Hydrogenation of hydrocarbons with catalysts produced by co-gelling a smectite with an inorganic metal oxide which is unstable with respect to retaining a high surface area, to produce a co-gel of high surface area which has good retention of surface area at high temperatures. Suitable smectites for the practice of this invention are hectorite, chlorite, montmorillionite, beidellite, or admixtures of two or more of these materials with each other or with other materials, or the like. Exemplary of inorganic oxide gels suitable for the practice of this invention are the Group IV-B metal oxides, especially titanium oxide, and other metal oxides such as the oxides of thorium, uranium, silicon, aluminum, and the like. A crystalline aluminosilicate zeolite can be composited with this material to supply an acidic function.
