Shaping of Multilayer Ceramic Membranes by Dip Coating

摘要

For the development of new ceramic membranes for gas separative and catalytic membrane reactors, multilayer membranes were synthesized. These membrane configurations consist of three layers: a porous support (0·1 μm ＜ pore size ＜ 0·4 μm), a mesoporous γ-Al_2O_3 interlayer and a gas separative top layer. Different materials for the top layer are being considered. In this contribution, the characterization of the Membranes and the optimization of the manufatur- Ing route for the different material layers are dis- Cussed.
