| 摘 要： | 磷酸硅铝分子筛（SAPO）是由SiO2、AlO2^-、PO2^＋三种四面体单元构成的微孔型晶体，具有从六元环至十二元环的孔道结构，孔径在0．3nm～0．8mm，骨架呈负电性，具有可交换的阳离子，被广泛用作吸附剂、催化剂和催化剂载体，是一种具有优异择形选择性、热稳定性和湿热稳定性的新型催化材料。SAPO分子筛可呈现出由中强酸到强酸的催化性能，几乎可用于所有的烃类反应。

| Abstract: | Silicon aluminum phosphate (SAPO) molecular sieves are microporous crystals with the structure of SiO_2AlO~-_2PO~+_2 tetrahedral units. SAPO have electronegative framework and exchangeable cation and Lewis acidity. SAPO is a novel class of catalytic materials which exhibit excellent shape selectivity, thermal stability and hydrothermal stability,which can catalyze hydrocarbon reactions. |
