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.
