  • Stabilized nickel-containing catalysts and process for production of syngas
    Patent number: 6911161
    Abstract: A method is disclosed for converting light alkanes (e.g. methane or natural gas) to synthesis gas employing a stabilized Ni-based catalyst that is active for catalyzing the net partial oxidation of the hydrocarbon, in the presence of O2 to CO and H2. Certain preferred catalysts comprise Ni alloyed with a Ni-stabilizing amount of gold or silver, and a lanthanide element, carried on a refractory support.
    Type: Grant
    Filed: July 2, 2002
    Date of Patent: June 28, 2005
    Assignee: ConocoPhillips Company
    Inventors: Bang C. Xu, Sriram Ramani, Sergej A. Maslov

  • Promoted cobalt-chromium oxide catalysts on lanthanide-modified supports and process for producing synthesis gas
    Publication number: 20030103892
    Abstract: Catalysts comprising promoted cobalt-chromium oxide disposed on a lanthanide coated refractory support that are active for catalyzing the net partial oxidation of methane or natural gas to products containing CO and H2 are disclosed, along with short contact time processes employing the new catalysts for producing synthesis gas. Preferred promoters are rhodium and cerium, and a preferred lanthanide coating material is ytterbium.
