Abstract: A novel supported catalyst is described. The catalyst contains (a) a ceramic sponge support having internal surfaces comprised of the walls of cavities randomly dispersed throughout the sponge support and the walls of intersticial passageways connecting said cavities; (b) a first layer of either nickel, copper or cobalt substantially uniformly deposited on and adherent to all internal surfaces of the ceramic sponge support; (c) a second layer comprising a lattice network of either nickel, copper or cobalt adherent to and on the surface of said first layer; and (d) a sufficient quantity of either aluminum, magnesium or zinc intermittently dispersed throughout the second layer to retain the integral structure of said lattice network. The catalyst exhibits increased efficiency over prior art catalysts when used in similar capacities.
