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 researcher finds ride-hailing EVs offer triple the emissions benefits of a personally owned EV

Green Car Congress

Replacing a gasoline-powered ride-hailing vehicle with an electric vehicle can deliver three times the carbon benefits of a personally owned electric vehicle, according to a study by a University of California, Davis, researcher of Uber and Lyft data. The paper is published in the journal Nature Energy.

Argonne LCA finds renewable diesel from algae fractionation has 63-68% lower GHG than petroleum diesel

Green Car Congress

A new analysis from Argonne National Laboratory, funded by the US Department of Energy’s Bioenergy Technologies Office (BETO), shows the potential of an algae fractionation process to produce renewable diesel fuel with 63%–68% lower greenhouse gas (GHG) emissions than conventional diesel. The study is published in the journal Algal Research.

NREL process boosts production of ethanol from algae

Green Car Congress

A new biorefinery process developed by scientists at the Energy Department’s National Renewable Energy Laboratory (NREL) has proven to be significantly more effective at producing ethanol from algae than previous research. In traditional processes, the algae produce lipids that get converted into fuels. Knoshaug, Ryan Davis, Lieve M.L.

California ARB considering four new low-carbon fuel pathways; Neste renewable diesel and sugarcane molasses ethanol

Green Car Congress

Among the new pathways to be considered is the production of renewable diesel from Australian tallow at Neste Oil’s Singapore plant. The baseline CI value for gasoline is 95.86 Neste Oil renewable diesel: 33.46 produces NExBTL non-ester renewable diesel (RD) from multiple feedstocks at its plant in Singapore. g CO 2 e/MJ.

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. For the ethanol process, the acetic acid is then converted to an ester which is then hydrogenated to make ethanol. ZeaChem Inc., ZeaChem Inc.,

Researchers find new high-yield route for producing key plastic ingredient from biomass

Green Car Congress

Renewable process for production of p-Xylene from glucose. The plastics industry currently produces p -xylene from petroleum; the new renewable process creates exactly the same chemical from biomass. Dauenhauer says this is a major breakthrough since other methods of producing renewable p -xylene are either expensive (e.g.,
