Problem to be Solved To provide a catalyst for obtaining hydrogen gas by steam reforming of a hydrocarbon-containing gas in the presence of steam, the catalyst having a high ratio of conversion into hydrogen gas, being capable of preventing deposition of ammonia gas or carbon, having excellent stability even after being reacted for a long time, and allowing a reduction in costs. Solution The foregoing problem is solved by steam reforming catalyst, comprising active metals supported on an ±-alumina carrier,
wherein the active metals comprise 0.1 to 0.3 parts by weight of rhodium (Rh) based on the content of the metal, relative to 100 parts by weight of the ±-alumina carrier, and 0.01 to 0.3 parts by weigh of platinum (Pt) based on the content of the metal, relative to 100 parts by weight of the ±-alumina carrier, and
the ±-alumina carrier is a carrier modified with a promoter comprising 1 to 10 parts by weight of cerium (Ce) based on the content of the metal, relative to 100 parts by weight of the ±-alumina carrier, and
wherein said catalyst is for steam reforming of a desulfurized hydrocarbon-containing gas. |
