Samenvatting:
A novel design of an electrochemical reactor for filtering and continuouscombustion of soot particles was developed. Such a reactor consists
of a porous, oxygen-ion conducting material covered by catalytically
active, electron-conductive electrodes, electrical connections and an
external power supply. The manufacturing process was developed for high-porosity,
ion- and electron-conducting ceramic monoliths from nanosize powders
by extrusion followed by coating techniques. The performed catalytic
tests proved that the efficiency of the reactor for soot removal is
above 90% at low flow conditions (GHSV = 13 000-1) and 75%
for high flow (GHSV = 39 000-1) in the temperature range
250-500°C.
