Abstract
An aromatization catalyst is obtained by physical mixing of a pentasil type zeolite, for example H-ZSM-5 and a zinc oxide-alumina co-precipitate. The weight ratio of the zeolite to the co-precipitate ranges from 4.3 to 28.3. The Zn/Al atomic ratio in the co-precipitate may range from about 0.16 to 25.0. The composite catalyst yields greater amounts of aromatics, particularly BTX aromatics, when contacted with an olefinic and/or paraffinic feedstock than the respective zeolite alone.
