University of Wisconsin seeking commercial partners for alkylphenol solvent-based method to convert biomass into furan derivatives for fuels and chemicals

Green Car Congress

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners for a novel, cost-effective method developed by University of Wisconsin, Madison researchers for producing furan derivatives such as hydroxymethylfurfural (HMF), furfural, levulinic acid (LA) or γ-valerolactone (GVL) from biomass using alkylphenols as solvents.

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

Reaction pathways for conversion of GVL to butenes and CO 2 , and the integrated conversion of GVL to both a liquid stream of alkenes for use in transportation fuels and a gaseous stream rich in CO 2 that is appropriate for further processing options. James Dumesic, have developed a process to convert aqueous solutions of ?-valerolactone

UW Madison chemists discover new way to harness energy from ammonia

Green Car Congress

A research team at the University of Wisconsin–Madison has identified a new way to convert ammonia to nitrogen gas through a process that could be a step toward ammonia replacing carbon-based fuels. For a fuel cell, we want an electrical output, not input. This is the first process, as far as we know, to do that.

UW Madison, ExxonMobil researchers convert alcohols to diesel-range ethers and olefins

Green Car Congress

Researchers from the University of Wisconsin Madison and ExxonMobil Research and Engineering have devised a two-stage process by which an alcohol such as ethanol or 1-butanol can be converted with high yields into distillate-range ethers and olefins by combining Guerbet coupling (the coupling of two alcohol molecules) and intermolecular dehydration.

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

Strategy for the conversion of solid cellulose to liquid hydrocarbon fuels. A Ru/C catalyst converts the formic acid in the mixture to CO 2 and H 2 , combined with the reduction of levulinic acid to GVL; the H 2 released by the decomposition of formic acid is utilized in the catalytic reduction of levulinic acid.
