1. Hydrogenation catalyst containing a noble metal of group VIII of the periodic table on aluminium oxide as the support, which is obtainable by impregnating an aluminium oxide support material with an internal surface area (BET) of less than 80 m**2 /g, in accordance with its absorbency, to saturation with an aqueous solution containing an inorganic base, drying the material in a steam of warm air to a residual moisture content of less than 2% by weight and impregnating it in a manner which is in itself known with a noble metal salt solution, 0,1-50 gram equivalents of inorganic base being employed per gram equivalent of noble metal for impregnation, and subjecting the catalyst thus obtained to optional reduction, washing with water and drying. |
