Abstract: A process for preparing a hierarchical zeolite catalyst for aromatization of C5-C9 alkane that provides high conversion percentage of precursor to yields and high aromatics selectivity, wherein said process comprises the following steps: (a) preparing a solution containing alumina compound, silica compound, and soft template; (b) subjecting the mixture obtained from step (a) to hydrothermal process at determined time and temperature to form said mixture into the hierarchical zeolite; (c) contacting the hierarchical zeolite obtained from step (b) with ammonium salt solution; and (d) contacting the hierarchical zeolite obtained from step (c) with gallium salt solution; wherein the soft template in step (a) is a quaternary phosphonium salt in which the mole ratio of the silica compound to the alumina compound in step (a) is in a range of 20 to 120 and the gallium salt in step (d) has gallium to zeolite ratio in a range of 0.5 to 5% by weight.
