Abstract

A catalyst comprising at least one metal of the 10th group of the Periodic Table of the Elements and at least one metal of the 11th group of the Periodic Table of the Elements on an aluminum oxide support, wherein the metal or metals of the 10th group is or are essentially concentrated in an outer layer close to the surface of the catalyst particle, the metal or metals of the 11th group is or are distributed essentially uniformly over the volume of the catalyst particle and the weight ratio of the metal or metals of the 11th group to the metal or metals of the 10th group is not more than 1.95.
