▎ 摘　　要

This study presents the adsorption performance indicator for the evaluation of thermal power plant CO2 capture on mesoporous graphene oxide/TiO2 nanocomposite. To begin, this adsorbent was synthesized and characterized using N-2 adsorption-desorption measurements (BET and BJH methods), X-Ray Difflaction (XRD), Field Emission Scanning Electron Microscopy (FE-SEND and FT-IR spectroscopy. Subsequently, the pure single-component adsorption isotherms measured at 298 K and the Ideal Adsorbed Solution Theory (LAST) solved with direct search minimisation were applied to estimate the selectivity of the synthesized mesoporous graphene oxide/TiO2 nanocomposite for CO2 over N-2 and predict CO2 adsorption capacity in the CO2:N-2 binary gas mixtures, including the molar ratio of 5:95, 10:90 and 15:85. Finally, the results validated by the breakthrough experiments at a fixed-bed column were applied to estimate the Adsorption Performance Indicator (API) for the evaluation of CO2 separation from N-2 in the Pressure Swing Adsorption (PSA) process with respect to different types of thermal power plants.
