Abstract

A process for the preparation of a hydrogenation catalyst which contains the oxides of the metals nickel, copper, molybdenum and aluminum and/or iron, and may or may not contain manganese oxide, by precipitating a solution of salts of the metals with an alkali metal carbonate at from 35.degree. to 95.degree. C. and a pH of from 5 to 9 and heating the precipitate at from 350.degree. to 700.degree. C., the amount of the metal salts being selected so that the catalyst contains from 5 to 70 percent by weight of aluminum oxide and/or iron oxide, the remainder being principally nickel oxide and, based on nickel oxide, from 20 to 40 percent by weight of copper oxide, from 0.5 to 6 percent by weight of molybdenum oxide and from 0 to 10 percent by weight of manganese oxide.
