Abstract

An activated fixed-bed Raney metal catalyst which is free of metal powder, has macropores and is based on an alloy of aluminum and at least one metal of subgroup VIII of the Periodic Table, contains more than 80% by volume, based on the total pores, of macropores and is used for the hydrogenation of low molecular weight and polymeric organic compounds.
