Abstract
The simultaneous evolution of CO, CO2, N2O, and NO, detected and estimated by both infrared spectroscopy and chemiluminescence during the reaction of soot and NO2/N2O4 over a range of temperatures, suggests that, in addition to the previously described chemisorption reaction, there also is a redox process occurring in the initial stages of the reaction. Estimations of these gases suggest that the redox reaction also includes reactive components other than the olefinic segment of soot, and occurs under all conditions examined. Infrared studies show that gaseous NO, produced immediately on the introduction of NO2/N2O4 into a reactor containing soot and water vapor, subsequently decreases with the accompanying formation of N2O.Keywords
