| 摘 要： | 在SAPO-34分子筛合成的成核阶段进行微波干扰，成功合成出棱片状SAPO-34分子筛，通过XRD、BET、SEM及NH3-TPD手段对样品进行表征，并考察在甲醇转化制烯烃反应中的催化性能。结果表明，此方法合成的SAPO-34分子筛存在特殊的酸位中心分布以及特殊的形貌，在甲醇转化制烯烃反应中表现出更长的催化寿命，甲醇转化率接近100%，乙烯和丙烯总选择性超过85%。

| Abstract: | Lamellate SAPO-34 molecular sieves were synthesized successfully through microwave jamming at nucleation stage,and were characterized by XRD,BET,SEM and NH3-TPD.Their catalytic properties for methanol to olefin(MTO) reaction were assessed.The results indicated that the as-synthesized SAPO-34 molecular sieves had unique acid site distribution and morphology,which made the molecular sieves have relative longer life span in MTO reaction.Methanol conversion was almost 100% and the total selectivity to ethylene and propylene could be over 85%. |
