Abstract (en)
[origin: WO2019032409A1] Coated particulate filters and methods for their manufacture disclosed. The particulate filters comprise a honeycomb body having a plurality of porous channel walls defining channels extending from an inlet end to an outlet end. The honeycomb body has an upstream zone having an upstream zone gas permeability and a downstream zone disposed closer to the outlet end than the upstream zone and having a downstream zone gas permeability. SCR catalyst is present in a loading in the downstream zone at localized loading in a range of from about 50 g/L to about 200 g/L such that the upstream zone gas permeability is in a range of about 5 to about 90 times the downstream zone gas permeability.
