Abstract: The invention relates to shaped catalyst bodies for the oxidation of SO2 to SO3, which comprise vanadium, at least one alkali metal and sulfate on a silicon dioxide support material, wherein the shaped body has the shape of a cylinder having 3 or 4 hollow-cylindrical convexities, obtainable by extrusion of a catalyst precursor composition comprising vanadium, at least one alkali metal and sulfate on a silicon dioxide support material through the opening of an extrusion tool, wherein the opening of the extrusion tool has a cross section formed by 3 or 4 partly overlapping rings whose midpoints lie essentially on a circular line having a diameter of y, wherein the rings are bounded by an outer line lying on a circle having an external diameter x1 and an inner line lying on a circle having an internal diameter x2.

Abstract: The present invention relates to a composition comprising a) a molding comprising a zeolitic material having an AEI-type framework structure, wherein the zeolitic material has a framework structure comprising Si, a trivalent element X, and oxygen, wherein the zeolitic material further comprises one or more alkali metals AM and/or one or more alkaline earth metals AEM; and b) a mixed metal oxide comprising chromium, zinc, and aluminum; and to a process for its production, as well as to the molding and the mixed metal oxide as such, respectively, as obtainable or obtained according to the inventive production process, as well as to the composition as obtainable or obtained according to the inventive production process. In addition to these, the present invention further relates to the use of the inventive composition as a catalyst or as a catalyst component, as well as to a process for preparing C2 to C4 olefins from a synthesis gas comprising hydrogen and carbon monoxide.
