A facile way to synthesize a series of SAPO-34 zeolites was developed by using the mixed templates of morpholine and TEAOH with changing the temperature. Among these samples, SAPO-34-210 exhibited with the longest lifetime and the highest selectivity to light olefin for methanol to olefin (MTO) reaction. The characterizations suggested that SAPO-34-210 has unique Si distribution due to much more amount of TEAOH introduced into structure, which resulted in the excellent catalytic performance.

通过控制水热温度合成的SAPO-34具有优异的甲醇制烯烃催化性能

通过使用吗啉和TEAOH的混合模板随温度变化，开发了一种简便的合成一系列SAPO-34沸石的方法。在这些样品中，SAPO-34-210表现出最长的寿命和对甲醇到烯烃（MTO）反应的对轻烯烃的最高选择性。表征表明，由于引入结构中的TEAOH的数量更多，SAPO-34-210具有独特的Si分布，这导致了出色的催化性能。
