Abstract
Processes for forming carbon disulfide from a gas stream containing hydrogen sulfide. A gaseous stream comprising lower molecular weight alkanes and hydrogen sulfide may be contacted with sufficient bromine at a temperature of from about 250° C. to about 530° C. to convert substantially all of said hydrogen sulfide to carbon disulfide. The gaseous stream may contain from about 0.001 to about 20 mol % hydrogen sulfide. The molar ratio of bromine to hydrogen sulfide may be about 2:1.
