ABSTRACT:
Industrial waste gases containing objectionable/polluting compounds of sulfur, e.g., H.sub.2 S, SO.sub.2 and such organosulfur derivatives as COS, CS.sub.2 and mercaptans, are catalytically desulfurized, e.g., by Claus process, employing an improved catalyst comprising titanium dioxide and calcium, barium, strontium or magnesium sulfate.
