Catalyst for the desulfurization of industrial waste gases and process for its preparation

摘要

Industrial waste gases containing objectionable/polluting compounds of sulfur, e.g., H2S, SO2 and such organosulfur derivatives as COS, CS2 and mercaptans, are catalytically desulfurized, e.g., by Claus process, employing an improved catalyst comprising titanium dioxide and calcium, barium, strontium or magnesium sulfate.
