NON-FERROUS GROUP VIII ALUMINIUM COPRECIPITATED HYDROGENATION CATALYSTS, PROCESS FOR PREPARING THESE CATALYSTS AND THEIR USE IN HYDROGENATION PROCESSES

摘要

Supported coprecipitated non-ferrous Group VIII metal aluminum catalysts are prepared and used for hydrogenating hydrogenatable organic compounds. 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.
