 The abstract states that benzene-based hypercross-linked polymers, HCP, can be used as an adsorbent material to increase carbon dioxide, CO2, uptake capability and selectivity. It also mentions that the HCP has a surface area of 806 square meters per G and a micropore volume of 453 square meters per G, while the modified HCP has a surface area of 0.19 cubic centimeters per G and a micropore volume of 0.14 cubic centimeters per G. The CO2 and nitrogen gas adsorption experiments are conducted at temperatures ranging from 298K to 328K and pressures up to 9 bar. The results show that the maximum CO2 adsorption capacity is 301.67 milligrams per G for HCP and 414.41 milligrams per G for the amine modified HCP. The CO2 adsorption thermodynamics are assessed by calculating the enthalpy change, minus 14.852 kilojoules per mole, entropy change, minus 0.024 KJ.
