Zusammenfassung: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.
