In this work, the separation characteristics of CO2 from CO2 and CH4 mixed gas was studied using pressure swingadsorption (PSA) process. Zeolite 13X was used as an adsorbent to adsorb CO2 from gaseous stream in a fixed-bed ofadsorbent. The adsorption experiments were performed with various gas flow rates, adsorption pressures and temperatures.The deactivation model was used to analyze the adsorption kinetics of CO2 using the experimental breakthrough data.From this work, it was found that the activation energies of adsorption and deactivation were 29.15 and 13.0 kJ/mol,respectively. And the experimental breakthrough curves were agree very well with the adsorption isotherm models basedon Freundlich equation.
