Abstract
Official abstract text for this publication.
An exemplary method and associated architecture for reducing NO x and particulate matter emissions in an exhaust stream may include passing the exhaust stream through a catalytic oxidation reactor; passing the exhaust stream through a two-way selective reduction catalyst particulate filter located downstream of the catalytic oxidation reactor, wherein the two-way selective reduction catalyst particulate filter may include a wall flow filter substrate having internal walls coated with a first selective catalytic reduction catalyst; and passing the exhaust stream through a catalytic reduction reactor located downstream of the two-way selective reduction catalyst particulate filter, wherein the catalytic reduction reactor may include a second selective catalytic reduction catalyst.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for reducing NO x and particulate matter emissions in an exhaust stream comprising: a catalytic oxidation reactor that oxidizes carbon monoxide, hydrocarbons, and NO wherein said catalytic oxidation reactor comprises a dual zone type catalytic oxidation reactor in which said exhaust stream first passes through a platinum- and palladium-containing front side, which oxidizes hydrocarbons and carbon monoxide to carbon dioxide, and subsequently passes…
