Chu, C -C

A process is described for producing aromatic hydrocarbons, the process comprising contacting a feedstock comprising one or more of ethylene, propane and propylene with a catalyst comprising a crystalline zeolite material having the structure of ZSM-5 or ZSM-11. The contacting takes place under sufficient aromatization conditions including a temperature of from about 100/sup 0/C to about 700/sup 0/C, a pressure of from about 0.1 atmosphere to about 60 atmospheres, a weight hourly space velocity (WHSV) of from about 0.1 to about 400 and a hydrogen/hydrocarbon mole ratio of from about 0 to about 20, the feedstock further comprising from about 2 to about 50 volume percent of hydrogen sulfide in an amount sufficient to increase the proportion of benzene in the aromatic hydrocarbons produced.
