Method for producing a core-shell catalyst

A process for producing an eggshell catalyst, comprising the coating of the outer surface of a geometric shaped support body with

• a) one or more catalytically active multielement oxides and one or more liquid binders, wherein the binder is removed later, or
• b) one or more powders P and one or more liquid binders, wherein the powder P, after the coating, is converted by thermal treatment to one or more catalytically active multielement oxides,
• wherein the coating is conducted in a horizontal mixer and the Froude number during the coating in the horizontal mixer is from 0.0040 to 0.1200.
