Beschreibung
Zusammenfassung:	Disclosed are catalysts in powdered form comprising a major amount of the oxides of a first metal selected from copper or zinc, a second metal selected from chromium, molybdenum, tungsten and vanadium, and optionally, a minor amount of the oxide of a promoter metal selected from the group consisting of manganese, barium, zinc, nickel, cobalt, cadmium, iron and any combination thereof provided that the promoter metal is not zinc if the first metal is zinc, wherein the average particle diameter of the powder is from about 6 to about 20 microns; and the particle surface area is from about 20 to about 70 m2/g. Also disclosed is a process for preparing such catalysts and a process for hydrogenating aldehydes, ketones, carboxylic acids and carboxylic acid esters with catalysts of the type described.
