  • Layered double hydroxide precursor, their preparation process and catalysts prepared therefrom
    Patent number: 11993519
    Abstract: New layered double hydroxide materials useful as intermediates in the formation of catalysts are described, as well as methods of preparing the layered double hydroxides. Also described are catalysts suitable for catalysing the hydrogenation of CO2 to methanol, as well as methods for preparing the catalysts. The LDH-derived catalysts of the invention are active in the hydrogenation of CO2 to methanol, and show improved activity with respect to Cu/ZnO catalysts derived from copper-zinc hydroxycarbonate precursors.
    Type: Grant

    Date of Patent: May 28, 2024
    Assignees: Oxford University Innovation Limited, SCG Chemicals Co., Ltd.
    Inventors: Dermot O'Hare, Shik Chi Tsang, Meng-Jung Li
  • CATALYTIC PROCESS
    Publication number: 20210371754
    Abstract: A catalytic process for the deoxygenation of an organic substrate, such as a biomass or bio-oil, is described. The catalytic process is conducted in the presence of a gaseous mixture containing both hydrogen and nitrogen. The presence of nitrogen in the gaseous mixture gives rise inter-aliato increased catalytic activity and/or increased selectivity for aromatic reaction products.
