ABSTRACT:
Supported coprecipitated non-ferrous Group VIII metal aluminum catalysts are disclosed. The catalysts are produced by preparing an aqueous mixture containing the metal ions, aluminum ions and solid porous support particles under agitation 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 further precipitate the metal ions and aluminum ions onto the solid support.
