Abstract	Metal–organic frameworks (MOFs) are considered since last decade as promising materials notably for the development of gas separation and purification by adsorption processes. Selectivity and working capacity are important parameters for adsorbent selection. Unfortunately, these parameters are mostly estimated from pure component isotherms without comparison with mixture experimental data because these measurements are time consuming and complicated. The aim of this study is to compare IAST mixture simulations from pure component isotherms with co-adsorption measurements considering promising industrial adsorption processes for a mesoporous MOF, MIL-100 (Fe). This adsorbent has a good selectivity for CO2 over permanent gases. Three adsorption processes have been studied (i) CO2 capture: a CO2/N2 separation by PSA or mixed membrane process, (ii) biogas and (iii) natural gas purification: a CO2/CH4 separation by PSA process. Pure component isotherms (CO2, CH4 and N2 at 303.15 K) and binary mixture equilibrium measurements (CO2/N2 at 1 and 4 bar and 303.15 K and CO2/CH4 at 303.15 K and 1 and 4 bar for biogas and 30 bar for natural gas) have been realized. A particular attention has been paid for the pure component representation in order to obtain IAST predictions as accurate as possible. The pressure ranges and the theoretical models are selected to get the best fitted curves of pure component adsorption measurements. In these conditions, the comparison between experimental and simulated values in terms of adsorbed quantities and selectivities allows us to conclude that in the case of mixtures studied in this work on MIL-100 (Fe), IAST is a suitable model for such applications.
