Abstract
Based on the theory of volume filling of micropores, an analysis of the structural and energy characteristics of model carbon adsorbents for the sorption of xenon and krypton from the depleted gas–air streams was carried out. It was found that the maximum adsorption capacity for Xe and Kr was achieved at a pore size ranging from ~0.8 to 0.9 nm. The adsorption of Хе, Kr, N2, and О2 onto T-3 activated carbon with the effective width of micropores of 0.94 nm was investigated at pressures up to 100 kPa and at a temperature of 293 K. It was shown that such an adsorbent can be effectively used to capture Xe and Kr from depleted gas–air streams.
