Abstract
The invention provides devices and methods for generating Hand CO in an Ocontaining gas stream. The invention also provides devices and methods for removal of NOfrom an Ocontaining gas stream, particularly the oxygen-rich exhaust stream from a lean-burning engine, such as a diesel engine. The invention includes a fuel processor that efficiently converts added hydrocarbon fuel to a reducing mixture of Hand CO. The added fuel may be a portion of the onboard fuel on a vehicle. The Hand CO are incorporated into the exhaust stream and reacted over a selective lean NOcatalyst to convert NOto N. thereby providing an efficient means of NOemission control.
