Adsorption Evaluation With Zeolites For Gases In The Confined Space

The high humidity characteristics of the confined space challenge the zeolites with good water performance. In this study, the adsorption of N-2 , CO2, H-2, CH4, CO and H2O vapor by zeolites (5A and 13X) were discussed, and the structure of zeolites were characterized by XRD, FTIR and SEM. The adsorption breakthrough curve of CO2 was measured by the fixed bed reactor, and the adsorption characteristics were obtained under different temperatures and gas velocities. The results showed that 13X-2 zeolite had the CO2 adsorption capacity of 100.1 cm(3) :g(-1), which is higher than the others, and the appropriate water stability.
