摘要： 报道一种不用催化剂,一步脱除NO的新方法--常压微波放电法。探讨在(NO,He),(NO.O2,He)和(NO,O2,H2O,He)体系中微波放电脱除NO的差异。研究结果表明,在(NO,He)条件下可实现一步高效脱除NO,在(NO,O2,He)条件下也可实现80%左右的NO转化,其中N2的选择性高达80%,而H2O的加入并未影响N2的产率。同时发现,随着微波功率的加大,NO转化率也增大,而N2的选择性增大得更多。最终可达到一个平衡值。最后研究了NO和O2浓度及气体流量对NO脱除的影响。

Abstract: The decomposition of NO in a continuous microwave discharge was investigated.When(NO,He) mixture was used as the reactant, almost all NOcan be converted to N2.In(NO, O2 ) He) system,the conversion of NO was nearly 80%, and the selectivity of N2 was 80%.When adding 5% H2O to(NO,O2, He) system, the productivity of N2 was not changed basically.However, as the microwave power wasincreased, the conversion of NO increased, and the selectivity of N2 increased even more.The effects ofNOand O2 concentrations, and flow-rate on NO removal were also observed in the microwave discharge.

Key words: Microwave discharge, NO removal, Selectivity of N2, Microwave power
