Abstract: The invention relates to a moulded, activated metallic fixed-bed catalyst having a pore volume of 0.05-1 ml/g and an outer, activated shell consisting of a sintered, small-particle catalyst alloy as well as optional catalyst promoters. The catalyst alloy has metallurgical phase domains resulting from the production of the alloy. The phase with the greatest volume has a specific interfacial density of more than 0.5 mu m .

Abstract: The invention relates to a process for the selective catalytic hydrogenation of the carbonyl group of aromatic aldehydes of the formula in which X can be a carboxyl group, a methyl group or halogen, to give the corresponding alcohols and methyl compounds. The catalytic hydrogenation is carried out with the addition of a solvent, if appropriate in the presence of organic acids, on a shaped supported catalyst containing a metal from the platinum group on a titanium oxide support in the presence of hydrogen at partial pressure of hydrogen of 5 to 50 bar and temperatures of from 100 to 300@C.
