Abstract: In a coated catalyst having a core and at least one shell surrounding the core, the core is made up of an inert support material, the shell or shells is/are made up of a porous support substance, with the shell being attached physically to the core, and a catalytically active metal selected from the group consisting of the metals of the 10th and 11th groups of the Periodic Table of the Elements is present in finely divided form or a precursor of the catalytically active metal is present in uniformly distributed form in the shell or shells. The coated catalyst of the present invention is suitable for the reduction of unsaturated hydrocarbons. Here, better selectivities than in the case of previously known coated catalysts can be achieved. A process for producing the coated catalyst is also described.

Abstract: The invention relates to a process for the selective hydrogenation of alkynes and dienes in C2-C5+-olefin mixtures,-in C2- or C3-streams of the olefin preparation by cracking. The method comprises conducting the hydrogenation in the presence of a catalyst particle comprising (a) a metal of the tenth group of the Periodic Table, (b) a metal of the eleventh group of the Periodic Table and (c) optionally a compound of a metal of the first or second group of the Periodic Table. Components (a) and (b), and optionally (c), are applied to a support selected from the group consisting of silica, titanium dioxide, zirconium oxides, spinels, zinc aluminates, zinc titanate, aluminosilicates and mixtures thereof. The metal of the eleventh group is distributed homogeneously over the cross-section of the catalyst particle, and the metal of the tenth group is present in an edge layer close to the surface of the catalyst particle.
