    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 flow switch can comprise: a deflector having a diverging upstream portion; an aperture located in a downstream portion of the deflector; and a divider disposed downstream of the deflector. The deflector can be capable of diverting a fluid stream that contacts the upstream portion, around the deflector. The aperture can be capable of allowing a flow of a displacing fluid such that the displacing fluid can inhibit the diverted fluid stream from converging to pass through the divider. The divider can be capable of allowing a flow of the displacing fluid therethrough.

    摘要： A surface discharge non-thermal plasma reactor includes a plurality of surface discharge reactor elements arranged in a stack and having a surface discharge gap formed between adjacent pairs of elements. Individual surface discharge elements include a dielectric substrate having disposed thereon first and second polarity surface discharge electrodes. Surface discharge electrode patterns and substrate configurations are provided to selectively control the volume of nitric oxide (NO) produced from a nitrogen-containing gas stream being treated in the reactor. In a preferred embodiment, surface discharge electrode and dielectric substrate configurations are arranged to maximize the production of NO. The surface discharge electrodes and substrates are combined and connected to a power supply to form various embodiments such as reactor stacks having a plurality of positive surface discharge gaps, reactor stacks having a plurality of negative surface discharge gaps, and reactor stacks having a plurality of alternating positive and negative surface discharge gaps.
