Catalyst for removing metal carbonyl, process for producing mixed reformed gas containing hydrogen, process for removing metal carbonyl, and fuel cell system

Abstract

The present invention relates to a catalyst for removing a metal carbonyl which comprises a nickel-containing catalyst component and copper, said copper being present in an amount of 0.001 to 250% by weight in terms of metallic copper on the basis of a weight of the nickel contained in the catalyst component. The catalyst may further contain, if required, zinc oxide, a clay mineral, or a clay mineral supporting at least one element having an average particle diameter of not more than 50 nm which is selected from the group consisting of ruthenium, rhodium, iridium, platinum, gold, silver, palladium, nickel, cobalt, copper, iron, zinc, vanadium and manganese. When using the catalyst, it is possible to produce a mixed reformed gas from hydrocarbons, and remove a metal carbonyl in a reforming reaction field.
