    摘要： Sulfur containing organics, e.g., carbon disulfide carbon oxysulfide, or a mercaptan, are oxidized to sulfur dioxide in gaseopus phase, whether alone or conjointly with hydrogen sulfide and/or elemental sulfur, per se, by passing a gaseous stream thereof, at elevated temperature, over a catalyst composition which comprises (i) a carrier substrate comprising titanium oxide, silica, zirconium oxide, silica-magnesia, silica-zirconia, silica-titanium oxide, zirconia-titanium oxide, or a zeolite, or admixture thereof, and (ii) a catalytically effective amount of at least one catalytically active element of Group Ib, IIb, IIIb, Vb, VIb, VIIb, VIII or Va of the Periodic Table, e.g., copper, silver, zinc, cadmium, yttrium, a lanthanide, chromium, molybdenum, tungsten, manganese, iron, cobalt, rhodium, iridium, nickel, palladium, platinum, tin and/or bismuth, but said catalyst composition being devoid of mixed oxide of spinel type.
