Kind Code: A1 A steam reforming catalyst comprising ruthenium as an active component, improving the steam reforming activity of various hydrocarbons and having a small amount of carbon deposition, a method for producing the same, and a method for steam reforming a hydrocarbon using the catalyst. provide. And a hydrocarbon reforming catalyst having improved reforming activity, comprising ruthenium, platinum, rhodium, palladium, iridium or nickel as an active component, and a method for producing the same, and a hydrocarbon steam reforming method using the catalyst, self A thermal reforming method, a partial oxidation reforming method, and a carbon dioxide reforming method are provided. A carrier containing manganese oxide and alumina carries (a) at least one component selected from a ruthenium component, a platinum component, a rhodium component, a palladium component, an iridium component, and a nickel component, and oxidation in the carrier. A hydrocarbon steam reforming, autothermal reforming or partial oxidation reforming catalyst having an amount of manganese of 5 to 95% by mass. [Selection] Figure 1 |
