The production of NO_x from air and air + O₂ is investigated in a pulsed powered milli-scale gliding arc (GA) reactor, aiming at a containerized process for fertilizer production. Influence of feed mixture, flow rate, temperature, and Ar and O₂ content are investigated at varying specific energy input. The findings are correlated with high-speed imaging of the GA dynamics. An O₂ content of 40–48% was optimum, with an enhancement of 11% in NO_x production. Addition of Ar and preheating of the feed resulted in lower NO_x production. Lower flow rates produced higher NO_x concentrations due to longer residence time in the GA. The volume covered by GA depends strongly on the gas flow rate, emphasizing that the gas flow rate has a major impact on the GA dynamics and the reaction kinetics. For 0.5 L/min, 1.4 vol % of NO_x concentration was realized, which is promising for a containerized process plant to produce fertilizer in remote locations. © 2017 American Institute of Chemical Engineers AIChE J, 2017

从空气中产生等离子体辅助的一氧化氮：使用脉冲动力滑弧反应器处理集装箱式工厂

NO的产生_X从空气和空气+ O ₂以脉冲供电毫规模滑动弧（GA）的反应器进行了研究，目的在于对化肥生产一个集装箱处理。研究了在不同比能输入下进料混合物，流速，温度以及Ar和O ₂含量的影响。这些发现与遗传算法动力学的高速成像相关。的O ₂的40-48％的含量为最佳，11％在NO增强_X生产。氩的加法和进料的预热导致较低的NO _X的产生。较低的流速产生更高的NO _X由于在GA中的停留时间较长，所以浓度较高。GA覆盖的体积在很大程度上取决于气体流速，强调气体流速对GA动力学和反应动力学具有重大影响。为0.5升/分钟，NO 1.4％（体积）_X浓度实现，这是有前途的一个集装箱处理厂以生产肥料在远程位置。©2017美国化学工程师学会AIChE J，2017
