Description
Summary:<abstract language="eng">This paper describes the separation of CO2 from a gas mixture containing 25% CO2, 4% O2 and 71% N2 using the pressure swing adsorption (PSA) technique. The adsorbent selected was the zeolite 13X due to its great adsorption capacity for CO2 and selectivity towards the other components of the gas mixture. The experimental technique was designed to identify the most important variables for the process and to optimize it. It is shown that the PSA technique can be used to separate CO2 from O2 and N2 to obtain an effluent containing 2% CO2 with 99% separation efficiency.
