Abstract
The invention relates to a shaped catalyst body for preparing maleic anhydride, which comprises mixed oxides of vanadium and of phosphorus as catalyst components. To develop a generic shaped catalyst body further so that it has improved properties, it is proposed that the basic geometric body enveloping the shaped catalyst body () be a prism () having a first triangular face and a second triangular face and the shaped catalyst body () be provided with three through openings () which extend from a first face of the shaped body () which contacts the first triangular face of the prism () to a second face of the shaped body () which contacts the second triangular face of the prism ().
