Adsorption of CO2, CH4 and N2 has been investigated using amine functionalized polymeric resins having diethanolamine, imidazole, dimethylamine and N-methyl piperazine covalently attached to the styrene-divinyl benzene copolymer (PS) matrix. The equilibrium adsorption of CO2, CH4 and N2 was examined on these functionalized polymers at pressures from atmospheric to 40 atm for CO2 and N2 while up to 10 atm for CH4 at 303K. PS-Imidazole showed the highest adsorption capacity for CO2 as compared to other functionalized polymers. No significant uptake of CH4 and N2 was observed at low pressures by any of the functionalized polymers. The adsorption isotherms were analyzed using dual mode sorption model and Ideal Adsorbed Solution Theory (IAST).
