Title (EN) MICROPOROUS ALUMINOPHOSPHATE MOLECULAR SIEVE MEMBRANES FOR HIGHLY SELECTIVE SEPARATIONS
(FR) MEMBRANES DE TAMIS MOLÉCULAIRE EN ALUMINOPHOSPHATE MICROPOREUSES POUR SÉPARATIONS HAUTEMENT SÉLECTIVES
Abstract:
(EN) The present invention discloses microporous aluminophosphate (AlPO4) molecular sieve membranes and methods for making and using the same. The microporous AlPO4 molecular sieve membranes, particularly small pore microporous AlPO-14 and AlPO-18 molecular sieve membranes, are prepared by three different methods, including in-situ crystallization of a layer of AlPO4 molecular sieve crystals on a porous membrane support, coating a layer of polymer-bound AlPO4 molecular sieve crystals on a porous membrane support, and a seeding method by in-situ crystallization of a continuous second layer of AlPO4 molecular sieve crystals on a seed layer of AlPO4 molecular sieve crystals supported on a porous membrane support. The microporous AlPO4 molecular sieve membranes have superior thermal and chemical stability, good erosion resistance, high CO2 plasticization resistance, and significantly improved selectivity over polymer membranes for gas and liquid separations, including carbon dioxide/methane, carbon dioxide/nitrogen and hydrogen/methane separations.
(FR) La présente invention concerne des membranes de tamis moléculaire en aluminophosphate (AlPO4) microporeuses et leurs procédés de fabrication et d'utilisation. Les membranes de tamis moléculaire en AlPO4 microporeuses, notamment les membranes de tamis moléculaire en AlPO-14 et AlPO-18 microporeuses à petits pores, sont préparées par trois procédés différents, y compris une cristallisation in situ d'une couche de cristaux de tamis moléculaire en AlPO4 sur un support de membrane poreuse, l'enduction d'une couche de cristaux de tamis moléculaire en AlPO4 reliés à un polymère sur un support de membrane poreuse et un procédé d'ensemencement par cristallisation in situ d'une seconde couche continue de cristaux de tamis moléculaire en AlPO4 sur une couche germe de cristaux de tamis moléculaire en AlPO4 sur un support de membrane poreuse. Les membranes de tamis moléculaire en AlPO4 microporeuses présentent une stabilité thermique et chimique supérieure, une bonne résistance à l'érosion, une résistance élevée à la plastification au CO2 et une sélectivité considérablement améliorée par rapport aux membranes polymères pour les séparations de gaz et de liquides, y compris les séparations dioxyde de carbone/méthane, dioxyde de carbone/azote et hydrogène/méthane.
