摘要： The invention relates to a shaped catalyst body for the oxidation of SO
2 into SO
3 , containing vanadium, at least one alkali metal, and sulfate on a silicon dioxide substrate material, wherein the shaped body has the shape of a cylinder having 3 or 4 hollow cylindrical protrusions, obtainable by extruding a catalyst precursor mass, comprising vanadium, at least one alkali metal, and sulfate on a silicon dioxide substrate material, through the opening of an extrusion tool, wherein the opening of the extrusion tool has a cross-section that is formed by 3 or 4 rings, the center points of which lie substantially on a circular line having the diameter y and partially overlap each other, wherein the rings are bounded by an outer line lying on a circle having an outer diameter (x1) and an inner line lying on a circle having an inner diameter (x2).
