Abstract
Ceramic filter materials are mostly applied when other materials have failed due to high temperature stability, corrosion, and/or high material costs. This chapter discusses some of the ceramic filter materials used in hot gas filtration, liquid filtration, pervaporation (PV)/vapor permeation (VP), gas separation and diesel particulate filter. Hot gas filtration for pressurized coal-fired power systems has been successfully demonstrated in technical and semi-commercial installations, for both combustion and gasification systems. Silicate-bonded SiC candles have shown the longest and most successful applicability of all tested materials.
