China team directly synthesizes gasoline- and diesel-range alkanes from acetone from biomass

Green Car Congress

Researchers in China have directly synthesized gasoline- and diesel-range C 6 -C 15 branched alkanes in high carbon yield (~80%) via the self-condensation of acetone and the subsequent hydrodeoxygenation over a dual-bed catalyst system. A paper on their work appears in the RSC journal Green Chemistry. Sheng et al. Click to enlarge.

China Lake team devises new class of bio-based high-cetane renewable diesel fuels: dioxolanes

Green Car Congress

Researchers at the Naval Air Warfare Center, China Lake have synthesized a new class of renewable diesel fuels from a methyl ketone and diols including 2,3-butanediol, 1,2-propanediol, and ethylene glycol. These values are 20–30 units higher than conventional biodiesel and 40–50 units higher than petroleum-derived diesel fuel.
