PURPOSE:To obtain a catalyst for having excellent durability, activity and mechanical strength for hydrogenation of a heavy gravity hydrocarbon oil by consisting said catalyst of fibrous clay mineral consisting essentially of Mg silicate and inorg. oxide. CONSTITUTION:1-100pts.wt. times of water is added to fibrous clay mineral (e.g., sepiolite) having a double chain structure consisting essentially of Mg silicate and is strongly agitated until an increase in viscosity of the formed pasty material with time is eliminated, thereby forming the pasty material of the clay mineral in which the fiber bundles are highly opened. Inorg. oxide such as silica or inorg. hydroxide such as boehmite is uniformly mixed therewith and the mixture is dehydrated to 40-80wt% moisture. The dehydrated mixture is molded, dried and calcined at 200-800 deg.C. As a result, the compsn. in which the pore volume of the entire compsn. is larger by at least 0.05cc/g than the arithmetic weighted mean of the pore volume possessed by the above-described fibrous clay mineral and inorg. oxide is obtd.
