The CO2 capture from gas mixtures is of great importance in the industry in terms of improving the quality of natural gas. Proficient adsorbents should reveal high CO2 capacity and also high CO2 selectivity. The adsorption capacity of TiVONT was investigated by Monte Carlo simulation in temperature and pressure ranges of 175–350 K and 0.5−50 MPa. CO2 adsorption of TiVONT was higher than CH4 at all pressures and temperatures. Isotherms and density profiles indicated that the nanotube was saturated at pressures larger than about 5 MPa. CO2 capacities of the nanotube were 44.76%, 46.73%, and 52.85% at about 5 MPa and, 175, 275, and 298 K, respectively. It was indicated that the highest CO2 selectivity in CO2/CH4 mixture occurred at 5 MPa as well as the composition of 60% CO2. Therefore, under these conditions, TiVONT can be considered as an effective adsorbent for adsorption and separation of CO2 to enhance natural gas mixture. [ABSTRACT FROM AUTHOR] |
