A hierarchically porous zeolite ZSM-5 is prepared under hydrothermal conditions by using hexadecyltrimethoxysilane as inhibitor and template. The physical and acid properties of the hierarchically porous ZSM-5 are characterized by XRD, SEM, N2 physisorption and NH3-TPD techniques. Benzene alkylation with methanol is carried out with both conventional and hierarchically porous ZSM-5 in a fixed bed reactor. The creation of mesoporosity in zeolite ZSM-5 promotes benzene conversion and xylene selectivity with respect to conventional counterpart.
