  • Fuels and fuel additives production from glycerol conversion using a monohydric alcohol and heterogeneous catalysis
    Patent number: 8986400
    Abstract: The present disclosure relates to a method of converting glycerol into organic reaction products. The method may include mixing glycerol with a monohydric alcohol. The mixture of glycerol and monohydric alcohol is then reacted in the presence of a heterogeneous nano-structured catalyst, wherein the monohydric alcohol is present at subcritical/supercritical temperatures and pressures. This converts the glycerol into one or more reaction products, wherein the reaction products include an oxygenated organic reaction product. Ninety percent or greater of the glycerol is converted.
    Type: Grant
    Filed: October 17, 2012
    Date of Patent: March 24, 2015
    Assignee: Southwest Research Institute
    Inventors: Maoqi Feng, Chee-Kai Tan

  • Continuous production of bioderived esters via supercritical solvent processing using solid heterogeneous catalysts
    Patent number: 8507702
    Abstract: A method for the continuous production of ester based organic compounds from renewable natural products via supercritical solvent processing in the presence of heterogeneous nano-structured catalysts. Fatty acid triglycerides may therefore be transesterified using heterogeneous nano-structured catalysts in the presence of supercritical alcohols to provide alkyl ester compounds and glycerine.
