IMPROVED CATALYZED SOOT FILTER AND METHOD (S) TO MAKE THESE |
摘要 |
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. |
