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.
Claims20
A process for hydrogenating organic compounds which comprises contacting at least one hydrogenatable organic compound with hydrogen in the presence of a supported coprecipitated catalysts comprised of:
- (a) one or more metals selected from the nonferrous metals of Group VIII of the Periodic Table of the Elements,
- (b) aluminum,
- (c) porous particles, and
- (d) one or more metals selected from Group IIA of the Periodic Table of the Elements, said catalyst being characterized as having a B.E.T. total surface area ranging from about 150 to about 350 m.sup.2 /g, wherein the total amount of Group VIII metal in the catalyst ranges from about 25 wt. % to about 70 wt. %, and the total amount of the Group IIA metal in the catalyst is up to about 10 wt. %, both amounts of metals being based on the total weight of the catalyst after calcination and reduction, and wherein said catalyst has been prepared by coprecipitating the aluminum ions, the Group IIA and Group VIII metal ions with the solid porous particles.
