Abstract
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.
