Abstract:
System for the removal of noxious compounds and particulate matter from exhaust gas of a compression ignition engine comprising a three way catalyst unit having an NH 3 -SCR activity, an ammonia oxidation activity and an adsorption activity of volatile vanadium and tungsten compounds volatilized off an upstream SCR active catalyst.

Claim (Index 1):
A system for the removal of volatile organic compounds, particulate matter and nitrogen oxides from exhaust gas of a compression ignition engine comprising\n (a) an oxidation unit with a catalyst active in oxidation of volatile organic compounds and carbon monoxide to carbon dioxide and water and nitrogen oxide to nitrogen dioxide; (b) means for introducing a urea solution into the exhaust gas from unit (a); (c) a downstream catalysed wall flow particulate filter consisting of a plurality of longitudinal inlet flow channels and outlet flow channels separated by gas permeable porous partition walls, each inlet flow channel having an open inlet end and a closed outlet end, and each outlet flow channel having a closed inlet end and an open outlet end, the wall flow filter is catalysed with an NH 3 -SCR active catalyst comprising oxides of vanadium and tungsten arranged within the gas permeable porous partition walls and/or on the plurality of the inlet and/or outlet channels of the wall flow particulate filter; (d) a downstream three way catalyst unit having an NH 3 -SCR activity, an ammonia oxidation activity and an adsorption capacity for volatile vanadium and tungsten compounds volatilized off the SCR active catalyst of the particulate filter (c), the three way catalyst comprising high surface compounds selected from high surface metal oxides, zeolites, silica, non-zeolite silica alumina, and mixtures thereof.
