| Outline of Final Research Achievements |
Prediction of adsorption equilibria of volatile organic compounds (VOCs, toluene, n-decane, n-hexane, acetone and methanol) on various adsorbents (activated carbon, zeolite, mesoporous silica and mesoporous carbon) under supercritical carbon dioxide conditions was investigated with a new methodology by using the non-ideal adsorbed solution theory (NIAST) coupled with the Dubinin & Astakhov (DA) equation. The proposed DA - NIAST model could provide accurate predictions of VOCs adsorption equilibria on the various adsorbents in comparison with the conventional methodology by using the ideal adsorbed solution theory (IAST).
