Carbon molecular sieve (CMS), a porous material, can selectively adsorb specific gas molecules due to its micropore structure different from that of conventional activated carbon. However, in order to obtain a desired gas with high purity, it is still necessary to develop an economical method for synthesizing CMS having a pore structure suitable for a specific molecule. The goal of this study is to develop a facile CMS synthesis method which is applied to pressure swing adsorption (PSA) for CO2 separation. In this study, CMS was synthesized using a simple method of impregnating activated carbon with a prepolymer of resorcinol resin, polymerizing it on the surface, and then heat-treating it. And the pore structure and physical properties according to the synthetic conditions were characterized and the CO2 adsorption capacity was evaluated. It was found that the CMS prepared in this study has the feasibility for efficient CO2 separation in practical applications. |
