Abstract
An excellent steam reforming catalyst for hydrocarbons is provided having at least one of nickel oxide, cobalt oxide and platinum group noble metals supported on a carrier consisting essentially of aluminum oxide Al.sub.2 O.sub.3 and a metal oxide expressed by MeO, comprising about 3-35 mols of metal oxide MeO to 100 mols of aluminum oxide Al.sub.2 O.sub.3 in the carrier, Me being at least one metal selected from the group consisting of calcium Ca, barium Ba and strontium Sr. The catalyst exhibits high activity, superior mechanical strength, good heat resistant property, splendid chemical stability, and remarkable thermal shock resistant property, retains a high specific surface area at high temperatures, and does not form detrimental nickel aluminate or cobalt aluminate in steam reforming reactions of hydrocarbons. A method of producing the catalyst is also provided.
