Abstract
A shaped metal fixed-bed catalyst is disclosed which contains at least one catalyst alloy formed of a catalyst metal and an extractable alloying component. The catalyst is activated in an outer layer with a thickness of 0.1 to 2.0 mm starting from the surface by complete or partial extraction of the extractable alloying component. The catalyst may also contain promoters. The catalyst is distinguished from known catalyst in that it is formed exclusively of the catalyst alloy and has a total pore volume of 0.1 to 0.6 ml/g. The catalyst is used for hydrogenation, dehydrogenation and hydrogenolysis reactions.
