Abstract: A process of preparing a product gas mixture comprising CO and H2 from a light hydrocarbon and O2 mixture is disclosed. The process includes contacting a reactant gas mixture comprising a C1-C5 hydrocarbon and a source of molecular oxygen with a catalytically effective amount of a supported catalyst comprising nickel and rhodium. The catalyst and reactant gas mixture is maintained at catalytic partial oxidation promoting conditions of temperature and pressure during the contacting period, which is preferably 10 milliseconds or less. Certain preferred catalysts comprise an alloy of about 1-50 weight percent nickel and about 0.01-10 weight percent rhodium on a porous refractory support structure.

Abstract: Mixed metal carbide catalysts that are active for catalyzing the net partial oxidation of methane to CO and H2 are disclosed, along with their method of making. The preferred catalysts of the invention comprise a mixture of at least two carbided metals that are prepared by the reaction of the metal oxides, alkoxides or nitrates with a hydrocarbon of the formula CnH2nnull2 wherein n is an integer from 1 to 4. Optionally, the catalysts include an additional promoter and/or a catalyst support. Preferred catalysts are at least 50 wt % molybdenum, tungsten or chromium, and also contain a second metal selected from the group consisting of molybdenum, tungsten, vanadium, chromium, iron, niobium, tantalum, rhenium, cobalt, copper, tin and bismuth.
