%X The adsorption equilibria of pure supercritical N 2 and CO 2 on the activated carbon Yigao-A and carbon molecular sieve CMS-200 were measured by the gravimetric method (IGA-001, Hiden) in the temperature region of 313.15-393.15 K and pressure region of 0-2 MPa. The adsorption kinetics of N 2 and of CO 2 on the activated carbon Yigao-A and carbon molecular sieve CMS-200 at 313.15 K in 50 kPa were tested. The Langmuir-Freundlich model was applied to analyze the adsorption isotherms. The adsorption kinetics was investigated with the Fickian model. The analysis of adsorption equilibria showed that a high temperature, low pressure is beneficial to the equilibria based selective adsorption of supercritical CO 2 on the activated carbon Yigao-A and carbon molecular sieve CMS-200. The investigation of adsorption kinetics exposed that the carbon molecular sieve CMS-200 is able to separate CO 2 from the N 2/CO 2 mixture by its kinetic effect, and lower temperature is preferred.
