ABSTRACT:
Suspended particles in exhaust gases, such as carbon and lead particles in internal combustion engine exhaust gases, are removed by passing the gases through a coarse filter and then through a fine filter. The filters may comprise a ceramic foam material and a catalyst material effective for the conversion of the carbon particles and/or gaseous pollutants in the exhaust gases to innocuous entities may be deposited on the filters.
