standard
posted on 2018-08-09, 00:00 authored by James Zokoe, Paul J. McGinnA diesel soot filter includes a substrate having a surface disposed at least partially within a fluid path of the diesel soot filter. A glass catalyst is disposed on the surface of the substrate such that an exhaust gas contacts at least a portion of a surface of the glass catalyst as the exhaust gas moves within the diesel soot filter. The glass catalyst comprises a plurality of alkali metal ions disposed within the glass catalyst and releasable to the surface of the glass catalyst at a controlled rate and the alkali metal ions combust with the soot as the exhaust gas travels along the fluid path. An oxide basis of the glass catalyst comprises Silicon (Si), Potassium (K), Cesium (Ce), and Zirconium (Zr).
