“…In general, these membranes have good selectivity but low permeability. Porous membranes are so similar to the common lters from the function and structure viewpoints [12,13]. The structure of these membranes is hard and made up of pores that have heterogeneous diffusion.…”

“…These days, membrane technologies have vastly come into consideration for several reasons such as low energy consumption, the low volume of modules, the possibility and availability, without thermal sensitivity, the very negligible pressure drop, low energy loss and low investment costs in comparison with other separation methods [1][2][3][4][5][6]. Regardless of the fact that membrane technologies have remarkable advantages in comparison with other separation methods, membrane processes are mainly dealt with several problems such as concentration polarization, blockage, not predicting the proper behavior of the membrane, stability, incomplete separation, puri cation and low permeability [7][8][9][10][11][12][13].…”

In this research, the effect of adding MIL-100 (Fe) MOFs on the PEBAX membranes has been scrutinized in two grades of 1657 and 2533. Initially, the intended membranes were synthesized by the solutioncasting method. Then, the XRD and SEM were applied to deliberate the in uence of adding to the structure of both types of membranes. In consequence, the separation function of the pair gases of CO 2 /CH 4 CO 2 /N 2 and CO 2 /O 2 and their permeability were considered at the pressure of 3.5 bar and temperature of 25°C. Eventually, their function was compared by Robeson diagrams of 1991 and 2008. The comparison results by Robeson diagrams indicated that the PEBAX1657/MIL-100 (Fe) and PEBAX2533/MIL-100 (Fe) membranes containing 5 wt.% of MOF represent more suitable performance in separating CO 2 /CH 4 in comparison with the axis of the Robeson diagram. However, their function for separating the aforementioned gases requires more modi cations.

Initially, the intended membranes were synthesized by the solution-casting method. Then, the XRD and SEM were applied to deliberate the influence of adding MIL-100 (Fe) to the structure of both types of membranes. In consequence, the separation function of the pair gases of CO2/CH4، CO2/N2 and CO2/O2 and their permeability were considered at the pressure of 3.5 bar and temperature of 25°C. Eventually, their function was compared by Robeson diagrams of 1991 and 2008. The comparison results by Robeson diagrams indicated that the PEBAX1657/MIL-100 (Fe) and PEBAX2533/MIL-100 (Fe) membranes containing 5 wt.% of MOF represent more suitable performance in separating CO2/CH4 in comparison with the axis of the Robeson diagram.
