Chu, C -C

A process is described for producing aromatic hydrocarbons, the process comprising contacting one or more C/sub 2/-C/sub 12/ alkanes 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 spaced 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 a Group IIIA, IVA or VA element, the oxide being incorporated into the catalyst by a modification process comprising the steps of: (i) contacting the ZSM-5 or ZSM-11 with a solution or neat liquid of a compound of the Group IIIA, IVA or VA element, thereby impregnating the ZSM-5 or ZSM-11 with the compound; and (ii) heating the impregnated ZSM-5 or ZSM-11 or step (i) for at least one hour at a temperature of at least 150/sup 0/C.
