Abstract

Abstract Supported coprecipitated catalysts comprised of one or more metals of Group VIII, one or more metals of Group IIA, and aluminum are used for hydrogenating hydrogenatable organic compounds. The catalysts are produced by preparing, under agitation; an aqueous mixture containing ions of Group VIII, Group IIA, and aluminum, as well as solid porous particles to form a coprecipitate of the metal ions and aluminum ions with the solid porous support particles; heating the aqueous reaction mixture; and adding precipitating agent to precipitate the metal ions and aluminum ions onto the solid support.
