“…Therefore, the region of optimal membrane properties for the separation of CO 2 from flue gas identified by Merkel et al [69] can be amply reached with any of the MMMs prepared in this work (10-40 wt% ZIF-94 loading).

A R T I C L E I N F O Keywords:Metal organic frameworks ZIF-94 Mixed matrix membrane CO 2 capture A B S T R A C T Carbon capture and storage (CCS) using membranes for the separation of CO 2 holds great promise for the reduction of atmospheric CO 2 emissions from fuel combustion and industrial processes. Among the different process outlines, post-combustion CO 2 capture could be easily implemented in existing power plants. However, for this technology to become viable, new membrane materials have to be developed. In this article we present the development of high performance mixed matrix membranes (MMMs) composed of ZIF-94 filler and 6FDA-DAM polymer matrix. The CO 2 /N 2 separation performance was evaluated by mixed gas tests (15CO 2 :85N 2 ) at 25°C and 1-4 bar transmembrane pressure difference. The CO 2 membrane permeability was increased by the addition of the ZIF-94 particles, maintaining a constant CO 2 /N 2 selectivity of~22. The largest increase in CO 2 permeability of~200% was observed for 40 wt% ZIF-94 loading, reaching the highest permeability (2310 Barrer) at similar selectivity among 6FDA-DAM MMMs reported in literature. For the first time, the ZIF-94 metal organic framework crystals with particle size smaller than 500 nm were synthesized using nonhazardous solvent (tetrahydrofuran and methanol) instead of dimethylformamide (DMF) in a scalable process. Membranes were characterized by three non-invasive image techniques, i.e. SEM, AFM and nanoscale infrared imaging by scattering-type scanning near-field optical microscopy (s-SNOM). The combination of these techniques demonstrates a very good dispersion and interaction of the filler in the polymer layer, even at very high loadings.

“…A few experiments carried out in the last two years showed that it is relatively straightforward to fabricate high quality polymer/MOF composite membranes. [46][47][48] A recent study 49 showed that an approach based on the combination of atomically detailed simulations and continuum modeling can be used to predict the performance of composite membranes with MOFs. The same modeling approach was used in this study to examine how the performance of various polymeric membranes for CH 4 /H 2 separations can be enhanced by using Zn(bdc)(ted) 0.5 as filler particles to make composite membranes.…”

Grand canonical Monte Carlo and equilibrium molecular dynamics simulations have been used to compute adsorption isotherms and self-diffusivities of CH 4 /H 2 mixtures in a nanoporous metal organic framework, Zn(bdc)(ted) 0.5 , at room temperature for various compositions. Adsorption-based selectivity, ideal selectivity, and mixture selectivity of Zn(bdc)(ted) 0.5 membranes for separation of CH 4 /H 2 mixtures are predicted and compared. Performance of several composite membranes including Zn(bdc)(ted) 0.5 as filler particles in polymer matrixes is examined for separation of H 2 from CH 4 using a combination of atomistic and continuum modeling. Results show that Zn(bdc)(ted) 0.5 exhibits higher adsorption-based selectivity and mixture selectivity for CH 4 compared to widely studied isoreticular metal organic frameworks. Predictions of permeation models showed that using Zn(bdc)(ted) 0.5 in high-performance composite membranes as filler particles greatly enhances permeability of H 2 compared to pure polymeric membranes without lowering the selectivity. Even a small volume fraction of Zn(bdc)(ted) 0.5 is enough to carry the composite membranes made of polymers and this metal organic framework (MOF) above the current upper bound established for available polymeric membranes.

Origins and Evolution of Inorganic-Based and MOF-Based Mixed-Matrix Membranes for Gas Separations

Abstract:Gas separation for industrial, energy, and environmental applications requires low energy consumption and small footprint technology to minimize operating and capital costs for the processing of large volumes of gases. Among the separation methods currently being used, like distillation, amine scrubbing, and pressure and temperature swing adsorption, membrane-based gas separation has the potential to meet these demands. The key component, the membrane, must then be engineered to allow for high gas flux, high selectivity, and chemical and mechanical stability at the operating conditions of feed composition, pressure, and temperature. Among the new type of membranes studied that show promising results are the inorganic-based and the metal-organic framework-based mixed-matrix membranes (MOF-MMMs). A MOF is a unique material that offers the possibility of tuning the porosity of a membrane by introducing diffusional channels and forming a compatible interface with the polymer. This review details the origins of these membranes and their evolution since the first inorganic/polymer and MOF/polymer MMMs were reported in the open literature. The most significant advancements made in terms of materials, properties, and testing conditions are described in a chronological fashion.
