英文摘要MCM-22 precursor with various SiO2/Al2O3 molar ratios was treated by vapor-phase silylation. MCM-22 zeolite and its products of vapor-phase silylation were characterized by X-ray diffraction, solid state nuclear magnetic resonance, N-2 adsorption-desorption, and toluene adsorption techniques. The results showed that Si(OH)(2) pillaring structure was formed in the interlayer of MCM-22 with SiO2/Al2O3 molar ratios of 50-100 without extraction of framework aluminum through vapor-phase silylation, resulting in the expansion of interlayer distance and the increase of micropore volume. The N-2 adsorption-desorption isotherms of MCM-22 zeolite before and after silylation were analyzed by the density functional theory, and the specific surface area and pore volume of 10 member ring (10 MR) rnicropores and those of the supercage system were successfully obtained. As a result of vapor-phase silylation, the specific surface area and pore volume of the supercage system increased, while those of 10 MR micropores decreased. The equilibrium adsorption amount of toluene over MCM-22 zeolite with various SiO2/Al2O3 molar ratios was enhanced after vapor-phase silylation.
