  • Compounds and methods for the production of long chain hydrocarbons from biological sources
    Patent number: 9422207
    Abstract: The present invention is directed to the preparation of oxygenated, unsaturated hydrocarbon compounds, such as derivatives of furfural or hydroxymethyl furfural produced by aldol condensation with a ketone or a ketoester, as well as methods of deoxidatively reducing those compounds with hydrogen under acidic conditions to provide saturated hydrocarbons useful as fuels.
    Type: Grant
    Filed: September 14, 2012
    Date of Patent: August 23, 2016
    Assignees: Los Alamos National Security, LLC, The Proctor & Gamble Company

  • Catalytic reduction of ketones and aldehydes using organometallic ruthenium complexes
    Patent number: 6462206
    Abstract: Ketones and aldehydes are hydrogenated to the corresponding alcohol or alkyl group, using H2 gas as the stoichiometric reductant, and organometallic ruthenium complexes as the catalysts.
