Abstract: A shaped, activated metal, fixed-bed catalyst with a pore volume of 0.05 to 1 ml/g and an outer activated layer consisting of a sintered, finely-divided, catalyst alloy and optionally promoters. The catalyst alloy has metallurgical phase domains, resulting from the method of preparation of the alloy, in which the largest phase by volume has a specific interface density of more than 0.5 mum-1.
