Abstract
A supported catalyst is prepared by depositing oxides of nickel and cobalt, with or without noble metals, on a sintered low surface area porous inert support, surface of which is precoated with an oxide of Be, Mg, Ca or a mixture thereof so that a protective layer of the alkaline earth oxide is formed between the oxides of nickel and cobalt, with or without noble metal, and the support and hence direct chemical interactions between the oxides of the group VIII transition metals and the reactive components of support, which leads to the formation of catalytically inactive binary oxide phases are avoided.
