在无氟水热条件下合成了高硅CHA型铝硅酸盐（Si/Al摩尔比>100），晶种辅助老化处理对晶化起重要作用。这些铝硅酸盐在甲醇制烯烃反应中表现出长的催化寿命和对低级烯烃的高选择性。
High-silica CHA-type aluminosilicates (Si/Al molar ratio >100) were synthesized hydrothermally in the absence of fluoride media, where the seed-assisted aging treatment played an important role on the crystallization. These aluminosilicates showed a long catalytic lifetime with high selectivity toward lower olefins in the methanol-to-olefins reaction.
