Claim 14:
15. A process of forming a catalyst for aromatizing hydrocarbons, the process comprising:
enhancing a mesoporosity of a zeolite support by a base-leaching treatment, an acid-leaching treatment, or both to form a zeolite support having enhanced mesoporosity;
mixing the zeolite support having enhanced mesoporosity with a solution containing zinc or gallium to disperse the zinc or gallium on the zeolite support having enhanced mesoporosity; and;
calcining the zeolite support having enhanced mesoporosity with zinc or gallium dispersed thereon to form a zinc- or gallium-doped zeolite catalyst having a mesopore volume of greater than 0.09 cm3/g and less than 0.20 cm3/g;
wherein the zinc- or gallium-doped zeolite catalyst has an average pore size of from 6 nm to 14 nm and;
wherein the zinc- or gallium-doped zeolite catalyst comprises from 1 wt. % to 30 wt. % zinc and/or gallium dopant.
