Abstract:
A method of converting a reactant gas mixture comprising C1-C5 hydrocarbons and O2 into a product gas mixture comprising H2 and CO in a molar ratio of about 1.5:1 to about 2.3:1 comprising contacting the reactant gas mixture at partial oxidation promoting conditions of temperature, pressure and feed flow rate with a catalyst comprising a catalytically active component selected from the group consisting of rhodium, platinum, ruthenium, iridium, rhenium, and combinations thereof, supported on a catalyst support chosen from the group consisting ofoxide-dispersion-strengthened alloys comprising aluminum, chromium, and yttrium oxide, at least one metal selected from the group consisting of iron, nickel, and cobalt, and, optionally, titanium, and non-oxide-dispersion-strengthened alloys comprising chromium, aluminum, titanium, an element selected from the group consisting of yttrium, lanthanum and scandium, and at least one metal selected from the group consisting of iron, nickel and cobalt, the catalyst having a metal oxide layer disposed between said catalytically active component and the support.
