摘要研究了低温等离子体去除氮氧化物的方法。为了提高高去除率和能量效率，实验研究了催化剂与低温等离子体的组合过程。在真实的废气含有不完全燃烧的碳氢化合物的情况下添加碳氢化合物。然而，沸石催化剂在室温下表现出NOx吸附。为了减少NOx在催化剂表面的吸附，开发了一种内部具有网状电极和介质阻挡层的板式反应器。通过测定NO或NOx浓度的时间依赖性，研究了沸石催化剂的吸附特性。在这些实验中几乎没有观察到它们，因为与线-筒反应器相比，催化剂的量非常小（4-5%）。
Abstract Non-thermal plasma has been studied to remove nitrogen oxides. In order to improve both high removal and energy efficiency, the combined process of the catalyst with the non-thermal plasma was examined experimentally. Hydrocarbons were added where real exhaust gas contains hydrocarbons from incomplete combustion. However zeolite catalysts have shown NOx adsorption at room temperature. For decreasing the NOx adsorption on the catalyst surface, a plate type reactor, which has mesh electrodes and dielectric barriers inside, has been developed. Adsorption characteristics of zeolite catalyst were investigated by measuring time dependence of NO or NOx concentrations. They were hardly observed in these experiments, since, quantities of catalyst were very small (4-5%) compared to that of wire-cylinder reactor.
