| 摘 要： | 以磷酸、拟薄水铝石和硅溶胶为原料，三乙胺为模板剂，采用水热合成法合成Y／SAPO-5复合分子筛。利用XRD、FT—IR、SEM等手段对样品结构和形貌进行了表征，所合成的分子筛是Y型分子筛晶粒被SAPO-5分子筛晶粒包裹形成的10μm左右的球状双结构复合分子筛。采用催化甲醇脱水制备二甲醚的反应考察了复合分子筛的催化性能，结果表明，对于催化甲醇脱水制备二甲醚的反应所合成的复合分子筛在温度为463～523K时随温度升高甲醇转化率增大，且仍保持着较高的DME选择性。

| Abstract: | Binary structure zeolites Y/SAPO-5 were synthesized by hydrothermal synthesis method,with phosphoric acid,pseudoboehmite,and silica sol being used as phosphorus,aluminum,and silicon sources,respectively,and triethylamine as template.The samples obtained were characterized by means of XRD,FT-IR and SEM.The results indicate that the synthesized zeolite samples is the binary structural microspheres with NaY zeolites as core and SAPO-5 as shell about 10 μm.The catalytic performance was investigated by the synthesis of dimethyl ether from methanol.The experiments of the catalysis of dimethyl ether show that Y/SAPO-5 exhibited excellent selectivity of DME,with the increase of conversion of methanol over the temperature range 463~523 K. |
