The removal of extremely low concentration substances under microwave non-steady state irradiation was investigated more deeply about NO among ethylene, ammonia, and nitric oxide(NO)those were investigated in previous year.When the mixture of copper oxide and cobalt oxide was used as a catalyst, existence of the effect of not only mere heating effect but also non-heating effect by electronica activation of surface was suggested.Regarding the removal of extremely low concentration CO in high concentration hydrogen using a quasi-moving bed chemical reactor, it was found that the generation and movement of a reaction front was decided by the ratio of the carbon monoxide feed rate to that of oxygen.Namely, it was found that by controlling each ratio well, to minimize the loss of hydrogen and maximize the removal rate of CO. Furthermore, it was strongly suggested that the mechanism of the carbon monoxide oxidation reaction at 100℃ on the platinun support alumina catalyst used by this research was not the Langmuir-Hinshelwood’s mechanisem but the Eley-Rideal mechanism. The simulation based on this reaction mechanism was performed.

对前年研究的乙烯、氨、一氧化氮（NO）中的NO，微波非稳态辐照下极低浓度物质的去除进行了更深入的研究。当使用氧化铜和氧化钴的混合物作为提出了通过表面电子活化不仅存在单纯的加热效应而且还存在非加热效应的催化剂。关于使用准移动床化学品去除高浓度氢气中的极低浓度CO研究发现，反应前沿的产生和移动取决于一氧化碳进料速率与氧气进料速率的比率。即，发现通过控制好各个比率，可以最大限度地减少氢气的损失并最大化此外，强烈表明本研究使用的铂载体氧化铝催化剂上100℃一氧化碳氧化反应的机理不是Langmuir-Hinshelwood机理但基于该反应机理进行了Eley-Rideal机理的模拟。
