Abstract (en)
[origin: WO2004058642A1] A multi-stage NOx reduction system employs catalysts effective at different temperature ranges and can have reagent injectors associated with each, for use in series or in parallel. A controller directs reagent introduction to one catalyst or the other as temperature and other conditions dictate. Valving can redirect exhaust to particular catalyst zones, if necessary.
