氧和氮在炭分子筛上的吸附与扩散

Adsorption and Diffusion of Oxygen and Nitrogen in Carbon Molecular Sieve

用重量法研究了氧、氮在两种空分用炭分子筛上的吸附与扩散。结果表明,氧和氮在炭分子筛中的扩散是活化扩散,该过程可用双孔模型进行描述。求得了氧、氮的扩散系数。

The adsorption and diffusion of oxygen and nitrogen in two samples of carbon molecular sieve used for air separation have been studied by gravimetric method. The results indicate that the diffusion process of oxygen and nitrogen in carbon molecular sieve is activated, such an process may be represented by the dual diffusion resistance model. The micropore diffusiviites of oxygen and nitrogen are obtained.
