    摘要: 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.

    摘要: In one embodiment, a method of heating an exhaust treatment device can comprise: generating reformate in a reformer, wherein the reformate comprises hydrogen; introducing oxygen to the reformate prior to combining the reformate with another stream; combusting a portion of the reformate and generating an exotherm to form heated reformate; and introducing the heated reformate to the exhaust treatment device. In one embodiment the exhaust system can comprise: a reformer; a reformate conduit disposed in physical communication with a reformate outlet of the reformer; an exhaust treatment device disposed in fluid communication with the reformer; and an oxygen supply disposed in fluid communication with the reformate conduit such that oxygen can be introduced into the reformate conduit upstream of a reformate conduit outlet, wherein the reformate conduit outlet is disposed in physical communication with an exhaust conduit and/or the exhaust treatment device.
