采用线管式脉冲电晕反应器，研究了低温等离子体与原位吸收相结合脱除NO的工艺。在反应器的导线上施加高脉冲电压，并将管接地。对于结合原位吸收的反应器，接地电极被Ca（OH）2层覆盖作为原位捕获NO氧化产物的吸附剂。结果表明，与不添加Ca（OH）2的反应器相比，添加Ca（OH）2的反应器对NO的去除率更高，同时，反应器出口NO2浓度也被抑制在10 ppm以下。结果表明，Ca（OH）2对NO 2的原位吸附是促进NO去除的主要原因。气流中O2和水蒸气的存在有利于NO的氧化，从而导致NO去除率的显著提高。© 2004美国化学工程师学会AIChE J，50：2676-2681，2004
Removal of NO by nonthermal plasma, combined with in situ absorption, was experimentally investigated with a wire-in-tube pulsed-corona reactor. High pulse voltage was applied to the wire of the reactor and the tube was grounded. For the reactor combined with in situ absorption, the grounding electrode was covered by a Ca(OH)2 layer as the sorbent for in situ capture of the NO oxidation products. It was found that NO removal was much higher by the reactor combined with in situ absorption than by the reactor without Ca(OH)2 sorbent and, meanwhile, the outlet NO2 concentration from the reactor was also suppressed to less than 10 ppm. It was indicated that in situ absorption of the NO2 by Ca(OH)2 was responsible for the promotion of NO removal. The existence of O2 and water vapor in the gas stream is beneficial for NO oxidation, therefore resulting in the significant increase of NO removal. © 2004 American Institute of Chemical Engineers AIChE J, 50: 2676–2681, 2004
