    • The present invention provides a method for preparing silica containing molecular sieves which may be mixed with an organic polymer to create a mixed matrix membrane. Further, this invention includes a method of making such a mixed matrix membrane and the membrane itself. A process for separating component gases from a mixture using the subject mixed matrix membrane is also described. The method for preparing silica containing molecular sieves comprises super water washing silica containing molecular sieves to produce water washed molecular sieves which are substantially free of surface remnants. Super water washing also ideally lowers the concentration of alkali metals in the molecular sieves. The water washed sieves are sufficiently free of surface remnants such that when the water washed sieves are subjected to a Sieve Wash Conductivity Test, a wash filtrate is produced having a conductivity of less than 110 micro mhos/cm, more preferably less than 80 micro mhos/cm, even more preferably less than 50 micro mhos/cm, and most preferably less than 30 micro mhos/cm. It is believed that super washing the sieves to this degree will enhance, compared to conventional preparation techniques, the ability of the molecular sieves to bond with an organic polymer to form a highly selective and permeable mixed matrix membrane.
    • 本发明提供了一种制备含二氧化硅的分子筛的方法,该方法可与有机聚合物混合以产生混合基质膜。 此外,本发明包括制造这种混合基质膜和膜本身的方法。 还描述了使用主题混合基质膜从混合物中分离组分气体的方法。 制备含二氧化硅的分子筛的方法包括含有分子筛的超级水洗二氧化硅,以产生基本上没有表面残留物的水洗分子筛。 超级水洗也有利于降低分子筛中碱金属的浓度。 水洗筛足够地没有表面残留物,使得当洗涤过的筛子进行筛洗电导率测试时,产生电导率小于110微摩尔/厘米,更优选小于80微摩尔的洗涤滤液 / cm,甚至更优选小于50微摩尔/厘米,最优选小于30微摩尔/厘米。 据认为,与常规制备技术相比,超级洗涤这种程度的筛子将增强分子筛与有机聚合物结合以形成高选择性和可渗透的混合基质膜的能力。
