Abstract
The invention relates to a shaped catalyst body in the form of a tetralobe having four circular through-passages, with the midpoints of the through-passages forming a square and the spacings between in each case two adjacent through-passages being from 0.8 to 1.2 times the thickness of the outer walls of the through-passages. The shaped catalyst body is used for the oxidation of S02 to S03.
