以六亚甲基亚胺为模板剂,采用水热法合成了不同硅含量的磷酸硅铝分子筛SAPO-35,并利用X射线衍射、X射线荧光光谱、扫描电镜、固体核磁、X射线光电子能谱和N2吸附-脱附等方法对样品进行了表征.研究了不同硅含量的SAPO-35分子筛在甲醇转化制烯烃反应中的催化行为,同时对比分析了具有相近硅含量的SAPO-35和SAPO-34分子筛在甲醇转化反应过程中积炭物种随反应时间的演变特征,尝试将分子筛结构和其积炭失活行为进行了关联. Using hexamethyleneimine as templating agent, SAPO-35 with different silicon content was synthesized by hydrothermal method and characterized by X-ray diffraction, X-ray fluorescence spectroscopy, scanning electron microscopy, solid state nuclear magnetic resonance, X-ray photoelectron energy Spectrum and N2 adsorption-desorption were used to characterize the samples.The catalytic behavior of SAPO-35 molecular sieves with different silicon contents in the conversion of methanol to olefins was studied. Meanwhile, the contents of SAPO-35 and SAPO with similar silicon contents -34 molecular sieve in the process of methanol conversion reaction of carbonaceous species evolved with the reaction time characteristics of attempts to molecular sieve structure and its coke inactivation behavior were related.
