强电场放电常压合成NH_3研究

Study on synthesis NH_3 at normal pressure by the strong electric field discharge

应用超强窄脉冲电场在整个反应器内形成的强烈流光放电，在常压条件下使Ｎ２，Ｈ２发生电离、分解反应，产生大量的自由原子、离子、自由基等，形成非平衡等离子体，在定向化学合成反应模型的控制下合成了ＮＨ３，合成ＮＨ３浓度可达５０００ μＬ／Ｌ．

A violent streamer discharge produced by ultra-strong narrow pulse electric field in the whole reactor, makes N,, H_2 ionize and dissociate to transform a large number of free atoms, ions, radicals and so on. At the same time, the non-equilibrium plasma is formed at the normal pressure. With this method, NH, gases are synthesized under the control of a di- rectional chemical reaction model, which concentration can reach 5 000uL/L.
