Abstract
Dialkyl disulfide waste, such as that formed in a caustic wash process for removing mercaptans from a hydrocarbon stream, is converted to hydrogen sulfide and valuable hydrocarbons by catalytic contact with a highly siliceous zeolite catalyst exemplified by ZSM-5. The hydrogen sulfide in turn is readily converted to marketable sulfur, thus alleviating the waste disposal problem.
