英文摘要Ammonium hexafluorosilicate (AHFS) is an effective dealumination reagent for MCM-22 zeolite, and the Si/Al(2) ratio range of MCM-22 was extended largely (SiO(2)/Al(2)O(3) similar to 300) by AHFS treatment. The physicochemical properties of the MCM-22 samples before and after dealumination were characterized by XRD, XRF, N(2) adsorption and pyridine-IR measurements. Also, the samples were used as catalysts in C(4) alkenes catalytic cracking to propene and the results showed that properly dealuminated MCM-22 (Si/ Al(2) ratio 58) exhibited higher activity, better stability and similar product distribution relative to the parent MCM-22 zeolite.
