Title:
WALL-FLOW FILTER AND METHODS FOR INHIBITING RELEASE OF VERY FINE NANO-PARTICLES IN EXHAUST EMISSIONS
Document Type and Number:
WIPO Patent Application WO/2024/039490
Kind Code:
A3
Abstract:
A wall-flow filter for inhibiting the emission of very fine nano-particles. The wall-flow filter includes a honeycomb body including an intersecting array of filter walls formed of a porous material and defining channels extending through the honeycomb body between an inlet face and an outlet face of the filter. The channels comprise a plurality of inlet channels that are open at the inlet face and plugged at the outlet face and a plurality of outlet channels that are open at the outlet face and plugged at the inlet face. A mixed metal oxide particle deposition is located on and/or in the filter walls of the wall-flow filter. The mixed metal oxide particle deposition comprises precious metals in an amount of less than 0.1 wt%.
