Adsorption of CO2 on Molecular Sieves and Activated Carbon
Volumetric adsorption studies of CO 2, N 2, or H 2 on molecular sieve 13X, molecular sieve 4A, and activated carbon were conducted at 25 °C up to a pressure of 300 psi (∼2× 106 Pa). Preferential adsorption of CO 2 was observed with all three sorbents. The adsorption capacity of CO 2 for molecular sieve 13X was higher than that for molecular ...
