abstract = {Metal-supported silica membranes are attractive candidates
for CO2 capture from the exhaust of coal-fueled power
plants. Compared to their full ceramic counterparts, the
introduction of the metal support facilitates sealing of the
membrane by established technologies, such as welding, and
enhances the robustness of the membrane in the harsh
environment of the power plant. As well-known from other
steel components in flue gas desulfurization units,
long-term corrosion resistance of the metal support is
mandatory for the success of this new membrane concept. In
the present work, a research concept is introduced enabling
a systematic benchmark of stainless steels regarding their
suitability to be used for the metal support of the CO2
selective silica membranes. The study combines field tests
of porous samples in direct contact with the exhaust gas of
a lignite-fueled power plant and standardized corrosion
tests of dense and porous samples in the laboratory
according to DIN 50918 using exhaust gas condensate as the
corrosive medium. Preliminary results are achieved on
austenitic steel (AISI 316L) as well as on two ferritic
steels (Crofer22APU, Plansee ITM). Ferritic steels are
chosen due to their availability as substrates with
well-defined porosity and with adapted thermal expansion
coefficient enabling successful coating of the CO2 selective
silica membrane.},
