ABSTRACT:
A method of producing a catalyst comprising impregnating shaped carriers of refractory material (e.g., alumina) with a solution of the salts of an active metal constituent (e.g., nickel) and an acidic or amphoteric constituent (e.g., uranium), the shaped carriers being fired to decompose the salts to form the oxide of the metal constituent and a compound or solid solution of the oxides of an active metal and acidic or amphoteric constituents, the active components of the catalyst being formed by reduction of the said oxides and/or compound or solid solution in a reducing atmosphere to form the active metal and the acidic or amphoteric constituent in a reduced or unreduced state, the shaped carriers then being impregnated with a water soluble compound of alkali or alkaline earth metal (e.g. barium hydroxide) and finally fixed as the carbonate by heating in an atmosphere containing CO.sub.2.
