Abstract

Raney alloy catalysts applied to a support are described, said catalysts having an extremely thin layer of Raney alloy with a thickness of 0.01 to 100 μm. These catalysts are prepared by vapor deposition of the appropriate metals under reduced pressure. They are generally suitable for all known hydrogenation and dehydrogenation reactions and are extremely abrasion-resistant.
