ABSTRACT:
One embodiment of a method of operating a NOx abatement system comprises: introducing an exhaust stream to an ammonia generator in a normal flow direction, adsorbing NOx from the exhaust stream in the ammonia generator, diverting the exhaust stream around the ammonia generator, introducing hydrogen to the ammonia generator in a direction opposite the normal flow direction, and generating ammonia within the ammonia generator.
