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

GC-MS chromatogram of the liquid products obtained after hydrodeoxygenation of angelica lactone dimer. Considering that levulinic acid is available with more than 80% conversion from raw biomass, a field-to-tank yield of drop-in, cellulosic gasoline of more than 60% is possible, the researchers claimed.

Waste gasification company Sierra Energy closes $33M Series A funding; FastOx

Green Car Congress

At the lowest point of the gasifier, the waste is reduced to carbon char, inorganic materials, and metals. Injected oxygen and steam react with the carbon char to produce a synthesis gas (syngas), comprised predominately of carbon monoxide and hydrogen. Sierra Energy was founded in Davis, California in 2004.
