摘要： A process for desulfurizing a hydrocarbon stream which includes at least 100 ppmw sulfur in the form of organic sulfur compounds, and C.sub.4 -hydrocarbons. The hydrocarbon stream is contacted in the absence of added hydrogen with a fluidized bed of an acidic catalyst having a structure of ZSM-5, ZSM-11, ZSM-22, ZSM-23, ZSM-35, ZSM-48, MCM-22, MCM-36, MCM-49, zeolite Y, zeolite beta or mixtures thereof to convert the organic sulfur compounds to hydrogen sulfide. The catalyst contacts the hydrocarbon stream at a pressure of from 0.0 psig to about 400 psig, a temperature of from about 400.degree. F. to about 900.degree. F., and a weight hourly space velocity of from about 0.1 hr..sup.-1 to about 10.0 hr..sup.-1. Thereafter, the hydrogen sulfide is removed from the hydrocarbon stream.
