| 摘 要： | 介绍了硅，钛取代A1PO-11分子筛SAPO-11、TAPO-11的合成方法，采用X射线衍射（XRD）、扫描电子显微镜（SEM）、热重-差热、氮气吸脱附等手段对合成的分子筛进行了表征，考察了晶化温度和原料比对分子筛合成的影响。结果表明，硅，钛取代A1PO-11分子筛能生成AEL结构的TAPO-11分子筛；SAPO-11与A1PO-11分子筛表观形貌相差不大，而TAPO-11分子筛表观形貌则与A1PO-11分子筛有很大不同；硅，钛取代后分子筛的孔道半径及其孔容有所改变；3种分子筛都具有较好的热稳定性。 |

| Abstract: | The synthesis methods of AlPO-11,SAPO-11 and TAPO-11 molecular sieves substituted by Si or Ti were proposed.The molecular sieves were characterized by the techniques of X-ray diffraction(XRD),scanning electron microscopy(SEM),thermo-gravimetric/differential thermal analysis(TG/DTA) and N_2-adsorption.The effects of ratio of Si/Al,Ti/Al and crystallization temperature on synthesis of molecular sieves were discussed.The XRD results show that SAPO and TAPO molecular sieves with AEL structure can be obtained.The SEM results show that there is a great difference between the shapes of AlPO-11 and TAPO-11,and no great difference between the shapes of AlPO-11 and SAPO-11.The BET results show that the pore diameters and pore volumes are influenced by the incorporation of Si or Ti.It also shows that AlPO-11,SAPO-11 and TAPO-11 molecular sieves have good thermal stability. |
