“…Nanocrystal HKUST-1 was incorporated into two glassy polymers, namely ODPA-TMPDA and 6FDA-TMPDA (The abbreviations of these polymers will be explained in Section 2.1). These polymers were selected for its higher C 2 H 4 permeability as compared to commercially available glassy polymers (e.g., Matrimid ® , polysulfone, and Ultem ® /P84) [32,33,51,52]. Our results showed that, with the addition of HKUST-1 nanocrystals, a clear improvement in C 2 H 4 permeability of the membranes can be observed.…”

“…Apart from this, inorganic membranes, such as those based on pure zeolites and metal-organic frameworks (MOFs), are typically high-performing but hampered by their poor scalability potential [30]. Beyond membrane performances, other real-life challenges, such as effects of high temperatures and pressures, presence of moisture in the feed gas and impurities such as H 2 S that are damaging to the membranes, must be addressed to realize industrial applications [31][32][33][34][35][36][37]. However, in this work, our aim is to develop mixed-matrix membranes, which amalgamate the merits of both polymeric and inorganic membranes, to achieve enhanced C 2 H 4 /C 2 H 6 separation.…”

Leveraging Nanocrystal HKUST-1 in Mixed-Matrix Membranes for Ethylene/Ethane Separation

The energy-intensive ethylene/ethane separation process is a key challenge to the petrochemical industry. HKUST-1, a metal–organic framework (MOF) which possesses high accessible surface area and porosity, is utilized in mixed-matrix membrane fabrication to investigate its potential for improving the performance for C2H4/C2H6 separation. Prior to membrane fabrication and gas permeation analysis, nanocrystal HKUST-1 was first synthesized. This step is critical in order to ensure that defect-free mixed-matrix membranes can be formed. Then, polyimide-based polymers, ODPA-TMPDA and 6FDA-TMPDA, were chosen as the matrices. Our findings revealed that 20 wt% loading of HKUST-1 was capable of improving C2H4 permeability (155% for ODPA-TMPDA and 69% for 6FDA-TMPDA) without excessively sacrificing the C2H4/C2H6 selectivity. The C2H4 and C2H6 diffusivity, as well as solubility, were also improved substantially as compared to the pure polymeric membranes. Overall, our results edge near the upper bound, confirming the effectiveness of leveraging nanocrystal HKUST-1 filler for performance enhancements in mixed-matrix membranes for C2H4/C2H6 separation.

“…It originated from the partial decomposition of MOF-199 at higher concentration, which would be verified later. [35] The cross-sectional structures of the membranes are shown in Figure 3. The pristine PVDF membrane, M0, possessed typical asymmetric structure of finger-like sublayer on the top and sponge-like structure on the bottom (Figure 3a), [36] and the composite membrane, M3, showed the similar structure compared with M0 ( Figure 3b).…”

MOF-199@PVDF composite membranes are prepared by blending with different amounts of ultrasonic synthesized MOF-199 nanomaterials for improving the pure water flux (PWF) and achieving better antifouling and antibacterial performance. The membrane morphology, elemental composition, and surface properties are analyzed by various means of characterizations, including scanning electron microscopy, energy-dispersive X-ray spectroscopy, and water contact angle measurements. The performance of the modified membranes is also determined from the perspective of the PWF, bovine serum albumin rejection, as well as antifouling and antibacterial properties. Due to the variation in the viscosity of dope solution, the composite membranes possess remarkably different morphology, and the M5 membrane, which exhibited a sponge-like structure, the largest surface pore size, and the highest porosity, shows the highest PWF, reaching up to 185.05 L/m 2 h. Moreover, with the incorporation of MOF-199 nanocrystals, the antifouling property, together with the antibacterial property, toward both gram-negative bacteria and gram-positive bacteria, based on M5 and M7 membranes, increases dramatically compared with the pristine polyvinylidene fluoride membrane. In addition, the long-term permeation performance and copper leakage of the membrane are investigated. As a result, the composite membrane, M5, shows great potential in real water treatment.

“…In the petrochemical, natural gas, and fuel industry [1,2], for example, the purification of commodity gases, like propane, propylene, hydrogen, methane, and ammonia, is vital for the production of other goods like fuels (e.g., propane, hydrogen, methane) [3][4][5][6][7][8][9][10][11], polymers (e.g., polypropylene from propylene) [12][13][14][15], and fertilizers (e.g., ammonium salts) [16,17]. Recently, environmental applications for gas separations have also been explored mainly for the capture and sequestration of carbon dioxide from the burning and gasification of coal in the generation of electricity and the production of hydrogen [18][19][20].…”

“…A variety of industrial, energy, and environmental membrane-based gas separation applications have been targeted, some already at the industrial scale. Separations such as H2/N2, H2/CO2, He/H2, CH4/CO2, N2/CO2, O2/N2, NH3/H2/N2, N2/CH4, C3H6/C3H8 [11], C3H8/N2 [5], C3H6/C3H8/N2 [12], and C2H4/C2H6 [8,9], and other organic vapors are some examples of where membranes could be employed to provide a cost effective separation process [51,52]. Owing to the nature of membranes as barrier materials, the operating conditions required in industry to separate a particular gas mixture impose constraints and challenges on the materials and manufacturing processes required for a membrane to be successfully used in industry.…”

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

et al. 2016

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.
