Researchers at the University of California, Davis have developed a process for the production of branched C 7 –C 10 hydrocarbons in the gasoline volatility range from biomass-derived levulinic acid with good yield, operating under relatively mild conditions, with short reaction times. barrels of oil (117.6 gallons US). gallons US).
A team at UC Davis has optimized the levulinic ester self-condensation reaction and the efficient conversion of its products—which are highly branched cyclopentadienes—into a mixture of substituted cyclopentanes with high octane ratings and excellent density and flow properties. Zheng Li, Andrew L.
Researchers at Stony Brook University, with colleagues from The City College of New Tyork, Alloy Surfaces and Innoveering, explored the catalytic partial oxidation (CPOX) reforming of three potential transportation-relevant fuels—gasoline, diesel, and natural gas—for use in low-temperature combustion (LTC) engines.
As a result, there is a critical need to create new pathways for biofuel conversion that reduces carbon waste, prevents the loss of CO 2 emissions, and in turn, maximizes the amount of renewable fuel a conversion process yields. University of California, Davis. The awardees are: LanzaTech, Inc. University of Delaware.
Production of bio-based jet and diesel is expected to begin in 2013 and production of bio-based gasoline, part of the C 3 product platform, will follow in 2015. The grant allows ZeaChem to use our existing integrated demonstration facility to develop advanced biofuels beyond cellulosic ethanol, including bio-based jet, diesel and gasoline.
Daniel Sperling, director of the Institute of Transportation Studies at the University of California, Davis, member of the California Air Resources Board, and one of the co-creators of the California LCFS. Set a target of reducing the carbon intensity of gasoline and diesel by 10 to 15 percent by 2030.
NO conversion versus ramp-up and ramp-down temperatures for MnCe-7:1 (?), The new material is active at temperatures as low as 120 °C with conversion maxima of ~45% higher than that achieved with Pt. Diesel engines are attractive because of their higher fuel efficiency than gasoline engines. SmMn 2 O 5 (?), and Pt (?).
While chemically converting natural gas to liquid fuels (GTL) is a proven technology that increases volumetric energy density, the current conversion approach through Fischer-Tropsch (FT-GTL) is challenged by both high capital costs and low conversion efficiencies. process intensification approaches for biological methane conversion.
Louis, MO), NAABB will develop a systems approach for sustainable commercialization of algal biofuel (such as renewable gasoline, diesel, and jet fuel) and bioproducts. University of California, Davis; UOP LLC; Virent Energy Systems; and Washington State University. Led by the Donald Danforth Plant Science Center (St.
They concluded Scenedesmus performed better in this process with impressive demonstrated total fuel yields of 97 gallons gasoline equivalents (GGE) per ton of biomass. per gallon gasoline equivalent (GGE) to $9.91/GGE Knoshaug, Ryan Davis, Lieve M.L. GGE from $10.86/GGE—a Tao Dong, Eric P. 2015.12.021.
Ford’s turbocharged, gasoline direct injection EcoBoost engines are targeted to play a significant near-term role in Ford’s efforts to reduce fuel consumption by enabling downsizing. The cold-start period constitutes the majority of engine emissions due to zero or low conversion efficiency of the aftertreatment system. Source: Ford.
The biogas is used for renewable heat and electricity to power the conversion process of the lipids to renewable diesel. per gallon of gasoline equivalent (GGE) in 2011 dollars for a high-lipid feedstock.
These juvenile traits may reduce the recalcitrance of biomass to conversion into fermentable sugars. Studies have consistently shown that biofuels derived from lignocellulosic biomass could be produced in the United States in a sustainable fashion and could replace today’s gasoline, diesel and jet fuels on a gallon-for-gallon basis.
Novel Biological Conversion of Hydrogen and Carbon Dioxide Directly into Biodiesel. Johnson Matthey will investigate the catalytic conversion of this microbial biodiesel into additional fuel molecules, most importantly jet fuel. Easel Biotechnologies, UC Davis). OPX Biotechnologies Inc. NREL, Johnson Matthey Catalysts).
A small gasoline engine provides power for the vehicle over longer distances, much like the Toyota Prius. First customers for the conversions of several dozen SUVs would be cities, utilities, CEOs, entrepreneurs and celebrities. Plug-in hybrids can be charged from an outlet and have greater range in all-electric mode.
Scientist have confirmed that unlike gasoline cars, plug-ins will get cleaner as they get older -- because our power grid is getting cleaner. The comparison keeps being raised, though studies are conclusive: The "well-to-wheel" emissions of electric vehicles are lower than those from gasoline internal combustion vehicles.
When Straubel—also known for his 1984 Porsche 944 EV conversion—left Tesla, he founded Redwood Materials , a leading lithium battery recycling company in Carson City, Nevada. That was quite a conversion.” Wright also developed the Wrightspeed X1 , an EV sports car known for beating gasoline-powered sports cars in a drag race.
Several after-market companies have done PHEV conversions of the Ford Escape hybrid and one has done a retrofit of the F-150 pickup -- see Where PHEVs Are and ICE-Conversions.) Company says its focusing on gasoline and hydrogen. Has shown some concept fuel-cell PHEVs. First Escape PHEV delivered to SCE Nov 2007; 20 in 2008-2009.
and UC-Davis Emeritus and Catherine JJ DeMauro. Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars. Since it can refuel from a standard household outlet and from a gasoline station, it needs no new infrastructure.
Biofuel projects are going to have trouble getting financing from Wall Street this year because all of them have questions about the long term pricing of petroleum; most of them have concerns about the pricing stability of their feedstocks; and many of the cellulosic projects have concerns about the conversion technologies.
Conversely, engine cold-start at high altitudes dictates an early park position of the intake camshaft, increasing the effective compression ratio of the engine. and Davis, R. liter range extender engine. In designing the second-generation system, GM engineers built on the knowledge and data gained from the first-generation Volt.
This stockholder proposal is proposed by Landry Purcell, who’s representative Dr. Devra Davis has prepared a pre-recorded message Devra Davis: I am Devra Davis, founder of Environmental Health Trust. Brandon Erhart: Thank you, Dr. Davis. Our board has recommended against for the reasons set forth in the proxy.
