| 摘 要： | 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. |
| 关 键 词： | SAPO-35 甲醇制烯烃 SAPO-34 积炭物种 失活 |

| Abstract: | SAPO-35 molecular sieve samples with different Si contents were hydrothermally synthesized using hexamethyleneimine as the template and characterized by XRD, XRF, SEM, MAS NMR, XPS and N2 physisorption. Three SAPO-35 samples were tested as methanol-to-olefins catalysts. After the reaction, the evolution of coke species was investigated over SAPO-35 and SAPO-34 catalysts with similar Si concentrations. A correlation between the cage size of the molecular sieves and the coke species was obtained. |
| Keywords: | SAPO-35 Methanol to olefins SAPO-34 Coke species Deactivation |
