Abstract: An improved soot catalyst is comprised of an alkali compound at least partially coated by a ceramic coating comprised of C bonded to a metal, semimetallic element or combination thereof. The improved soot catalyst may be employed in catalyzed Diesel particulate filters. In one method to make a catalyzed Diesel particulate filter, the improved filter is made by contacting a porous ceramic body having an alkali catalyst thereon, coating the alkali catalyst with an organic ceramic precursor, heating the ceramic body to a temperature in an atmosphere sufficient to decompose the organic ceramic precursor to form the soot catalyst on the porous ceramic body without volatilizing substantial amount of the alkali catalyst away.

Abstract: A catalyzed Diesel soot filter and process. The Diesel soot filter incorporates a porous filter element coated with a catalytic agent so that Diesel soot from Diesel exhaust gas is deposited into contact with the catalytic agent when Diesel exhaust gas is passed through the porous filter element and so that the ignition temperature or oxidation temperature of the deposited Diesel soot is reduced. The catalytic agent is a mixture of alkali metal and cerium oxides. The mole ratio of alkali metal to cerium of the catalytic agent is in the range of from 0.5 to 5.
