Claim 9:
10. The process of claim 1, where the hierarchical mesoporous ZSM-5 zeolite is prepared by a method comprising:
providing a starting ZSM-5 zeolite;
disintegrating at least a portion of the ZSM-5 zeolite in a first mixture comprising the starting ZSM-5 zeolite, sodium hydroxide, and a surfactant at a temperature of 100° C. for a first time period;
after the disintegrating the at least a portion of the ZSM-5 zeolite, recrystallizing zeolite constituents in the presence of the surfactant to produce a recrystallized ZSM-5 zeolite;
recovering the recrystallized ZSM-5 zeolite; and
calcining the recrystallized ZSM-5 zeolite, where the calcining removes the surfactant from the recrystallized ZSM-5 zeolite to produce the hierarchical mesoporous ZSM-5 zeolite having a hierarchical pore structure.
