Abstract (en)
[origin: WO2009117978A1] The invention relates to a composite membrane for selective gas separation, comprising a layer system having a through-and-through porous, mechanically stable carrier layer, which has an average pore size in the µm range, further having at least one through-and-through porous intermediate layer, which is disposed on the carrier layer and has an average pore size in the range between 2 and 200 nm, and further having a gas-tight functional layer, which is disposed on the intermediate layer and is made of mixed-conductive material having a maximum layer thickness of 1 µm. The carrier layer comprises structural ceramics, a metal or a cermet and has a layer thickness of no more than 1 mm. The intermediate layer is present in a total layer thickness of no more than 100 µm and has an average pore size in the range of 10 and 100 nm. The functional layer comprises a perovskite, a fluorite, or a material having a K2NiF4 structure, such as La1-xSrxCo1-yFeyO3-8 (LSCF). The layer thickness of the functional layer is no more than 50 nm, particularly between 25 and 400 nm. In order to produce said composite membrane, at least one porous intermediate layer is applied onto a through-and-through porous, mechanically stable carrier layer, which has an average pore size in the µm range, said intermediate layer having an average pore size in the range between 2 and 200 nm. A further gas-tight, functional layer made of a mixed-conductive material and having a maximum layer thickness of 1 µm is applied onto said intermediate layer.
