Abstract: A particulate filter and method of manufacture. The particulate filter includes intersecting walls that define longitudinally extending channels The intersecting walls comprise a porous ceramic material having a bare microstructure that comprises an interconnected network of porous spheroidal ceramic beads that has an open intrabead porosity within the beads and an interbead porosity defined by interstices between the beads. Catalyst particles are deposited at least partially within the intrabead porosity within the interbead porosity. The bare microstructure has a bimodal pore size distribution in which an intrabead median pore size of the intrabead porosity is less than an interbead median pore size of the interbead porosity. The filter has a trimodal pore size distribution comprising a first peak corresponding to the interbead porosity, a second peak corresponding to the intrabead porosity, and a third peak corresponding to the intrabead porosity as blocked by the catalyst particles.

Abstract: An exhaust gas purifying system for an engine includes a three-way catalyst, a particulate filter, an ammonia sorbent unit, an exhaust gas purifying catalyst unit, and a gas injection component including an oxygen-containing gas, all coupled to an exhaust line. Methods for purifying exhaust gas from an engine include exposing the exhaust gas to a three-way catalyst and a particulate filter, thus generating ammonia. The ammonia may be stored in an ammonia sorbent unit during a cold start condition. An oxygen-containing gas may be injected into the exhaust line. Once the ammonia sorbent has reached a desorption temperature, the ammonia may be released into the exhaust line and exposed to an exhaust gas purifying catalyst unit. The exhaust gas purifying catalyst partially oxidizes the ammonia to nitrous oxides (NOx) and subsequently catalyzes a reaction between the remaining ammonia and the nitrous oxides to give nitrogen gas and water.
