摘要

Frankfurt, 07.08.1990 PAT/bin-rg Hoe90/YO11 Hoechst Aktiengesellschaft, Frankfurt am Main 80 The present invention relates to supported catalysts containing nickel, magnesium oxide, if desired, further additives, which contain Mg and Ni in a reduced form in a molar ratio of (0.0075 to 0.075) : 1, and have an active nickel metal surface area of 110 to 180 m2/g of Ni and a BET total surface area of 160 to 450 m2/g of catalyst. The invention furthermore relates to a process for the preparation of the catalysts and to their use as catalysts for the hydrogenation of aliphatic and/or aromatic hydrocarbons.
