Chu, C C

A process is described for producing aromatic hydrocarbons. The process comprises contacting a feedstock consisting of one or more non-aromatic compounds selected from the group consisting of C/sub 2/-C/sub 12/ alkanes and C/sub 2/-C/sub 12/ alkenes with a catalyst comprising a crystalline zeolite material having the structure of ZSM-5 or ZSM-11. The contacting takes place under aromatization conditions including a temperature of from about 200/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 catalyst further comprises an oxide of phosphorus which has been incorporated into the catalyst. This process is also given.
