UC Davis team optimizes levulinic ester self-condensation process for production of cellulosic gasoline

Green Car Congress

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.

UC Davis process produces gasoline-range hydrocarbons from biomass-derived levulinic acid; field-to-tank yield of >60% claimed

Green Car Congress

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).

Researchers explore catalytic partial oxidation reformation of diesel, gasoline, and natural gas for “single-fuel RCCI”

Green Car Congress

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.

ZeaChem signs contract to develop advanced drop-in biofuels beyond cellulosic ethanol

Green Car Congress

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.

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 (?).
