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.

UC Davis report finds LCFS compliance costs may rise rapidly; recommends offsetting measures

Green Car Congress

Obligated parties are upstream producers and importers of gasoline and diesel fuel sold in the state. Several groups have studied potential future compliance scenarios under the LCFS including Boston Consulting Group (2012) and ICF International (2013). The program is agnostic as to which fuels can be used to meet the Standard.
