Catalytic partial oxidation process and promoted nickel based catalysts supported on magnesium oxide

A process and catalyst are disclosed for the catalytic partial oxidation of light hydrocarbons to produce synthesis gas. The process involves contacting a feed stream comprising the hydrocarbon feedstock and an oxygen-containing gas with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream comprising carbon monoxide and hydrogen in a molar ratio of about 2: 1 H 2: CO. A preferred supported catalyst used in the process includes nickel and magnesium oxide, with a promoter selected from the group including manganese, molybdenum, tungsten, tin, rhenium, bismuth, indium, phosphorus, and combinations thereof.
