  • Renewable engine fuel and method of producing same
    Patent number: 8556999
    Abstract: The present invention provides non-petroleum high-octane fuel derived from biomass sources, and a method of producing same. The method of production involves reducing the biomass feedstocks to sugars, fermenting the sugars using microorganisms or mutagens thereof to produce ethanol or acetic acid, converting the acetic acid or ethanol to acetone, and converting the acetone to mesitylene and isopentane, the major components of the renewable engine fuel. Trimerization of acetone can be carried out in the presence of a catalyst containing at least one metal selected from the group consisting of niobium, iron and manganese. The ethanol can be converted to mesitylene in a dehydration reaction in the presence of a catalyst of zinc oxide/calcium oxide, and unreacted ethanol and water separated from mesitylene by distillation.
    Type: Grant
    Filed: March 4, 2010
    Date of Patent: October 15, 2013
