Abstract
In one embodiment, an exhaust treatment system comprises a selective catalytic reduction device, an off-line reformer disposed in selective fluid communication with and upstream of the selective catalytic reduction device, and a plasma reactor disposed downstream of and in fluid communication with the off-line reformer, and disposed upstream of and in fluid communication with the selective catalytic reduction device. The selective catalytic reduction device is capable of storing ammonia and of enabling the reaction of the ammonia with NOx. The reformer is capable of producing a reformate comprising hydrogen and nitrogen. The plasma reactor is capable of producing ammonia from the reformate, and is a thermal plasma reactor or a surface discharge non-thermal plasma reactor.
