Our Gibbs ensemble Monte Carlo simulations investigated the adsorption separation of three binary gas mixtures in slit pores: CH4/CO, C2F6/N2, and SO2/CO2. CH4/CO showed low selectivity, while C2F6/N2 demonstrated high selectivity, and SO2/CO2 fell between. Selectivity trends for CH4/CO and C2F6/N2 revealed monolayer and bilayer adsorption with varying pore widths. SO2/CO2 showed a complex 3-layer adsorption mechanism. A broader analysis of 276 mixtures showed that higher ratios of critical temperatures between components increased selectivity, simplifying separation. A linear relationship between selectivity and adsorption heat ratios at low pressures was also identified. These findings are key for developing efficient gas separation materials for natural gas purification and carbon capture, supporting sustainable energy solutions.
