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 mu m < pore size < 0.4 mu m), a mesoporous gamma-Al2O3 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 manufacturing route for the different material layers are discussed. Some special attention was given to the development of an alternative porous support, adapted from a Reaction Bonded Al2O3 (RBAO)-process and to the tailoring of the pore texture of the gamma-Al2O3 interlayer. Preliminary dip coating experiments proved that the formation of a thin clay or pillared clay layer on an (alpha + gamma)-Al2O3 support is possible. (C) 1996 Elsevier Science Limited.
