentiation, competition and prices in the retail gasoline industry

Science.gov (United States)

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.

Tiered gasoline pricing: A personal carbon trading perspective

Li, Yao; Fan, Jin; Zhao, Dingtao; Wu, Yanrui; Li, Jun

2016-01-01

This paper proffers a tiered gasoline pricing method from a personal carbon trading perspective. An optimization model of personal carbon trading is proposed, and then, an equilibrium carbon price is derived according to the market clearing condition. Based on the derived equilibrium carbon price, this paper proposes a calculation method of tiered gasoline pricing. Then, sensitivity analyses and consumers' surplus analyses are conducted. It can be shown that a rise in gasoline price or a more generous allowance allocation would incur a decrease in the equilibrium carbon price, making the first tiered price higher, but the second tiered price lower. It is further verified that the proposed tiered pricing method is progressive because it would relieve the pressure of the low-income groups who consume less gasoline while imposing a greater burden on the high-income groups who consume more gasoline. Based on these results, implications, limitations and suggestions for future studies are provided. - Highlights: • Tiered gasoline pricing is calculated from the perspective of PCT. • Consumers would be burdened with different actual gasoline costs. • A specific example is provided to illustrate the calculation of TGP. • The tiered pricing mechanism is a progressive system.

Autoignition characteristics of oxygenated gasolines

KAUST Repository

Gasoline anti-knock quality, defined by the research and motor octane numbers (RON and MON), is important for increasing spark ignition (SI) engine efficiency. Gasoline knock resistance can be increased using a number of blending components. For over two decades, ethanol has become a popular anti-knock blending agent with gasoline fuels due to its production from bio-derived resources. This work explores the oxidation behavior of two oxygenated certification gasoline fuels and the variation of fuel reactivity with molecular composition. Ignition delay times of Haltermann (RON = 91) and Coryton (RON = 97.5) gasolines have been measured in a high-pressure shock tube and in a rapid compression machine at three pressures of 10, 20 and 40 bar, at equivalence ratios of φ = 0.45, 0.9 and 1.8, and in the temperature range of 650–1250 K. The results indicate that the effects of fuel octane number and fuel composition on ignition characteristics are strongest in the intermediate temperature (negative temperature coefficient) region. To simulate the reactivity of these gasolines, three kinds of surrogates, consisting of three, four and eight components, are proposed and compared with the gasoline ignition delay times. It is shown that more complex surrogate mixtures are needed to emulate the reactivity of gasoline with higher octane sensitivity (S = RON–MON). Detailed kinetic analyses are performed to illustrate the dependence of gasoline ignition delay times on fuel composition and, in particular, on ethanol content.

The effects of recent volatility in international petroleum markets on Canadian wholesale and retail gasoline prices : a report prepared for the Competition Bureau

International Nuclear Information System (INIS)

Roseman, F.

2005-03-01

This report addresses concern over high retail prices of gasoline and the low margins earned on gasoline sales in the Greater Toronto Area and in Ottawa, Ontario. The focus of this report was to understand reasons behind fluctuating prices, and to ascertain whether or not escalations in price were in fact anti-competitive acts that the Competition Bureau would have authority to take action over. Information requests were made by the author to all principal petroleum companies and to importers and marketers of gasoline. Detailed information on pricing was provided. Issues of supply and demand were responsible for spikes in prices. Information on petroleum refining and retailing of gasoline was reviewed, as well as information provided from dialogue and shareholder reports. Average refinery and retail margins in Ontario were discussed. It was concluded that fluctuating prices are the result of the petroleum industry's struggle to meet high demand. Any unscheduled maintenance or unanticipated increases in demand resulted in temporary shortfalls in supply, which led to higher prices. Exports were not a factor in increases in retail prices. In addition, domestic supply and the high cost of meeting environmental regulations with regard to sulphur levels in gasoline and diesel may have also played a role. It was also suggested that prices in Canada reflect overall pricing trends in the United States. tabs., figs

Evaluation of Anti-Knock Quality of Dicyclopentadiene-Gasoline Blends

2017-03-28

Increasing the anti-knock quality of gasoline fuels can enable higher efficiency in spark ignition engines. In this study, the blending anti-knock quality of dicyclopentadiene (DCPD), a by-product of ethylene production from naphtha cracking, with various gasoline fuels is explored. The blends were tested in an ignition quality tester (IQT) and a modified cooperative fuel research (CFR) engine operating under homogenous charge compression ignition (HCCI) and knock limited spark advance (KLSA) conditions. Due to current fuel regulations, ethanol is widely used as a gasoline blending component in many markets. In addition, ethanol is widely used as a fuel and literature verifying its performance. Moreover, because ethanol exhibits synergistic effects, the test results of DCPD-gasoline blends were compared to those of ethanol-gasoline blends. The experiments conducted in this work enabled the screening of DCPD auto-ignition characteristics across a range of combustion modes. The synergistic blending nature of DCPD was apparent and appeared to be greater than that of ethanol. The data presented suggests that DCPD has the potential to be a high octane blending component in gasoline; one which can substitute alkylates, isomerates, reformates, and oxygenates.

Petroleum product market outlook

International Nuclear Information System (INIS)

2005-09-01

The influence of petroleum market disturbances on price increases was discussed with particular reference to Hurricane Katrina and the loss of refinery production and damage to oil infrastructure in the United States. The supply of petroleum products in Canada will be very tight heading into the winter of 2006, despite the fact that Canadian refineries are operating at full capacity to ensure an adequate supply of gasoline and diesel fuel for consumers. In addition to refinery production, petroleum supplies are also determined by the adequacy of inventories and the efficiency of the infrastructure in place to deliver products to where they are needed. The lack of spare capacity has reduced the flexibility of the North American refining system to respond to further disruptions. Refiners were asked to provide information on 4 areas of their operations in order for Natural Resources Canada to analyze the short-term outlook for petroleum products markets. The 4 areas included refinery utilization rates and capability to increase production; any planned refinery turnaround that would affect petroleum product supplies; inventory levels compared to levels in previous years; and, any logistical problems that could affect product distribution. A graph depicting the relationship between Canadian production of gasoline and domestic sales clearly illustrated the seasonal nature of gasoline consumption and that production in Canada is much higher than consumption. Canada exports large volumes of gasoline, primarily to the United States eastern seabord from refineries in Atlantic Canada. The trend is similar for diesel fuel. Demand for both gasoline and diesel is expected to continue to grow in 2005 as high prices have had a limited impact on demand growth. In general, the Ontario/Quebec region is short of gasoline and must import gasoline during the summer months to cover the shortfall. It was noted that motorists and homeowners who heat with oil will bear the burden of higher

An up-to-date profile of the Canadian gasoline industry was presented with an effort to address some of the preoccupations of industry stakeholders and the perceptions of Canadian motorists. This study provides new insights into the workings of the industry by providing a balanced perspective on the many contentious issues that affect the industry, particularly retail pricing. The Conference Board's empirical analysis makes use of a new approach which provides a better understanding of how retail prices react to changes in wholesale prices. Competition is the reason why a retail market outcome margin exists in each city based on local conditions. This margin is the basis for price changes in that market and reflects a margin at which most competitors are able to sustain themselves. When changes occur in the wholesale price of crude, the retail price is adjusted depending on whether the actual margin in place is higher or lower than the market outcome margin. Crude oil and taxes make up about 84 per cent of the average price of a litre of regulated unleaded gasoline. The main reason for rising Canadian gasoline prices is the rapid increase in world crude oil prices. The volatility in gasoline prices is a direct result of the competitive nature of the business at the street level and the uniformity of prices reflects the rapid response of individual dealers to the actions of their competitors. Each outlet has fixed costs to cover, therefore average sales volumes per outlet have an important impact on retail margins and prices. It was also emphasized that there is no empirical proof that gasoline prices increase before long weekends, nor is there any proof of asymmetry in price adjustment in the retail market. It was noted that the price of gasoline in Canada and the United States, excluding taxes, is very similar. 15 tabs., 59 figs

Tushingham, M.

1996-01-01

A comprehensive database of the benzene and aromatics levels of gasoline produced in or imported into Canada during 1994, was presented. Environment Canada conducted a survey that requested refineries and importers to report quarterly on benzene and aromatics levels in gasoline. Benzene, which has been declared toxic by the Canadian Environmental Protection Act, is found in gasoline and is formed during the combustion of the aromatic components of gasoline. It was shown that benzene and aromatics levels differ regionally and seasonally. There are also variations in benzene levels between batches of gasoline produced at any one refinery. This report listed the responses to the benzene/aromatics survey. It also described the analytical procedures used to measure benzene and aromatics levels in gasoline, and provided guidelines for reporting gasoline benzene and total aromatics data. 7 tabs., 21 figs

The market and consumer welfare effects of mid-level ethanol blends in the US fuel market

Gallagher, Paul W.; Sleper, Daniel

2016-01-01

This study examines the prospect that a consumer-driven market could eventually replace the myriad regulations and demand quotas in the US ethanol and gasoline fuel market. Given efficient households that minimize the cost of operating automobiles, recent vehicle technology that improves blended fuel substitution, and typical market conditions of the last five years, blended fuels with 20% ethanol concentration could occupy a volume of 82.2 billion gallons in a 138.3 billion gallon gasoline market. The consumer welfare gain associated with blended fuel is $15.9 billion annually for US consumers, or about $1000 over the life of a vehicle. The ethanol demand associated with a voluntary blended fuel market is 16.4 BGY, slightly more than the conventional component of the Renewable Fuels Standard. It is time to replace the corn RFS with a free market. But an active competition policy in the fuel marketing system may also be required. Intervention for the impending Biomass Ethanol Industry, such as a subsidy or an exemption a carbon tax, may also be in order. - Highlights: • Competiveness of 20% ethanol blends replacing gasoline is examined. • Households can reduce costs by $1000 over vehicle life with ethanol blend. • Blended fuel could gain a 60% share in a voluntary US gasoline market. • US ethanol supply in a voluntary market would match current mandated output.

Direct injection compression ignition engines running on gasoline-like fuels have been considered an attractive alternative to traditional spark ignition and diesel engines. The compression and lean combustion mode eliminates throttle losses yielding higher thermodynamic efficiencies and the better mixing of fuel/air due to the longer ignition delay times of the gasoline-like fuels allows better emission performance such as nitric oxides (NOx) and particulate matter (PM). These gasoline-like fuels which usually have lower octane compared to market gasoline have been identified as a viable option for the gasoline compression ignition (GCI) engine applications due to its lower reactivity and lighter evaporation compared to diesel. The properties, specifications and sources of these GCI fuels are not fully understood yet because this technology is relatively new. In this work, a GCI fuel matrix is being developed based on the significance of certain physical and chemical properties in GCI engine operation. Those properties were chosen to be density, temperature at 90 volume % evaporation (T90) or final boiling point (FBP) and research octane number (RON) and the ranges of these properties were determined from the data reported in literature. These proposed fuels were theoretically formulated, while applying realistic constraints, using species present in real refinery streams. Finally, three-dimensional (3D) engine computational fluid dynamics (CFD) simulations were performed using the proposed GCI fuels and the similarities and differences were highlighted.

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

Science.gov (United States)

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

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.

But instead, today this region has a higher populationgrowth than the average of Baden-Württemberg and is the best economic region outside of urban centers. Scientists spoke aboutan overheated economic growth during the last years that in 2008 comes to a normal but still high level. To attract high potentialworkers and engineers to support further growth, the region has one main advantage to many other regions – its environment. In caseof “Lake of Constance” region, different marketing strategies were used. The complexity of successful marketing for a region is highand finding the right combination of marketing strategies is difficult but can positively influence the development of a region, itseconomy and tourism. At the same time, the marketing for economy and tourism positively reflects degree of popularity in the region.

The market for gasoline cars and diesel cars

In Europe the tax tariff is much lower for diesel fuel than for gasoline. This benefit is used by manufacturers to increase the price of diesel-fueled cars, which limits the possibility to control the use of diesel cars by means of a fiscal policy (tax incidence). Attention is paid to the impact of fiscal advantages for diesel cars on the purchasing behavior of the consumer and the pricing policy (price discrimination) of the car manufacturers. 1 ref

Highlights: • A process-based, well-to-wheel conceptualized life cycle assessment model is established. • The impacts of using low-octane gasoline on compression ignition engines are examined. • Life cycle energy consumption and GHG emissions reductions are 24.6% and 21.6%. • Significant technical and market barriers are still to be overcome. - Abstract: The use of low-octane gasoline on Gasoline Compression Ignition (GCI) engines is considered as a competitive alternative to the conventional vehicle propulsion technologies. In this study, a process-based, well-to-wheel conceptualized life cycle assessment model is established to estimate the life cycle energy consumption and greenhouse gas (GHG) emissions of the conventional gasoline-Spark Ignition (SI) and low-octane gasoline-GCI pathways. It is found that compared with the conventional pathway, the low-octane gasoline-GCI pathway leads to a 24.6% reduction in energy consumption and a 22.8% reduction in GHG emissions. The removal of the isomerization and catalytic reforming units in the refinery and the higher energy efficiency in the vehicle use phase are the substantial drivers behind the reductions. The results indicate that by promoting the use of low-octane gasoline coupled with the deployment of GCI vehicles, considerable reductions of energy consumption and GHG emissions in the transport sector can be achieved. However, significant technical and market barriers are still to be overcome. The inherent problems of NO_x and PM exhaust emissions associated with GCI engines need to be further addressed with advanced combustion techniques. Besides, the yield of low-octane gasoline needs to be improved through adjusting the refinery configurations.

After Mercedes-Benz launched the first lean-combustion gasoline engines with spray-guided combustion in 2006, it rolled out this technology on a broad level based on the engine model series featuring the BlueDIRECT combustion system. Although these engines raise the bar among competitors in terms of fuel consumption, they are currently available only in countries that offer sulfur-free fuel. This leads to the question of what technical measures or altered constraints would be necessary to allow this environmentally-friendly technology to enjoy more widespread use. The following paper discusses how the accessibility of the lean-combustion technology can be improved by focusing primarily on the USA and China as potential markets. Challenges are involved, of course, in particular with respect to fuel quality and emissions as well as the market-specific implications for on-board diagnostics. By working to further reduce fuel sulfur content, however, lean-combustion gasoline engines could also be offered in the aforementioned regions in the mid-term. (orig.)

Short-term inhalation toxicity of methanol, gasoline, and methanol/gasoline in the rat.

Poon, R; Chu, I; Bjarnason, S; Vincent, R; Potvin, M; Miller, R B; Valli, V E

1995-01-01

Four- to five-week-old male and female Sprague Dawley rats were exposed to vapors of methanol (2500 ppm), gasoline (3200 ppm), and methanol/gasoline (2500/3200 ppm, 570/3200 ppm) six hours per day, five days per week for four weeks. Control animals were exposed to filtered room air only. Depression in body weight gain and reduced food consumption were observed in male rats, and increased relative liver weight was detected in rats of both sexes exposed to gasoline or methanol/gasoline mixtures. Rats of both sexes exposed to methanol/gasoline mixtures had increased relative kidney weight and females exposed to gasoline and methanol/gasoline mixtures had increased kidney weight. Decreased serum glucose and cholesterol were detected in male rats exposed to gasoline and methanol/gasoline mixtures. Decreased hemoglobin was observed in females inhaling vapors of gasoline and methanol/gasoline at 570/3200 ppm. Urine from rats inhaling gasoline or methanol/gasoline mixtures had up to a fourfold increase in hippuric acid, a biomarker of exposure to the toluene constituent of gasoline, and up to a sixfold elevation in ascorbic acid, a noninvasive biomarker of hepatic response. Hepatic mixed-function oxidase (aniline hydroxylase, aminopyrine N-demethylase and ethoxyresorufin O-deethylase) activities and UDP-glucuronosyltransferase activity were elevated in rats exposed to gasoline and methanol/gasoline mixtures. Histopathological changes were confined to very mild changes in the nasal passages and in the uterus, where decreased incidence or absence of mucosal and myometrial eosinophilia was observed in females inhaling gasoline and methanol/gasoline at 570/3200 ppm. It was concluded that gasoline was largely responsible for the adverse effects, the most significant of which included depression in weight gain in the males, increased liver weight and hepatic microsomal enzyme activities in both sexes, and suppression of uterine eosinophilia.

Proposed standby gasoline rationing plan: public comments

Energy Technology Data Exchange (ETDEWEB)

1978-12-01

Under the proposed plan, DOE would allocate ration rights (rights to purchase gasoline) to owners of registered vehicles. All vehicles in a given class would receive the same entitlement. Essential services would receive supplemental allotments of ration rights as pririty firms. Once every 3 months, ration checks would be mailed out to all vehicle registrants, allotting them a certain amount of ration rights. These checks would then be cashed at Coupon Issuance Points, where the bearer would receive ration coupons to be used at gasoline stations. Large users of gasoline could deposit their allotment checks in accounts at ration banks. Coupons or checks would be freely exchangeable in a white market. A certain percentage of the gasoline supply would be set aside in reserve for use in national emergencies. When the plan was published in the Federal Register, public comments were requested. DOE also solicited comments from private citizens, public interest groups, business and industry, state and local governments. A total of 1126 responses were reveived and these are analyzed in this paper. The second part of the report describes how the comments were classified, and gives a statistical breakdown of the major responses. The last section is a discussion and analysis of theissue raised by commenting agencies, firms, associations, and individuals. (MCW)

Full Text Available This study explores the fundamental driving forces of regional equity market integration in a trading bloc. The determinant factors are categorized into market attribute, economic fundamentals and world information. Our sample consists of 26 equity markets of ive regional trading blocs, namely AFTA, CER, EFTA, EU and NAFTA over the period of January 1999 to  August  2005.  We  measure  market  integration  based  on  pricing  errors  as  proposed  by Korajczyk (1996 and Levine and Zervos (1998. Using panel regressions, our results show that  equity  integration  in  these  trading  blocs  is  driven  internally,  where  only  individual-market  volatility  and  economic  fundamentals  play  a  signiicant  role  in  the  process.  Intra-bloc  trade  is  found  to  enhance  regional  equity  market  integration,  supporting  the  notion that  regional  convergence  extends  beyond  the  trade  sector  that  is  promoted  in  the  trade agreements.  We  also  document  regime  shifting  effects  during  stock  market  crises,  where most  of  these  markets  became  strongly  integrated  after  a  regional  crisis,  but  integration was signiicantly weakened during a crisis that affected the world markets. Also, the level of equity market integration differs across trading blocs, where the blocs with a smaller number of country members are relatively more integrated. ";} // -->activate javascript

Quantifying the emissions reduction effectiveness and costs of oxygenated gasoline

International Nuclear Information System (INIS)

Lyons, C.E.

1993-01-01

During the fall, winter, and spring of 1991-1992, a measurement program was conducted in Denver, Colorado to quantify the technical and economic effectiveness of oxygenated gasoline in reducing automobile carbon monoxide (CO) emissions. Emissions from 80,000 vehicles under a variety of operating conditions were measured before, during, and after the seasonal introduction of oxygenated gasoline into the region. Gasoline samples were taken from several hundred vehicles to confirm the actual oxygen content of the fuel in use. Vehicle operating conditions, such as cold starts and warm operations, and ambient conditions were characterized. The variations in emissions attributable to fuel type and to operating conditions were then quantified. This paper describes the measurement program and its results. The 1991-1992 Colorado oxygenated gasoline program contributed to a reduction in carbon monoxide (CO) emissions from gasoline-powered vehicles. The measurement program demonstrated that most of the reduction is concentrated in a small percentage of the vehicles that use oxygenated gasoline. The remainder experience little or not reduction in emissions. The oxygenated gasoline program outlays are approximately $25 to $30 million per year in Colorado. These are directly measurable costs, incurred through increased government expenditures, higher costs to private industry, and losses in fuel economy. The measurement program determined the total costs of oxygenated gasoline as an air pollution control strategy for the region. Costs measured included government administration and enforcement, industry production and distribution, and consumer and other user costs. This paper describes the ability of the oxygenated gasoline program to reduce pollution; the overall cost of the program to government, industry, and consumers; and the effectiveness of the program in reducing pollution compared to its costs

Lambayeque Region marketing: Improving Incoming Tourism

Directory of Open Access Journals (Sweden)

Roger Pingo Jara

2012-12-01

Full Text Available Up to now, the marketing of the Lambayeque region as a tourist destination has been able to make important progress in the growth of domestic tourists flow. 40% of these tourists come from the capital, mostly they arrive in this region, mainly for business reasons. However, little progress is shown in relation to Incoming tourism, because from 100% of visitors who arrive to this touristic destination only 5% are of foreign origin.Furthermore, in 2011, from the total foreign tourists that visited the Moche Route - La Libertad region and Lambayeque region, 70% remained in the first one and only 30% visited both regions, completing the touristic circuit. The recommendations of the teachers of the Universidad del Pacífico, Universidad Esan and Centrum Católica, who have been interviewed are compared with the businessmen’s opinions in the region, showing the importance of targeting the tourism marketing strategy. Thus, it seeks to create value in different niches of the source markets, to prioritize potential tourists from brotherly countries, to link emotionally the tourist with the city, to build brands for each touristic product, to invest in highly specialized tourism and to improve significantly the clusters organization of the tourism sector in the region.We conclude that, in the region of Lambayeque, isolated efforts have been made regarding the incoming marketing, but, according to the needs, tastes and preferences of the potential tourist, this does not fulfill the international standards. This is demonstrated by the results achieved up to now—in terms of the foreign visitors’ number—. To that extent, It emphasizes the importance of the design and the implementation of a marketing plan connected with market reality.It should profit from the national brand and develop regional and local brand based on the international touristic demand-supply relation to market niches.

Developing the market for natural gas and biogas as a vehicle fuel on a regional level (MADEGASCAR)

2009-07-01

Although natural gas as a car fuel is a more environmentally clean alternative to gasoline or diesel and gas is considerable cheaper and much safer than other fuels, costumers are still suspicious of alternative fuels and vehicles. The main reasons are a lack of awareness and information on the consumer side, as well as a low information and acceptance level among car dealers and service stations. Therefore the MADEGASCAR project directly addresses major barriers by specific actions. The project MADEGASCAR (Market development for gas driven cars including supply and distribution of biogas), co-funded by the Intelligent Energy Europe programme of the European commission, aims at developing the market for natural gas vehicles by addressing target groups at the demand side (private car owners, fleet managers) as well as strengthening the supply and distribution infrastructure for Compressed Natural Gas (CNG) and Natural Gas Vehicles (NGVs) municipalities, car dealers, owners of fuel stations, natural gas and biogas suppliers) in 10 participating partner countries. The Unique Selling Point of the MADEGASCAR project is deployment in several regional areas instead of sole basic research. Country specific action plans, which are developed and implemented in the project, will have direct impact on regional markets but also affect car manufacturers and national regulations, resulting in long term changes. The main ambition of the MADEGASCAR project is to increase the number of gas vehicles in the partner regions by 50%.

We compare life cycle greenhouse gas (GHG) emissions from several light-duty passenger gasoline and plug-in electric vehicles (PEVs) across US counties by accounting for regional differences due to marginal grid mix, ambient temperature, patterns of vehicle miles traveled (VMT), and driving conditions (city versus highway). We find that PEVs can have larger or smaller carbon footprints than gasoline vehicles, depending on these regional factors and the specific vehicle models being compared. The Nissan Leaf battery electric vehicle has a smaller carbon footprint than the most efficient gasoline vehicle (the Toyota Prius) in the urban counties of California, Texas and Florida, whereas the Prius has a smaller carbon footprint in the Midwest and the South. The Leaf is lower emitting than the Mazda 3 conventional gasoline vehicle in most urban counties, but the Mazda 3 is lower emitting in rural Midwest counties. The Chevrolet Volt plug-in hybrid electric vehicle has a larger carbon footprint than the Prius throughout the continental US, though the Volt has a smaller carbon footprint than the Mazda 3 in many urban counties. Regional grid mix, temperature, driving conditions, and vehicle model all have substantial implications for identifying which technology has the lowest carbon footprint, whereas regional patterns of VMT have a much smaller effect. Given the variation in relative GHG implications, it is unlikely that blunt policy instruments that favor specific technology categories can ensure emission reductions universally.

The impact of gasoline price fluctuations on lodging demand for US brand hotels

International Nuclear Information System (INIS)

Walsh, Kate; Enz, Cathy A.; Canina, Linda

2004-01-01

Analyzing US brand hotels, over a 13-year period, this study provides empirical evidence of a significant negative relationship between gasoline prices and demand for certain lodging products, controlling for economic factors (i.e. gross domestic product and population density). Applying principles from microeconomic demand theory to the literature on gasoline price elasticities, consumer demographics and lodging demand, a set of hypotheses were devised to test the relationship between gasoline prices and lodging demand for specific hotel locations and price segments. Using fixed effects models, the results reveal that lodging demand decreases as gasoline prices rise in all segments except upper-upscale and all locations except urban areas. Hotels in midscale without food and beverage and economy market segments, in resort, suburban and highway locations, exhibit the greatest association between gasoline price shifts and demand. Implications of these findings are discussed for both hospitality research and practice. (Author)

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.

Recovery of gasoline

Energy Technology Data Exchange (ETDEWEB)

1937-02-27

The abstract describes a process for recovering a maximum quantity of commercial gasoline from a composite hydrocarbon stream containing hydrocarbons within and below the gasoline boiling range, including olefins. The hydrocarbon stream is separated into low vapor pressure gasoline and a gas fraction consisting of hydrocarbons of the 4 carbon atom group and some of the 3 carbon atom group. The gas fraction is subjected to a polymerization operation, characterized by utilizing the products of the polymerization procedure - both liquid polymers and unconverted gases - to increase the yield of gasoline and to adjust the low vapor pressure gasoline to the vapor pressure of commercial gasoline. A fraction of the gaseous products of the polymerization procedure are used for this purpose. The remainder of the gaseous products are recycled through the polymerization operation.

Asymmetry in retail gasoline and crude oil price movements in the United States. An application of hidden cointegration technique

International Nuclear Information System (INIS)

Honarvar, Afshin

2009-01-01

There is a common belief that gasoline prices respond more quickly to crude oil price increases than decreases. Some economists and politicians believe that asymmetry in oil and gasoline price movements is the outcome of a non-competitive gasoline market requiring that governments take policy action to address 'unfair pricing'. There is no consensus as to the existence, or nature, of the asymmetric relationship between prices of gasoline and crude oil. Much of this literature specifies asymmetry in the speed of adjustment and short-run adjustment coefficients. In contrast, Granger and Yoon's [Granger, C.W. and Yoon, G. 'Hidden Cointegration', University of California, San Diego, Department of Economics Working Paper, (2002).] Crouching Error Correction Model (CECM) identifies asymmetry of the cointegrating vectors between components (cumulative positive and negative changes) of the series. Applying the CECM to retail gasoline and crude oil prices for the U.S., we find that there is only evidence of cointegration between positive components of crude oil prices and negative components of gasoline prices. In contrast to the literature which attributes asymmetric price movements to market power of refiners, these findings suggest that gasoline prices -in the long run- are more influenced by the technological changes on the demand side than crude oil price movements on the supply side.

Gasoline sniffing multifocal neuropathy.

Burns, T M; Shneker, B F; Juel, V C

2001-11-01

The polyneuropathy caused by chronic gasoline inhalation is reported to be a gradually progressive, symmetric, sensorimotor polyneuropathy. We report unleaded gasoline sniffing by a female 14 years of age that precipitated peripheral neuropathy. In contrast with the previously reported presentation of peripheral neuropathy in gasoline inhalation, our patient developed multiple mononeuropathies superimposed on a background of sensorimotor polyneuropathy. The patient illustrates that gasoline sniffing neuropathy may present with acute multiple mononeuropathies resembling mononeuritis multiplex, possibly related to increased peripheral nerve susceptibility to pressure in the setting of neurotoxic components of gasoline. The presence of tetraethyl lead, which is no longer present in modern gasoline mixtures, is apparently not a necessary factor in the development of gasoline sniffer's neuropathy.

The economics of gasoline retailing : petroleum distribution and retailing issues in the U.S

Kleit, A.N. [Pennsylvania State Univ., University Park, PA (United States)

2005-03-31

Some of the controversies surrounding gasoline retailing prices in the United States were discussed with specific reference to zone pricing and non-price vertical restraints. Integrated refiners use a variety of often conflicting distribution methods to transport gasoline to consumers. The use of different retail provisions allows refiners to offer retail outlets to as many markets as possible, and these provisions have been the subject of antitrust scrutiny. Issues concerning refinery growth and capacity were reviewed along with brand management and federal standards. Various types of branded retail outlets were also discussed, along with company operated outlets and franchised dealer outlets. Issues concerning hypermarkets were examined and legal relationships between franchisers and franchisees in the petroleum industry were reviewed in relation to zone pricing. The motivation for non-price vertical restraints was considered, with reference to antitrust and anticompetitive behavior. It was suggested that the best way to analyze the gasoline sector is to examine the extent of margins in the sector. It was concluded that distribution channels help refiners market gasoline. Interactions between distribution channels can create competitive tensions in terms of brand free-riding and brand network operations. The use of price zones and non-price vertical restraints allow integrated refiners to offer retail distribution outlets across as many markets as possible. Antitrust scrutiny has not resulted in successful litigation as the refiners' actions are not expected to afflict consumers. 33 refs., 3 figs.

The Cushing OK Crude Oil Futures Price Pass - Through to New York Harbor Reformulated RBOB Regular Gasoline Futures Price

Directory of Open Access Journals (Sweden)

Chu V. Nguyen

2017-04-01

Full Text Available This study utilizes an Autoregressive Distributed Lag model to investigate the nature of crude oil futures price pass-through since 2006. The empirical results reveal a very high but incomplete short-run pass-through rate from the crude oil futures price to the gasoline futures price of 0.849298 with a corresponding negative long-run pass-through rate of -0.2440894. These empirical findings suggest that traders in the U.S. oil and gasoline futures markets overreact to fluctuations in the crude oil futures price as evidenced by subsequent corrections made over the sample period. The result of the bounds test for a long-term relationship between these two futures prices is inconclusive. The empirical findings further suggest that U.S. futures market traders considered futures prices of gasoline three weeks earlier in determining the current trading price while taking only one week to respond completely to the shock in the crude oil futures price.  The empirical findings of this investigation may address the core elements of the price dynamics of the crude oil and gasoline futures markets and advance inquiry into assessment tools that could manage a very complex market challenge, especially for policy makers in countries with transitional economies in Eastern Europe, Caucasus and Central Asia.

Long- and short-run price asymmetries and hysteresis in the Italian gasoline market

Bagnai, Alberto; Mongeau Ospina, Christian Alexander

2015-01-01

Using monthly data from 1994 to 2013 we study the long-run relation of the pre-tax retail prices of gasoline with crude price and the nominal exchange rate. We find a strongly significant long-run relation. We then use the nonlinear ARDL (NARDL) model to assess the asymmetries on both the short- and long-run elasticities, as well as the presence of hysteresis in the pricing behaviour. The estimation results confirm the presence of asymmetry in the long-run elasticities, with significant differences between the crude price and the exchange rate, as well as the presence of hysteresis in the relation between the retail price of gasoline and crude oil price. - Highlights: • The pass-through of crude oil prices and exchange rate into gasoline prices is examined. •We use an extended NARDL model to test for asymmetric reactions and hysteresis. • Asymmetric pricing behaviour features only in the long run. • The sign of the asymmetry differs between exchange rate and crude price changes. • The results are robust to the inclusion of several variables usually related to asymmetry

Szulczyk, Kenneth R.; McCarl, Bruce A.; Cornforth, Gerald

2010-01-01

This research examines in detail the technology and economics of substituting ethanol for gasoline. This endeavor examines three issues. First, the benefits of ethanol/gasoline blends are examined, and then the technical problems of large-scale implementation of ethanol. Second, ethanol production possibilities are examined in detail from a variety of feedstocks and technologies. The feedstocks are the starch/sugar crops and crop residues, while the technologies are corn wet mill, dry grind, and lignocellulosic fermentation. Examining in detail the production possibilities allows the researchers to identity the extent of technological change, production costs, byproducts, and GHG emissions. Finally, a U.S. agricultural model, FASOMGHG, is updated which predicts the market penetration of ethanol given technological progress, variety of technologies and feedstocks, market interactions, energy prices, and GHG prices. FASOMGHG has several interesting results. First, gasoline prices have a small expansionary impact on the U.S. ethanol industry. Both agricultural producers' income and cost both increase with higher energy prices. If wholesale gasoline is $4 per gallon, the predicted ethanol market penetration attains 53% of U.S. gasoline consumption in 2030. Second, the corn wet mill remains an important industry for ethanol production, because this industry also produces corn oil, which could be converted to biodiesel. Third, GHG prices expand the ethanol industry. However, the GHG price expands the corn wet mill, but has an ambiguous impact on lignocellulosic ethanol. Feedstocks for lignocellulosic fermentation can also be burned with coal to generate electricity. Both industries are quite GHG efficient. Finally, U.S. government subsidies on biofuels have an expansionary impact on ethanol production, but may only increase market penetration by an additional 1% in 2030, which is approximately 6 billion gallons.

Panovska, Vesna; Tomanovikj, Violeta

1999-01-01

With the phasing out of lead additives from gasoline, the interest for oxygenates as a gasoline components grows up. However, since these materials are not hydrocarbons their behaviour in terms of blending differs from the gasoline which consists of hydrocarbons only. Therefore, it is important to explain their role in blending gasolines according to European specification for motor fuels. It is important to emphasize the oxygenate contribution in production more clean gasoline. In this paper, the oxygenate types and there basic specification features followed by manufacture, laboratory testing and blending specifications with refinery components is presented. (Author)

Regional prices in the Swedish wood-fuel market

International Nuclear Information System (INIS)

Hillring, Bengt

1999-01-01

This paper analyses, through a statistical survey, the regional distribution of prices on the commercial wood-fuel market for district heating plants and the pellets market for single family houses. The existing market watch of the national Swedish wood-fuel market has been developed for both refined and unrefined wood-fuels. The last five years the trend for wood-fuel prices on the district heating market has been stable, with a slight increase in the price of refined wood-fuels. However, on the young and fast-growing household market for pellets, prices have increased 12% during the last three years. The distribution of prices for northern, middle and southern Sweden indicates differences within 5% between the regions. The limited price difference between Swedish regions are a product of a large domestic supply and an increasing trade among regions in Europe, putting pressure on prices. Regional differences, mirrored as transportation distances and local production costs are key factors that could explain this regional price variation. However, the development of a commercial market with less regulation tends to level out prices. Consumers on the household market purchase small quantities and do not have the same possibility as district heating companies to take advantage of the oversupply opportunity and thus face a faster price development. The weaker market position of the consumers also tends to give homogeneous prices between regions of the residential sector. (Author)

Volatilization of gasoline from soil

International Nuclear Information System (INIS)

Arthus, P.

1993-05-01

Gasoline contaminated soil threatens water resources and air quality. The extent of the threat depends on gasoline behavior in soil, which is affected by various mechanisms such as volatilization. To quantify volatilization, gasoline spills were simulated in the laboratory using a synthetic gasoline and three dry soils. Total gasoline and individual gasoline compound concentrations in soil were monitored as a function of depth and time. The time to reduce overall gasoline concentration in coarse sand, sandy loam, and silt loam to 40% of initial concentration, averaged between surface and a 200-mm depth, ranged from 0.25 d to 10 d. A wicking phenomenon which contributed to gasoline flux toward the atmosphere was indicated by behavior of a low-volatility gasoline compound. Based on separate wicking experiments, this bulk immiscible movement was estimated at an upward velocity of 0.09 m/d for Delhi sandy loam and 0.05 m/d for Elora silt loam. 70 refs., 24 figs., 34 tabs

Canadian retail petroleum markets study : a review of competitiveness in the Canadian refined petroleum marketing industry

International Nuclear Information System (INIS)

Ervin, M.J.

1997-01-01

A retail petroleum market study was conducted to provide a comprehensive overview of the competitiveness of the downstream petroleum industry in Canada, as well as to provide a foundation for effective policy development. A model which illustrates the interrelationships between the many stakeholders who receive revenue from the sale of gasoline was presented. It was shown that although there has been an upward trend in world crude prices since 1991, both refiners and marketers have experienced a decline in margins due to price competition at the rack and at the retail pump. Government intervention into petroleum marketing was considered to be of questionable value and a poor alternative to market-based regulation. In this study, 19 markets representing a broad range of conditions, were chosen for a detailed review of outlet economics. Market-by-market and regional comparisons of key competitiveness indicators were reviewed and discussed. Improving public understanding and awareness of competition in the petroleum marketing sector and developing cooperative industry research into marketing sector competitive issues were recommended. 7 refs., 15 tabs., 37 figs

2014-11-01

Sprague-Dawley rats were exposed via inhalation to vapor condensates of either gasoline or gasoline combined with various fuel oxygenates to assess potential neurotoxicity of evaporative emissions. Test articles included vapor condensates prepared from "baseline gasoline" (BGVC), or gasoline combined with methyl tertiary butyl ether (G/MTBE), ethyl t-butyl ether (G/ETBE), t-amyl methyl ether (G/TAME), diisopropyl ether (G/DIPE), ethanol (G/EtOH), or t-butyl alcohol (G/TBA). Target concentrations were 0, 2000, 10,000 or 20,000mg/mg(3) and exposures were for 6h/day, 5days/week for 13weeks. The functional observation battery (FOB) with the addition of motor activity (MA) testing, hematoxylin and eosin staining of brain tissue sections, and brain regional analysis of glial fibrillary acidic protein (GFAP) were used to assess behavioral changes, traditional neuropathology and astrogliosis, respectively. FOB and MA data for all agents, except G/TBA, were negative. G/TBA behavioral effects resolved during recovery. Neuropathology was negative for all groups. Analyses of GFAP revealed increases in multiplebrain regions largely limited to males of the G/EtOH group, findings indicative of minor gliosis, most significantly in the cerebellum. Small changes (both increases and decreases) in GFAP were observed for other test agents but effects were not consistent across sex, brain region or exposure concentration.

Replacing gasoline with corn ethanol results in significant environmental problem-shifting.

Science.gov (United States)

Yang, Yi; Bae, Junghan; Kim, Junbeum; Suh, Sangwon

2012-04-03

Previous studies on the life-cycle environmental impacts of corn ethanol and gasoline focused almost exclusively on energy balance and greenhouse gas (GHG) emissions and largely overlooked the influence of regional differences in agricultural practices. This study compares the environmental impact of gasoline and E85 taking into consideration 12 different environmental impacts and regional differences among 19 corn-growing states. Results show that E85 does not outperform gasoline when a wide spectrum of impacts is considered. If the impacts are aggregated using weights developed by the National Institute of Standards and Technology (NIST), overall, E85 generates approximately 6% to 108% (23% on average) greater impact compared with gasoline, depending on where corn is produced, primarily because corn production induces significant eutrophication impacts and requires intensive irrigation. If GHG emissions from the indirect land use changes are considered, the differences increase to between 16% and 118% (33% on average). Our study indicates that replacing gasoline with corn ethanol may only result in shifting the net environmental impacts primarily toward increased eutrophication and greater water scarcity. These results suggest that the environmental criteria used in the Energy Independence and Security Act (EISA) be re-evaluated to include additional categories of environmental impact beyond GHG emissions.

Trouble in your tank: What can be done about out-of-control gasoline prices?

Menzies, D.

2000-01-01

The recent increases in the price of automotive fuels, especially gasoline is discussed. The Canadian Automobile Association (CAA) makes several recommendation as to how the government might intervene to bring prices back down to a realistic level. First and foremost, the CAA recommends an outright gasoline tax cut, noting that tax on gasoline has increased from 1.5 cent to 10 cents a litre since 1885. The CAA also suggests that a minimum of 5 cents reduction in price would result if the GST were applied only on an ex-tax basis instead of being tacked on to the total pump price after federal and provincial taxes have been added, which in effect amounts to a tax on tax. The provinces could also help by cutting back on their gasoline taxes which range from a low of 9 cents in Alberta to a high of 16.5 cents in Newfoundland. It is noted that the Ottawa-based Canadian Petroleum Products Institute, which represents the major oil companies, does not support the CAA suggestions and dismisses concerns regarding the near-monopoly in the market held by a few major oil companies by saying that while there are admittedly fewer small independents in the market, competition from new larger entrants has actually increased. The Institute spokesman attributes the recent round of price increases as merely the results of world market forces (despite the fact that Canada is a net exporter of oil). At the same time, the Independent Retail Gasoline Merchant Association wants the government to conduct a fundamental review of the Competition Act, to harmonize Canadian laws with those of the United States, our largest trading partner. The Association believes that the Competition Bureau has evolved into a a quasi-judicial body, and is mired in red tape. The Association also suggests that in the meantime, the government should invoke the Energy Supplies Emergency Act to stop Big Oil's 'deceitful price gouging'

Gasoline from Wood via Integrated Gasification, Synthesis, and Methanol-to-Gasoline Technologies

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 study of Canadian retail gasoline prices

International Nuclear Information System (INIS)

Eckert, A.L.

1999-05-01

Retail gasoline pricing in Canadian markets was examined to demonstrate why retail prices tend to follow one of two distinct patterns and that neither pattern is observable in the wholesale price. In many cities, retail prices are more rigid than wholesale prices, while in other markets, retail prices follow a cyclic pattern not seen in wholesale prices. This study examined why constant prices are observed in some cities, while other cities have cyclic prices. Theoretical justification was given to the argument that prices will remain constant only in markets in which there are only few gasoline companies with a small number of stations, but a large per-station capacity. It was shown that when one firm operates significantly more stations than its rival, a constant cost equilibrium cannot be maintained. However, a cycle equilibrium can be constructed in this case, and also when the two companies are similarly sized. An initial examination of available price, cost and market structure data shows that there is a positive correlation between price stability and concentration. The response of retail prices to wholesale price movements in the presence of a retail price cycle was also examined through the use of a simple model based on the predictions of the above theory. Data for the city of Windsor, Ontario was used for the modelling approach. A new cycle is created by an increase in price whenever the distance between the previous retail price and the current wholesale prices is very small. Retail prices are more responsive to wholesale prices over the increasing portion of the cycle. It was shown that when the asymmetric error correction model of Borenstein, Cameron and Gilbert is estimated, it indicates a more rapid response to wholesale price increases than to decreases. 72 refs., 22 tabs., 8 figs

Highlights: • We chose 8-component hydrocarbon mixture as a model gasoline, and defined the molar mass of gasoline. • We proposed an evaporation model assuming a 2-component mixture of gasoline and ETBE. • We predicted the change in the vapor pressure of ETBE-blended gasoline by evaporation. • The vapor pressures were measured and compared as a means of verifying the model. • We presented the method for predicting flash points of the ETBE-blended gasoline. - Abstract: 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.

Countries differ considerably in terms of the price drivers pay for gasoline. This paper uses data for 132 countries for the period 1995–2008 to investigate the implications of these differences for the consumption of gasoline for road transport. To address the potential for simultaneity bias, we use both a country's oil reserves and the international crude oil price as instruments for a country's average gasoline pump price. We obtain estimates of the long-run price elasticity of gasoline demand of between − 0.2 and − 0.5. Using newly available data for a sub-sample of 43 countries, we also find that higher gasoline prices induce consumers to substitute to vehicles that are more fuel-efficient, with an estimated elasticity of + 0.2. Despite the small size of our elasticity estimates, there is considerable scope for low-price countries to achieve gasoline savings and vehicle fuel economy improvements via reducing gasoline subsidies and/or increasing gasoline taxes. - Highlights: ► We estimate the determinants of gasoline demand and new-vehicle fuel economy. ► Estimates are for a large sample of countries for the period 1995–2008. ► We instrument for gasoline prices using oil reserves and the world crude oil price. ► Gasoline demand and fuel economy are inelastic with respect to the gasoline price. ► Large energy efficiency gains are possible via higher gasoline prices

Examining the short-run price elasticity of gasoline demand in the United States

Science.gov (United States)

Brannan, Michael James

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.

Ethanol Demand in United States Gasoline Production

Energy Technology Data Exchange (ETDEWEB)

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.

Elfasakhany, Ashraf

2015-01-01

Highlights: • iso-Butanol–gasoline blends (iB) using up to 10 vol.% butanol were examined in SIE. • iB extensively decrease the greenhouse effect of SI engine. • iB without engine tuning led to a drop in engine performance at all speeds. • iB provide higher performance and lower CO and CO 2 emissions than n-butanol blends. • iB grant lower CO and UHC than gasoline at <2900 r/min, but overturn at >2900 r/min. - Abstract: Experimental investigation on pollutant emissions and performance of SI engine fueled with gasoline and iso-butanol–gasoline blends is carried out. Engine was operated at speed range of 2600–3400 r/min for each blend (3, 7 and 10 vol.% iso-butanol) and neat gasoline. Results declare that the CO and UHC emissions of neat gasoline are higher than those of the blended fuels for speeds less than or equal to 2900 r/min; however, for speeds higher than 2900 r/min, we have an opposite impact where the blended fuels produce higher level of CO and UHC emissions than the gasoline fuel. The CO 2 emission at using iso-butanol–gasoline blends is always lower than the neat gasoline at all speeds by up to 43%. The engine performance results demonstrate that using iso-butanol–gasoline blends in SI engine without any engine tuning lead to a drop in engine performance within all speed range. Without modifying the engine system, overall fuel combustion of iso-butanol–gasoline blends was quasi-complete. However, when engine system is optimized for blended fuels, iso-butanol has significant oxygen content and that can lead to a leaner combustion, which improves the completeness of combustion and therefore high performance and less emissions would be obtained. Finally, the performance and emissions of iso-butanol–gasoline blends are compared with those of n-butanol–gasoline blends at similar blended rates and engine working conditions. Such comparison is directed to evaluate the combustion dissimilarity of the two butanol isomers and also to

McPhail, Lihong Lu; Babcock, Bruce A.

2012-01-01

Despite a large number of studies that examine the influence of biofuels and biofuel policy on commodity prices, the impact of biofuel policy on commodity price variability is poorly understood. A good understanding of biofuel policy’s impact on price variability is important for mitigating food insecurity and assisting policy formation. We examine how U.S. ethanol policies such as the Renewable Fuel Standard (RFS) mandates and the blend wall affect the price variability of corn and gasoline. We first present an analytical and graphical framework to identify the effect and then use stochastic partial equilibrium simulation to measure the magnitude of the impacts. We show that RFS mandates and the blend wall both reduce the price elasticity of demand for corn and gasoline and therefore increase the price variability when supply shocks occur to the markets. This has important implications for policy actions with respect to maintaining or changing the current RFS mandates and/or blend wall in the US. -- Highlights: ► The RFS is found to lead to less elastic demand for corn and gasoline. ► Thus the RFS is also found to lead to more volatile corn and gasoline prices when supply shocks occur. ► The ethanol blend wall is found to lead to less elastic corn and gasoline demand. ► Thus the blend wall is also found to lead to more volatile corn and gasoline prices.

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.

Standby Gasoline Rationing Plan

1980-06-01

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)

Two features of gasoline and diesel markets make the choice of tax mechanism a unique problem. First, prices are very volatile. Second, demand for motor fuels is extremely inelastic. As a result, fuel expenditures vary substantially over time. Tying state revenues to these expenditures, as is the case with a sales tax, results in a volatile stream of revenue which imposes real costs on agents in an economy. On July 1, 2010, California enacted Assembly Bill x8-6, the “Gas Tax Swap”, increasing the excise tax and decreasing the sales tax on gasoline purchases. While the initial motivation behind the revenue neutral swap was to provide the state with greater flexibility within its budget, we highlight that this change has two potentially overlooked benefits; it reduces retail fuel price volatility and tax revenue volatility. Simulating the monthly fuel prices and tax revenues under alternative tax policies, we quantify the potential reductions in revenue volatility. The results reveal that greater benefits can be achieved by going beyond the tax swap and eliminating the gasoline sales tax entirely. - Highlights: • We examine how gasoline taxes affect government revenue volatility. • We simulate the impact of California's Gasoline Tax Swap policy. • Sales taxes are shown to magnify price volatility and government revenue volatility. • A pure excise tax policy results in less volatile fuel prices and state revenues. • We argue that reductions in both forms of volatility are welfare enhancing

This report is about the market for airline travel in northern New Mexico. Interest in developing a northern New Mexico regional airport has periodically surfaced for a number of years. The New Mexico State Legislature passed a memorial during the 1998 Second Session calling for the conduct of a study to determine the feasibility of building a new regional airport in NNM. This report is a study of the passenger market feasibility of such an airport. In addition to commercial passenger market feasibility, there are other feasibility issues dealing with siting, environmental impact, noise, economic impact, intermodal transportation integration, region-wide transportation services, airport engineering requirements, and others. These other feasibility issues are not analyzed in any depth in this report although none were discovered to be show-stoppers as a by-product of the authors doing research on the passenger market itself. Preceding the need for a detailed study of these other issues is the determination of the basic market need for an airport with regular commercial airline service in the first place. This report is restricted to an in-depth look at the market for commercial passenger air service in NNM. 20 figs., 8 tabs.

A field survey was conducted of oil shipment depots in Java and Bali islands owned by Indonesia's state-run oil company to study measures for reduction in greenhouse effect gas emissions. Studies were made on the grasp of the amount of the hydrocarbon vapor emitted into the air, the amount of the gasoline recovered in case of adopting the vapor emission preventive technology, equipment cost/operational cost, etc. Concretely, the following three were studied: change of the gasoline storage tank to the inner floating roof type, and prevention of evaporation loss at the time of receiving and breathing loss caused by temperature changes; replacement with the vapor recovery type loading arm to recover gasoline vapor generated at the time of shipment/filling, and installation of the vapor recovery unit to recover vapor as gasoline; vapor balance system to recover in underground tank the gasoline vapor generated at the time of filling gasoline at gas station. As a result of the study, the recovered gasoline amount was 66,393 Kl/y and the CO2 reduction amount was 14,474 t/y at oil shipment depots and approximately 650 gasoline stations in Jakarta and Surabaya.

Contract portfolio optimization for a gasoline supply chain

Science.gov (United States)

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

Impact of gasoline inhalation on some neurobehavioural characteristics of male rats

Background This paper examines closely and compares the potential hazards of inhalation of two types of gasoline (car fuel). The first type is the commonly use leaded gasoline and the second is the unleaded type enriched with oxygenate additives as lead substituent in order to raise the octane number. The impacts of gasoline exposure on Na+, K+-ATPase, superoxide dismutase (SOD), acetylcholinesterase (AChE), total protein, reduced glutathione (GSH), and lipid peroxidation (TBARS) in the cerebral cortex, and monoamine neurotransmitters dopamine (DA), norepinephrine (NE) and serotonin (5-HT) in the cerebral cortex, hippocampus, cerebellum and hypothalamus were evaluated. The effect of gasoline exposure on the aggressive behaviour tests was also studied. Results The present results revealed that gasoline inhalation induced significant fluctuations in the levels of the monoamine neurotransmitters in the studied brain regions. This was concomitant with a decrease in Na+, K+-ATPase activity and total protein content. Moreover, the group exposed to the unleaded gasoline exhibited an increase in lipid peroxidation and a decrease in AChE and superoxide dismutase activities. These physiological impairments were accompanied with a higher tendency towards aggressive behaviour as a consequence to gasoline inhalation. Conclusion It is concluded from the present work that chronic exposure to either the leaded or the unleaded gasoline vapours impaired the levels of monoamine neurotransmitters and other biochemical parameters in different brain areas and modulated several behavioural aspects related to aggression in rats.

Reformulated gasoline: Costs and refinery impacts

International Nuclear Information System (INIS)

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 Vulnerability of the Regional Labor Market

Full Text Available In the past decades, the European and Romanian economies have been strongly affected by major changes which have influenced also the labor market: the alert pace of the international economic integration, the creation of work division in order to protect some economic sectors, the accelerated development and implementation of new technologies, the increase of the demographic aging trends. In the context of the amplified labor force crisis, the present paper will analyze some dysfunctions which have affected especially the regional labor market: the chronic unemployment, the mismatch between the demand and the offer of jobs and the localized consequences of the labor migration. The approach on these aspects was done in a vaster context intended to analyze the regional labor market of Galati and Braila, starting from the existent imbalances on these markets. The present paper starts from the premise that the proposal of some measurements which should lead to a balancing of the regional working market, must take into account the way in which the direct actors involved are defining these obstacles and opportunities for professional (reinsertion. In order to highlight both the opinions and the perceptions of the participants on the labor market, the research had to take place on two levels: among the groups with a difficult position on the labor market and among the employers.

Light-duty gasoline vehicles have drawn public attention in China due to their significant primary emissions of particulate matter and volatile organic compounds (VOCs). However, little information on secondary aerosol formation from exhaust for Chinese vehicles and fuel conditions is available. In this study, chamber experiments were conducted to quantify the potential of secondary aerosol formation from the exhaust of a port fuel injection gasoline engine. The engine and fuel used are common in the Chinese market, and the fuel satisfies the China V gasoline fuel standard. Substantial secondary aerosol formation was observed during a 4-5hr simulation, which was estimated to represent more than 10days of equivalent atmospheric photo-oxidation in Beijing. As a consequence, the extreme case secondary organic aerosol (SOA) production was 426±85mg/kg-fuel, with high levels of precursors and OH exposure. The low hygroscopicity of the aerosols formed inside the chamber suggests that SOA was the dominant chemical composition. Fourteen percent of SOA measured in the chamber experiments could be explained through the oxidation of speciated single-ring aromatics. Unspeciated precursors, such as intermediate-volatility organic compounds and semi-volatile organic compounds, might be significant for SOA formation from gasoline VOCs. We concluded that reductions of emissions of aerosol precursor gases from vehicles are essential to mediate pollution in China. Copyright © 2017. Published by Elsevier B.V.

Leaded gasoline - an environmental problem

International Nuclear Information System (INIS)

Petrushevska, Ljubica

2001-01-01

In the European countries it is a clear trend towards the increasing consumption of unleaded gasolines. Driving force of this trend is, on the one hand the high toxicity of lead compounds and on the other, the necessity of purification of exhaust gases by catalytic converters, for which the lead represent a catalyst poison. In Macedonia, the limit lead content in the leaded gasolines is relatively high (0,6 g/l), as well as the consumption of the leaded gasolines. Rapid and complete transition to unleaded gasolines can be realized by the concept of step by step reduction of lead in our gasolines. (Original)

In South Africa, a country that is rich in natural resources, gross domestic product has risen steadily since the historic elections in April 1994. In 1995, foreign trade made up almost 50 per cent of the country's gross national product. Unemployment and concurrent shortage of skilled labour are some of the major challenges that still exist for South Africa. Sasol is one of South Africa's top 10 private companies. It was founded in 1950; it supplies 44 per cent of South Africa's liquid fuel needs and produces most of the feedstocks used by the chemical and plastics industries in the country. The company is known for innovative technologies, such as the Sasol Synthol Process. It produces high-quality synthetic fuels such as petrol, diesel, kerosene, gas and furnace oils. The unique Sasol Synthol Process was described. Coal is put under high pressure and high temperature in the presence of steam and oxygen, is converted to crude gas, purified by removing sulfur and is then used in the production of gasoline, diesel and other fuels. The process also yields 120 other chemical products for domestic and international markets. 3 refs., 5 figs

Evidence of asymmetric behavioral responses to changes in gasoline prices and taxes for different fuel types

International Nuclear Information System (INIS)

Bajo-Buenestado, Raúl

2016-01-01

Using monthly data from the Spanish gasoline retail market we explore asymmetries in consumers’ behavioral responses to changes in gasoline prices and taxes. In particular, we are interested in investigating whether an increase in gasoline taxes has a more negative impact on the demand than a –similar in magnitude– increase in the “pre-tax” price of gasoline for different fuel types. We estimate fuel consumers’ responses using a rich set of robust panel data models considering potential dynamic effects and endogeneity problems. We find evidence to confirm the existence of asymmetric responses for the demand of unleaded fuels and agricultural diesel fuel. However we cannot support this statement for the regular diesel case: for this fuel both the tax-exclusive price and the tax elasticities are roughly the same. This result agrees with the fact that “diesel drivers” tend to be better informed about changes in both fuel prices and taxes. Some implications in terms of fiscal policy and pollution and climate change policy are also discussed. - Highlights: •Provide evidence of asymmetric responses of gasoline demand due to changes in prices and taxes. •Identify differences in the elasticity of the demand of diesel fuel and unleaded gasoline. •Perform robustness checks considering dynamic effects and IV regression. •Provide some policy recommendations for future gasoline tax changes.

The inhalation toxicity of an ethanol-gasoline mixture was investigated in rats. Groups of 15 male and 15 female rats were exposed by inhalation to 6130 ppm ethanol, 500 ppm gasoline or a mixture of 85% ethanol and 15% gasoline (by volume, 6130 ppm ethanol and 500 ppm gasoline), 6 h a day, 5 days per week for 4 weeks. Control rats of both genders received HEPA/charcoal-filtered room air. Ten males and ten females from each group were killed after 4 weeks of treatment and the remaining rats were exposed to filtered room air for an additional 4 weeks to determine the reversibility of toxic injuries. Female rats treated with the mixture showed growth suppression, which was reversed after 4 weeks of recovery. Increased kidney weight and elevated liver microsomal ethoxyresorufin-O-deethylase (EROD) activity, urinary ascorbic acid, hippuric acid and blood lymphocytes were observed and most of the effects were associated with gasoline exposure. Combined exposure to ethanol and gasoline appeared to exert an additive effect on growth suppression. Inflammation of the upper respiratory tract was observed only in the ethanol-gasoline mixture groups, and exposure to either ethanol and gasoline had no effect on the organ, suggesting that an irritating effect was produced when the two liquids were mixed. Morphology in the adrenal gland was characterized by vacuolation of the cortical area. Although histological changes were generally mild in male and female rats and were reversed after 4 weeks, the changes tended to be more severe in male rats. Brain biogenic amine levels were altered in ethanol- and gasoline-treated groups; their levels varied with respect to gender and brain region. Although no general interactions were observed in the brain neurotransmitters, gasoline appeared to suppress dopamine concentrations in the nucleus accumbens region co-exposed to ethanol. It was concluded that treatment with ethanol and gasoline, at the levels studied, produced mild, reversible

Reformulated gasoline: lessons from America

Regulating fuel quality is one of the few politically feasible options for improving air quality in the short and medium term. This book explores and studies the reformulated gasoline programme currently underway in the USA. Despite the smoothness of the initial implementation of the programme, difficulties may arise in the future. It is concluded that reformulated gasoline prices are more independent of crude oil price changes than conventional unleaded gasoline. Finally, the study suggests that refiners will not reap great profit from investment in the supply of reformulated gasoline because of government restrictions. (UK)

Oxygenates to hike gasoline price

International Nuclear Information System (INIS)

Anon.

1992-01-01

This paper reports that cost of achieving required US gasoline formulations this winter in Environmental Protection Agency carbon monoxide (CO) nonattainment areas could reach 3-5 cents/gal, an Energy Information Administration analysis has found. EIA says new winter demand for gasoline blending oxygenates such as methyl tertiary butyl ether (MTBE) or ethanol created by 190 amendments to the Clean Air Act (CAA) will exceed US oxygenate production by 140,000-220,000 b/d. The shortfall must be made up from inventory or imports. EIA estimates the cost of providing incremental oxygenate to meet expected gasoline blending demand likely will result in a price premium of about 20 cents/gal of MTBE equivalent over traditional gasoline blend octane value. That cost likely will be added to the price of oxygenated gasoline

Market penetration of biodiesel and ethanol

Science.gov (United States)

Szulczyk, Kenneth Ray

This dissertation examines the influence that economic and technological factors have on the penetration of biodiesel and ethanol into the transportation fuels market. This dissertation focuses on four aspects. The first involves the influence of fossil fuel prices, because biofuels are substitutes and have to compete in price. The second involves biofuel manufacturing technology, principally the feedstock-to-biofuel conversion rates, and the biofuel manufacturing costs. The third involves prices for greenhouse gas offsets. The fourth involves the agricultural commodity markets for feedstocks, and biofuel byproducts. This dissertation uses the Forest and Agricultural Sector Optimization Model-Greenhouse Gas (FASOM-GHG) to quantitatively examine these issues and calculates equilibrium prices and quantities, given market interactions, fossil fuel prices, carbon dioxide equivalent prices, government biofuel subsidies, technological improvement, and crop yield gains. The results indicate that for the ranges studied, gasoline prices have a major impact on aggregate ethanol production but only at low prices. At higher prices, one runs into a capacity constraint that limits expansion on the capacity of ethanol production. Aggregate biodiesel production is highly responsive to gasoline prices and increases over time. (Diesel fuel price is proportional to the gasoline price). Carbon dioxide equivalent prices expand the biodiesel industry, but have no impact on ethanol aggregate production when gasoline prices are high again because of refinery capacity expansion. Improvement of crop yields shows a similar pattern, expanding ethanol production when the gasoline price is low and expanding biodiesel. Technological improvement, where biorefinery production costs decrease over time, had minimal impact on aggregate ethanol and biodiesel production. Finally, U.S. government subsidies have a large expansionary impact on aggregate biodiesel production. Finally, U.S. government

Turn of the century refueling: A review of innovations in early gasoline refueling methods and analogies for hydrogen

International Nuclear Information System (INIS)

Melaina, Marc W.

2007-01-01

During the first decades of the 20th century, a variety of gasoline refueling methods supported early US gasoline vehicles and successfully alleviated consumer concerns over refueling availability. The refueling methods employed included cans, barrels, home refueling outfits, parking garage refueling facilities, mobile stations, hand carts and curb pumps. Only after robust markets for gasoline vehicles had been firmly established did the gasoline service station become the dominant refueling method. The present study reviews this history and draws analogies with current and future efforts to introduce hydrogen as a fuel for vehicles. These comparisons hold no predictive power; however, there is heuristic value in an historical review of the first successful and large-scale introduction of a vehicle fuel. From an energy policy perspective, these comparisons reinforce the importance of a long-term and portfolio approach to support for technology development and innovation

Water consumption in the production of ethanol and petroleum gasoline.

Wu, May; Mintz, Marianne; Wang, Michael; Arora, Salil

2009-11-01

We assessed current water consumption during liquid fuel production, evaluating major steps of fuel lifecycle for five fuel pathways: bioethanol from corn, bioethanol from cellulosic feedstocks, gasoline from U.S. conventional crude obtained from onshore wells, gasoline from Saudi Arabian crude, and gasoline from Canadian oil sands. Our analysis revealed that the amount of irrigation water used to grow biofuel feedstocks varies significantly from one region to another and that water consumption for biofuel production varies with processing technology. In oil exploration and production, water consumption depends on the source and location of crude, the recovery technology, and the amount of produced water re-injected for oil recovery. Our results also indicate that crop irrigation is the most important factor determining water consumption in the production of corn ethanol. Nearly 70% of U.S. corn used for ethanol is produced in regions where 10-17 liters of water are consumed to produce one liter of ethanol. Ethanol production plants are less water intensive and there is a downward trend in water consumption. Water requirements for switchgrass ethanol production vary from 1.9 to 9.8 liters for each liter of ethanol produced. We found that water is consumed at a rate of 2.8-6.6 liters for each liter of gasoline produced for more than 90% of crude oil obtained from conventional onshore sources in the U.S. and more than half of crude oil imported from Saudi Arabia. For more than 55% of crude oil from Canadian oil sands, about 5.2 liters of water are consumed for each liter of gasoline produced. Our analysis highlighted the vital importance of water management during the feedstock production and conversion stage of the fuel lifecycle.

Japan's refiner/marketers headed for major shakeout

International Nuclear Information System (INIS)

Anon.

1996-01-01

Japan's downstream oil industry is in a state of crisis and headed for a major shakeout. The major catalyst for this was a dramatic deregulation step during April 1996 that allowed refined petroleum product imports by non-refiners. The move, together with a sharp drop in refining margins, falling retail gasoline prices, and a service station sector on the brink of collapse, are all leading to massive changes in the way the country's refiners and marketers do business. This paper reviews the collapse of corporate profits during this period of deregulation; the development of a new price system geared toward bringing the prices of gasoline, fuel oil, and kerosene into line with each other to offset the fall in gasoline prices; and industry restructuring including mergers, acquisitions, and marketing consolidation. The paper then makes predictions on the outcome of these changes on the Japanese oil industry

It was asserted that no other region in the world can match the long-term market opportunities that China and Southeast Asia promise. The forces driving the economic development in Southeast Asia were described, including the great potential the region holds for the petrochemical industry. Graphs showing total polyethylene production vs. demand for year 2005 were included as illustrative examples. By 2005, China is projected to be importing almost one-half of the products it consumes. Every country with excess capacity will supply China with polyethylene. The political uncertainties that makes doing business in the region a high risk undertaking were reviewed, along with other risks relevant to the petrochemical industry such as (1) high capital costs, (2) over-building to the point that there is more supply than demand for the product, (3) low-cost producers may drive down prices to maintain market share, and (4) the uncertain nature of projections regarding economic growth and (5) inflated estimates of demand for petrochemicals. 1 tab., 4 figs

Competition in the U. K. retail petrol market 1960-73

Energy Technology Data Exchange (ETDEWEB)

Lowe, J F

1976-03-01

Changes in the gasoline retailing industries of England since 1960 are discussed, and the causative factors are analyzed. Competition for oil consumers in the United Kingdom was at the retail level, making it difficult for monopoly activity to materialize and causing a shift in the market structure since 1964. The shift in structure was a result of a few new independent wholesaling firms and numerous subsidiaries of international companies entering the market rather than any action of the Monopolies Commission. Gasoline is not a typical good. On the supply side it is a joint product and firms can, at a cost, interchange one product for another in promotion or alter the price of one to affect the price of another. Demand for gasoline, on the other hand, is relatively price inelastic because of the lack of product substitutes and the fact that gasoline represents only about 30% of the total cost of a car. Company price cuts in the 1960's were usually made by new firms breaking into the market. There was very little price competition among the established firms, and the retailers accounted for most price variations. New firms also used distribution and site ownership to gain inroads into the market as well as advertising and promotional techniques like trading stamps. (22 references) (DCK)

An experimental investigation was conducted to determine the emissions characteristics of higher alcohols and gasoline (UTG96) blends. While lower alcohols (methanol and ethanol) have been used in blends with gasoline, very little work has been done or reported on higher alcohols (propanol, butanol and pentanol). Comparisons of emissions and fuel characteristics between higher alcohol/gasoline blends and neat gasoline were made to determine the advantages and disadvantages of blending higher alcohols with gasoline. All tests were conducted on a single-cylinder Waukesha Cooperative Fuel Research engine operating at steady state conditions and stoichiometric air-fuel (A/F) ratio. Emissions test were conducted at the optimum spark timing-knock limiting compression ratio combination for the particular blend being tested. The cycle emission [mass per unit time (g/h)] of CO, CO 2 and organic matter hydrocarbon equivalent (OMHCE) from the higher alcohol/gasoline blends were very similar to those from neat gasoline. Cycle emissions of NO x from the blends were higher than those from neat gasoline. However, for all the emissions species considered, the brake specific emissions (g/kW h) were significantly lower for the higher alcohol/gasoline blends than for neat gasoline. This was because the blends had greater resistance to knock and allowed higher compression ratios, which increased engine power output. The contribution of alcohols and aldehydes to the overall OMHCE emissions was found to be minimal. Cycle fuel consumption (g/h) of higher alcohol/gasoline blends was slightly higher than with neat gasoline due to the lower stoichiometric A/F ratios required by the blends. However, the brake specific fuel consumption (g/kW h) for the blends was significantly lower than that for neat gasoline. (Author)

Scenario of the emerging shift from gasoline to LPG fuelled cars in Ghana: A case study in Ho Municipality, Volta Region

2012-01-01

The use of LPG as automotive fuel is on the increase worldwide. In developing countries such as Ghana, the rudimental way of operating LPG cars is of a national concern since there is no clear cut framework within which they function. This paper presents a scenario of development from conversion of gasoline to LPG fuelling system in cars in Ho, Ghana. Data were collected through survey (100 questionnaires), in-depth interviews (2), Focus Group Discussions (3) and direct observations. The result shows LPG conversion is carried out by the local informally trained mechanics especially for Taxis because of its low consumption resulting in more profit. Conversion takes 1–2 day with an average estimated cost of GH□ 450 cedis ($300). The LPG policy in Ghana focuses on domestic purposes hence the fuel being heavily subsidised. Challenges' being faced by the autogas market in Ghana includes; no clear cut policy, low number of refuelling stations, lack of standard conversion and installation kits and unprofessional LPG installers. In order for government to benefit from LPG as automotive fuel, coherent autogas policy should be formulated ensuring the availability of the LPG with price affordability as in the case of gasoline and diesel. - Highlights: ► Cars are converted to LPG system locally because of economic gains relative to emission reduction. ► LPG fuelled cars makes twice profit as compared to gasoline cars. ► Conversion to LPG system takes 1–2 day with an average cost of GH 450 cedis ($300). ► LPG policy in Ghana focus on domestic purposes not for commercial hence heavily subsidised. ► Ghana Government should formulate clear policy on LPG use in cars.

Full Text Available We use the Labor Office data for the regions of the Czech Republic to investigate some of the structural features of the respective labor markets. We build our approach on the matching function of the search model of the labor market. In the paper we show how the regional labor markets differ with respect to vacancies, unemployment, matches between unemployed and vacancies, probability of finding a job and labor market tightness. We also demonstrate how these characteristics evolved over time. We show that the labor markets were really hit the hardest several years after the great recession began to affect the Czech Republic. We go on to estimate the matching function for the respective regional labor markets and show that the sensitivity of the probability of finding a job to the labor market tightness generally increased over time, which we interpret as a positive sign. We set our results in the framework of some of the earlier work which has been done. With all the data and estimates used we are able to pinpoint the most troubled regions as far as the structural features of the labor market are concerned.

Recent progress in gasoline surrogate fuels

Petroleum-derived gasoline is currently the most widely used fuel for transportation propulsion. The design and operation of gasoline fuels is governed by specific physical and chemical kinetic fuel properties. These must be thoroughly understood in order to improve sustainable gasoline fuel technologies in the face of economical, technological, and societal challenges. For this reason, surrogate mixtures are formulated to emulate the thermophysical, thermochemical, and chemical kinetic properties of the real fuel, so that fundamental experiments and predictive simulations can be conducted. Early studies on gasoline combustion typically adopted single component or binary mixtures (n-heptane/isooctane) as surrogates. However, the last decade has seen rapid progress in the formulation and utilization of ternary mixtures (n-heptane/isooctane/toluene), as well as multicomponent mixtures that span the entire carbon number range of gasoline fuels (C4–C10). The increased use of oxygenated fuels (ethanol, butanol, MTBE, etc.) as blending components/additives has also motivated studies on their addition to gasoline fuels. This comprehensive review presents the available experimental and chemical kinetic studies which have been performed to better understand the combustion properties of gasoline fuels and their surrogates. Focus is on the development and use of surrogate fuels that emulate real fuel properties governing the design and operation of engines. A detailed analysis is presented for the various classes of compounds used in formulating gasoline surrogate fuels, including n-paraffins, isoparaffins, olefins, naphthenes, and aromatics. Chemical kinetic models for individual molecules and mixtures of molecules to emulate gasoline surrogate fuels are presented. Despite the recent progress in gasoline surrogate fuel combustion research, there are still major gaps remaining; these are critically discussed, as well as their implications on fuel formulation and engine

Regional live cattle prices are decomposed into two components: (a) a trend common to all regional cattle price series and (b) regional deviations or price dynamics around that trend. Tests are developed to determine if market factors are related to the regional price deviations around a common trend. Slaughter volume, distance between a market and the next closest, and forward contract deliveries are significantly related to price deviations from the estimated common trend.

Gasoline surrogate modeling of gasoline ignition in a rapid compression machine and comparison to experiments

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

Lastewka, W.

2003-11-01

The House of Commons Standing Committee on Industry, Science and Technology has reviewed the data on retail, rack and crude gasoline prices in Canada in response to soaring prices. Prices were compared to those in the United States and elsewhere. The Committee looked at all possible explanations for the most recent increase in gasoline prices and has concluded that the recent increase in the price of gasoline was the result of industry's competitive reactions to a series of international crises and abnormally cold weather in North America. No evidence indicated anticompetitive conduct on the part of the industry, nor was there evidence of abusive behaviour on the part of vertically integrated suppliers in the form of squeezing retail margins to eliminate or discipline independent retailers. The Committee relied on data collected and published by the industry. It would have preferred an independent source, but none was available. The Committee recommended that the Government of Canada create and fund a Petroleum Monitoring Agency to collect and disseminate price data on crude oil, refined petroleum products, and retail gasoline for all relevant North American markets. The agency will report to Parliament on an annual basis for 3 years. The report will include information on the competitive aspects of the petroleum sector in Canada. refs., tabs., figs

Future vehicles will be required to improve their efficiency, reduce both regulated and CO{sub 2} emissions, and maintain acceptable driveability, safety, and noise. To achieve this overall performance, they will be configured with more advanced hardware, sensors, and control technologies that will also enable their operation on a broader range of fuel properties. Fuel flexibility has already been demonstrated in previous studies on a compression ignition bench engine and a demonstration vehicle equipped with an advanced engine management system, closed-loop combustion control, and air-path control strategies. An unresolved question is whether engines of this sort can also operate on market gasoline while achieving diesel-like efficiency and acceptable emissions and noise levels. In this study, a compression ignition bench engine having a higher compression ratio, optimised valve timing, advanced engine management system, and flexible fuel injection could be operated on a European gasoline over full to medium part loads. The combustion was sensitive to EGR rates, however, and optimising all emissions and combustion noise was a considerable challenge at lower loads. (orig.)

2015-12-01

Full Text Available The market of public catering is an important element of the national economy which has been dynamically developing. As in any other country, Russian citizens spend some part of their income on eating out, however, this part is rather small (for example, according to official statistics as of 2005, the average resident of Russia spent 9.5 times less money on catering than the resident of the US, and 4 times less than the German resident. This gap as well as significant differences in the degree of individual business development in different regions, testify to the enormous prospects of this market both in quantitative and geographic, and qualitative aspect. According to the expert opinion, the current macroeconomic situation unfavorable for many sectors of the economy can become a driver for the growth of the catering market, to be exact – for the fast food segment, which in the previous crisis of 2008-2009 showed a positive dynamics and opened up new opportunities for business. In this article we investigated the dynamics of the catering market development, and evaluated the contribution of the industry to Russian GDP. We studied the regional market conditions in the context of districts, regions and socio-economic indicators, such as the turnover of catering, the number of enterprises, the number of seats, and the area of cafes. The article describes the method of classifying the catering enterprises, highlights the specific features of the Russian market and the structure of the largest network companies. We studied the expert opinions regarding the medium-term development of the industry, the market trend of eating out and the possible fundamental changes associated with an increase in the quality of business processes, service and marketing communications.

The Changbai Mountains is rich in the resources of green food. At present, the low marketization of green food resources in the forest region of the Changbai Mountains becomes the bottleneck to restrict the benign development of its green food industry. With huge market demands at home and abroad, it is the urgent problem how to improve marketization process of green food resources and transfer the resources superiority into the market superiority in the region. According to the investigation, this paper analyzed the status quo and the cause of formation of low-marketization with the method of combining comparative research and practice research. It pointed out that necessary condition of marketization of green food resources in the forest region, such as strategy, economic environment, marketization allocation of sci-tech resources, etc. should be established. Furthermore, the concrete strategies of marketization of green food resources in the region such as market location, strategies of objective markets, combined strategy of marketing, etc. were advanced.

This report reviews the chemistry of sulfate salts dissolved in ethanol and gasoline, potential sources of sulfate salts in ethanol and gasoline, the history of consumer vehicle issues with sulfate salt deposits in the early 2000s, and the corresponding changes to the denatured fuel ethanol specification. Recommendations for future research are provided. During a period of rapid market expansion in 2004-05, issues were reported with vehicles running on E10 provided by certain suppliers in some markets. It was commonly believed that these vehicle problems were caused by sulfate salts precipitating from the fuel. Investigators identified sodium sulfate, and in one case also ammonium sulfate, as the predominate salts found in the engines. Several stakeholders believed the issue was excess sulfate ions in the ethanol portion of the E10, and in 2005 the ASTM specification for ethanol (D4806) was modified to include a 4-part per million (ppm) limit on sulfate ions. While there have been no further reports of consumer vehicle issues, the recently approved increase of ethanol in gasoline from 10 to 15 volume percent has resulted in renewed interest in the sulfate ion concentration in fuel ethanol. This report reviews published data on the solubility of sulfate salts in ethanol. The possible sources of sulfate anions and charge balancing cations (such as sodium) in fuel ethanol and petroleum derived blendstocks are discussed. Examination of historical information on the consumer vehicle issues that occurred in 2004-2005 reveals that a source of sodium or ammonium ions, required for the formation of the observed insoluble salts, was never identified. Recommendations for research to better understand sulfate salt solubility issues in ethanol, hydrocarbon blendstocks, and ethanol-gasoline blends are presented.

Impact of a new gasoline benzene regulation on ambient air pollutants in Anchorage, Alaska

Science.gov (United States)

Yano, Yuriko; Morris, Stephen S.; Salerno, Christopher; Schlapia, Anne M.; Stichick, Mathew

2016-05-01

The purpose of this study was to quantify the impact of a new U.S. Environmental Protection Agency (EPA) standard that limits the amount of benzene allowed in gasoline on ambient benzene concentrations. This new standard, together with two companion regulations that limit cold-temperature automotive emissions and the permeability of portable fuel containers, was expected to lower the levels of ambient benzene and other volatile organic compounds (VOCs) nationwide. In this study the impact of the gasoline benzene standard was evaluated in Anchorage, Alaska in a two-phase ambient air monitoring study conducted before and after the new gasoline standard was implemented. Gasoline sold by Anchorage retailers was also evaluated in each phase to determine the content of benzene and other gasoline components. The average benzene content in Anchorage gasoline was reduced by 70%, from 5.05% (w/w) to 1.53% (w/w) following the implementation of the standard. The annual mean ambient benzene concentration fell by 51%, from 0.99 ppbv in Phase 1 to 0.49 ppbv in Phase 2. Analysis suggests the change in gasoline benzene content alone reduced benzene emissions by 46%. The changes in toluene, ethylbenzene, and xylene content in gasoline between Phase 1 and 2 were relatively small and the differences in the mean ambient concentrations of these compounds between phases were modest. Our results suggest that cold winter communities in high latitude and mountainous regions may benefit more from the gasoline benzene standard because of high benzene emissions resulting from vehicle cold start and a tendency to develop atmospheric stagnation conditions in the winter.

Very small babies born in tertiary centers fare better than outborn babies referred for tertiary care after birth. Viewing the 1001-1500 gm regional cohort of fetuses as a potential "market" for center delivery, and measuring a center's penetration into this market, quantitates how well a center draws to itself these small, high-risk fetuses for delivery. An Illinois center's annual penetration rate into its regional market for the years 1973-1983 is presented and significant increases are found. The penetration rates of nine Illinois perinatal centers are calculated and wide discrepancies are found. Defining a high-risk regional cohort as a market stresses a perinatal center's obligation to its region. The penetration rate into a defined market measures how well a center fulfills this obligation.

Combustion Kinetic Studies of Gasolines and Surrogates

KAUST Repository

Javed, Tamour

2016-11-01

Future thrusts for gasoline engine development can be broadly summarized into two categories: (i) efficiency improvements in conventional spark ignition engines, and (ii) development of advance compression ignition (ACI) concepts. Efficiency improvements in conventional spark ignition engines requires downsizing (and turbocharging) which may be achieved by using high octane gasolines, whereas, low octane gasolines fuels are anticipated for ACI concepts. The current work provides the essential combustion kinetic data, targeting both thrusts, that is needed to develop high fidelity gasoline surrogate mechanisms and surrogate complexity guidelines. Ignition delay times of a wide range of certified gasolines and surrogates are reported here. These measurements were performed in shock tubes and rapid compression machines over a wide range of experimental conditions (650 – 1250 K, 10 – 40 bar) relevant to internal combustion engines. Using the measured the data and chemical kinetic analyses, the surrogate complexity requirements for these gasolines in homogeneous environments are specified. For the discussions presented here, gasolines are classified into three categories: (i)\\tLow octane gasolines including Saudi Aramco’s light naphtha fuel (anti-knock index, AKI = (RON + MON)/2 = 64; Sensitivity (S) = RON – MON = 1), certified FACE (Fuels for Advanced Combustion Engines) gasoline I and J (AKI ~ 70, S = 0.7 and 3 respectively), and their Primary Reference Fuels (PRF, mixtures of n-heptane and iso-octane) and multi-component surrogates. (ii)\\t Mid octane gasolines including FACE A and C (AKI ~ 84, S ~ 0 and 1 respectively) and their PRF surrogates. Laser absorption measurements of intermediate and product species formed during gasoline/surrogate oxidation are also reported. (iii)\\t A wide range of n-heptane/iso-octane/toluene (TPRF) blends to adequately represent the octane and sensitivity requirements of high octane gasolines including FACE gasoline F and G

The majority of reported cases of gasoline intoxication involves inhalation or percutaneous absorption. Data are scarce on complications and outcomes after gasoline poisoning by oral ingestion. The major cause of mortality and morbidity associated with the ingestion of gasoline is related to pulmonary aspiration. Despite the high frequency of the ingestions, there is little documentation of nonpulmonary toxic effects of gasoline. After ingestion, the principal toxicity is aspiration pneumonia, but any documented extra pulmonary manifestations of this condition may be important in the overall management of these patients. We are reporting a rare case of pancytopenia along with aspiration pneumonia and multisystem organ failure in a 58-year-old male after prolonged intentional ingestion of gasoline. To our knowledge, this is the only reported case of gasoline toxicity causing pancytopenia.

Full Text Available The maturity of competitiveness and its dynamics is a focus of assessing state decisions aimed for economic growth. To estimate the maturity of the competitive environment, researchers apply different methods. However, synthesis of the existing approaches has revealed the comparability of various approaches to the assessment of the maturity of the competitive environment. The authors have proposed a methodology of comprehensive assessment, which includes the estimation of market concentration, diverging trends of revenue and costs, survey of entrepreneurs. The comparison of the estimations employs a three-stage model of data processing. This model consequently compares the characteristics of markets maturity obtained while implementing the above-mentioned approaches. We have tested the methodology using the materials of the research performed in 2015–2017 on the territory of Sverdlovsk Region. Our study has shown the following essential results. Firstly, we have classified socially important and priority markets of Sverdlovsk Region by the level of competitiveness development. Most of the markets are estimated as the markets with missing and low competition. The majority of them represent the segments of the education market. The authors also grouped highly competitive markets, which include the retail market, the market of overland carriage of passengers, the market of communication services and the market of cultural services. Moreover, we specified the group of markets with a moderate competition. This group consists of the market of housing and communal services, social services market, and the market of medical products. Secondly, we confirmed that the assessment of a competitive situation using one of the approaches is imprecise. Both in 2015 and in 2016, there is no convergence in estimates received by statistical and survey methods for the market of social services and certain segments of the education market.

Over decades, large amounts of the neurotoxin lead were released into the European environment, mostly from gasoline lead additives. Emissions were growing unabatedly until the 1970s, when a series of regulations on the allowed gasoline lead content were adopted. As a result, in the 1990s most gasoline contained only small amounts of lead. We have examined this case of environmental pollution and regulation, and performed a retrospective assessment of the extent of regional-scale lead pollution and the effects of gasoline lead regulations in Europe. With the help of a regional climate model, NCEP re-analyses, spatially disaggregated lead emissions from road traffic and point sources, and various local data, the airborne pathways and depositions of gasoline lead in Europe since 1958 were reconstructed. It turns out that this approach is successful in describing the time-variable, spatially disaggregated deposition of gasoline lead. Additional data from analyses of concentrations in biota, including plant leaves, mussels and human blood, allows an assessment about the impact of the lead phase-out on the quality of the environment. Demonstrating the success of the lead policies, concentrations in leaves and human blood have steadily declined since the early 1980s. At the same time, the economic repercussions that had been feared did not emerge. Instead, the affected mineral oil and car manufacturing industries in Germany (our case-study) were able to deal with the effort without incurring significant extra costs. We suggest that our method of quantitatively reconstructing and anticipating fluxes and depositions of substances can be applied to other relevant substances as well, such as, for example, Persistent Organic Pollutants, radioactive substances or pollens.

Ignition studies of two low-octane gasolines

KAUST Repository

Javed, Tamour

2017-07-24

Low-octane gasolines (RON ∼ 50–70 range) are prospective fuels for gasoline compression ignition (GCI) internal combustion engines. GCI technology utilizing low-octane fuels has the potential to significantly improve well-to-wheel efficiency and reduce the transportation sector\\'s environmental footprint by offsetting diesel fuel usage in compression ignition engines. In this study, ignition delay times of two low-octane FACE (Fuels for Advanced Combustion Engines) gasolines, FACE I and FACE J, were measured in a shock tube and a rapid compression machine over a broad range of engine-relevant conditions (650–1200 K, 20 and 40 bar and ϕ = 0.5 and 1). The two gasolines are of similar octane ratings with anti-knock index, AKI = (RON + MON)/2, of ∼ 70 and sensitivity, S = RON–MON, of ∼ 3. However, the molecular compositions of the two gasolines are notably different. Experimental ignition delay time results showed that the two gasolines exhibited similar reactivity over a wide range of test conditions. Furthermore, ignition delay times of a primary reference fuel (PRF) surrogate (n-heptane/iso-octane blend), having the same AKI as the FACE gasolines, captured the ignition behavior of these gasolines with some minor discrepancies at low temperatures (T < 700 K). Multi-component surrogates, formulated by matching the octane ratings and compositions of the two gasolines, emulated the autoignition behavior of gasolines from high to low temperatures. Homogeneous charge compression ignition (HCCI) engine simulations were used to show that the PRF and multi-component surrogates exhibited similar combustion phasing over a wide range of engine operating conditions.

Full Text Available In the article, the relevant problem of increasing the regional budget revenues is investigated. The subject matter of the research is the securities market as a mechanism for the redistribution of financial resources. The purpose of the research is justification of the effective scheme feasible in the current environment of the interaction of the securities market and the regional budget. In the study of the above-mentioned subject, the hypothesis of a close relationship between state and non-state finance system was taken as a basis. The theoretical principle of the research supports the theory of the stock market; to achieve the purpose, the institutionally-functional approach to the study of state finances is applied. As the result of the research, possible common grounds of the securities market and the regional financial system are identified; the reserve of improving efficiency of the securities market in the Western Siberia regions are revealed; the model reflecting the dependence of tax revenues from the pace of regional economic development is constructed; promising areas for development of the securities market for the benefit of the regional economy and regional financial system are formulated; the possible effect from the development of regional securities market on regional budget revenues is estimated. The results mentioned above are recommended to be apllied when developing regional financial policies and programmes of region socio-economic development. A long-term stimulation of the growth in incomes of regional budgets is a very complex process, but with the proper elaboration of organizational issues, the implementation of the proposed scheme for interaction of the securities market and the regional financial system is capable to provide a steady increase in tax revenue in the short term and alleviate the problem of financing costs of the regional budget.

A Regional Multi-permit Market for Ecosystem Services

Science.gov (United States)

Bernknopf, R.; Amos, P.; Zhang, E.

2014-12-01

Regional cap and trade programs have been in operation since the 1970's to reduce environmental externalities (NOx and SOx emissions) and have been shown to be beneficial. Air quality and water quality limits are enforced through numerous Federal and State laws and regulations while local communities are seeking ways to protect regional green infrastructure and their ecosystems services. Why not combine them in a market approach to reduce many environmental externalities simultaneously? In a multi-permit market program reforestation (land offsets) as part of a nutrient or carbon sequestration trading program would provide a means to reduce agrochemical discharges into streams, rivers, and groundwater. Land conversions also improve the quality and quantity of other environmental externalities such as air pollution. Collocated nonmarket ecosystem services have societal benefits that can expand the crediting system into a multi-permit trading program. At a regional scale it is possible to combine regulation of water quality, air emissions and quality, and habitat conservation and restoration into one program. This research is about the economic feasibility of a Philadelphia regional multi-permit (cap and trade) program for ecosystem services. Instead of establishing individual markets for ecosystem services, the assumption of the spatial portfolio approach is that it is based on the interdependence of ecosystem functions so that market credits encompasses a range of ecosystem services. Using an existing example the components of the approach are described in terms of scenarios of land portfolios and the calculation of expected return on investment and risk. An experiment in the Schuylkill Watershed will be described for ecosystem services such as nutrients in water and populations of bird species along with Green House Gases. The Philadelphia regional market includes the urban - nonurban economic and environmental interactions and impacts.

Gordian, Mary Ellen; Stewart, Alistair W; Morris, Stephen S

2010-01-01

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

Realizing the greater risk by the increase in the level of financial market integration, this study investigates the dynamic of international and regional stock markets co-movement among Asian countries with the world leading market, the US. The data utilized in this study comprises of weekly closing prices for four stock indices, that consists of two developing markets (Malaysia and China) and two developed markets (Japan and the US), and encompasses the period from January 1996 to December 2012. Multivariate Generalized Autoregressive Conditional Heteroscedasticity (MGARCH) model with the BEKK parameterization is employed to investigate the mean and volatility spillover effects among the selected stock indices. The results show significant mean spillover not only from the larger developed markets to smaller developing markets but also from the smaller developing markets to larger developed markets. Volatility spillover between the developed markets is found to be smaller than that between the developing markets. Conditional correlations among the stock markets are found to increase over the sample period. The findings of significant mean and volatility spillovers are considered as bad news for international investors as it reduces the benefit from portfolio diversification but act as useful information for investors to be more aware in diversifying their investment or stock selection.

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%.

Nicol, C.J.

2003-01-01

Fluctuations in the world price of oil, the concern with greenhouse gas emissions and the efforts to revive the 1997 Kyoto Protocol have resulted in renewed interest in the estimation of elasticities of demand for gasoline. In this paper, a complete system of demand equations is estimated, including an equation for the demand for gasoline. Canadian family expenditure (FAMEX) and United States consumer expenditure (CEX) survey data are used. Household-level data permits estimation of elasticities for various household groups. Also, differences in demand responsiveness to own-price and income changes are estimated for different regions in Canada and the United States. Demand is found to be own-price and income inelastic, on the whole, as reported in earlier studies. There is also variation in these elasticities across regions of Canada and the United States. However, larger differences are observed with respect to household size and housing tenure, than to region of residence

Since the early 1970s, there has been a worldwide upsurge in the price of energy and in particular of gasoline. Therefore, demand functions for energy and its components like gasoline have received much attention. However, since confidence in the estimated demand functions is important for use in policy and forecasting, following [Amarawickrama, H.A., Hunt, L.C., 2008. Electricity demand for Sri Lanka: A time series analysis. Energy Economics 33, 724-739], this paper estimates the demand for gasoline is estimated with five alternative time series techniques with data from Fiji. Estimates with these alternative techniques are very close, and thus increase our confidence in them. We found that gasoline demand is both price and income inelastic.

Gasoline, ingested intentionally or accidentally, is toxic. The majority of reported cases of gasoline intoxication involve oral ingestion or inhalation. Data are scarce on complications and outcomes following hydrocarbon poisoning by intravenous injection. Following a suicide attempt by intravenous self-injection of 10 ml of gasoline, a 26-year-old medical student was admitted to the intensive care unit (ICU) with hemoptysis, symptoms of acute respiratory failure, chest pain, and severe abdominal cramps. Gas exchange was severely impaired and a chest x-ray indicated chemical pneumonitis. Initial treatment consisted of mechanical ventilation, supportive hyperventilation, administration of nitrogen oxide (NO), and prednisone. Unfortunately, the patient developed multi-organ dysfunction syndrome (MODS) complicated by life-threatening severe vasoplegia within 24 hours after gasoline injection. High doses of vasopressors along with massive amounts of parenteral fluids were necessary. Despite fluid replacement, renal function worsened and required hemofiltration on 5 sequential days. After 12 days of intensive care management, the patient recovered completely and was discharged to a psychiatric care facility. Intravenous gasoline injection causes major injury to the lungs, the organ bearing the first capillary bed encountered. Treatment of gasoline poisoning is symptomatic because no specific antidote is available. Early and aggressive supportive care may be conducive to a favorable outcome with minimal residual pulmonary sequelae.

Natural gas liquids markets in the United States

International Nuclear Information System (INIS)

Anderson, W.E.

1991-01-01

Changes in natural gas liquids (NGL) markets in the USA, brought about primarily by environmental issues and actions, are reviewed. Three aspects of the Clean Air Act amendments are exerting a powerful influence on NGL product demands. Regulatory limits on Reed vapor pressure (RVP) reduce the amount of evaporative hydrocarbon emissions, and lower-RVP gasoline is leaner in the more volatile hydrocarbons. This means primarily a lower n-butane content, and during the 1990-91 summer blending season it is estimated that half of total U.S. gas plant production of n-butane was being eliminated from the traditional refinery blending market. N-butane prices fell, making n-butane attractive as a petrochemical feedstock. Regulatory requirements for reformulated and oxygenated gasolines, for which methyl tertiary butyl ether (MTBE) will be the largest single source of oxygenate, have increased demand for NGL butanes used as the basic raw material in MBTE manufacture. This demand should increase enough to absorb all the n-butane dislodged from the gasoline blending market. The amendments also specify that in selected metropolitan areas having severe air quality problems, an alternative fuels program must be established. In the alternative fuels market, propane is already well-established due to favorable economics and proven performance, and significant new demand for propane in metropolitan markets is expected. Ethylene, the basic raw material for plastics manufacture, is mainly derived from NGLs and the continued strong demand for plastics will have a positive effect on the NGL market. NGL product demand profiles and projections are presented in graph form for ethane, propane, butanes, and pentanes plus. 4 figs

Regional markets with agricultural workforce based on Labour offices' data

Full Text Available The changes in Czech agriculture over the past twenty years have had their impact on the agricultural labour market, too. The regional differentiation of the chances of applicants on the labour market as well as the agricultural enterprises’ chances of hiring employees fitting their requirements, are, among others, influenced by the specific conditions of agricultural production. The aim of this paper pertains to two basic problem areas: first, the differentiation of respective regions based on the number of agricultural applicants and job vacancies, and second, the identification of disequilibrium on the agricultural labour market. The latter is based on a theoretical framework defined by approaches in economy dealing with labour market equilibrium. Due to the unavailability of economic data (including wages, economic performance, etc. on the regional level, authors develop their own methodological approach, based on the number of applicants per job vacancy. A database of applicants and vacancies available from the Labour Offices is used as a source for the analysis and interpretation of data, enabling us to study the agricultural labour market not only sector-wise but also region-wise.

The crude production, quality, oil product demand, imports and refinery capabilities of U.S. Petroleum Administration for Defence District Five (PADD -V) were discussed and the distinguishing characteristics of the PADD-V market were summarized. The seven states which make up US PADD-V include Alaska, Hawaii, Washington, Oregon, California, Nevada and Arizona. PADD-V is a unique petroleum market with strong ties to Canada. The only crude oil pipeline serving the area is the TransMountain pipeline which connects Alberta producers with British Columbia and Washington State. PADD-V has emerged as a significant customer of Canadian crude, and methyl tertiary butyl ether (MTBE) to California refiners producing reformulated gasoline. PADD-V refining capacity utilization is high and generally more sophisticated than refineries elsewhere, with higher actual throughput and product output slate higher in value. The large majority of PADD-V output is reformulated gasoline and diesel, aviation fuels, and conventional transport fuels. It is believed that as product demand continues, PADD-V may become an even more significant importer of refined product. The proposed ban on MTBE blending in gasoline could have a major impact on refinery operations and product trade. 14 figs

Life cycle assessment of gasoline and diesel

International Nuclear Information System (INIS)

Furuholt, Edgar

1995-01-01

A life cycle assessment (LCA) has been carried out to compare production and use of three different fuel products: regular gasoline, gasoline with MTBE and diesel. The study quantifies energy consumption and emissions through the production chain and assesses the potential impacts to the environment. Some of the methodological problems performing the LCA are discussed. The study indicates that production of gasoline with MTBE has potentially larger environmental impacts than production of regular gasoline, caused by the extra facilities for production of MTBE. The study also shows that the results are highly sensitive to the actual product specifications and assumptions that are made. Different product specifications can therefore lead to other conclusions. The results also indicate that production of diesel leads to significantly lower potential impacts than the gasolines

Investigation of fatalities due to acute gasoline poisoning.

Science.gov (United States)

Martínez, María A; Ballesteros, Salomé

2005-10-01

This paper presents a simple, rapid, reliable, and validated method suited for forensic examination of gasoline in biological samples. The proposed methodology has been applied to the investigation of four fatal cases due to gasoline poisoning that occurred in Spain in 2003 and 2004. Case histories and pathological and toxicological findings are described in order to illustrate the danger of gasoline exposure under several circumstances. Gasoline's tissular distribution, its quantitative toxicological significance, and the possible mechanisms leading to death are also discussed. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography (GC) with flame-ionization detection, and confirmation was performed using GC-mass spectrometry in total ion chromatogram mode. m,p-Xylene peak was selected to estimate gasoline in all biological samples. Gasoline analytical methodology was validated at five concentration levels from 1 to 100 mg/L. The method provided extraction recoveries between 77.6% and 98.3%. The limit of detection was 0.3 mg/L, and the limit of quantitation was 1.0 mg/L. The linearity of the blood calibration curves was excellent with r2 values of > 0.997. Intraday and interday precisions had a coefficient of variation inhalation of gasoline vapor inside a small enclosed space. Case 3 is a death by recreational gasoline inhalation in a male adolescent. Heart blood concentrations were 28.4, 18.0, and 38.3 mg/L, respectively; liver concentrations were 41.4, 52.9, and 124.2 mg/kg, respectively; and lung concentrations were 5.6, 8.4, and 39.3 mg/kg, respectively. Case 4 was an accidental death due to gasoline ingestion of a woman with senile dementia. Peripheral blood concentration was 122.4 mg/L, the highest in our experience. Because pathological findings were consistent with other reports of gasoline intoxication and constituents of gasoline were found in the body, cause of death was attributed to acute gasoline

1991-01-01

The late 1980s saw an astonishing turnaround in the Asian oil market. After years of stagnation, three main factors - economic dynamism, lower oil prices and reduced government regulation of the market - resulted in a consumption surge that surprised even those analysts who had predicted such a recovery. The chronically capacity-surplus refining industry saw a leap in profitability, and new construction began. Rapid demand growth spread from the middle distillates to such formerly depressed products as gasoline and fuel oil, and naphtha markets began to expand again as the petrochemical industry resumed rapid growth. At the same time that demand has been rising and demand patterns have been shifting, other changes have begun. A new environmental awareness has taken root in Asia, and new environmental standards are being set almost daily, not only in the richer countries of East Asia, but also in many of the region's developing nations. Unfortunately, traditional sources of low-sulphur oil for power generation may be limited in the coming decade. Despite many new discoveries within the region, Asian crude availability is shrinking, both in terms of availability on the international market and in terms of percentage contribution to regional oil demand. After years of decreasing reliance, the region will face rapid increases in imports from the Persian Gulf in the 1990s. (author). 16 figs, 4 tabs

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 age, gender, and race from 2004Ð2008, 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 younger...

Higher prices at Canadian gas pumps: international crude oil prices or local market concentration? An empirical investigation

International Nuclear Information System (INIS)

There is little consensus on whether higher retail gasoline prices in Canada are the result of international crude oil price fluctuations or local market power exercised by large vertically-integrated firms. I find that although both increasing local market concentration and higher average monthly wholesale prices are positively and significantly associated with higher retail prices, wholesale prices are more important than local market concentration. Similarly, crude oil prices are more important than the number of local wholesalers in determining wholesale prices. These results suggest that movements in gasoline prices are largely the result of input price fluctuations rather than local market structure. (author)

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.

Evaluation for leaded and unleaded Gasoline as Hazardous Waste

International Nuclear Information System (INIS)

Abou El Naga, H.H.

1999-01-01

With the phase out of alkyl lead compounds as necessary additives for gasoline in order to raise its octane number , the alternative is to reformulate gasoline to have nearly same octane number but with other chemical structures. Such reformulated gasoline (RFG) is found to contain higher aromatics, benzene, iso paraffins, in comparison to leaded gasoline. Additionally, this reformulated gasoline can also contain oxygenated additives. Accordingly, this paper is aiming at evaluation of emitted hazardous chemical compounds from car engines at fuel combustion. Role of chemical structures for reformulated gasoline in emission of volatile organic compounds (VOC) and poisoning materials are considered

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. Copyright © 2014 The Authors. Published by Elsevier Inc.

Natural gas in Asia: Trade, markets and regional institutions

International Nuclear Information System (INIS)

Vivoda, Vlado

2014-01-01

Natural gas trade in Asia has been dominated by long-established market structures, under which liquefied natural gas (LNG) has remained indexed based on the price of crude oil. High transaction costs in the region in recent years imply that the regional market is sub-optimally organized. Since 2010, the continued prevalence of oil-indexation has had the most adverse effect on Japan, the world’s largest LNG importer. In response, Japan implemented several strategies to challenge traditional LNG pricing mechanisms in the region and ultimately reduce transaction costs. Japan’s efforts include an increase in the share of spot and short-term purchases, sourcing new supplies from the United States under alternative pricing arrangements and driving regional buyer cooperation. This paper evaluates the potential effect of Japan’s LNG strategy on regional pricing in the broader institutional context, arguing that LNG pricing in the region will only partially shift away from oil-indexation by the end of the decade. While recent cooperation among regional LNG importers indicates that there may be scope for change in the regional institutional setting, the degree of cooperation is insufficient to have a profound effect on regional pricing. - Highlights: • Sub-optimal natural gas market outcomes in Asia since 2010. • Asian buyers have challenged oil-indexation in the region. • Concrete evidence of Japan-led buyer cooperation since 2013. • Pricing will only partially shift from oil-indexation by 2020. • Security of supply remains a top policy priority

Full Text Available This paper investigates the role of exports in the regional markets on the performance of supply chain. The study first determines critical variables affecting exports for entering into the regional markets and then measures the effects of these variables on the effectiveness of supply chain performance. The study uses two questionnaires, one for measuring the effects of various factors on export development and the other for measuring supply chain performance in Likert scale. Cronbach alpha for the mentioned questionnaires were calculated as 0.84 and 0.78, respectively. The population of the survey includes all small and medium enterprises active in city of Tehran, Iran and the study selects a sample of 250 people as a sample size. Using factor analysis, the study has determined seven factors including product development, government support, strategic orientation, customer satisfaction, competitive pressures, organizational capability and distribution strategies for entry into regional markets. In addition, the implementation of structural equation modeling has disclosed that product development and distribution strategies maintained the highest impact on export activities.

Coglianese, John; Davis, Lucas W; Kilian, Lutz; Stock, James H

2015-01-01

Traditional least squares estimates of the responsiveness of gasoline consumption to changes in gasoline prices are biased toward zero, given the endogeneity of gasoline prices. A seemingly natural solution to this problem is to instrument for gasoline prices using gasoline taxes, but this approach tends to yield implausibly large price elasticities. We demonstrate that anticipatory behavior provides an important explanation for this result. We provide evidence that gasoline buyers increase g...

GTLine – Gasoline as a potential CN suppressant for GTL

KAUST Repository

Reijnders, Jos; Boot, Michael; Johansson, Bengt; de Goey, Philip

2018-01-01

The main driver to investigate low temperature combustion concepts, such as partially premixed combustion (PPC), is the promise of low particulate matter (PM) and nitric oxide (NOx) emissions. A critical prerequisite for PPC is to temporally isolate the fuel injection and combustion events. In practice, exhaust gas recirculation (EGR) is applied in order to sufficiently extend the ignition delay to that effect. Hereby, in general, higher EGR rates are necessary for fuels with higher cetane numbers (CN). Against this background, the objective of this paper is to investigate the efficacy, with respect to PM-NOx emissions and engine efficiency, of gasoline as a potential gas-to-liquid (GTL) CN suppressant in various dosages. The performance of the resulting GTLine blend will be evaluated under PPC operating conditions in a heavy-duty direct-injected diesel engine. Setting aside for a moment any potential practical issues (e.g., flash point, vapor pressure) that fall outside the scope of this study, our data suggest that blending gasoline to otherwise high CN GTL appears to be a promising route to improve not only the efficiency, but also PM and NOx emissions, particularly when operating in PPC mode. Interestingly, this benefit is notwithstanding the high aromaticity of the gasoline compared to GTL. Given the ongoing dieselization trend and associated surplus of gasoline in many regions, notably Europe, along with the fact that the cost price of gasoline is significantly lower than that of GTL, the proposed GTLine approach promises to be a cost effective way to accommodate GTL in a world wherein low temperature combustion concepts, such as PPC, appear to be really taking off.

Sra, Kanwartej S.; Thomson, Neil R.; Barker, Jim F.

2013-07-01

One pore volume of unactivated sodium persulfate was delivered into an emplaced gasoline residual source zone at CFB Borden. Concentrations of inorganic species (S2O82 -, SO42 -, 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 > 10 months 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 M indicated persulfate consumption during oxidation of gasoline compounds or degradation due to the interaction with aquifer materials. M 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.

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

Phase-out of leaded gasoline: a prescription for Lebanon

International Nuclear Information System (INIS)

2000-01-01

Full text.Lead is a toxic heavy metal. Nevertheless, it has been mined and used for more than 800 years. Among the different contemporary sources of lead pollution, emissions from the combustion of leaded gasoline is of particular concern, as it can constitutes more than 90 percent of total lead emissions into the atmosphere in congested urban areas. Concentrations of lead in air and blood are strongly correlated with gasoline lead content and traffic volume. As a result of the increasing awareness about the dangers of lead to human health and the measures to manage urban air pollution, the use of leaded gasoline has been decreasing worldwide. In Lebanon, in the absence of policies to reduce the use of lead in gasoline or to favor the use of unleaded gasoline, leaded gasoline is the predominant grade. The objective of this research work is to analyze the current status of gasoline, and to assess the feasibility and prospect of such action. For this purpose, background information are presented, data about gasoline usage and specifications have been collected, field measurements have been performed and a public survey has been conducted. The comparison of the expected cost savings from phasing out leaded gasoline with the potential costs indicates that such action is economically highly justified. If effective regulatory measures are undertaken, leaded gasoline can be phased-out immediately without a significant cost

Asymmetric Price Responses of Gasoline Stations. Evidence for Heterogeneity of Retailers

This paper studies asymmetric price responses of individual firms, via daily retail prices of almost all gasoline stations in the Netherlands and suggested prices of the five largest oil companies over more than two years. I find that 38% of the stations respond asymmetrically to changes in the spot market price. Hence, asymmetric pricing is not a feature of the market as a whole, but of individual firms. For asymmetrically pricing stations, the asymmetry is substantial directly after a change but disappears after one or two days. I study station-specific characteristics and conclude that asymmetric pricing seems to be a phenomenon that is randomly distributed across stations. I also find that none of the five largest oil companies adjust their suggested prices asymmetrically.

The worldwide LPG industry continues to expand faster than the petroleum industry -- 4%/year for LPG vs. 2%/year for petroleum in 1995 and less than 1%/year in the early 1990s. This rapid expansion of LPG markets is occurring in virtually every region of the world, including such developing countries as China. The Far East is the focus of much of the LPG industry's attention, but many opportunities exist in other regions such as the Indian subcontinent, Southeast Asia, and Latin America. The investment climate is improving in all phases of downstream LPG marketing, including terminaling, storage, and wholesale and retail distribution. The world LPG supply/demand balance has been relatively tight since the Gulf War and should remain so. Base demand (the portion of demand that is not highly price-sensitive) is expanding more rapidly than supplies. As a result, the proportion of total LPG supplies available for price-sensitive petrochemical feedstock markets is declining, at least in the short term. The paper discusses importers, price patterns, world LPG demand, world LPG supply, US NGL supply, US gas processing, ethane and propane supply, butane, isobutane, and natural gasoline supply, and US NGL demand

New evidence on the asymmetry in gasoline price: volatility versus margin?

This paper examines recent evidence on the role that gasoline margins and volatility play in the asymmetric response of gasoline prices to changes in oil prices at different stages of distribution process. In a regression model with margins, we find that margins are statistically significant in explaining asymmetry between crude oil and spot gasoline prices, spot gasoline prices and wholesale gasoline prices, and wholesale gasoline prices and retail prices. In a regression model with input volatility, we find evidence that volatility is responsible for asymmetry between wholesale gasoline prices and retail gasoline prices. When both, gasoline margins and gasoline volatility are included in the regression, we find evidence supporting margins, the search theory, volatility, the oligopolistic coordination theory and an explanation of asymmetry.

An agent-based model to study market penetration of plug-in hybrid electric vehicles

International Nuclear Information System (INIS)

Eppstein, Margaret J.; Grover, David K.; Marshall, Jeffrey S.; Rizzo, Donna M.

2011-01-01

A spatially explicit agent-based vehicle consumer choice model is developed to explore sensitivities and nonlinear interactions between various potential influences on plug-in hybrid vehicle (PHEV) market penetration. The model accounts for spatial and social effects (including threshold effects, homophily, and conformity) and media influences. Preliminary simulations demonstrate how such a model could be used to identify nonlinear interactions among potential leverage points, inform policies affecting PHEV market penetration, and help identify future data collection necessary to more accurately model the system. We examine sensitivity of the model to gasoline prices, to accuracy in estimation of fuel costs, to agent willingness to adopt the PHEV technology, to PHEV purchase price and rebates, to PHEV battery range, and to heuristic values related to gasoline usage. Our simulations indicate that PHEV market penetration could be enhanced significantly by providing consumers with ready estimates of expected lifetime fuel costs associated with different vehicles (e.g., on vehicle stickers), and that increases in gasoline prices could nonlinearly magnify the impact on fleet efficiency. We also infer that a potential synergy from a gasoline tax with proceeds is used to fund research into longer-range lower-cost PHEV batteries. - Highlights: → We model consumer agents to study potential market penetration of PHEVs. → The model accounts for spatial, social, and media effects. → We identify interactions among potential leverage points that could inform policy. → Consumer access to expected lifetime fuel costs may enhance PHEV market penetration. → Increasing PHEV battery range has synergistic effects on fleet efficiency.

Full Text Available The paper is result of research different cross-border electricity trading mechanisms impact. Focus is on investments in generation and transmission power system facilities in regional market. Assumptions include efficient market coupling mechanism (with more bidding zones, use of additional investment indicators (like social welfare and congestion cost and security of supply issues (capacity mechanisms. There is discussion on cost benefits analysis for particular market participants and there is possibility of risk reduction for regional power system expansion. It is shown current state-of-the-art, problems and trends in solving some aspects of market integration and investment issues. In some cases smaller and well defined bidding areas are absolutely essential in order to ensure system security and economic efficiency. There is no single criterion for power system expansion but it is possible to use combination of incentive schemes and possible through one index for cross-border trade. Risk management for cross-border electricity trading through several areas needs to be upgraded with use of financial transmission rights like weighted average area prices, respectively. Regional power system security is closely associated with timely investments in energy supply in line with economic development and environmental needs. Security of supply indicator is deriving an estimation of security of supply improvement from the market based simulation results when a generation or transmission investment project is implemented. All researched makes market integration and investments in Europe more efficient and gives more correct signals to market participants in regional market.

Quantities of Interest in Jet Stirred Reactor Oxidation of a High-Octane Gasoline

KAUST Repository

Chen, Bingjie

2017-03-28

This work examines the oxidation of a well-characterized, high-octane-number FACE (fuel for advanced combustion engines) F gasoline. Oxidation experiments were performed in a jet-stirred reactor (JSR) for FACE F gasoline under the following conditions: pressure, 10 bar; temperature, 530-1250 K; residence time, 0.7s; equivalence ratios, 0.5, 1.0, and 2.0. Detailed species profiles were achieved by identification and quantification from gas chromatography with mass spectrometry (GC-MS) and Fourier transform infrared spectrometry (FTIR). Four surrogates, with physical and chemical properties that mimic the real fuel properties, were used for simulations, with a detailed gasoline surrogate kinetic model. Fuel and species profiles were well-captured and-predicted by comparisons between experimental results and surrogate simulations. Further analysis was performed using a quantities of interest (QoI) approach to show the differences between experimental and simulation results and to evaluate the gasoline surrogate kinetic model. Analysis of the multicomponent surrogate kinetic model indicated that iso-octane and alkyl aromatic oxidation reactions had impact on species profiles in the high-temperature region;. however, the main production and consumption channels were related to smaller molecule reactions. The results presented here offer new insights into the oxidation chemistry of complex gasoline fuels and provide suggestions for the future development of surrogate kinetic models.

Methanol has become an alternative fuel for gasoline, which is facing a rapidly rising world demand with a limited oil supply. Methanol-gasoline has been used in China, but phase stability and vapor lock still need to be resolved in methanol-gasoline applications. In this paper, a series of tartaric esters were synthesized and used as phase stabilizers and saturation vapor pressure depressors for methanol-gasoline. The results showed that the phase stabilities of tartaric esters for methanol-gasoline depend on the length of the alkoxy group. Several tartaric esters were found to be effective in various gasoline-methanol blends, and the tartaric esters display high capacity to depress the saturation vapor pressure of methanol-gasoline. According to the results, it can be concluded that the tartaric esters have great potential to be bifunctional gasoline-methanol additives.

Evaluating the Impact of Regional Marketing Projects on the Development of Regions from Different Stakeholder Perspectives

Directory of Open Access Journals (Sweden)

Kunze Kim-Kathrin

2014-01-01

Full Text Available In the competition for economically attractive stakeholders, regions have to implement strategies to gain and adhere those interest groups. Empirical studies concerning the migration motivations show that it is not only labor market but also soft locational factors of the social environment, nature and landscape that are of high importance: A majority of the population is willing to move or rather stay at a special place because of such soft locational factors. This study examines the impact of regional marketing projects on the development of regions from the perspectives of inhabitants and tourists as well as general attributes to measure a region’s attractiveness from the perspective of high potentials. We argue that those projects that fit to the region and its unique selling propositions contribute to positioning and building location brand value. We show that projects have a socio-economic effect on the attitude towards regions and contribute to building location brand value. An analysis of group differences shows that the project influence on the region and region attractiveness are perceived in significantly different manner depending on the knowledge level of the stakeholder group. Consequently, one should increase the awareness of marketing activities and regions and focus on soft locational factors while establishing and positioning a region brand.

ECONOMICS OF TOMATO MARKETING IN ASHANTI REGION, GHANA

Directory of Open Access Journals (Sweden)

Camillus Abawiera Wongnaa

2014-02-01

Full Text Available The perishable nature of most agricultural produce and the concomitant need for effective marketing outlets carries along huge economic consequences, especially in developing countries like Ghana. This study examines the determinants of profit in tomato marketing in the Ashanti Region of Ghana. Cross-sectional data collected from a random sample of 200 tomato marketers consisting of 100 wholesalers and 100 retailers were analyzed using descriptive statistics and the multiple linear regression technique of the ordinary least squares. The results show that wholesalers have a higher margin of 99.7 percent, while the retailers have a margin of 75.4 percent. Labour cost, purchase price, transportation cost and selling price run through all the estimated regressions as determinants of marketing profit. The effects of these variables on marketing profit could raise public concern since they have implications on prices received by tomato producers and those paid by final consumers and therefore there is the need for the government to devise policies aimed at stabilizing the local currency.The results also call for policy efforts to completely eliminate illiteracy among tomato traders in Ghana especially in the Ashanti Region. Policies that could enable the retailers to increase their scale of operations are also advocated. Future researchers may also estimate the exact point in the age variable at which retail profit declines and possible antecedents.

Market information and price volatility in petroleum derivatives spot and future markets

International Nuclear Information System (INIS)

Khalid Nainar, S.M.

1993-01-01

This paper examines the relationship between petroleum futures trading, market information and spot prices. It tests the hypothesis that there is increased spot market information with futures trading of various petroleum derivatives for weekly data during the period January 1970 to July 1985 at the new York Mercantile Exchange. Increased market information with futures trading is indicated by the insignificance of coefficients of past prices in spot price regressions in periods with futures trading. However, the estimates of the coefficient of variation indicate that price volatility tends to increase with futures trading. Thus, traders seem better informed with futures trading although the advantages of increased market information might potentially be undermined by increased price volatility as in the case of regular gasoline.

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

Energy Technology Data Exchange (ETDEWEB)

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.

Gasoline taxes or efficiency standards? A heterogeneous household demand analysis

International Nuclear Information System (INIS)

Liu, Weiwei

2015-01-01

Using detailed consumer expenditure survey data and a flexible semiparametric dynamic demand model, this paper estimates the price elasticity and fuel efficiency elasticity of gasoline demand at the household level. The goal is to assess the effectiveness of gasoline taxes and vehicle fuel efficiency standards on fuel consumption. The results reveal substantial interaction between vehicle fuel efficiency and the price elasticity of gasoline demand: the improvement of vehicle fuel efficiency leads to lower price elasticity and weakens consumers’ sensitivity to gasoline price changes. The offsetting effect also differs across households due to demographic heterogeneity. These findings imply that when gasoline taxes are in place, tightening efficiency standards will partially offset the strength of taxes on reducing fuel consumption. - Highlights: • Model household gasoline demand using a semiparametric approach. • Estimate heterogeneous price elasticity and fuel efficiency elasticity. • Assess the effectiveness of gasoline taxes and efficiency standards. • Efficiency standards offset the impact of gasoline taxes on fuel consumption. • The offsetting effect differs by household demographics

Impact of Germany's energy transition on the Nordic power market – A market-based multi-region energy system model

2016-01-01

The EU energy policy aims at creating a single European electricity market through market couplings and grid expansions. To analyse the implications of such power market couplings, we propose a market-based multi-region energy system model. The model simulates a multi-region power market (by applying market optimization and network theory), with detailed representation of each region as an energy system (by simulation of both heat and power sectors). We examine the impact of further integration of variable renewable energy (VRE) in Germany on the Nordic power market. The results indicate that the average electricity price slightly grows in the Nordic power market after Germany's Energy Transition (Energiewende). Hence, the economic surplus of Nordic consumers diminishes while Nordic producers improve their gain under new market conditions. Considering the gird congestion income, the overall system-level benefits (social welfare) will improve in the Nordic region after Germany's Energiewende. However, this gain is not equally distributed among different Nordic countries and across different stakeholders. Furthermore, the Energiewende slightly increases carbon emissions from power and district heating (DH) sectors, and reduces the flexibility in integration of VRE in some Nordic countries like Denmark. The direct interconnection of Norway and Germany through NordLink will contribute to the flexibility in wind integration in other Nordic countries, such as Denmark and Finland. - Highlights: • By an integrated hourly analysis, we model the energy systems of several networked countries and their common electricity market. • The proposed model can inform energy policy on implications of renewable energy integration in an international power market. • Among Nordic countries, Norway gains the highest economic benefits from Germany's energy transition. • Germany's energy transition constrains the flexibility of the Nordic countries in wind integration. • Nord

Regional energy system optimization - Potential for a regional heat market

Energy supply companies and industrial plants are likely to face new situations due to, for example, the introduction of new energy legislation, increased fuel prices and increased environmental awareness. These new prerequisites provide companies with new challenges but also new possibilities from which to benefit. Increased energy efficiency within companies and increased cooperation between different operators are two alternatives to meet the new conditions. A region characterized by a high density of energy-intensive processes is used in this study to find the economic potential of connecting three industrial plants and four energy companies, within three local district heating systems, to a regional heat market, in which different operators provide heat to a joint district heating grid. Also, different investment alternatives are studied. The results show that the economical potential for a heat market amounts to between 5 and 26 million EUR/year with payback times ranging from two to eleven years. However, the investment costs and the net benefit for the total system need to be allotted to the different operators, as they benefit economically to different extents from the introduction of a heat market. It is also shown that the emissions of CO 2 from the joint system would decrease compared to separate operation of the systems. However, the valuation of CO 2 emissions from electricity production is important as the difference of emitted CO 2 between the accounting methods exceeds 650 kton/year for some scenarios

Projected reformulated gasoline and AFV use in California

International Nuclear Information System (INIS)

Bemis, G.R.

1995-01-01

In the spring to summer of 1996, California will switch from conventional and oxygenated gasolines to reformulated gasoline. This gasoline will be a designer fuel, and generally not available from sources outside California, since California's fuel specifications then will be unique. Thus, it will be important for California refiners to be able to meet the California reformulated gasoline (Cal-RFG) demand. California refiners are investing over $4 billion to upgrade their facilities for Cal-RFG. This represents approximately 40% of the total cost of making Cal-RFG, and is expected to cost 5--15 cents/gallon more than conventional gasoline to produce. Starting in the year 2000, EPA will require use of a similar fuel in seven geographical areas outside of California. The discussion below focuses on the supply, demand and price projections for Cal-RFG

Laminar burning velocities at elevated pressures for gasoline and gasoline surrogates associated with RON

KAUST Repository

Mannaa, Ossama

2015-06-01

The development and validation of a new gasoline surrogate using laminar flame speed as a target parameter is presented. Laminar burning velocities were measured using a constant-volume spherical vessel with ignition at the center of the vessel. Tested fuels included iso-octane, n-heptane, toluene, various mixtures of primary reference fuels (PRFs) and toluene reference fuels (TRFs) and three gasoline fuels of 70, 85 and 95 RON (FACE J, C and F) at the initial temperature of 358K and pressures up to 0.6MPa in the equivalence ratio ranging from 0.8 to 1.6. Normalized laminar burning velocity data were mapped into a tri-component mixture space at different experimental conditions to allocate different gasoline surrogates for different gasoline fuels, having RON of 70, 85 and 95. The surrogates of TRF-70-4 (17.94% iso-C8H18 +42.06% n-C7H16 +40% C7H8), TRF-85-1 (77.4% iso-C8H18 +17.6% n-C7H16 +5% C7H8), and TRF-95-1 (88.47% iso-C8H18 +6.53% n-C7H16 +5% C7H8) of RON 70, 85 and 95, respectively, are shown to successfully emulate the burning rate characteristics of the gasoline fuels associated with these RONs under the various experimental conditions investigated. An empirical correlation was derived to obtain laminar burning velocities at pressures that are experimentally unattainable as high as 3.0MPa. Laminar burning velocities were comparable to the simulated values for lean and stoichiometric flames but they were relatively higher than the simulated values for rich flames. A flame instability assessment was conducted by determining Markstein length, critical Pecklet number, and critical Karlovitz number at the onset of flame instability.

Hydrogen cyanide (HCN) is considered a marker for biomass burning emissions and is a component of vehicle exhaust. Despite its potential health impacts, vehicular HCN emissions estimates and their contribution to regional budgets are highly uncertain. In the current study, Proton Transfer Reaction-Time of Flight-Mass Spectrometry (PTR-ToF-MS) was used to measure HCN emission factors from the exhaust of individual diesel, biodiesel and gasoline vehicles. Laboratory emissions data as a function of fuel type and driving mode were combined with ambient measurement data and model predictions. The results indicate that gasoline vehicles have the highest emissions of HCN (relative to diesel fuel) and that biodiesel fuel has the potential to significantly reduce HCN emissions even at realistic 5% blend levels. The data further demonstrate that gasoline direct injection (GDI) engines emit more HCN than their port fuel injection (PFI) counterparts, suggesting that the expected full transition of vehicle fleets to GDI will increase HCN emissions. Ambient measurements of HCN in a traffic dominated area of Toronto, Canada were strongly correlated to vehicle emission markers and consistent with regional air quality model predictions of ambient air HCN, indicating that vehicle emissions of HCN are the dominant source of exposure in urban areas. The results further indicate that additional work is required to quantify HCN emissions from the modern vehicle fleet, particularly in light of continuously changing engine, fuel and after-treatment technologies.

Eltony, M.N.

1993-01-01

This paper provides an estimate of household gasoline demand in Canada by applying a detailed model to pool time-series (1969-1988) and cross-sectional provincial data. The model recognises three major behavioural changes that households can make in response to gasoline price changes: drive fewer miles, purchase fewer cars, and buy more fuel-efficient vehicles. In the model, fuel economy is treated in considerable detail. The two components of the fuel economy of new cars sold-the technical fuel efficiency of various classes of cars and the distribution of new car sales according to their interior volume rather than their weight - are estimated as functions of economic variables. Car manufacturers are assumed to improve the technical fuel economy according to their expectation of consumer's response to future changes in gasoline prices and general economic conditions.

The effects of hydrous ethanol gasoline on combustion and emission characteristics of a port injection gasoline engine

Directory of Open Access Journals (Sweden)

Xiaochen Wang

2015-09-01

Full Text Available Comparative experiments were conducted on a port injection gasoline engine fueled with hydrous ethanol gasoline (E10W, ethanol gasoline (E10 and pure gasoline (E0. The effects of the engine loads and the additions of ethanol and water on combustion and emission characteristics were analyzed deeply. According to the experimental results, compared with E0, E10W showed higher peak in-cylinder pressure at high load. Increases in peak heat release rates were observed for E10W fuel at all the operating conditions. The usage of E10W increased NOX emissions at a wide load range. However, at low load conditions, E10W reduced HC, CO and CO2 emissions significantly. E10W also produced slightly less HC and CO emissions, while CO2 emissions were not significantly affected at higher operating points. Compared with E10, E10W showed higher peak in-cylinder pressures and peak heat release rates at the tested operating conditions. In addition, decreases in NOX emissions were observed for E10W from 5 Nm to 100 Nm, while HC, CO and CO2 emissions were slightly higher at low and medium load conditions. From the results, it can be concluded that E10W fuel can be regarded as a potential alternative fuel for gasoline engine applications.

As oil deposits are limited, it is very important to develop techniques for manufacturing petroleum alternatives as substitute energy sources to brighten the outlook for the future. The Research Association for Petroleum Alternatives Development (RAPAD) in Japan is engaged in the research and development of production techniques for light hydrocarbon oils such as gasoline, kerosene, and light oil from synthesis gas (CO, H/sub 2/) obtained from the raw materials of natural gas, coal, etc. Regarding the MTG process of synthesizing gasoline via methanol from synthesis gas and the STG process of directly synthesizing gasoline from synthesis gas, Cosmo Oil Co., Ltd. and Mitsubishi Heavy Industries, Ltd., members of RAPAD, have sought jointly to develop catalysts and processes. As a result of this co-operation, the authors have recently succeeded in developing a new catalyst with a long life span capable of providing a high yield and high selectivity. Additionally, the authors are currently on the verge of putting into effect a unique two-step STG process of synthesizing high octane gasoline via dimethyl ether, referred to as the AMSTG process.

Our results support the view that agglomeration economies...

The integration of major fuel source markets in China. Evidence from panel cointegration tests

International Nuclear Information System (INIS)

Ma, Hengyun; Oxley, Les

2010-01-01

The paper tests for energy price co-movement in China over the 'new regime' as part of a strategy to test for the existence of a national energy market. Panel cointegration test statistics suggest that not all energy commodities are spatially homogenous in prices and the processes of energy price cointegration are different over time and over groups of fuels. The statistics demonstrate China's gradual, spatially partial and idiosyncratic energy reform process. Coal and electricity price series have co-moved since 2003, while the national panel cointegration test statistics suggest that gasoline and diesel price series have co-moved since 1997. Regional panel tests also show that there are apparently differences in the emergence of energy price co-movement. This suggests that regional energy markets have emerged in China. One of the important lessons of the research is that an energy market has, to some extent, already emerged in China and, as a consequence, energy prices are much less distorted than previously. If correct, this fact is of major global significance both in terms of future environmental effects and future trade and investment negotiations as China is seen internationally as a 'market driven economy'.

Degradation of tetraethyllead during the degradation of leaded gasoline hydrocarbons in soil

International Nuclear Information System (INIS)

Mulroy, P.T.; Ou, L.T.

1998-01-01

For over 50 years, leaded gasoline was the only fuel for automobiles, and tetraethyllead (TEL) was the major octane number enhancer used in leaded gasoline. Ample information is available on the fate and remediation of gasoline hydrocarbons in contaminated subsoils and groundwater. However, little is known regarding the fate of TEL in leaded gasoline-contaminated subsoils and groundwater. In soil not contaminated with gasoline, TEL was rapidly degraded and completely disappeared in 14 d. In gasoline-contaminated soil, TEL degradation was slower; after 77 d, 4 to 17% of the applied TEL still remained in the contaminated soil. Disappearance of total petroleum hydrocarbons (TPH) was initially rapid but slowed appreciably after 7 to 14 d. As a result, after 77 d, 33 to 51% of the applied gasoline still remained in soil. The retardation of TEL degradation in leaded gasoline-contaminated soil is due to the presence of gasoline hydrocarbons. As long as gasoline hydrocarbons remain in soil, TEL may also remain in soil, most likely in the gasoline hydrocarbon phase

Generation adequacy and transmission interconnection in regional electricity markets

International Nuclear Information System (INIS)

Cepeda, Mauricio; Saguan, Marcelo; Finon, Dominique; Pignon, Virginie

2009-01-01

The power system capacity adequacy has public good features that cannot be entirely solved by electricity markets. Regulatory intervention is then necessary and established methods have been used to assess adequacy and help regulators to fix this market failure. In regional electricity markets, transmission interconnections play an important role in contributing to adequacy. However, the adequacy problem and related policy are typically considered at a national level. This paper presents a simple model to study how the interconnection capacity interacts with generation adequacy. First results indicate that increasing interconnection capacity between systems improves adequacy up to a certain level; further increases do not procure additional adequacy improvements. Furthermore, besides adequacy improvement, increasing transmission capacity under asymmetric adequacy criteria or national system characteristics could create several concerns about externalities. These results imply that regional coordination of national adequacy policies is essential to internalise adequacy of cross-border effects.

Performance of a hybrid hydrogen–gasoline engine under various operating conditions

International Nuclear Information System (INIS)

Ji, Changwei; Wang, Shuofeng; Zhang, Bo

2012-01-01

Highlights: ► We develop a combustion strategy for the hybrid hydrogen–gasoline engine (HHGE). ► The HHGE produced much lower HC and CO emissions at cold start. ► The H 2 -gasoline blends were effective for improving engine performance at idle and part loads. ► The HHGE could run smoothly at lean conditions. -- Abstract: This paper proposed a new combustion strategy for the spark-ignited (SI) engines. A gasoline engine was converted into a hybrid hydrogen–gasoline engine (HHGE) by adding a hydrogen injection system and a hybrid electronic control unit. Different from the conventional gasoline and hydrogen–enriched gasoline engines, the HHGE is fueled with the pure hydrogen at cold start to produce almost zero emissions, with the hydrogen–gasoline blends at idle and part loads to further improve thermal efficiency and reduce emissions, and with the pure gasoline to ensure the engine power output at high loads. Because the HHGE is fueled with the pure gasoline at high loads and speeds, experiments are only conducted at clod start, idle and part load conditions. Since lean combustion avails the further improvement of the engine performance, the HHGE was fueled with the lean mixtures in all tests. The experimental results showed that the hybrid hydrogen–gasoline engine was started successfully with the pure hydrogen, which produced 94.7% and 99.5% reductions in HC and CO emissions within 100 s from the onset of the cold start, compared with the original gasoline engine. At an excess air ratio of 1.37 and idle conditions, indicated thermal efficiency of the 3% hydrogen–blended gasoline engine was 46.3% higher than that of the original engine. Moreover, the engine cyclic variation was eased, combustion duration was shortened and HC, CO and NOx emissions were effectively reduced for the hybrid hydrogen–gasoline engines.

Gasoline tax best path to reduced emissions

International Nuclear Information System (INIS)

Brinner, R.E.

1991-01-01

Lowering gasoline consumption is the quickest way to increase energy security and reduce emissions. Three policy initiatives designed to meet such goals are current contenders in Washington, DC: higher gasoline taxes; higher CAFE (Corporate Average Fuel Economy) standards; and an auto registration fee scheme with gas-guzzler taxes and gas-sipper subsidies. Any of these options will give us a more fuel-efficient auto fleet. The author feels, however, the gasoline tax holds several advantages: it is fair, flexible, smart, and honest. But he notes that he is proposing a substantial increase in the federal gasoline tax. Real commitment would translate into an additional 50 cents a gallon at the pump. While the concept of increasing taxes at the federal level is unpopular with voters and, thus, with elected officials, there are attractive ways to recycle the $50 billion in annual revenues that higher gas taxes would produce

Combustion characteristics of a gasoline engine with independent intake port injection and direct injection systems for n-butanol and gasoline

International Nuclear Information System (INIS)

He, Bang-Quan; Chen, Xu; Lin, Chang-Lin; Zhao, Hua

2016-01-01

Highlights: • Different injection approaches for n-butanol and gasoline affect combustion events. • High n-butanol percentage in the total energy of fuels improves combustion stability. • N-butanol promotes ignition and shortens combustion duration. • Lean burn increases indicated mean effective pressure at fixed total energy of fuels. • Different fuel injection methods slightly affect indicated mean effective pressure. - Abstract: N-butanol, as a sustainable biofuel, is usually used as a blend with gasoline in spark ignition engines. In this study, the combustion characteristics were investigated on a four-cylinder spark ignition gasoline engine with independent port fuel injection and direct injection systems for n-butanol and gasoline in different operating conditions. The results show that in the case of port fuel injection of n-butanol with direct injection gasoline at a given total energy released in a cycle, indicated mean effective pressure is slightly affected by spark timing at stoichiometry while it changes much more with delayed spark timing in lean burn conditions and is much higher in lean burn conditions compared to stoichiometry at given spark timings. With the increase of n-butanol percentage in a fixed total energy released in a cycle at given spark timings, ignition timing advances, combustion duration shortens, indicated mean effective pressure and indicated thermal efficiency increase. For the cases of port fuel injection of n-butanol with direction injection gasoline and port fuel injection of gasoline with direction injection n-butanol at a fixed total energy released in a cycle, their indicated mean effective pressures are close. But their combustion processes are dependent on fuel injection approaches.

The history, genotoxicity, and carcinogenicity of carbon-based fuels and their emissions. Part 3: diesel and gasoline.

Science.gov (United States)

Claxton, Larry D

2015-01-01

Within this review the genotoxicity of diesel and gasoline fuels and emissions is placed in an historical context. New technologies have changed the composition of transportation methods considerably, reducing emissions of many of the components of health concern. The similarity of modern diesel and gasoline fuels and emissions to other carbonaceous fuels and emissions is striking. Recently an International Agency for Research on Cancer (IARC) Working Group concluded that there was sufficient evidence in humans for the carcinogenicity of diesel exhaust (Group 1). In addition, the Working Group found that diesel exhaust has "a positive association (limited evidence) with an increased risk of bladder cancer." Like most other carbonaceous fuel emissions, diesel and gasoline exhausts contain toxic levels of respirable particles (PM gasoline emissions has declined in certain regions over time because of changes in engine design, the development of better aftertreatment devices (e.g., catalysts), increased fuel economy, changes in the fuels and additives used, and greater regulation. Additional research and better exposure assessments are needed so that decision makers and the public can decide to what extent diesel and gasoline engines should be replaced.

Biofuels policy and the US market for motor fuels: Empirical analysis of ethanol splashing

Low ethanol prices relative to the price of gasoline blendstock, and tax credits, have resulted in discretionary blending at wholesale terminals of ethanol into fuel supplies above required levels-a practice known as ethanol splashing in industry parlance. No one knows precisely where or in what volume ethanol is being blended with gasoline and this has important implications for motor fuels markets: Because refiners cannot perfectly predict where ethanol will be blended with finished gasoline by wholesalers, they cannot know when to produce and where to ship a blendstock that when mixed with ethanol at 10% would create the most economically efficient finished motor gasoline that meets engine standards and has comparable evaporative emissions as conventional gasoline without ethanol blending. In contrast to previous empirical analyses of biofuels that have relied on highly aggregated data, our analysis is disaggregated to the level of individual wholesale fuel terminals or racks (of which there are about 350 in the US). We incorporate the price of ethanol as well as the blendstock price to model the wholesaler's decision of whether or not to blend additional ethanol into gasoline at any particular wholesale city-terminal. The empirical analysis illustrates how ethanol and gasoline prices affect ethanol usage, controlling for fuel specifications, blend attributes, and city-terminal-specific effects that, among other things, control for differential costs of delivering ethanol from bio-refinery to wholesale rack. - Research Highlights: > Low ethanol prices and tax credits have resulted in discretionary blending of ethanol into fuel supplies above required levels. > This has important implications for motor fuels markets and vehicular emissions. > Our analysis incorporates the price of ethanol as well as the blendstock price to model the wholesaler's decision of whether or not to blend additional ethanol into gasoline at any particular wholesale city

Optimization of the octane response of gasoline/ethanol blends

KAUST Repository

Badra, Jihad; AlRamadan, Abdullah S.; Sarathy, Mani

2017-01-01

The octane responses of gasoline/ethanol mixtures are not well understood because of the unidentified intermolecular interactions in such blends. In general, when ethanol is blended with gasoline, the Research Octane Number (RON) and the Motor Octane Number (MON) non-linearly increase or decrease, and the non-linearity is determined by the composition of the base gasoline and the amount of added ethanol. The complexity of commercial gasolines, comprising of hundreds of different components, makes it challenging to understand ethanol-gasoline synergistic/antagonistic blending effects. Understanding ethanol blending effects with simpler gasoline surrogates is critical to acquire knowledge about ethanol blending with complex multi-component gasoline fuels. In this study, the octane numbers (ON) of ethanol blends with five relevant gasoline surrogate molecules were measured. The molecules investigated in this study include: n-pentane, iso-pentane, 1,2,4-trimethylbenzene, cyclopentane and 1-hexene. These new measurements along with the available data of n-heptane, iso-octane, toluene, various primary reference fuels (PRF) and toluene primary reference fuels (TPRF) with ethanol are used to develop a blending rule for the octane response (RON and MON) of multi-component blends with ethanol. In addition, new ON data are collected for six Fuels for Advanced Combustion Engine (FACE) with ethanol. The relatively simple volume based model successfully predicts the octane numbers (ON) of the various ethanol/PRF and ethanol/TPRF blends with the majority of predictions being within the ASTM D2699 (RON) and D2700 (MON) reproducibility limits. The model is also successfully validated against the ON of the FACE gasolines blended with ethanol with the majority of predictions being within the reproducibility limits. Finally, insights into the possible causes of the synergistic and antagonistic effects of different molecules with ethanol are provided.

Renato Baumann

2013-03-01

Full Text Available In some Latin American countries the exporting activity starts at a regional level, with producers only later venturing into more competitive markets. The implicit risk is that a country might never progress from the regional stage to a more global market. This article compares the experiences of Brazil, China and India. It is shown that Brazil relied on the regional market far more intensely than these Asian countries. There were clear gains accruing to China and India for having exploited more sophisticated markets from the very beginning of their export drive.

Energy market integration and regional institutions in east Asia

Aalto, Pami

2014-01-01

This article assesses the case made for energy market integration in East Asia by comparing the role of institutions in South East Asia and North East Asia. The types and functions of institutions and their overall structure are examined in light of global energy market trends. In South East Asia, the shift attempted by ASEAN towards more competitive markets is hampered by the remaining statist variants of the trade institution and bilateral energy diplomacy, which, as regards transaction cost functions, are sub-optimal. As for institutions with order-creating functions, the unresolved status of sovereignty within ASEAN hampers regulatory harmonisation; the great power management institution has since ASEAN's establishment reduced conflicts without providing decisive leadership conducive to integration. North East Asia's dependence on global energy markets overshadows the regional integration potential of the diverse liberalisation efforts and interconnection projects. Bilateral energy diplomacies, new trilateral institutions combined with ‘Track Two’ institutions and remaining great power competition co-exist. In both regions the institutional structure allows for step-wise, technical infrastructure integration. The environmental stewardship institution co-exists with statist energy security and development objectives while it supports cooperation on green energy. The overall structure of informal institutions constrains deeper energy market integration in several ways. - Highlights: • The structures of institutions explain East Asian energy market integration. • Transaction costs are increased by statist trade institutions and bilateralism. • Order-creating institutions are sub-optimal for energy market integration. • Multi-level great power management offers limited leadership for integration. • The environmental stewardship institution supports cooperation on green energy

The development of regional markets of eggs production in Russia

Full Text Available The current state of regional markets development and the production of eggs and egg products for a long period — from 1990 to 2009 — is reviewed in this paper. The main research method is the method of statistical groupings. The variable amount of egg production was chosen as the grouping characteristic, since this figure fits well into research goals and has the property of the prevalence in the aggregate / total. To analyze the trends of the Russian regional markets involved into egg production, official statistics on consumer prices was used as well as producer prices, the volume of egg production per capita based on food import and export products. This allowed to group regions for comparison with average values of indicators carried out by different criteria, and to draw conclusions about trends in the development of regional markets. The most relevant factors influencing the development of egg production, among which the factor of vertical integration of production was especially noticed: building own plants and feed mills, joining the land in order to ensure the needs for higher quality raw materials and other activities were identified.

Impact of unleaded gasoline in reducing emissions in Saudi Arabia

2001-01-15

Saudi Arabia is dealing progressively with tighter restrictions on refined product qualities. Efforts are ongoing within the country concerning the phase-out of lead in motor gasoline and the reduction of sulfur in diesel as well. The removal of lead is the main characteristic of environmental friendly gasoline. The detrimental health effects of using leaded gasoline are many, and lead exposure can cause kidney failure, brain dysfunction, behavioral problems, and neurological impairment. Saudi Arabia is moving towards using unleaded gasoline, and efforts are being put forward by research organizations to produce lead-free gasoline in the Kingdom. A high severity fluid catalytic cracking process is being developed for converting vacuum gas oil into high-octane gasoline components. This process requires high temperature and pressure and low contact time as compared to the conventional FCC process. (author)

Owens, E.H.; Reiter, G.A.; Challenger, G.

2000-01-01

On June 10, 1999, a pipe ruptured on the Olympic Pipe Line causing the release, explosion and fire of up to one million litres of gasoline in Bellingham, Washington. It affected approximately 5 km of the Whatcom Creek ecosystem. Following the incident, several concurrent activities in the source area and downstream occurred. This paper discussed the remediation of the affected stream bed sections. During the period July 6 - August 16, an interagency project was implemented. It involved mechanical, manual, and hydraulic in-situ treatment techniques to remove the gasoline from the stream bed and the banks. In addition, a series of controlled, hydraulic flushes were conducted. The sluice or control gates at the head of the Whatcom Creek were opened each night, and bigger flushes took place before and after the treatments. Simultaneously, water and sediment were sampled and analysed. The data obtained provided information on the state of the initial stream water and stream sediment and on the effects that the remediation had had. The residual gasoline was successfully removed from the sediments and river banks in six weeks. No downstream movement of the released gasoline towards Bellingham was detected. 3 refs., 2 tabs., 11 figs

COMPETITIVE FEATURES IN THE MARKET STRUCTURE OF HOUSING PROPERTY WITH REGARD TO REGIONAL DEFINITIONS

Full Text Available The subject of research. Given the steady demand for residential real estate, the low solvency of the population, and unbalanced development of individual segments of the regional housing market, competition issues and the mechanism of its operation, today is very relevant. Real estate is one of the components of the national economy because it carries more than half of total world wealth and its stable functioning is one of the most complex processes of market transformations occurring in the country. Active functioning property markets are a prerequisite for the sustainable development of cities and regions of the country. This development is the basis for the effective management of regional and implemented in the system of national governance and local governance. In modern terms, Ukraine is at the stage of the market system, one of which is real estate market. From the way, the subject of study is a competitive relationship, and especially their formation in the regional real estate market. Methodology. In order to carry out a thorough study, there was elaborated numerous scientific literature authored by leading scientists of Ukraine, Europe, and the former Soviet Union camp to define the concepts of “competition”, “regional market”, “real estate”, “residential property”. According to the research of current problems and competitive features in the structure of the real estate market on the basis of regional specificity, a logical systematization of these concepts is made. Results of the research allowed us to “carry” a clear parallel between the correlation of factors and competitive impact on the regional real estate market of the potential buyers, the developer and manufacturer of products directly to real estate as an object relationship. Practical implications. The article is to study the specific competitive position in the regional real estate market in Ukraine and also features of exposure to it by consumers

A unified world oil market: Regions in physical, economic, geographic, and political space

International Nuclear Information System (INIS)

Kaufmann, Robert K.; Banerjee, Shayan

2014-01-01

Although there is a general consensus that the market is unified, here we quantify the factors that create regions by analyzing the price relation between 33 crude oils. ADF statistics indicate that 447 of the 528 crude oil pairings cointegrate; 81 do not. The presence/absence of cointegration is analyzed using a logit model. The likelihood that the prices for two crude oils cointegrate depends on their physical characteristics (density and sulfur content), economic factors (country risk for the nation of origin), their geographic location (distance between supply ports), and political factors (OPEC membership). Over the sample period, the technology to refine heavy crude oils penetrates the market, and this reduces the price difference between heavy and light crude oils. The effect of country risk implies that crude oils from high risk nations are not perfect substitutes for crude oils of similar quality from low risk nations. Finally, crude oils from widely separated suppliers are more likely to cointegrate than crude oils from near-by nations, which suggests consumers diversify supply across transportation chokepoints. For this sample, these sources of regionalization add $0.20 per barrel to the $2.86 average price difference between crude oils in the same market. Together, these factors have important implications for the efficacy of policy aimed at reducing dependence on unreliable suppliers and the spill-over effects of holding inventories. - Highlights: • The world oil market is not completely unified. • Regions are defined by differences in API gravity and sulfur content. • Country risk regionalizes the world oil market. • Shipping chokepoints regionalize the world oil market. • Regionalization adds $0.20 to $2.86 price difference between oils in same market

Economic and environmental benefits of higher-octane gasoline.

We quantify the economic and environmental benefits of designing U.S. light-duty vehicles (LDVs) to attain higher fuel economy by utilizing higher octane (98 RON) gasoline. We use engine simulations, a review of experimental data, and drive cycle simulations to estimate the reduction in fuel consumption associated with using higher-RON gasoline in individual vehicles. Lifecycle CO2 emissions and economic impacts for the U.S. LDV fleet are estimated based on a linear-programming refinery model, a historically calibrated fleet model, and a well-to-wheels emissions analysis. We find that greater use of high-RON gasoline in appropriately tuned vehicles could reduce annual gasoline consumption in the U.S. by 3.0-4.4%. Accounting for the increase in refinery emissions from production of additional high-RON gasoline, net CO2 emissions are reduced by 19-35 Mt/y in 2040 (2.5-4.7% of total direct LDV CO2 emissions). For the strategies studied, the annual direct economic benefit is estimated to be $0.4-6.4 billion in 2040, and the annual net societal benefit including the social cost of carbon is estimated to be $1.7-8.8 billion in 2040. Adoption of a RON standard in the U.S. in place of the current antiknock index (AKI) may enable refineries to produce larger quantities of high-RON gasoline.

Flow of gasoline-in-water microemulsion through water-saturated soil columns

Much consideration has been given to the use of surfactants to clean up nonaqueous phase liquids (NAPLs) from contaminated soil and ground water. Although this emulsification technique has shown significant potential for application in environmental remediation practices, a major obstacle leading to low washing efficiency is the potential formation of macroemulsion with unfavorable flow characteristics in porous media. This study investigated influences of the flow of leaded-gasoline-in-water (LG/W) microemulsion upon the transport of gasoline and lead (Pb) species in water-saturated soil columns. Two experiments were performed: (1) the immiscible displacement of leaded gasoline and (2) the miscible displacement of LG/W microemulsion through soil columns, followed by sequentially flushing with NaCl solution and a water/surfactant/cosurfactant (W/S/CoS) mixture. Comparison of breakthrough curves (BTC) for gasoline between the two experiments shows that about 90% of gasoline and total Pb were removed from the soil columns by NaCl solution in the LG/W microemulsion experiment as compared to 40% removal of gasoline and 10% removal of total Pb at the same process in the leaded gasoline experiment. Results indicate that gasoline and Pb species moved much more effectively through soil during miscible flow of LG/W microemulsion than during immiscible flow of leaded gasoline. In contrast to the adverse effects of macroemulsion on the transport of NAPLs, microemulsion was found to enhance the transport of gasoline through water-saturated soil. Mass balance analysis shows that the W/S/CoS mixture had a high capacity for removing residual gasoline and Pb species from contaminated soil. Comparison of water-pressure differences across the soil columns for the two experiments indicates that pore clogging by gasoline droplets was greatly minimized in the LG/W microemulsion experiment

Research document no. 24. The integration of european electric markets: from the national markets juxtaposition to the establishment of a regional market

International Nuclear Information System (INIS)

Finon, D.

2000-11-01

After the transcription of the electricity directive in national legislations, the European electricity market appears to be a vast set of juxtaposed markets which are weakly connected at the level of their wholesale contracts compartment. Referring to the technological peculiarities of electricity as a commodity, the paper identifies the direct conditions of regional integration of the electricity markets, those which would favour cross-border trade and allow to be near the normal functioning of a regional commodity market. The infrastructure network dependence and the need of a stringent technical coordination necessitate to unify the operation of the different systems and the rules of access, or at the least to come near this unification by strong coordination. A second major condition, which is not fully debated, is the increasing connexion of short-term markets, via daily physical trade and emergence of a European financial market, which could trade various standardised contracts referring to a single hourly spot price, or to prices in various delivery points. To reach such an integration, two paths are possible: either concentration into one single organised power exchange as the Nordic pool, or rules harmonization of the various power exchanges which would be a minimal requirement to allow arbitrations between them.

The policy challenges of tradable credits: A critical review of eight markets

International Nuclear Information System (INIS)

Sovacool, Benjamin K.

2011-01-01

This article offers a critical review of eight tradable permit markets: water permits at Fox River, Wisconsin; the U.S. leaded gasoline phase-out; sulfur dioxide credits under the U.S. Clean Air Act Amendments of 1990; the Regional Clean Air Incentives Market (RECLAIM) for controlling ozone and acid rain in Southern California; renewable energy credit trading at the regional level in the United States; individual transferrable quotas for fisheries at the national level in New Zealand; carbon credits traded under the European Union-Emissions Trading Scheme; and carbon offsets permitted under the Clean Development Mechanism of the Kyoto Protocol. By 'critical' the article does not fully weigh the costs and benefits of each tradable credit scheme and instead identifies key challenges and problems. By 'review' the author relied exclusively on secondary data from an interdisciplinary review of the academic literature. Rather than performing as economic theory suggests, the article shows that in many cases credit markets are prone to compromises in program design, transaction costs, price volatility, leakage, and environmental degradation. The article concludes by discussing the implications of these problems for those seeking to design more equitable and effective public policies addressing environmental degradation and climate change. - Research Highlights: →This study reviews eight tradable credit markets. →It finds that markets are prone to common problems. →It concludes that tradable permit markets are political instruments as much as they are economic ones.

Ford envisions additional fuel economy improvement in the medium and long term by further advancing EcoBoost technology. The approach for the project was to engineer a comprehensive suite of gasoline engine systems technologies to achieve the project objectives, and to progressively demonstrate the objectives via concept analysis / computer modeling, single-cylinder and multi-cylinder engine testing on engine dynamometer, and vehicle level testing on chassis rolls.

Degradation of tetraethyllead in leaded gasoline contaminated and uncontaminated soils

International Nuclear Information System (INIS)

Ou, L.; Jing, W.; Thomas, J.; Mulroy, P.

1995-01-01

For over 50 years, since its introduction in 1923 by General Motors, tetraethyllead (TEL) was the major antiknock agent used in leaded gasoline. Since the middle of 1970, use of leaded gasoline in automobiles was gradually phased out. The main objective of this study is to determine the degradation rates and metabolites of TEL in gasoline contaminated and uncontaminated soils. TEL in uncontaminated soils disappeared rapidly. Ionic triethyllead (TREL) was the major organolead metabolite in these soils, with ionic diethyllead (DEL) being the minor product. Nonsterile soils, but not autoclaved soils, had limited capacity to mineralize 14 C-TEL to 14 CO 2 , H 2 0, and Pb 2+ . Unlike TEL in uncontaminated soils, petroleum hydrocarbons protected TEL in leaded gasoline contaminated soils from being degraded. Both disappearance and mineralization rates of TEL in leaded gasoline contaminated soils decreased with the increase in gasoline concentration. It appears that TEL in leaded gasoline contaminated soils is relatively stable until the level of petroleum hydrocarbons falls below a critical value. TEL is then rapidly degraded. Hydrocarbon degrading microorganisms may be involved, to some extent, in the degradation of TEL

Closing the gasoline system

International Nuclear Information System (INIS)

Hutcheson, R.C.

1992-01-01

In this paper, a representative of the Oil Companies' European Organization for Environmental and Health Protection (CONCAWE), argues the advantages of closing the gasoline system. Because this decouples the product from the environment, health risks and environmental damage are reduced. It is also more effective than changing the composition of gasoline because it offers better cost effectiveness, energy efficiency and the minimization of carbon dioxide release into the environment. However it will take time and political will to change until all European vehicles are fitted with three way catalysts and carbon canisters: control systems to monitor such systems will also need to be set up. However CONCAWE still recommends its adoption. (UK)

Assessing Rates of Global Warming Emissions from Port- Fuel Injection and Gasoline Direct Injection Engines in Light-Duty Passenger Vehicles

Science.gov (United States)

Short, D.; , D., Vi; Durbin, T.; Karavalakis, G.; Asa-Awuku, A. A.

2013-12-01

Passenger vehicles are known emitters of climate warming pollutants. CO2 from automobile emissions are an anthropogenic greenhouse gas (GHG) and a large contributor to global warming. Worldwide, CO2 emissions from passenger vehicles are responsible for 11% of the total CO2 emissions inventory. Black Carbon (BC), another common vehicular emission, may be the second largest contributor to global warming (after CO2). Currently, 52% of BC emissions in the U.S are from the transportation sector, with ~10% originating from passenger vehicles. The share of pollutants from passenger gasoline vehicles is becoming larger due to the reduction of BC from diesel vehicles. Currently, the majority of gasoline passenger vehicles in the United States have port- fuel injection (PFI) engines. Gasoline direct injection (GDI) engines have increased fuel economy compared to the PFI engine. GDI vehicles are predicted to dominate the U.S. passenger vehicle market in the coming years. The method of gasoline injection into the combustion chamber is the primary difference between these two technologies, which can significantly impact primary emissions from light-duty vehicles (LDV). Our study will measure LDV climate warming emissions and assess the impact on climate due to the change in U.S vehicle technologies. Vehicles were tested on a light- duty chassis dynamometer for emissions of CO2, methane (CH4), and BC. These emissions were measured on F3ederal and California transient test cycles and at steady-state speeds. Vehicles used a gasoline blend of 10% by volume ethanol (E10). E10 fuel is now found in 95% of gasoline stations in the U.S. Data is presented from one GDI and one PFI vehicle. The 2012 Kia Optima utilizes GDI technology and has a large market share of the total GDI vehicles produced in the U.S. In addition, The 2012 Toyota Camry, equipped with a PFI engine, was the most popular vehicle model sold in the U.S. in 2012. Methane emissions were ~50% lower for the GDI technology

Speed of adjustment and market structure

International Nuclear Information System (INIS)

Lanza, A.

1991-01-01

This paper studies the relationship between changes in costs and prices in the gasoline market in the Federal Republic of Germany for the period 1980-90. We shall use an econometric model, and distinguish two stages in the transmission of cost changes to prices. The first is the adjustment of gasoline prices ex-refinery to changes in the price of crude oil, and the second is the adjustment of gasoline price (net of taxes) at the pump to ex-refinery prices. The study of price adjustments to cost changes involves the analysis of two inter-related but different phenomena. The first is the speed of adjustment, defined here as the mean of the length of the time periods required for the transmission of the full effect of an exogenous shock from the independent to the dependent variable of the econometric model used in the analysis. The second relates to possible asymmetries in the response of prices to increases and decreases in costs. Both phenomena are closely related to the structure of the market. The common assumption is that the first is negatively correlated to the degree of competition, and that the second is an indication of the prevailing market structure. The main findings of this paper are as follows: (a) at the refinery level there is only weak evidence of asymmetrical reaction; the average lag in case of crude price increases or decreases is about three months; (b) at the consumers' level, the speed of adjustment was lower when the ex-refinery price was declining than when it was rising; the adjustment lag was about 6.07 months when ex-refinery prices were declining and 5.37 months when they were rising.

Chi, Guangqing; McClure, Timothy E; Brown, David B

2012-09-01

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

2014-11-01

This paper is part of a special series of publications regarding gasoline toxicology testing and gasoline risk management; this article covers regulations, standards, and industry practices concerning gasoline risk management. Gasoline is one of the highest volume liquid fuel products produced globally. In the U.S., gasoline production in 2013 was the highest on record (API, 2013). Regulations such as those pursuant to the Clean Air Act (CAA) (Clean Air Act, 2012: § 7401, et seq.) and many others provide the U.S. federal government with extensive authority to regulate gasoline composition, manufacture, storage, transportation and distribution practices, worker and consumer exposure, product labeling, and emissions from engines and other sources designed to operate on this fuel. The entire gasoline lifecycle-from manufacture, through distribution, to end-use-is subject to detailed, complex, and overlapping regulatory schemes intended to protect human health, welfare, and the environment. In addition to these legal requirements, industry has implemented a broad array of voluntary standards and best management practices to ensure that risks from gasoline manufacturing, distribution, and use are minimized.

A fuel metering system has been adapted and permits operation on all blends of alcohols and gasoline ranging from pure gasoline to pure ethanol and methanol. It is a closed loop electronic feedback controlled fuel injection system (EFI) with exhaust oxygen sensor. The system is used by Toyota Motor Company in their Supra and Cressida models in conjunction with a 3-way catalytic exhaust system. These models meet California exhaust and evaporative emission standards. An unmodified model has been tested on alcohol gasoline blends from pure gasoline to 50% ethanol-50% gasoline and 30% methanol-70% gasoline and found to meet all exhaust and evaporative emissions standards. A Cressida with modified EFI system is currently being tested. It is capable of operating on pure gasoline, pure methanol or ethanol and all intermediate blends. The testing to date shows that the vehicle meets all exhaust emissions standards while operating over the blend range from pure gasoline to pure ethanol while maintaining driveability and energy based fuel economy. The paper will present the total test evidence for all gasoline-alcohol blends. This will include exhaust and evaporative emissions, fuel economy and driveability as determined in accordance with United States Federal Test Procedures. Additionally, the paper will report experiences accumulated from road operation of the vehicle over a six-month period.

In OKTA Crude Oil Refinery - Skopje the production of butane as a pure component is based on a liquid phase and it is used for both TNG (propane-butane gas) and motor gasoline production with a quality that satisfy the standard. By using the butane as a gasoline component the quality of the MB-98 and BMB has been improved. The butane itself ensures octane improvement of the pool, by what the content of the lead additives or the octane of the main component - reformat decreases. Also, the butane addition decreases the density of the final products by what the financial effects have been improved. It is also interesting to explain the usage of butane for gasoline production concerning the new proposed standard. The paper presents the practical results, through tables and diagrams, of the butane usage as a component for gasoline production, as well as the butane influence to the quality of the produced gasoline.

Gasoline Biodesulfurization DE-FC07-97ID13570 FINAL REPORT

Energy Technology Data Exchange (ETDEWEB)

Pienkos, Philip T.

2002-01-15

Nine strains were identified to grow with gasoline as sole sulfur source. Two different genes were cloned from Gordonia terrae KGB1 and tested for the ability to support gasoline BDS. The first of these, fmoA, was cloned by screening a KGB1 gene library for the ability to convert indole to indigo (a sulfur-regulated capability in KGB1). The fmoA gene was overexpressed in a gasoline tolerant strain of Pseudomonas putida PpG1 and the recombinant strain was shown to convert thiophene to a dimer of thiophene sulfoxide at rates nearly two orders of magnitude higher than KGB1 could catalyze the reaction. Despite this high activity the recombinant PpG1 was unable to demonstrate any activity against gasoline either in shake flask or in bench-scale gasoline BDS bioreactor. A second gene (toeA) was cloned from KGB1 and shown to support growth of Rhodococcus erythropolis JB55 on gasoline. The toeA gene was also identified in another gasoline strain T. wratislaviensis EMT4, and was identified as a homolog of dszA from R. erythropolis IGTS8. Expression of this gene in JB55 supported conversion of DBTO2 (the natural substrate for DszA) to HPBS, but activity against gasoline was low and BDS results were inconsistent. It appeared that activity was directed against C2- and C3-thiophenes. Efforts to increase gene expression by plasmid manipulation, by addition of flavin reductase genes, or by expression in PpG1 were unsuccessful. The DszC protein (DBT monooxygenase) from IGTS8 has very little activity against the sulfur compounds in gasoline, but a mutant enzyme with a substitution of phenylalanine for valine at position 261 was shown to have an altered substrate range. This alteration resulted in increased activity against gasoline, with activity towards mainly C3- and C4-thiophenes and benzothiophene. A mutant library of dszB was constructed by RACHITT (W. C.

Martínez, María Antonia; Ballesteros, Salomé; Alcaraz, Rafael

2012-02-10

The investigation of uncertain fatalities requires accurate determination of the cause of death, with assessment of all factors that may have contributed to it. Gasoline is a complex and highly variable mixture of aliphatic and aromatic hydrocarbons that can lead to cardiac arrhythmias due to sensitization of the myocardium to catecholamines or acts as a simple asphyxiant if the vapors displace sufficient oxygen from the breathing atmosphere. This work describes a sudden occupational fatality involving gasoline. The importance of this petroleum distillate detection and its quantitative toxicological significance is discussed using a validated analytical method. A 51 year-old Caucasian healthy man without significant medical history was supervising the repairs of the telephone lines in a manhole near to a gas station. He died suddenly after inhaling gasoline vapors from an accidental leak. Extensive blistering and peeling of skin were observed on the skin of the face, neck, anterior chest, upper and lower extremities, and back. The internal examination showed a strong odor of gasoline, specially detected in the respiratory tract. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography with flame ionization detector and confirmation was performed using gas chromatography-mass spectrometry. Disposition of gasoline in different tissues was as follows: heart blood, 35.7 mg/L; urine, not detected; vitreous humor, 1.9 mg/L; liver, 194.7 mg/kg; lung, 147.6 mg/kg; and gastric content, 116,6 mg/L (2.7 mg total). Based upon the toxicological data along with the autopsy findings, the cause of death was determined to be gasoline poisoning and the manner of death was accidental. We would like to alert on the importance of testing for gasoline, and in general for volatile hydrocarbons, in work-related sudden deaths involving inhalation of hydrocarbon vapors and/or exhaust fumes.

Senior governments asked to return half of gasoline taxes collected in GTA

International Nuclear Information System (INIS)

2001-01-01

The Greater Toronto Services Board addressed a submission to the Standing Committee on Finance of the House of Commons in Ottawa and to the Legislature of the Province of Ontario, requesting the federal and provincial governments to earmark half the money they collect in gasoline taxes from motorists in the Greater Toronto Area (GTA) for local transportation spending, and by so doing help to end traffic gridlock in the GTA. In its submission the GTSB claims that as a result of 'pervasive traffic congestion' the GTA is quickly losing competitive ground to US cities that are enjoying substantial financial support from their federal government. The GTSB calculates that motorists throughout the GTA paid more than $1.7 billion to the federal and provincial governments in gasoline taxes; if half that amount, $863 million, were returned to the GTA and earmarked for transportation improvements, that would cover the GTA's shortfall on capital spending on roads and public transit, currently estimated at $800 million. The GTSB points out that the GTA generates about 18 per cent of the country's and 45 per cent of the province's gross domestic product; it would be false economy to neglect the needs of a region that is such a major producer of the country's and the province's wealth. The submission also points out the recommendation of a federal panel recently reviewing the Canada Transportation Act, that federal gasoline tax revenues should be reinvested in roads and public transit rather than going into general revenue. The submission emphasizes as the one inescapable reality of the global economy that financial and human resources flow to places where they see advantage, and avoid places where they see problems. City-regions with efficient roads and public transit systems and a healthy environment are bound to be in a better position to attract global businesses and their employees to their region than city-regions which are constantly mired in gridlock

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

Energy Technology Data Exchange (ETDEWEB)

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.

The purpose of this study is to investigate possible improvements in ICEVs by implementing fuzzy logic-based parallel hard-type power hybrid systems. Two types of conventional ICEVs (gasoline and diesel) and two types of HEVs (gasoline-electric, diesel electric) were generated using vehicle and powertrain simulation tools and a Matlab-Simulink application programming interface. For gasoline and gasoline-electric HEV vehicles, the prediction accuracy for four types of LDV models was validated by conducting comparative analysis with the chassis dynamometer and OBD test data. The predicted results show strong correlation with the test data. The operating points of internal combustion engines and electric motors are well controlled in the high efficiency region and battery SOC was well controlled within ±1.6%. However, for diesel vehicles, we generated virtual diesel-electric HEV vehicle because there is no available vehicles with similar engine and vehicle specifications with ICE vehicle. Using a fuzzy logic-based parallel hybrid system in conventional ICEVs demonstrated that HEVs showed superior performance in terms of fuel consumption and CO 2 emission in most driving modes.

2006-01-01

The Guangxi Zhuang autonomous region has plentiful cassava resources, which is an ideal feedstock for fuel ethanol production. The Guangxi government intends to promote cassava fuel ethanol as a substitute for gasoline. The purpose of this study was to quantify the energy efficiency and potentials of a cassava fuel ethanol project in the Guangxi region based on a 100 thousand ton fuel ethanol demonstration plant at Qinzhou of Guangxi. The net energy value (NEV) and net renewable energy value (NREV) are presented to assess the energy and renewable energy efficiency of the cassava fuel ethanol system during its life cycle. The cassava fuel ethanol system was divided into five subsystems including the cassava plantation/treatment, ethanol conversion, denaturing, refueling and transportation. All the energy and energy related materials inputs to each subsystem were estimated at the primary energy level. The total energy inputs were allocated between the fuel ethanol and its coproducts with market value and replacement value methods. Available lands for a cassava plantation were investigated and estimated. The results showed that the cassava fuel ethanol system was energy and renewable energy efficient as indicated by positive NEV and NREV values that were 7.475 MJ/L and 7.881 MJ/L, respectively. Cassava fuel ethanol production helps to convert the non-liquid fuel into fuel ethanol that can be used for transportation. Through fuel ethanol production, one Joule of petroleum fuel, plus other forms of energy inputs such as coal, can produce 9.8 J of fuel ethanol. Cassava fuel ethanol can substitute for gasoline and reduce oil imports. With the cassava output in 2003, it can substitute for 166.107 million liters of gasoline. With the cassava output potential, it can substitute for 618.162 million liters of gasoline. Cassava fuel ethanol is more energy efficient than gasoline, diesel fuel and corn fuel ethanol but less efficient than biodiesel

The crisis of gasoline consumption in the Iran's transportation sector

International Nuclear Information System (INIS)

Houri Jafari, H.; Baratimalayeri, A.

2008-01-01

Fossil fuels have the greatest share in supplying the world's energy demands. Regarding the limited natural resources, fuel consumption management and energy planning in the end-user sectors are two great matters of importance. Among the fossil fuels, gasoline is the principal fuel for light-duty vehicles. In Iran, fuel consumption, especially that of gasoline, has increased sharply with the growth rate of 10.2% for the year 2006 in comparison with that in 2005, turning into a big crisis in the recent years. On the other hand, enormous subsidies for importing 40% of domestic demands, which have reached more than 10 billion US$, are too much to be supplied. In this study, we have assessed the gasoline consumption, production, import and prices; reviewed main causes of the tremendous growth rate of consumption, current conservation policies and their advantages or disadvantages (SWOT analysis); proposed short- to long-term solutions and strategies for efficient gasoline consumption management; and finally, current strategies and proposed solutions are analyzed and evaluated. A foregone conclusion strongly suggests that not only the low price of motor gasoline but also mass production of vehicles with the conventional technology, likewise, affects motor gasoline demand. A second conclusion is that gasoline crisis in Iran has no straight solution, and that fundamental strategies and policies are needed to solve the problem. (author)

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.

Zhu, He; Wilson, Fernando A; Stimpson, Jim P; Hilsenrath, Peter E

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.

Electrokinetic enhanced bioventing of gasoline in clayey soil: A case history

International Nuclear Information System (INIS)

Loo, W.W.; Wang, I.S.; Fan, J.

1994-01-01

This paper presents a case history on the bioventing of gasoline in soil with electrokinetic enhancement. The gasoline in soil was related to a 10,000-gallon underground storage tank spill, San Diego, California. The gasoline soil plume covers an area of about 2,400 square feet and to a depth of about 30 feet. The upper 15 feet of the soil plume consists of highly conductive marine clay. The lower 15 feet of the soil plume consists of dense cemented conglomerate sandstone. The gasoline concentration in the soil plume range from 100 to 2,200 mg/Kg(ppm) and the target cleanup level is below 100 ppm. Total gasoline in soil plume is estimated at about 1,000 pounds of gasoline in about 3,500 tons of soil. The soil remediation effort was completed after about 90 days of treatment. The concentration of gasoline in soil after treatment was way below the proposed cleanup level of less than 100 mg/Kg(ppm). The cost of treatment is about $50 per ton for this advanced soil treatment process which provides a cost effective solution to this soil plume with minimum disruption to business operation at the facility

Park, Su Han; Kim, Hyung Jun; Suh, Hyun Kyu; Lee, Chang Sik

2009-01-01

The focus of this study was to investigate the spray characteristics and atomization performance of gasoline fuel (G100), bioethanol fuel (E100), and bioethanol blended gasoline fuel (E85) in a direct injection gasoline injector in a gasoline engine. The overall spray and atomization characteristics such as an axial spray tip penetration, spray width, and overall SMD were measured experimentally and predicted by using KIVA-3V code. The development process and the appearance timing of the vortices in the test fuels were very similar. In addition, the numerical results accurately described the experimentally observed spray development pattern and shape, the beginning position of the vortex, and the spray breakup on the spray surface. Moreover, the increased injection pressure induced the occurrence of a clear circular shape in the downstream spray and a uniform mixture between the injected spray droplets and ambient air. The axial spray tip penetrations of the test fuels were similar, while the spray width and spray cone angle of E100 were slightly larger than the other fuels. In terms of atomization performance, the E100 fuel among the tested fuels had the largest droplet size because E100 has a high kinematic viscosity and surface tension.

Geography of Existing and Potential Alternative Fuel Markets in the United States

Energy Technology Data Exchange (ETDEWEB)

Johnson, C.; Hettinger, D.

2014-11-01

When deploying alternative fuels, it is paramount to match the right fuel with the right location, in accordance with local market conditions. We used six market indicators to evaluate the existing and potential regional market health for each of the five most commonly deployed alternative fuels: electricity (used by plug-in electric vehicles), biodiesel (blends of B20 and higher), E85 ethanol, compressed natural gas (CNG), and propane. Each market indicator was mapped, combined, and evaluated by industry experts. This process revealed the weight the market indicators should be given, with the proximity of fueling stations being the most important indicator, followed by alternative fuel vehicle density, gasoline prices, state incentives, nearby resources, and finally, environmental benefit. Though markets vary among states, no state received 'weak' potential for all five fuels, indicating that all states have an opportunity to use at least one alternative fuel. California, Illinois, Indiana, Pennsylvania, and Washington appear to have the best potential markets for alternative fuels in general, with each sporting strong markets for four of the fuels. Wyoming showed the least potential, with weak markets for all alternative fuels except for CNG, for which it has a patchy market. Of all the fuels, CNG is promising in the greatest number of states--largely because freight traffic provides potential demand for many far-reaching corridor markets and because the sources of CNG are so widespread geographically.

2012-03-15

Leakage of gasoline and diesel from underground tanks has led to a severe environmental problem in many countries. Tracing the production origin of gasoline and diesel is required to enable the development of dispute resolution and appropriate remediation strategies for the oil-contaminated sites. We investigated the bulk and compound-specific isotopic compositions of gasoline produced by four oil companies in South Korea: S-Oil, SK, GS and Hyundai. The relative abundance of several compounds in gasoline was determined by the peak height of the major ion (m/z 44). The δ(13)C(Bulk) and δD(Bulk) values of gasoline produced by S-Oil were significantly different from those of SK, GS and Hyundai. In particular, the compound-specific isotopic value (δ(13)C(CSIA)) of methyl tert-butyl ether (MTBE) in S-Oil gasoline was significantly lower than that of gasoline produced by other oil companies. The abundance of several compounds in gasoline, such as n-pentane, MTBE, n-hexane, toluene, ethylbenzene and o-xylene, differed widely among gasoline from different oil companies. This study shows that gasoline can be forensically discriminated according to the oil company responsible for its manufacture using stable isotope analysis combined with multivariate statistical analysis.

Experimental study on emissions and performance of an internal combustion engine fueled with gasoline and gasoline/n-butanol blends

International Nuclear Information System (INIS)

Elfasakhany, Ashraf

2014-01-01

Highlights: • Using of 3 and 7 vol.% n-butanol blends in SI engine is studied for the first time. • Engine performance and emissions depend on both engine speed and blend rates. • CO and UHC for blended fuels are maximum at 3000–3100 r/min. • The higher the rate of n-butanol, the lower the emissions and performance. • This study strongly supports using low blend rates of n-butanol (<10 vol.%) in ICE. - Abstract: In this paper, exhaust emissions and engine performance have been experimentally studied for neat gasoline and gasoline/n-butanol blends in a wide range of working speeds (2600–3400 r/min) without any tuning or modification on the gasoline engine systems. The experiment has the ability of evaluating performance and emission characteristics, such as break power, torque, in-cylinder pressure, volumetric efficiency, exhaust gas temperature and concentrations of CO 2 , CO and UHC. Results of the engine test indicated that using n-butanol–gasoline blended fuels slightly decrease the output torque, power, volumetric efficiency, exhaust gas temperature and in-cylinder pressure of the engine as a result of the leaning effect caused by the n-butanol addition; CO, CO 2 and UHC emissions decrease dramatically for blended fuels compared to neat gasoline because of the improved combustion since n-butanol has extra oxygen, which allows partial reduction of the CO and UHC through formation of CO 2 . It was also noted that the exhaust emissions depend on the engine speed rather than the n-butanol contents

Performance and emissions of gasoline blended with terpineol as an octane booster

KAUST Repository

Vallinayagam, R.

2016-11-10

This study investigates the effect of using terpineol as an octane booster for gasoline fuel. Unlike ethanol, terpineol is a high energy density biofuel that is unlikely to result in increased volumetric fuel consumption when used in engines. In this study, terpineol is added to non-oxygenated FACE F gasoline (Research Octane Number = 94.5) in volumetric proportions of 10%, 20% and 30% and tested in a single cylinder spark ignited engine. The performance of terpineol blended fuels are compared against a standard oxygenated EURO V (ethanol blended) gasoline. It was determined that the addition of terpineol to FACE F gasoline enhanced the octane number of the blend, resulting in improved brake thermal efficiency and total fuel consumption. For FACE F + 30% terpineol, break thermal efficiency was improved by 12.1% over FACE F gasoline at full load for maximum brake torque operating point, and similar performance as EURO V gasoline was achieved. Due to its high energy density, total fuel consumption was reduced by 6.2% and 9.7% with 30% terpineol in the blend when compared to FACE F gasoline at low and full load conditions, respectively. Gaseous emissions such as total hydrocarbon and carbon monoxide emission were reduced by 36.8% and 22.7% for FACE F + 30% terpineol compared to FACE F gasoline at full load condition. On the other hand, nitrogen oxide and soot emissions are increased for terpineol blended FACE F gasoline when compared to FACE F and EURO V gasoline. © 2016 Elsevier Ltd

Environmental impacts of energy use can impose large costs on society. We quantify and monetize the life-cycle climate-change and health effects of greenhouse gas (GHG) and fine particulate matter (PM2.5) emissions from gasoline, corn ethanol, and cellulosic ethanol. For each billion ethanol-equivalent gallons of fuel produced and combusted in the US, the combined climate-change and health costs are $469 million for gasoline, $472–952 million for corn ethanol depending on biorefinery heat source (natural gas, corn stover, or coal) and technology, but only $123–208 million for cellulosic ethanol depending on feedstock (prairie biomass, Miscanthus, corn stover, or switchgrass). Moreover, a geographically explicit life-cycle analysis that tracks PM2.5 emissions and exposure relative to U.S. population shows regional shifts in health costs dependent on fuel production systems. Because cellulosic ethanol can offer health benefits from PM2.5 reduction that are of comparable importance to its climate-change benefits from GHG reduction, a shift from gasoline to cellulosic ethanol has greater advantages than previously recognized. These advantages are critically dependent on the source of land used to produce biomass for biofuels, on the magnitude of any indirect land use that may result, and on other as yet unmeasured environmental impacts of biofuels.

Petrol pump workers are occupationally exposed to gasoline and its fumes consisting of several mutagenic chemicals. To evaluate the genotoxic effects of exposure to gasoline fumes on petrol pump workers. The study groups included 70 petrol pump workers (exposed group) and 70 healthy age-matched individuals with no known exposure (comparison group). Buccal micronucleus cytome assay (BMCyt) was performed to check the genotoxicity caused due to inhalation of gasoline fumes. The frequencies of micronucleated cells, nuclear bud, condensed chromatin cells, karyorrhectic cells, pyknotic cells, and karyolytic cells were significantly higher in the exposed workers compared to the comparison group. Exposure to gasoline fumes is associated with increased frequency of cell abnormalities. This may lead to various health consequences including cancer in those occupationally exposed to gasoline fumes.

To explore new and multifunctional additives for methanol-gasoline, tartaric ester were synthesized and screened as phase stabilizer and saturation vapor pressure depressor for methanol-gasoline. The effect of the esters structure on the efficiency was discussed. The results show that the stabilities of the blends depend on the length of the glycolic esters alkoxy group. In addition, the tartaric esters also can depress the saturation vapor pressure of methanol-gasoline effectively in M15. Effect of the structure on the efficiency was also discussed. (author)

Gasoline Biodesulfurization DE-FC07-97ID13570 FINAL REPORT; FINAL

Nine strains were identified to grow with gasoline as sole sulfur source. Two different genes were cloned from Gordonia terrae KGB1 and tested for the ability to support gasoline BDS. The first of these, fmoA, was cloned by screening a KGB1 gene library for the ability to convert indole to indigo (a sulfur-regulated capability in KGB1). The fmoA gene was overexpressed in a gasoline tolerant strain of Pseudomonas putida PpG1 and the recombinant strain was shown to convert thiophene to a dimer of thiophene sulfoxide at rates nearly two orders of magnitude higher than KGB1 could catalyze the reaction. Despite this high activity the recombinant PpG1 was unable to demonstrate any activity against gasoline either in shake flask or in bench-scale gasoline BDS bioreactor. A second gene (toeA) was cloned from KGB1 and shown to support growth of Rhodococcus erythropolis JB55 on gasoline. The toeA gene was also identified in another gasoline strain T. wratislaviensis EMT4, and was identified as a homolog of dszA from R. erythropolis IGTS8. Expression of this gene in JB55 supported conversion of DBTO2 (the natural substrate for DszA) to HPBS, but activity against gasoline was low and BDS results were inconsistent. It appeared that activity was directed against C2- and C3-thiophenes. Efforts to increase gene expression by plasmid manipulation, by addition of flavin reductase genes, or by expression in PpG1 were unsuccessful. The DszC protein (DBT monooxygenase) from IGTS8 has very little activity against the sulfur compounds in gasoline, but a mutant enzyme with a substitution of phenylalanine for valine at position 261 was shown to have an altered substrate range. This alteration resulted in increased activity against gasoline, with activity towards mainly C3- and C4-thiophenes and benzothiophene. A mutant library of dszB was constructed by RACHITT (W. C.

Martin, R.P.; Zaman, Q.U.

1999-01-01

Medical research has established a clear link between elevated blood lead levels nd adverse health effects in humans including the retardation of neurological development, hypertension, and cardiovascular ailments. Due to this, a large number of countries now restrict the sale of leaded gasoline. In contrast, only highly leaded gasoline is readily available in Pakistan, resulting in serious health concerns in certain areas. This paper presents the findings of a study to evaluate consumers' perceived benefits and actual costs of switching to unleaded gasoline in Pakistan. Policy implications are noted. The study indicates a concentration of adverse health effects in the major urban centers. Of special interest is the loss of approximately 2,5000 IQ points annually in Karachi and Lahore as a result of gasoline linked lead exposure. Consumers' willingness to pay for the removal of lead from gasoline, as estimated using a contingent valuation technique, is shown to be positively related to both educational attainment and income. Once consumers are informed of the adverse health effects associated with lead exposure, their willingness to pay for a switch to unleaded gasoline for exceeds the costs incurred. This suggests that significant gains in social welfare may be obtained by phasing out lead from gasoline in Pakistan. The benefits are most pronounced in urban areas, while in rural villages and small cities the costs are likely to out weight the benefits. A flexible program to restrict the sale of leaded gasoline in urban areas is thus recommended. (author)

Preterm birth (PTB) is a growing public health problem potentially associated with ambient air pollution. Gasoline service stations can emit atmospheric pollutants, including volatile organic compounds potentially implicated in PTB. The objective of this study was to evaluate the relationship between residential proximity to gasoline service stations and PTB. Singleton live births on the Island of Montreal from 1994 to 2006 were obtained (n=267,478). Gasoline service station locations, presence of heavy-traffic roads, and neighborhood socioeconomic status (SES) were determined using a geographic information system. Multivariable logistic regression was used to analyze the association between PTB and residential proximity to gasoline service stations (50, 100, 150, 200, 250, and 500 m), accounting for maternal covariates, neighborhood SES, and heavy-traffic roads. For all distance categories beyond 50 m, presence of service stations was associated with a greater odds of PTB. Associations were robust to adjustment for maternal covariates for distance categories of 150 and 200 m but were nullified when adjusting for neighborhood SES. In analyses accounting for the number of service stations, the likelihood of PTB within 250 m was statistically significant in unadjusted models. Associations were, however, nullified in models accounting for maternal covariates or neighborhood SES. Our results suggest that there is no clear association between residential proximity to gasoline service stations in Montreal and PTB. Given the correlation between proximity of gasoline service stations and SES, it is difficult to delineate the role of these factors in PTB.

The identification of an arsonist remains one of the most difficult challenges a fire investigation has to face. Seeking and detection of traces of gasoline could provide a valuable information to link a suspect with an arson scene where gasoline was used to set-up the fire. In this perspective, a first study was undertaken to evaluate a simple, fast and efficient method for collecting gasoline from hands, and to assess its persistence over time. Four collection means were tested: PVC, PE and Latex gloves, as well as humidified filter paper. A statistical assessment of the results indicates that Latex and PVC gloves worn for about 20 min, as well as paper filter rubbed on hands, allow an efficient collection of gasoline applied to hands. Due to ease of manipulation and to a reduced amount of volatile compounds detected from the matrix, PVC gloves were selected for the second set of experiments. The evaluation of the persistence of gasoline on hands was then carried out using two initial quantities (500 and 1000 microl). Collection was made with PVC gloves after 0, 30 min, 1, 2 and 4h, on different volunteers. The results show a common tendency of massive evaporation of gasoline during the first 30 min: a continued but non-linear decrease was observed along different time intervals. The results of this preliminary study are in agreement with other previous researches conducted on the detection of flammable liquid residues on clothes, shoes and skin.

Gasoline-related injuries and fatalities in the United States, 1995-2014.

Science.gov (United States)

Drago, Dorothy A

2018-02-12

This descriptive study examines twenty years of gasoline-related fatalities and emergency department treated injuries in the United States, based on data from the US Consumer Product Safety Commission. Thermal burns consistently accounted for the majority (56%) of gasoline-related injuries and for most (82%) gasoline-related deaths, and were commonly (57-71%) associated with the use of gasoline as an accelerant. Poisoning accounted for 13% of injuries and 17% of deaths. The primary poisoning injury pattern was ingestion; the primary fatality pattern was inhalation, with about half of those associated with deliberate abuse. The estimated number of ingestions decreased from 60 to 23% of poisoning-related injuries, while injuries associated with inhalation abuse increased from 6 to 23%. Chemical burns and dermatitis were less represented in the injury data and were primarily associated with gasoline spills or splashes. Gasoline cans reportedly ignited or exploded in about 5% of thermal burn injuries and fatalities. While mandatory requirements for child resistant closures on gasoline cans (a primary intervention) have potentially impacted poisonings, the use of flame mitigation devices to address thermal injuries, if successful, would be a secondary intervention, and could address only a small percentage (about 5%) of injuries and deaths.

Zinc-aluminates for an in situ sulfur reduction in cracked gasoline

Quintana-Solorzano, R.; Valente, J.S.; Hernandez-Beltran, F.J.; Castillo-Araiza, C.O. [Instituto Mexicano del Petroleo, Eje Central Lazaro Cardenas Norte 152 C.P., 07730 Mexico, D.F. (Mexico)

Using additives remains as an attractive alternative for an in situ sulfur reduction in cracked gasoline since it is a practical, flexible and economical option. Zinc-aluminates prepared by the sol-gel method are used as additives for reducing sulfur in gasoline from the cracking of a high-sulfur feed in a fixed-bed bench reactor. Products distribution and feed conversion are not dramatically altered after incorporating the additive to the base catalyst with some effect on gasoline and its octane number and coke. A decrease in the gasoline sulfur content of up to 35 wt% including benzothiophene, and up to 50% excluding benzothiophene, is observed when blending the zinc-aluminates to the base catalyst, which is caused by lowering the C{sub 1} to C{sub 4} alkyl-thiophenes content. The zinc content of the zinc-aluminates has a positive effect on the gasoline sulfur reduction. It is suggested that together with the direct cracking of adsorbed thiophenic species on the additive, a further gasoline sulfur decrease is possible through cracking of saturated thiophenic species formed by hydrogenation of adsorbed thiophenic species with hydrogen produced in situ in the additive. The obtained results also demonstrate that solids with higher Lewis acidity are not unfailingly the most effective for gasoline sulfur reduction. (author)

Nonlinearity and intraday efficiency tests on energy futures markets

2010-01-01

Using high frequency data, this paper first time comprehensively examines the intraday efficiency of four major energy (crude oil, heating oil, gasoline, natural gas) futures markets. In contrast to earlier studies which focus on in-sample evidence and assume linearity, the paper employs various nonlinear models and several model evaluation criteria to examine market efficiency in an out-of-sample forecasting context. Overall, there is evidence for intraday market inefficiency of two of the four energy future markets (heating oil and natural gas), which exists particularly during the bull market condition but not during the bear market condition. The evidence is also robust against the data-snooping bias and the model overfitting problem, and its economic significance can be very substantial. (author)

Lifecycle optimized ethanol-gasoline blends for turbocharged engines

KAUST Repository

Zhang, Bo

2016-08-16

This study presents a lifecycle (well-to-wheel) analysis to determine the CO2 emissions associated with ethanol blended gasoline in optimized turbocharged engines. This study provides a more accurate assessment on the best-achievable CO2 emission of ethanol blended gasoline mixtures in future engines. The optimal fuel blend (lowest CO2 emitting fuel) is identified. A range of gasoline fuels is studied, containing different ethanol volume percentages (E0–E40), research octane numbers (RON, 92–105), and octane sensitivities (8.5–15.5). Sugarcane-based and cellulosic ethanol-blended gasolines are shown to be effective in reducing lifecycle CO2 emission, while corn-based ethanol is not as effective. A refinery simulation of production emission was utilized, and combined with vehicle fuel consumption modeling to determine the lifecycle CO2 emissions associated with ethanol-blended gasoline in turbocharged engines. The critical parameters studied, and related to blended fuel lifecycle CO2 emissions, are ethanol content, research octane number, and octane sensitivity. The lowest-emitting blended fuel had an ethanol content of 32 vol%, RON of 105, and octane sensitivity of 15.5; resulting in a CO2 reduction of 7.1%, compared to the reference gasoline fuel and engine technology. The advantage of ethanol addition is greatest on a per unit basis at low concentrations. Finally, this study shows that engine-downsizing technology can yield an additional CO2 reduction of up to 25.5% in a two-stage downsized turbocharged engine burning the optimum sugarcane-based fuel blend. The social cost savings in the USA, from the CO2 reduction, is estimated to be as much as $187 billion/year. © 2016 Elsevier Ltd

Capital Markets, Infrastructure Investment and Growth in the Asia Pacific Region

Directory of Open Access Journals (Sweden)

Michael Regan

2017-02-01

Full Text Available This paper examines the relationship between infrastructure investment activity, capital market development, the role of public institutions and economic development in the Asia Pacific. It adopts a review approach drawing on empirical evidence over recent decades. Infrastructure is shown to be an important asset class playing a central role in a nation’s output, growth, productivity and microeconomic performance. Infrastructure investment also requires investment and predictions of a widening gap in the future supply of infrastructure in the Asia Pacific will require new forms of capital from both traditional and new sources including wider use of private participation, institutional investment, asset recycling and revenue bonds. Capital market development is also necessary to raise long-term local currency finance and evidence suggests that progress with regional capital market integration is slow and a continuing reform agenda is required. The dividend for regional countries is the prospect of higher levels of economic growth with infrastructure investment, capital market development, and foreign direct investment shown to have a strong and positive association with growth. A crucial link in this association identified in the review is the part played by national and regional institutions in improving the efficiency with which infrastructure is managed and providing promising ground for further research where the importance of these links can be researched in greater depth.

Utilization of Renewable Oxygenates as Gasoline Blending Components

Energy Technology Data Exchange (ETDEWEB)

Yanowitz, J.; Christensen, E.; McCormick, R. L.

2011-08-01

This report reviews the use of higher alcohols and several cellulose-derived oxygenates as blend components in gasoline. Material compatibility issues are expected to be less severe for neat higher alcohols than for fuel-grade ethanol. Very little data exist on how blending higher alcohols or other oxygenates with gasoline affects ASTM Standard D4814 properties. Under the Clean Air Act, fuels used in the United States must be 'substantially similar' to fuels used in certification of cars for emission compliance. Waivers for the addition of higher alcohols at concentrations up to 3.7 wt% oxygen have been granted. Limited emission testing on pre-Tier 1 vehicles and research engines suggests that higher alcohols will reduce emissions of CO and organics, while NOx emissions will stay the same or increase. Most oxygenates can be used as octane improvers for standard gasoline stocks. The properties of 2-methyltetrahydrofuran, dimethylfuran, 2-methylfuran, methyl pentanoate and ethyl pentanoate suggest that they may function well as low-concentration blends with gasoline in standard vehicles and in higher concentrations in flex fuel vehicles.

2006-01-01

The paper presents the result of an ongoing research to evaluate performance and wear of small, single cylinder, naturally aspirated, agricultural spark ignition engines using biomass-derived ethanol and gasoline blends. The reference gasoline fuel was selected to be representative of gasoline typically available in Thailand. Long-term engine tests of 10% and 20% ethanol / gasoline blends as well as the reference fuel were performed at a constant speed of 2300 rpm under part load condition up to 200 operation hours for each fuel type. Engine brake power, specific fuel consumption, carbon deposits and surface wear were measured and compared between neat gasoline and ethanol/ gasoline blends. It was found that blended fuels appeared to affect the engine performance in a similar way and compared well with the base gasoline fuel. From the results obtained, it was found that engine brake power and specific fuel consumption changed slightly with running time and were not found to have any significant change between different fuel blends. There were carbon deposits buildup on the spark plug, the intake port and exhaust valve stem for all fuels used. Surface wear was not significantly different in the test engines between neat gasoline or ethanol/gasoline blend fuelling

Process for conversion of lignin to reformulated hydrocarbon gasoline

Science.gov (United States)

Shabtai, Joseph S.; Zmierczak, Wlodzimierz W.; Chornet, Esteban

1999-09-28

A process for converting lignin into high-quality reformulated hydrocarbon gasoline compositions in high yields is disclosed. The process is a two-stage, catalytic reaction process that produces a reformulated hydrocarbon gasoline product with a controlled amount of aromatics. In the first stage, a lignin material is subjected to a base-catalyzed depolymerization reaction in the presence of a supercritical alcohol as a reaction medium, to thereby produce a depolymerized lignin product. In the second stage, the depolymerized lignin product is subjected to a sequential two-step hydroprocessing reaction to produce a reformulated hydrocarbon gasoline product. In the first hydroprocessing step, the depolymerized lignin is contacted with a hydrodeoxygenation catalyst to produce a hydrodeoxygenated intermediate product. In the second hydroprocessing step, the hydrodeoxygenated intermediate product is contacted with a hydrocracking/ring hydrogenation catalyst to produce the reformulated hydrocarbon gasoline product which includes various desirable naphthenic and paraffinic compounds.

This paper explores the issue of 'fuel tourism' in Switzerland. For the period 1985-1997, a panel data model for the border regions of Switzerland, (Italy, France, and Germany) is estimated. The results show a significant impact of the gasoline price differential on demand, suggesting that a decrease of 10% in the Swiss gasoline price leads to an increase in demand in the border areas of nearly 17.5%. It is shown that fuel tourism accounted for about 9% of overall gasoline sales in the three regions during the period 1985-1997 and that the recently proposed Swiss CO 2 -tax might, given current conditions, eliminate net fuel tourism.

Gasoline content regulations are designed to curb pollution and improve health, but their impact on health has not been quantified. By exploiting both the timing of regulation and spatial variation in children's exposure to highways, I estimate the effect of gasoline content regulation on pollution and child health. The introduction of cleaner-burning gasoline in California in 1996 reduced asthma admissions by 8% in high exposure areas. Reductions are greatest for areas downwind from highways and heavy traffic areas. Stringent gasoline content regulations can improve child health, and may diminish existing health disparities.

Terpineol as a novel octane booster for extending the knock limit of gasoline

KAUST Repository

Vallinayagam, R.

2016-09-16

Improving the octane number of gasoline offers the potential of improved engine combustion, as it permits spark timing advancement without engine knock. This study proposes the use of terpineol as an octane booster for gasoline in a spark ignited (SI) engine. Terpineol is a bio-derived oxygenated fuel obtained from pine tree resin, and has the advantage of higher calorific value than ethanol. The ignition delay time (IDT) of terpineol was first investigated in an ignition quality tester (IQT). The IQT results demonstrated a long ignition delay of 24.7 ms for terpineol and an estimated research octane number (RON) of 104, which was higher than commercial European (Euro V) gasoline. The octane boosting potential of terpineol was further investigated by blending it with a non-oxygenated gasoline (FACE F), which has a RON (94) lower than Euro V gasoline (RON = 97). The operation of a gasoline direct injection (GDI) SI engine fueled with terpineol-blended FACE F gasoline enabled spark timing advancement and improved engine combustion. The knock intensity of FACE F + 30% terpineol was lower than FACE F gasoline at both maximum brake torque (MBT) and knock limited spark advance (KLSA) operating points. Increasing proportions of terpineol in the blend caused peak heat release rate, in-cylinder pressure, CA50, and combustion duration to be closer to those of Euro V gasoline. Furthermore, FACE F + 30% terpineol displayed improved combustion characteristics when compared to Euro V gasoline. © 2016

Summary. Different health risks including haematotoxicity and weight loss have been reported for gasoline. Supplementation with antioxidants such as vitamins A, C, and E has been shown to ameliorate the toxicity effects of gasoline vapours exposure. Honey contains vitamins, and polyphenols that possess good antioxidant properties. The potential role of honey in preventing gasoline-induced haematotoxicity and weight loss was assessed in male rats. The rats were exposed to gasoline (11.13±1.1cm...

Full Text Available In this study, the originally carburetted gasoline engine was converted to gas-phase liquefied petroleum gas (LPG injection engine by using an after market LPG conversion kit's components except the electronic control unit (ECU. Instead of after market LPG injection ECU, the ECU which was designed considering the effects of  electromagnetic interference (EMI, was used for controlling injection. The designed ECU was tested in terms of EMI while the engine was being run and it was detected that the EMI noises could be suppressed as possible by taken measures. Designed ECU was used in performance tests at different engine conditions and the results obtained with LPG injection were compared with the results obtained with LPG carburetion. According to the performance test results, LPG injection ECU designed in this study could help to achieve low exhaust emissions and high engine performance.

Petroleum derived gasoline is the most used transportation fuel for light-duty vehicles. In order to better understand gasoline combustion, this study investigated the ignition propensity of two alkane-rich FACE (Fuels for Advanced Combustion Engines) gasoline test fuels and their corresponding PRF (primary reference fuel) blend in fundamental combustion experiments. Shock tube ignition delay times were measured in two separate facilities at pressures of 10, 20, and 40 bar, temperatures from 715 to 1500 K, and two equivalence ratios. Rapid compression machine ignition delay times were measured for fuel/air mixtures at pressures of 20 and 40 bar, temperatures from 632 to 745 K, and two equivalence ratios. Detailed hydrocarbon analysis was also performed on the FACE gasoline fuels, and the results were used to formulate multi-component gasoline surrogate mixtures. Detailed chemical kinetic modeling results are presented herein to provide insights into the relevance of utilizing PRF and multi-component surrogate mixtures to reproduce the ignition behavior of the alkane-rich FACE gasoline fuels. The two FACE gasoline fuels and their corresponding PRF mixture displayed similar ignition behavior at intermediate and high temperatures, but differences were observed at low temperatures. These trends were mimicked by corresponding surrogate mixture models, except for the amount of heat release in the first stage of a two-stage ignition events, when observed. © 2014 The Combustion Institute.

The response of primary suppliers to Benzene in Gasoline Regulations was reviewed, and a summary of the effects of those regulations on the composition of gasoline in Canada in 2002 was offered. These regulations, effective July 1, 1999, were designed to provide a new approach to control fuel composition. It allowed suppliers, as a basis for compliance, the option to elect to use a yearly pool average. The benzene emission number (BEN) of gasoline was regulated, and a limit imposed on a per-litre limit for benzene at point of sale. The results indicated that reported benzene levels were significantly reduced, while aromatic levels remained practically unchanged from 1994. Since 1998, rural ambient benzene concentrations decreased by more than 32 per cent, while in urban areas, they decreased by 47 per cent over the same period. The regulated requirements for benzene concentration were met by primary suppliers in Canada in 2002 (with one exception), as were BEN levels. A number of instances of non-compliance with laboratory procedures were discovered during independent audits required for those suppliers who elected to be on on a yearly pool average. Corrective action designed to address these issues was implemented. 41 tabs., 24 figs.
