abstract = {In this work, we investigate the effect of coal power plant
exhaust gas on amino-modified mesoporous ceramic membranes.
The testing of ceramic membranes in the flue gas of
coal-fired power plants represents a new approach, as
testing under simulated flue gas conditions has already been
undertaken, but not yet during direct exposure to exhaust
gas. Flue gas exposure trials were carried out at a
lignite-fueled power plant and a hard-coal-fueled power
plant. Most experiments were conducted using a test rig
designed to bring planar membrane samples in direct contact
with unconditioned flue gas in the exhaust gas channel.
Another test rig was designed to test membrane modules with
pre-treated flue gas. The tested membranes had an
asymmetrical structure consisting of a macroporous α-Al2O3
support coated with a mesoporous γ-Al2O3 or 8YSZ
interlayer. The microporous functional top layer was made of
amino-functionalized silica. The tests revealed different
degradation mechanisms such as gypsum/fly ash deposition on
the membrane surface, pore blocking by water condensation,
chemical reactions and phase transformation. A detailed
analysis was carried out to evaluate their impact on the
membrane in order to assess membrane stability under real
conditions. The suitability of these membranes for this
application is critically discussed and an improved mode of
membrane operation is proposed.},
