    摘要： The present invention relates to a method for producing a shell catalyst which comprises a porous shaped catalyst support body with an outer shell in which at least one catalytically active species is present. In order to provide a shell catalyst production method by means of which shell catalysts can be produced, said shell catalysts having, over a comparatively large region of their shell thickness, a substantially uniform concentration of catalytically active species and having a substantially uniform shell thickness, what is proposed is a method using an device which is designed to generate, by means of a process gas, a fluid bed of shaped catalyst support bodies in which the shaped catalyst support bodies circulate elliptically or toroidally, preferably toroidally, comprising the steps of charging the device with shaped catalyst support bodies and generating a shaped catalyst support body fluid bed by means of a process gas, the shaped catalyst support bodies circulating elliptically or toroidally in the fluid bed, preferably toroidally; impregnating an outer shell of the shaped catalyst support body with a catalytically active species or precursor thereof by spraying the shaped catalyst support bodies circulating elliptically or toroidally in the fluid bed with a solution comprising a catalytically active species or a precursor thereof; drying the shaped catalyst support bodies sprayed with the solution.
