Abstract
One of the most famous porous adsorbents used for separation and storage of hydrogen is metal organic framework (MOF). In this study, the experimental data related to hydrogen adsorption on and desorption from five adsorbents including MOF-5, MOF-177, MOF-200, MOF-205 and MOF-210 is adopted. Then, the hydrogen sorption is modeled by applying Sanchez–Lacombe Equation of State (SL EoS). The amount of hydrogen uptake in the adsorbents is obtained through hydrogen-adsorbents phase equilibrium calculations at temperature 77 K and various pressures up to 80 × 105 Pa. The result is compared with the experimental data to show the precision of SL equation of state in predicting the hydrogen sorption trend. SL EoS predicts the experimental results satisfactorily, even though in comparison with PHSC EoS, the latter shows a little reduction in average absolute deviation.
