摘要

This paper gives an overview of diverse microporous ceramic membranes which are under investigation at IEF-1 for H2/CO2 separation in power plants. A summary is given of what has been accomplished in the synthesis of multilayer membranes in our laboratory and the progress in the area of thin-film deposition of silica and non-silica membranes is illustrated. These membranes have to combine the required gas separation factor and permeation and contaminants such as water and acidic vapors must be dealt with. Stabilized microporous SiO_2 membranes are one of the candidate materials due to their demonstrated resistance to water vapor. In our lab, we achieved a high H_2/CO_2 selectivity for such membranes by optimizing all conditions in the manufacturing procedure (support, sol preparation, mesoporous intermediate layers, cleanroom coating). In addition, the development of an Y_2O_3-stabilized ZrO_2 membrane for application under harsher conditions, including a high amount of acid containments, is also reported.
