The present invention relates to a catalyst for reforming a hydrocarbon comprising a carrier containing manganese oxide and carried thereon (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 a process for producing the same and to a process for reforming a hydrocarbon (steam reforming, self thermal reforming, partial oxidation reforming and carbon dioxide reforming) using the above catalyst. Provided are a catalyst for reforming a hydrocarbon which comprises ruthenium, platinum, rhodium, palladium, iridium or nickel as an active component and in which a reforming activity is elevated, a process for producing the same, and a steam reforming process, a self thermal reforming process, a partial oxidation reforming process and a carbon dioxide reforming process for a hydrocarbon using the above catalyst.

Catalyst for reforming hydrocarbon and method for preparation thereof, and process for reforming hydrocarbon using said catalyst

A catalyst for reforming a hydrocarbon with steam has a platinum group metal deposited on a carrier having a volume of pores with pore sizes of 500 Angstroms or smaller being 0.15 ml per gram or greater, a volume of pores having pore sizes of more than 500 Angstroms being 0.14 ml per gram or smaller, and an average pore size being 90 Angstroms or greater. The platinum group metal specifically includes rhodium and ruthenium, and the carrier preferably includes zirconia and stabilized zirconia. As a promoter component, at least one metal of cobalt and manganese is used. The catalyst is high in catalytic activity and long in catalytic life.
