摘　　要：合成了具有CHA结构的SAPO-34和具有金属杂原子的MeAPSO-34（Me=Mn，Co和Mg）分子筛。采用XRD、XRF和NMR等方法表征了杂原子引入对合成产物的晶体结构、元素组成和骨架配位的影响。合成的分子筛除去模板剂后用于氯甲烷转化制备低碳烯烃的反应，结果发现，杂原子引入的修饰作用对反应的稳定性和产物分布具有重要影响。SAPO-34 and metal substituted SAPO-34 （Me= Mn, Co和 Mg） with CHA topological structure were synthesized. Their crystalline, chemical composition and framework element coordination states were characterized by XRD, XRF and NMR. These synthesized samples were employed as the catalyst for the reaction of chloromethane transformation to light olefins. Metal incorporation could improve the catalyst life and modify the product distribution.
