Effect of Carbon Monoxide on Photochemical Reaction (I)

Abstract

In our previous report, the authors described an experimental study on the influence of carbon monoxide on nitric oxide oxidation and hydrocarbon consumption in photochemical reaction. The estimation of the effect of carbon monoxide on photochemical reaction has been made by a photochemical model in this paper. When the ratio of CO/HC is high and the reactivity of hydrocarbon is low, nitric oxide oxidation and the formation of nitrogen dioxide and ozone are accelerated by carbon monoxide. However, the decrease of hydrocarbon is controlled to the contrary. The result of our study shows good agreement with experimental data obtained previously by the others.
