China Adopts Policies to Reduce Growing Oil Use

Unprecedented motorization in China has led to significant increases in oil demand and oil imports. In response to growing oil imports, the Chinese government is adopting a broad range of policies, including improvements in the fuel economy of new vehicles and the promotion of alternative-fuel vehicles. »

When residents of São Paulo chose gasoline over ethanol to fuel their vehicles, levels of ozone actually decreased, according to a Northwestern study.

Switch From Ethanol to Gasoline Causes Ozone Levels to Drop 20%

A Northwestern University study by an economist and a chemist reports that when fuel prices drove residents of São Paulo, Brazil, to mostly switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20 percent. At the same time, nitric oxide and carbon monoxide concentrations tended to go up. »

Scientists Make Gasoline-Like Fuel From Plant Waste

Gasoline-like fuels can be produced from cellulosic materials such as farm and forestry waste using a new process invented by chemists at the University of California, Davis. The process could open up new markets for plant-based fuels, beyond existing diesel substitutes. »

U.S. Light-Duty Vehicles Use 11% Less Fuel Since 2004

In a follow-up to two reports (1, 2) released earlier this year, Michael Sivak of the University of Michigan Transportation Research Institute (UMTRI) examined recent trends in fuel consumption by cars, pickup trucks, SUVs and vans in the U.S. fleet from 1984 to 2011. According to his findings, there is an 11% decline in fuel consumption by American drivers of light-duty vehicles. »

Study Challenges the Claim that Ethanol Makes Gas Cheaper

Does ethanol make gas cheaper? According to the “2013 Ethanol Industry Outlook” report by the Renewable Fuels Association, ethanol currently represents nearly 10 percent of the motor fuel supply in the U.S and the ethanol industry saves the average household more than $1200 in gasoline bills. Yet, a paper forthcoming in The Energy Journal, co-authored by an an MIT economist Christopher Knittel, states that the price of gasoline is not substantially affected by the volume of its ethanol content. »

First Gasoline Produced From Biomass With ‘Bioliq’ Process

First Gasoline Produced From Biomass With ‘Bioliq’ Process

For the first time, synthetic gasoline is produced by Karlsruhe Institute of Technology (KIT). The synthesis stage of the “bioliq” pilot plant successfully started operation. Now, all stages of the bioliq process, i.e. flash pyrolysis, high-pressure entrained-flow gasification, and synthesis, have been realized. The project will now be completed by testing the entire process chain and optimizing it for the large industrial scale. »

New Fluid Flow Research Will Help Oil Separation

In a paper appearing this month in Physical Review E, Sunny Jung, assistant professor of engineering science and mechanics at Virginia Tech, and five colleagues reported on the dynamics of squeezing fluids using a simple experiment of clapping with wet hands. The findings of this fluid flow research can help better understand the finer points of the oil separation process, making it more efficient. »

Novel Sponge-Like Material Could Improve Petroleum Refining

A newly synthesized crystalline compound might provide a dramatically improved method for separating the highest-octane components of gasoline by selectively adsorbing low-octane isomers. The research team, which included scientists from NIST and several other universities, has published its findings in the journal Science. »

EIA Explains Recent Rise in Gasoline Prices

Gasoline prices are going up—since the start of this year an average price for a gallon of regular gas have risen by 45 cents, reaching $3.75 per gallon on February 18. U.S. Energy Information Administration explains that the reason for this is in part the higher crude oil prices. The most of the price growth is, however, due to increased differential between the price of crude oil and petroleum products extracted from it (so-called crack spread). »

US Households Spend Record-High on Gasoline While Becoming More Efficient

EIA have calculated that an average american household spends almost 4% of its income on gasoline. While consumption figures are going down, prices go up: that accounts for the highest percentage of income spent on gasoline since 2008. Another notable trend is the increasing energy efficiency. »
