Abstract: Mesoporous ZSM-12 zeolite was prepared by desilication treatment in alkaline medium. The ZSM-12 samples before and after alkaline treatment were characterized by X-ray diffraction, N2 adsorption, solid state NMR, and NH3 temperature-programmed desorption. The effects of desilication on the structure, acidity, and catalytic performance of ZSM-12 zeolite in the alkylation of naphthalene were investigated. The results showed that the mesopore distribution can be controlled by changing the NaOH solution concentration without destroying the micropore framework of ZSM-12 zeolite. The mesopore volume was increased and pore size distribution was widened with increasing NaOH concentration. Furthermore, the additional mesopores generated by desilication acted as transferring channels, which improved the diffusion of the reactants and products. Therefore, the catalytic performance was effectively improved, and the conversion of naphthalene and the selectivity for 2,6-DMN were increased.
