| 摘 要： | 采用智能重量分析技术（Intelligent-Gravimetric Analysis）研究了环戊烷在silicalite-1分子筛上的扩散性能。同一温度下，吸附质的扩散速率随其吸附量的增加而减小，而温度越高扩散系数越大。本文同时讨论了吸附质分子的分子构型、尺寸、吸附温度和吸附量等因素对吸附质扩散性能的影响。

| Abstract: | Diffusion of cyclopentane in silicalite-1 zeolite was investigated systematically using the intelligent gravimetric analysis technology (IGA). The results indicated that, diffusion rates of the sorbate decreased with increasing loading at the same temperature,but diffusion coefficients increased with increasing temperature. Simultaneously, the effects of the frame structure, the size of the sorbate molecular,and the temperature and loading on diffusion were investigated. |
