Abstract
A process for preparing activated carbon supported catalysts by mixing an activated carbon support having acid surface groups with an aqueous solution containing one or more cations selected from the groups IB and VIII of the Periodic System of Elements as well as Zn to effect cation exchange with the acid groups on the surface of the activated carbon support, separating the cation exchanged activated carbon. Said exchanged surface cations are thereafter reduced on the carbon support in the medium which is later to be subjected to the catalyzed reaction. The surface of the activated carbon support may be oxidized to increase the number of acid groups per unit area prior to ion exchange.
