Claim:
A process for preparing a catalyst which comprises at least one metal of Group VIII of the Periodic Table of the Elements as a hydrogenating metal and additionally a promoter metal of Groups VIII, IB, or IIB of the Periodic Table of the Elements on an oxidic support, wherein at least 80% of the metal of group VIII of the Periodic Table of the Elements is present in substantially homogeneous distribution in a layer between the surface of the catalyst and a penetration depth which corresponds to not more than 80% of the radius of the catalyst, calculated from the surface of the catalyst, and the promoter is present in substantially homogeneous distribution over the entire cross section of the catalyst, in which an oxidic support is impregnated with a solution consisting of nitrate and nitrite salts of metals of group VIII of the Periodic Table of the Elements, nitrates of the promoter metal, and nitric acid, and wherein the solution has been acidified with the nitric acid to have a pH of at most 5, dried and calcined.
