CO₂, N₂, and H₂ Adsorption by Hyper-Cross-Linked Polymers and Their Selectivity Evaluation by Gas–Solid Equilibrium

In this study, the effect of hyper-cross-linked adsorbent structural parameters on gas adsorption and selectivity was investigated. Hyper-cross-linked polymere (HCP) adsorbents were synthesized based on three widely used monomers, such as benzene, polystyrene, and carbazole. Cross-linker value and synthesis time were considered as structural parameters. The selectivities of CO2/N2 and CO2/H2 at 1 bar and 298 K were evaluated by the ideal...
