Abstract

The present invention relates to a process for preparing a catalyst for alkane aromatization providing high % conversion, high yield, high selectivity of aromatics, and high selectivity of p-xylene in xylene, wherein said process comprises the following steps: (a) contacting a zeolite with a solution of group IIIA metal salt; (b) contacting the zeolite obtained from step (a) with the solution of metal salt selected from a group VIIB metal, a group VB metal, or a mixture thereof; and (c) contacting the zeolite obtained from step (b) with alkoxysilane, characterized in that the solution of salt in step (b) comprising a glycol solvent as a reducing agent under a basic condition, and step (b) is operated at the temperature higher than 120 ?C.
