英文摘要	sapo-34s with low and high si content were synthesized and characterized by xrd, xrf, nmr, ftir and tg-dsc. different si content generated no apparent difference in xrd patterns and p-31 and al-27 mas nmr spectra. the si coordination states studied by si-29 mas nmr predicted the acidity difference caused by si incorporation. the absorbance of bridge hydroxyls in ftir spectra also showed the amount of active sites differed with si content. both of the two samples were employed as catalysts in the transformation of chloromethane to light olefins and proved to be very selective catalysts for light olefins production. the influences of si content on chloromethane conversion and product selectivity were investigated in details. coke amount and coke species were determined by tg-dsc and ftir. coke formation was related to the si content of sapo-34 and corresponded to the catalytic performance.
