Abstract:

Les réseaux zéolithiques à base d'imidazolate (e.g. ZIF-8) sont des matériaux membranaires attractifs pour la séparation de gaz, sous réserve de pouvoir disposer de membranes de haute qualité, stables et reproductibles sur des supports industriels. Dans ce travail plusieurs stratégies ont été examinées pour développer des membranes nanocomposites à base de ZIF-8 confiné dans les macropores de supports céramiques tubulaires. Trois approches ont été comparées: i) croissance de germes, ii) croissance in situ et iii) conversion de ZnO. L'influence des paramètres de synthèse (formulation des soluti

Abstract:

In this study, pervaporation, a membrane-based process was studied for in-situ separation of butanol. This technique has a great potential due to its high selectivity, low energy requirement and high efficiency. The primary objective was to improve the performance of the Polydimethylsiloxane (PDMS) membrane for the pervaporation separation and the recovery of butanol by adding nanoparticles into its matrix to make mixed matrix membrane (MMM). These nanoparticles included zinc-based Metal Organic Frameworks (MOFs) and zinc oxide. Different particle sizes of zeolitic imidazolate framework (ZIF-8

Abstract:

Mixed matrix membranes (MMMs) have gained importance because they combine the desirable properties of the polymers and the organic/inorganic filler materials and they may have a very big potential. In this study polyethersulfone (PES) was used as polymeric material, and Zeolitic Imidazolate Framework-8 (ZIF-8) was used as porous filler material, and 2-hydroxy 5-methyl aniline(HMA), was used as a third component in membrane formulation. In this study, ZIF-8 crystals were synthesized with varying particle sizes, and a novel recycling methodology was developed to improve the efficiency of ZIF-8 p

Esta tesis aborda las Redes Metal Orgánicas (MOFs), las cuales exhiben propiedades porosas, así como grandes áreas superficiales. Son eficientes en procesos de tamizado molecular, almacenamiento y catálisis heterogénea. Se sintetizaron membranas de dos diferentes MOFs, cobre y ácido benceno-1,3,5-tricarboxilico (BTC), y iones de zinc y 2-metilimidazol como ligando, este material es mejor conocido como ZIF-8. Las membranas homogéneas de CU-BTC y ZIF-8 fueron sintetizadas mediante el proceso de crecimiento secundario; y a través de la funcionalización de la superficie del soporte, para posterior

Abstract:

Polymeric membranes exhibit a trade-off between permeability and selectivity in gas separations which limits their viability as an economically feasible post-combustion carbon capture technology. One approach to improve the separation properties of polymeric membranes is the inclusion of particulate materials into the polymer matrix to create what are known as mixed matrix membranes (MMMs). By combining the polymer and particulate phases, beneficial properties of both can be seen in the resulting composite material. One of the most notable challenges in producing mixed matrix membranes is in t

Abstract:

In the last decade, many attempts were made to put metal organic frameworks (MOFs) in industrial applications, but most of these efforts weren’t successfully. As one of the few MOFs produced on industrial scale, ZIF-8 has interesting pore size, huge internal surface area and great thermal and chemical stability. Therefore, ZIF-8 might become the first MOF, which will be applied in industrial separation processes. In this thesis, a synthesis study is presented, which leads to a cheap and convenient way to fabricate defect-free and thin ZIF-8 membranes on porous polymeric supports showing high

However, the separation performance of MMMs was influenced by the dispersion of inorganic and the interfacial adhesion between the organic and inorganic phase. Therefore, the choice of suitable materials and the applicable methods to synthesis a defect-free MMMs with good performance have been discussed in the recent works.
