| 摘 要： | 简述了沸石分子筛的结构组成，介绍了分子筛的性能。综述了物质在沸石分子筛中吸附与扩散的表现，列举了主要分子筛吸附性能与扩散系数的测量方法，介绍了不同类型分子筛的吸附扩散。在目前的研究中，每种测定沸石分子筛吸附性能的方法都有一定的适用条件，每种测定分子筛扩散系数的方法由于测量机理、边界条件与假设条件的不同，所得的扩散系数也有差异，要根据实际实验情况来选择适当的测量方法，不同分子筛适宜吸附的底物也不同，具有不同的应用价值。

| Abstract: | The paper introduces the structure and composition of zeolite molecular sieves, and it elaborates the property of zeolite molecular sieves. In this paper, the performance of the adsorption and diffusion of substances in zeolite molecular sieves is reviewed, and the paper lists the main methods of measuring the performance of molecular sieve's adsorption and diffusion coefficients. It also introduces the adsorption and diffusion of different types of molecular sieves. In the present study, each method of measuring the adsorption performance of zeolite molecular sieves has certain applicable conditions. Due to the difference of measurement mechanism, boundary conditions and assumptions, the diffusion coefficients obtained by different methods are also different. Therefore, the appropriate measurement method will be selected according to the actual experimental situation. As different molecular sieves have different substrates suitable for adsorption, it has different application values. |
