ABSTRACT:
Zeolite catalysts containing gallium, the gallium is primarily present in the framework of the catalyst and the catalyst contains little or no non-framework gallium; and methods for producing such catalysts by varying the reaction molar ratios of SiO.sub.2 /Ga.sub.2 O.sub.3 ; and the use of such catalysts to produce high octane aromatics.
