Univ. of Wisconsin team reports on new process for converting hemicellulose to furfural and levulinic acid as renewable fuel precursors and chemicals

Green Car Congress

Schematic representation of the conversion of hemicellulose to furfural (FuAL) through the biphasic dehydration of xylose to furfural, followed by the production of levulinic acid (LA) by reduction of furfural to furfuryl alcohol (FuOH) and further reaction of furfuryl alcohol with water in a biphasic reactor.

UW-Madison team develops novel hydrogen-producing photoelectrochemical cell using solar-driven biomass conversion as anode reaction

Green Car Congress

Researchers at the University of Wisconsin-Madison have developed an innovative hydrogen-producing photoelectrochemical cell (PEC), using solar-driven biomass conversion as the anode reaction. Examples include the reduction of water to give H 2 and the reduction of CO 2 to give carbon-based fuels such as methanol and methane.

UW-Madison Team Shows Good Yield of Renewable Diesel and Jet Hydrocarbons from Processing of Biomass-Derived GVL

Green Car Congress

Reaction pathway for conversion of GVL to liquid transportation fuels. Alcohols in the feed, such as 5-nonanol, can present a problem for oligomerization, because they undergo dehydration under reaction conditions to produce water, which has a strongly inhibiting effect on the rate of alkene oligomerization.
