Abstract: Metal catalysts consist of hollow molds. An Independent claim is also included for the production of metal catalysts comprising spraying metal powders together with a binder onto molds made of combustible material, i.e. polystyrene, and calcining the material forming the hollow mold. Preferred Features: The catalysts comprise hollow spheres having a diameter of 0.5-20 mm and a wall thickness of 0.1-5 mm. The catalysts have an impermeable casing having an open porosity of maximum 80% and made up of different layers.

Abstract: A process for the preparation of substituted amines by catalytic hydrogenation of substituted organic nitro compounds with hydrogen or hydrogen-containing gas mixtures in the presence of a shaped Raney catalyst as the hydrogenation catalyst, wherein the Raney catalyst is in the form of hollow bodies or shell-activated tablets. Nickel, cobalt, copper, iron, platinum, palladium or ruthenium are preferably used as catalytically active constituents.

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.
