讨论了气体分离用炭膜平均孔径对膜分离特性的影响。可以看出，决定透过膜传质机理的平均孔径，是膜分离特性的决定性影响因素。对于Ｎ２／Ｏ２分离而言。当控制机理处于Ｋｎｕｄｓｅｎ扩散和分子筛分之间的过渡区域时，存在着对应于最大分离能力和无选择性的两个特征孔径。
The influence of the average pore size of carbon membrane for gas separation on the membrane separation characteristics was discussed. It can be seen that the average pore size that determines the mechanism of mass transfer through the membrane is a decisive factor in membrane separation characteristics. For N2 / O2 separation. When the control mechanism is in the transition region between Knudsen diffusion and molecular sieve, there are two characteristic apertures corresponding to maximum separation capacity and no selectivity.
