Wisconsin Researchers Devise Process to Convert Biomass Intermediate Product into Drop-in Transportation Fuels Without Use of External Hydrogen or Precious Metal Catalysts

Green Car Congress

Researchers at the University of Wisconsin, led by Dr. James Dumesic, have developed a process to convert aqueous solutions of ?-valerolactone Not requiring hydrogen or precious metal catalysts could contribute to a lower cost for a commercial-scale version of the process than some other renewable hydrocarbon fuel technologies.

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.

New Catalytic Process to Convert Cellulose Into Renewable Diesel and Gasoline

Green Car Congress

Researchers at the University of Wisconsin–Madison led by James Dumesic have developed a catalytic process to convert cellulose into liquid hydrocarbon fuels (diesel and gasoline), using a cascade strategy to achieve the progressive removal of oxygen from biomass, allowing the control of reactivity and facilitating the separation of products.

Solazyme and Amyris receive Presidential Green Chemistry Challenge awards

Green Car Congress

Amyris received the Small Business award for its renewable hydrocarbon farnesane for use as diesel and jet fuel. Farnesene is a building block hydrocarbon that can be converted into a renewable, drop-in replacement for petroleum diesel without certain drawbacks of first-generation biofuels.
