摘要：

In this paper, the equilibrium modeling of CO2 adsorption on the new adsorbent (composite of UiO-66 and graphene oxide) which has previously been reported in the experimental study has been investigated. For this purpose, in the first step, six adsorption isotherm models, including the Langmuir, Freundlich, BET, Toth, Dubinin-Astakhov and Maxwell-Stefan model coupled with vacancy solution theory (VST) have been used to fit the pressure dependent CO2 adsorption on the composite which has had the maximum CO2 uptake capacity (UiO-66/GO-5 composite) reported in the previous experimental study. Furthermore, Henry's law constant for evaluating adsorption affinity of CO2 on this composite has been estimated by the Virial model. In the second step, the ideal adsorbed solution theory (IAST) solved with direct search minimisation has been used to predict the adsorption equilibrium of CO2/N-2 binary gas mixture on UiO-66/GO-5 composite.
