| 英文摘要 | mcm-22 zeolites with high sio(2)/al(2)o(3) (si/al(2)) ratios were synthesized by a one-pot procedure with the assisting of boron. based on this boron-containing method, the si/al(2) ratios of the mcm-22 zeolites could be greatly extended from 30 to 600 in control by tuning the si/al(2) ratios of the starting gels. icp-aes and (11)b mas nmr results demonstrated that a small part of the boron still existed in the framework of the mcm-22 after calcination and ammonium exchange. however, the residual boron species had little influence on the physicochemical properties of the mcm-22 samples evidenced by xrd, bet. tg-dta, nh(3)-tpd, and py-ir determinations. the reaction of catalytic cracking of i-butene to propene was carried out to study the performances of the high silica mcm-22 catalysts. increasing of the si/al(2) ratios in the mcm-22 zeolites suppressed the formation of byproducts such as propane and aromatics effectively, and the optimal selectivity towards propene was obtained on the sample with a si/al(2) ratio of 158.
