This abstract first appeared for US patent application 18702986 titled 'EMISSIONS TREATMENT ARTICLES WITH INORGANIC FILTRATION DEPOSITS AND CATALYTIC MATERIAL



Original Abstract Submitted

A filtration article comprises inorganic deposits disposed at inlet sides of porous ceramic base portions of a plugged honeycomb filter body; and a catalytic material, e.g., a three-way conversion (TWC) catalytic material, disposed at outlet sides of porous ceramic base portions of the plugged honeycomb filter body. Interposing regions are located between the inlet sides and the outlet sides of the porous ceramic base portions. A majority or all of the inorganic deposits are spaced away from a majority of the catalytic material by the interposing region at a given axial location and/or across an entire axial length. The inorganic deposits and the porous ceramic base portions are not hydrophobic.
