  • Porous silica and metal oxide composite-based catalysts for conversion of fatty acids and oils to biodiesel
    Patent number: 7790651
    Abstract: A recyclable esterification or transesterification catalyst and methods for making and using the same are provided herein. The catalyst can be used to prepare biodiesel or methyl soyate from various feedstocks, including vegetable oils and animal fats. The catalyst can both esterify free fatty acids and transesterify mono-, di-, and triglycerides. The catalyst can also be combined with a metal oxide, and optionally calcined, prior to carrying out a catalytic reaction.
    Type: Grant
    Filed: August 18, 2006
    Date of Patent: September 7, 2010
    Assignee: Iowa State University Research Foundation, Inc.
    Inventors: Victor Shang-Yi Lin, Jennifer A. Nieweg, John G. Verkade, Chinta Reddy Venkat Reddy, Carla Kern
