ABSTRACT:
A process for the production of sulfuric acid for using a gas containing sulfur dioxide in a high concentration which comprises using a catalyst consisting of vanadium pentoxide as a main catalytic component, potassium sulfate as a promotor and a diatomaceous earth carrier, wherein a ratio of K.sub.2 O(mol)/V.sub.2 O.sub.5 (mol) is 3.8 to 5.5, V.sub.2 O.sub.5 content is 5.5 to 7.5% by weight and sum of a value of said ratio and the V.sub.2 O.sub.5 content (% by weight) is 9.3 to 11.
