沸石分子筛,具有分子筛分作用和大的比表面等优异性能,因而在吸附、催化等方面的应用极为广泛,国内外都很重视这方面的研究。沸石具有夹杂或吸留寄生分子的作用,这种寄生分子的存在,将影响沸石的结晶性能、电化学性能和催化活性等,对它的深入研究,有利于改进沸石分子筛的合成和改性技术、提高其催化、吸附性能。关于气体分子在有效直径小于气体分子的沸石小笼里吸留的研究,还为气体分离和低压贮运开辟了新途径。因此关于分子筛的吸留作用的研究是令人感兴趣的。J.A.Rabo曾在第五届国际催化会议上提出专题论文;近年来,人们采用红外光谱,X射线衍射等 Zeolite molecular sieve has the excellent performance of molecular sieve and large specific surface. Therefore, it is widely used in the fields of adsorption and catalysis and so on. Both domestic and foreign researchers attach great importance to this research. Zeolite has the function of inclusion or occlusion of parasitic molecules. The existence of this kind of parasitic molecules will affect the crystallization, electrochemical and catalytic activity of zeolite, and further studies on it will help to improve the synthesis and modification of zeolite , Improve its catalytic, adsorption properties. Gas molecules in the effective diameter smaller than the gas molecules zeolite small cages research, but also for gas separation and low pressure storage opened up a new way. Therefore, the study on the occlusion of molecular sieve is of interest. J.A.Rabo had a monograph at the Fifth International Conference on Catalysis; in recent years, people using infrared spectroscopy, X-ray diffraction
