一、前言沸石分子筛是具有均匀晶内孔道的结晶硅铝酸盐,孔道直径4～10?.已发现的天然沸石有三十多种,它们的摩尔硅铝比低于 10.人工合成沸石的研究工作自四十年代末期开展以来到1972年前合成的94种沸石中,72种合成于单纯无机硅铝酸盐系统,仅22种合成于含有机碱的硅铝酸盐系统.这些沸石大多硅铝比较低,仅14种硅铝比高于10.由

First, the forerunner Zeolite molecular sieve is a crystalline aluminosilicate with uniform intracrystalline channels, pore diameter 4 ~ 10 ?. Natural zeolite has been found in more than 30 kinds of their molar ratio of Si-Al less than 10. Synthetic zeolite Of the 94 zeolites synthesized from 1972 to 1972 since the late 1940s, 72 have been synthesized in purely inorganic aluminosilicate systems and only 22 have been synthesized in organic-based aluminosilicate systems. Most of these zeolites have been synthesized Si-Al is relatively low, only 14 kinds of Si-Al ratio higher than 10. From
