PURPOSE:To obtain the titled high-activity composition which is highly resistant to poisoning and has excellent mechanical strength by kneading fibrous clay and fine particles of amorphous inorganic oxide which are previously calcined along with water, molding the kneaded material, then drying and calcining, impregnating the calcined material with the metallic component of catalyst, drying, and calcining. CONSTITUTION:The composition contains particles, which are obtained by dispersing fine particles of precalcined amorphous inorganic oxide (e.g., alumina) into fibrous clay such as sepiolite in 10:1-1:10 weight ratio, and the metallic component of the active hydrogenation catalyst such as Mo. The volume of the fine pore is in the range of 0.6- 1.5cc/g, and at least 30% of the fine pore volume is regulated to have >=200Angstrom fine pore diameter. The mean fine pore diameter is regulated to >=200Angstrom . In the manufacture of the titled composition, the fibrous clay and the fine particles of the precalcined amorphous inorganic oxide are mixed, and kneaded in the range of 40-80wt% water content. The kneaded material is molded into the specified shape, and the molded body is dried and calcined. The calcined material is impregnated with the metallic component of the catalyst, and the impregnated material is dried and calcined.
