PURPOSE: To enhance the conversion rate or the like of an org. sulfur compd. by forming a gas treating catalyst of a recessed surface multilobular shape contg. a catalytically active element to a Claus reaction and/or hydrolysis of the org. sulfur compd. CONSTITUTION: The catalyst for treating the gaseous effluent is produced by impregnating a refractory carrier consisting of alumina, silica, cerium oxide, zirconium oxide, titanium oxide or the like with the catalytically active element. In such a case, the shape of the catalyst carrier is required to be formed to the recessed surface multilobular shape and the cross-sectional surface thereof is adequately a circular shape of 2 to 9 m in diameter and is more adequately an ellipse of a major axial line of 2 to 9 mm in cross-section and a minor axial line of 1.2 to 7 mm. Aluminum oxide, titanium oxide, cerium oxide or zirconium oxide alone or the mixture composed thereof is used as the catalytically active element. The content thereof is adequately specified to 60 to 99% of the entire weight of the catalyst.
