  • Method to make alkanes and saturated polyhydroxy compounds from carbonyl compounds
    Patent number: 7671246
    Abstract: A catalytic process for converting biomass-derived carbohydrates to liquid alkanes, alkenes, and/or ethers is described. The process uses combinations of self- and crossed-aldol condensation reactions, dehydration reactions, and hydrogenation reactions, over specified metal-containing catalysts, to yield alkane, alkene, and ether products from carbohydrate reactants.

  • Catalytic process for producing furan derivatives in a biphasic reactor
    Patent number: 7572925
    Abstract: Described is a catalytic process for converting sugars to furan derivatives (e.g. 5-hydroxymethylfurfural, furfural, dimethylfuran, etc.) using a biphasic reactor containing a reactive aqueous phase and an organic extracting phase. The process provides a cost-effective route for producing di-substituted furan derivatives. The furan derivatives are useful as value-added intermediates to produce polymers, as precursors to diesel fuel, and as fuel additives.
