Claims4
A shaped catalyst for heterogeneously catalyzed reactions in the form of hollow cylinders or annular tablets wherein in cross section the outer wall (outer boundary) and the inner wall (boundary of the central hole) are largely flat and parallel to one another, while the end faces are rounded over their entire area so that, viewed along the central hole, the catalyst body tapers both to the outer boundary and to the boundary of the central hole.
