Aromatization reactions with zeolites containing phosphorus oxide. [C/sub 2/-C/sub 12/ alkanes, C/sub 2/-C/sub 12/ alkenes, C/sub 1/-C/sub 5/ alcohols, and C/sub 2/-C/sub 12/ ethers]
A process is described for producing aromatic hydrocarbons, the process comprising contacting a feedstock comprising one or more non-aromatic compounds selected from the group consisting of C/sub 2/-C/sub 12/ alkanes, C/sub 2/-C/sub 12/ alkenes, C/sub 1/-C/sub 5/ alcohols and C/sub 2/-C/sub 12/ ethers with a catalyst comprising a crystalline zeolite material having the structure of ZSM-5 or ZSM-11, the contacting taking 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 comprising an oxide of phosphorus which has been incorporated into the catalyst by a process comprising the steps of: (i) impregnating the zeolite with a source of phosphate ions; and (ii) calcining the impregnated zeolite of step (i) under conditions sufficient to convert the impregnated phosphate ions to the oxide of phosphorus.
