摘要

为了评估仅使用微波而不进行级联处理（例如电子束或化学反应物）是否可以减少柴油发动机废气中的氮氧化物，开发了一种概念验证微波非热等离子体反应器（NTPR）。实验研究采用2.47 GHz的10和5 kW源驱动基于波导的腔，实现了22.6 dB的放大增益。脉冲微波气体处理证明，通过使用最佳的脉冲持续时间和脉冲重复率对，可以减少氮氧化物。通过使用不同占空比的脉冲方案，进一步提高了氮氧化物还原效率。

Diesel Engine Exhaust Gas Treatment for NOx Reduction Using Microwave Nonthermal Plasma Reactor

A proof of concept microwave non-thermal plasma reactor (NTPR) has been developed in order to assess whether the sole use of microwaves without cascading treatment, for example, electron beam or chemical reactants, may reduce NO_x in diesel engine exhaust gas. The experimental study used a 2.47 GHz source at 10 and 5 kW to drive a waveguide-based cavity achieving an amplification gain of 22.6 dB. Gas treatment with pulsed microwaves proved that NO_x reduction is possible by using optimal pairs of pulse durations and pulse repetition rates. Further improvements on the NO_x reduction efficiency were achieved by using a varying duty cycle pulsed scheme.
