Abstract: A process for producing a metal carbonate-containing shaped catalyst body for the hydrogenation of an organic compound having one or more carbonyl group, in which a) a metal carbonate composition which contains, based on the total weight of the metal carbonate composition, from 70 to 94.5% by weight of a metal carbonate mixture containing two or more than two metal carbonates of two or more than two different metals (M), from 5 to 25% by weight of metallic copper, and from 0.5 to 5% by weight of tableting aid is provided, b) a shaped body is formed from the metal carbonate composition provided in step a), and c) the shaped body obtained in step b) is activated in the presence of hydrogen at a temperature in the range from 150 to 250° C.
