“…It can be concluded that by adding of fillers and MOFs the performance of such membranes can be improved. Guo et al [87] prepared a new mixed-matrix membrane by incorporation of an amine-functionalized MOF. The CO 2 /CH 4 separation factor for this membrane was reported to be 29.2.…”

Removal of CO 2 from natural gas is necessary to purify the gas and to enhance its calorific value. Membrane technology is an efficient technique for CO 2 removal due to its ease of operation and low cost. Polymeric membranes exhibit excellent separation performance which is affected by plasticization and swelling in the membrane. Recent technological advancements and major problems in polymeric membranes are reported in this review. Separation performance of polymeric membranes is highlighted in terms of permeability and selectivity. Moreover, techniques to overcome the major problems in polymeric membranes are reviewed. Commonly, cross-linking and thermal treatment are used to minimize the effect of plasticization and swelling in the membrane. For future perspectives, there is a need to find more efficient methods to overcome these problems.

“…In contrast, the selectivity showed the opposite trend BHPA > PEI > EA. It could be expected that the incorporation of porous particles on membranes would provide additional channels that improve the diffusion of penetrant species resulting in the increase on gas permeability . The impregnation of zeolite with the smallest size molecule of EA contributed to achieve MMM more efficient and permeable to CO 2 .…”

Flat mixed matrix membranes (MMMs) comprising polysulfone and clinoptilolite-type natural zeolite were prepared by casting. Zeolite was modified with three alkylamines: ethanolamine (EA), bis(2-hydroxypropyl)amine (BHPA), and polyethylenimine (PEI) by the impregnation method. Impregnated zeolite samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and N 2 adsorption-desorption. The alkylamine loading extent determined by thermogravimetric analysis was 5.2, 4.8, and 8.5% for EA, BHPA, and PEI, respectively. Analyses of MMMs showed that the incorporation of impregnated zeolite affected the glasstransition temperature (T g ) and mixed-gas transport properties. In this regard, a decreasing trend of the T g values from 185.5 C for the polymeric membrane up to 176.6 C for Clino-EA-based MMM was recorded. In addition, the gas separation performance was evaluated at two different feed pressures. At 50 psi, MMMs showed an enhancement up to 30% on the CO 2 permeability (22.79 Barrer) and 55% on the CO 2 /CH 4 selectivity (45.78) in comparison with the polymeric membrane (CO 2 permeability 17.34 Barrer; CO 2 /CH 4 selectivity 29.38). These values varied depending on the alkylamine, BHPA being the most selective.

“…Auf eine nachteilige Leistung stieß man als Titan‐basiertes und Amin‐funktionalisiertes MIL‐125(Ti)‐NH 2 (Ti 8 O 8 (OH) 4 (NH 2 ‐bdc) 6 ) (NH 2 ‐bdc=2‐Amino‐1,4‐benzoldicarboxylat) als MMM‐Füllstoff für die Trennung eines CO 2 /CH 4 ‐Gasgemisches verwendet wurde. Mit Polysulfon (PSF) als Polymermatrix sank die Selektivität von 27 für reine PSF‐Membranen auf 6 bei hohen Füllstoffbeladungen (30 Gew.‐%), zusammen mit einer gesteigerten Permeabilität von 7 auf 37 Barrer, ein Ergebnis unselektiver Fehlstellen, die durch schlechte Polymer‐Füllstoff‐Haftung entstanden . Allerdings ergaben MIL‐125‐NH 2 ‐MMMs mit Matrimid (30 Gew.‐% Beladung) deutlich gesteigerte Trennergebnisse, die zu einem Anstieg der Selektivität um 550 % führten, verbunden mit 35 % höherer CO 2 ‐Permeabilität, verglichen zu den vorstehend erwähnten PSF‐MMMs.…”

Die Forschung zu ausgedehnten porösen Materialien wie Metall‐organischen und porösen organischen Gerüstverbindungen (MOFs und POFs) sowie den analogen Metall‐organischen Polyedern (MOPs) und porösen organischen Käfigen (POCs) hat sich im letzten Jahrzehnt stark entwickelt. Mit ihrer chemischen und strukturellen Vielfalt und bemerkenswerten Porosität wurden MOFs als neue Adsorbentien für industrielle Gastrennungen und als vielversprechende Füllstoffkomponenten für leistungsstarke gemischt(Mixed)‐Matrix‐Membranen (MMMs) vorgeschlagen. Die Forschung in diesem Bereich konzentrierte sich auf die Verbesserung der chemischen Kompatibilität der MOFs mit der Polymerphase durch sinnvolle Funktionalisierung der organischen MOF‐Linker, auf die Modifizierung der MOF‐Oberflächenchemie und in jüngster Zeit auf Untersuchungen, wie Partikelgröße, ‐morphologie und ‐verteilung die Trennleistung erhöhen. Andere Füllstoffmaterialien, wie POFs, MOPs und POCs, werden ebenfalls als Additive für MMMs untersucht und zeigen eine bemerkenswerte Wirkung gegen Polymeralterung und ausgezeichnete chemische Kompatibilität mit handelsüblichen Polymeren. Dieser Aufsatz gibt einen Überblick zum Stand der Technik im MOF‐MMM‐Aufbau und zu aktuellen Anwendungen von porösen organischen Gerüsten und molekularen Additiven für MMMs.
