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.
