Isothermal Modeling of CO2 and H2S Adsorption Using Metal Organic Frameworks (MOFs)

Adsorption of gases is one of the important processes in the oil, gas, petrochemical industries and also environmental protection. In this research, modeling of carbon dioxide and hydrogen sulfide gases adsorption was investigated using metal organic frameworks to obtain adsorption system behavior and adsorption capacity prediction. Three parameters and multilayer isothermal models were used in the modeling. Experimental data of carbon dioxide and hydrogen sulfide adsorption on four metal organic frameworks were used to obtain the model parameters. The correlation coefficient was used to evaluate the models performance. The modeling results showed that the adsorption process of CO2 and H2S was physical and the adsorbents have best performance for carbon dioxide adsorption. Between multilayer models, BET model showed a good agreement with experimental data than other models.
