Gas separation methods have received much attention, as the process plays a key role in various industries. Among the gas separation methods, membrane-based methods, particularly those employing mixed matrix membranes (MMMs), are important. MMMs are formed by modifying the properties of polymeric membranes by fabricating them with inorganic particles. This paper presents the gas transport behaviour in MMMs fabricated with porous particles, as described by two-phase (ideal) and three-phase (non-ideal) models. The effect of particle porosity on gas permeability was incorporated into existing models through the J parameter, which adjusts the particle loading percentage. J-modified models were verified against existing models and experimental data for gas permeability were obtained with various MMMs. It was found that the proposed modified models provide a better prediction of the gas transport behaviour in MMMs.

“…[12][13][14] As can be seen in Figure 1, in the preliminary models, ideal and perfect surface contact between the polymer and the particle was assumed. This means, firstly, that researchers supposed that an ideal contact exists between polymer and particles, resulting from complete interface adhesion.…”

“…To validate the model outcomes, experimental results of gas permeation in Matrimid® 5218 Matrix embedding with micro‐sized nanoporous sodium zeolite‐Y (NaY zeolite) particles were employed . Additionally, to evaluate the particle size and loading effect on the permeability, results of mixed‐gas permeation for Matrimid® 5218‐based MMMs containing various particle fillers such as NaY, 5A, ZSM‐5, MIL‐53, TS1‐100, TS1‐25, and ETS‐10 were used to suitably compare the CO 2 /CH 4 permeability. To verify and evaluate the obtained results, the parametric analysis was performed for the MMMs model with porous fillers.…”

A new permeation model in porous filler–based mixed matrix membranes for CO₂ separation

In this paper, a novel comprehensive permeation model for mixed matrix membranes (MMMs) is introduced. This model shows the importance of understanding and developing a more reliable model for the permeation behavior of MMMs containing porous filler nanoparticles. A new method is established to provide a more precise/large‐scale three‐dimensional MMMs geometry. The required number of spherical porous fillers in random/nonuniform positions in the polymer matrix is calculated. Interfacial equilibrium constant (K) at the polymer/filler interfaces was adjusted as the concentration ratio of the diffusing penetrants (C2 and C1) at the interface, respectively. In this case, the K values are changed by varying the intended gaseous concentration due to their permeation through the MMM. Hence, its effect on penetrants effective diffusion coefficient was examined. Then, the obtained results were evaluated with similar experimental data, which showed much consistency. Therefore, the accurate calculation method for MMMs permeability was governed for the entire range of the operating pressures in MMMs. The results showed that the permeability of MMMs increases with increasing filler particle size. On the other hand, variations that occur in the MMM permeability at various particle size were much more distinct at higher loadings. Moreover, some well‐known analytical permeation models were used to compare and validate the model's permeability results. It can be concluded that this model provides a method for more precise and realistic design of MMMs as well as to better construe the large number of related experimental data. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

Composite layer containing postmodified MIL‐53 (P‐MIL‐53) was exploited to be coated on as‐fabricated asymmetric hollow fiber membrane for improving gas separation performance. The morphology and pore size distribution of P‐MIL‐53 particles were characterized by SEM and N2 adsorption isotherm. The EDX mapping and FTIR spectra were performed to confirm the presence of P‐MIL‐53 deposited on the outer surface of hollow fiber membranes. The results of pure gas permeation measurement indicated that incorporation of P‐MIL‐53 particles in coating layer could improve permeation properties of hollow fiber membranes. By varying coating times and P‐MIL‐53 content, the membrane coated with PDMS/15%P‐MIL‐53 composite by three times achieved best performance. Compared to pure PDMS coated membrane, CO2 permeance was enhanced from 29.96 GPU to 40.24 GPU and ideal selectivity of CO2/N2 and CO2/CH4 also increased from 23.28 and 26.95 to 28.08 and 32.03, respectively. The gas transport through composite membrane was governed by solution‐diffusion mechanism and CO2 preferential adsorption of P‐MIL‐53 contributed to considerable increase of CO2 solubility resulting in accelerated permeation rate. © 2017 Wiley Periodicals, Inc.
