AB  - Nanostructured gas separation membranes are discussed to make an important contribution for CO2 capture strategies in fossil power plants. Traditionally, gas separation membranes consist of polymers, which have restrictions regarding their mechanical, chemical and thermal stability. To overcome this drawback and to ease the assembling of membrane modules by established joining techniques like welding, a novel hybrid metallic-ceramic membrane is developed. The membrane is based on a porous metallic substrate, which is modified by a powder metallurgical interlayer made of 310S powder. Afterwards, a 8 YSZ ceramic interlayer is brought up by suspension coating. This interlayer bridges the large pore size gap between substrate and toplayer and acts as support for the gas separation membrane itself. Since pore sizes in the sub-nanometer range are pre-requisite for the separation of hydrogen (H2), nitrogen (N2) and carbon dioxide (CO2) gases, nano-particulate sol-gel-technology was the preferred method for the manufacturing of the SiO2-based gas separation membrane itself. Recently, H2/CO2 gas separation could be demonstrated with this new kind of membrane on a laboratory scale. Furthermore, first tests were conducted annealing this membrane in the flue gas of a hard coal fired power plant to investigate its stability under real conditions.
