  • Catalytic biomass conversion methods, catalysts, and methods of making the same
    Patent number: 9783474
    Abstract: Described herein are processes for one-step delignification and hydrodeoxygenation of lignin fraction a biomass feedstock. The lignin feedstock is derived from by-products of paper production and biorefineries. Additionally described is a process for converting biomass-derived oxygenates to lower oxygen-content compounds and/or hydrocarbons in the liquid or vapor phase in a reactor system containing hydrogen and a catalyst comprised of a hydrogenation function and/or an oxophilic function and/or an acid function. Finally, also described herein is a process for converting biomass-derived oxygenates to lower oxygen-content compounds and/or hydrocarbons in the liquid or vapor phase in a reactor system containing hydrogen and a catalyst comprised of a hydrogenation function and/or an oxophilic function and/or an acid function.
    Type: Grant

  • PRODUCTION OF RENEWABLE FINE CHEMICALS AND LIQUID FUELS
    Publication number: 20160272665
    Abstract: Described herein is a process for conversion and upgrading of biomass to products. The process involves converting the biomass to primary lignin-derivatives and primary cellulose/hemicellulose derivatives, catalytically treating the primary lignin-derivatives to produce secondary lignin-derived products, and treating the primary cellulose/hemicellulose- derivatives to produce secondary cellulose/hemicellulose-derived products.
