Computer modeling study of photochemical ozone formation in the propene-nitrogen oxides-dry air system. Generalized maximum ozone isopleth

Computer simulation for the propene-nitrogen oxides-dry air system was performed by using a detailed reaction model in order to represent previous experimental results. The proportional relationships between (0/sub 3/)/sub max/ and (0/sub 3/)/sub ps/, (NO/sub x/)/sub 0//sup 1///sup 2/, and K/sub 1//sup 1///sup 2/ were sucessfully reproduced by the model. Based on the calculated data, the plot of (0/sub 3/)/sub max//(0/sub 3/)/sub ps/ vs. (C/sub 3/H/sub 6/)/sub 0//(NO/sub x/)/sub 0/ was found to fall on a single common curve, which is called a generalized maximum ozone isopleth. In the falloff region of the above plot, an approximate linear relationship between (0/sub 3/)/sub max//(0/sub 3/)/sub ps/ and ((C/sub 3/H/sub 6/)/sub 0//(NO/sub x/)/sub 0/)/sup 1///sup 2/ was obtained, implying that (0/sub 3/)/sub max/ is linear with (C/sub 3/H/sub 6/)/sub 0//sup 1///sup 2/ in the NO/sub x/-excess region.
