Abstract (en)
1. A process for the production of a hydrogenation catalyst which contains copper, nickel and/or cobalt on a silica carrier, characterized in that an aqueous solution of a salt of copper, nickel and/or cobalt is mixed with an alkali metal silicate solution having a ratio of Me2 O to SiO2 of more than 1:1 (Me denoting potassium or sodium) in such an amount that the mixture has a pH of 6 to 8 and the content of copper, nickel and/or cobalt in the finished catalyst is about 40 to 80% by weight, and, using conventional methods, the precipitate formed on mixing is isolated, moulded, dried and treated with a reducing agent.

Hydrierkatalysatoren mit Kupfer, Nickel oder Kobalt als Wirkmetallen werden durch Fällung der Metallsalzlösungen mit Alkalisilikatlösungen, die überschüssiges Alkali enthalten, und Trocknen sowie Reduzieren der erhaltenen Niederschläge gewonnen.
