Beschreibung
Zusammenfassung:	The invention relates to a membrane for the filtration of molecular gases, such as hydrogen, consisting of a ceramic porous support which essentially comprises magnesium aluminium spinel, said support being impregnated with a silica-based xerogel layer. The invention also relates to a method of preparing one such membrane. The invention further relates to the use of a support that essentially comprises magnesium aluminium spinel in a hydrogen filtration membrane. La présente invention concerne une membrane de filtration de gaz moléculaires tels que l'hydrogène, comprenant un support poreux céramique constitué essentiellement de spinelle alumino-magnésique, ledit support étant imprégné d'une couche de xerogel à base de silice. L'invention a également pour objet un procédé de préparation d'une telle membrane. L'invention concerne également l'utilisation d'un support constitué essentiellement de spinelle alumino-magnésique dans une membrane de filtration de l'hydrogène.
