Abstract: The invention relates to a shell catalyst with a core and at least one shell surrounding the core, said core being composed of an inert carrier material, and the at least one shell being composed of a porous carrier substance. The shell is physically adhered to the core and the at least one shell contains a catalytically active metal selected from the group of metals of the 10 and 11 group of the periodic table of elements in a finely divided form, or a precursor of the catalytically active metal in a uniformly divided form. The inventive shell catalyst is suitable for reducing unsaturated hydrocarbons and allows for better selectivities in comparison with shell catalysts known so far. The invention further relates to a method for producing the inventive shell catalyst.
