Abstract
In filters for the purification of exhaust gases from diesel engines, the soot particles deposited are periodically burnt at temperatures between 550 and 700 DEG C.
The soot combustion temperature is reduced to between 400 and 550 DEG C by using filters composed of an open-pore foam ceramic which is produced by coating a bakeable, open-pore body with ceramic powder suspension, baking the support material at temperatures of 100-500 DEG C and then sintering at elevated temperatures and which have a self-supporting ceramic structure with an internal surface of the entire pore system of 1 m<2>/l to 10 m<2>/l and an open porosity of 55 to 92%.
The soot combustion temperature is even reduced to 350 DEG C by coating with catalytically active substances.
