A system for NOreduction in combustion gases, especially from diesel engines, incorporates an oxidation catalyst to convert at least a portion of NO to NO, particulate filter, a source of reductant such as NHand an SCR catalyst and methods for operating such a system are disclosed. Considerable improvements in NOconversion and soot reduction are observed even at relatively low operating temperatures.

Selective catalytic reduction of NO in combustion gases, especially from diesel engines, utilizes a system incorporating an oxidation catalyst to convert at least a portion of NO to NO , a particulate filter downstream of the oxidation catalyst, a source of reductant such as NH or urea for injection downstream of the particulate filter, and an SCR catalyst located downstream of the point of injection of the reductant. Considerable improvements in NO conversion are observed.

System for NOx reduction in exhaust gases

A canister ( ) contains a catalyst for generating NO and a filter ( ) for trapping PM, e.g. from diesel engines. The filter is thermally isolated from the canister, and preferably is surrounded by an annular monolith comprising the NO oxidation catalyst or a SCR catalyst. The invention facilitates the combustion of PM even at low exhaust gas temperatures, in a compact device.

Device and method for removing sooty particulate from exhaust gases from combustion processes

A heavy duty diesel engine having an exhaust system incorporating a catalyst to convert NO to NO and a particulate trap on which soot particles are continuously oxidized, and a portion of the exhaust gases are recirculated through a cooler and exhaust gas flow valve before being mixed with air and fed to the engine cylinders. The system also incorporates a sensor to detect the amount of NOx in the exhaust to adjust the gas flow valve, thereby adjusting the portion of recirculated exhaust gas fed to the engine cylinders.
