dc.description.abstractThe adsorption equilibrium and kinetics of CO2,CH4, and N2 on three types of BETA zeolites were investigated at different temperatures and a defined partial pressure range from dynamic breakthrough experiments. The adsorbed amount followed the decreasing order of CO2>CH4>N2 for all studied materials. For the same ratio of SiO2/Al2O3, the Na-BETA-25 zeolite showed a higher uptake capacity than H-BETA-25, due to the presence of a Na+cationic center. Comparing the same H+compensation cation, zeolite H-BETA-25 expressed a slightly higher adsorption capacity than H-BETA-150. Regarding the selectivity of gases, based on their affinity constants, H-BETA-150 displayed the best ability. The adsorption kinetics was considered using the zero-length-column (ZLC) technique.pt_PT
