Abstract (en)

[origin: WO2012140613A1] Disclosed a shaped catalyst body for preparing ethylene oxide, which comprises at least silver and rhenium applied to an alumina support, and also a process for producing it, wherein the alumina support has the geometry of a hollow cylinder and the shaped catalyst body has a rhenium content CR and CR/ppm by weight, based on the wall thickness of the hollow cylinder dw in mm, and calculated as element, in the range 120=CR/dw=200.
