CARRYING COBALTTSILICA COPRECIPITATION HYDROGENATING CATALYST

摘要

This invention relates to coprecipitated cobalt-silica hydrogenation catalysts which are prepared by preparing an aqueous reaction mixture containing cobalt cations, silicate anions and solid porous carrier particles under agitation to form a coprecipitate of the cobalt and silicate ions onto said solid porous support particles; heating the aqueous reaction mixture; and adding an alkaline precipitating agent to precipitate further the cobalt and silicate ions onto said solid porous carrier particles. The aqueous reaction mixture may additionally include copper cations.
