Kinetic Modeling of the Gas-Phase Oxidation of Nitric Oxide Using Hydrogen Peroxide
Publication: Journal of Environmental Engineering
Volume 131, Issue 4
Abstract
The use of hydrogen peroxide to enhance the oxidation of nitric oxide (NO) under postflame conditions in the presence or absence of sulfur dioxide has been studied by means of chemical kinetic modeling and compared with pilot-scale experimental data. The experimental results were obtained from a nonisothermal reactor at atmospheric pressure with inlet temperatures in the range of . The CHEMKIN-II model with a kinetic mechanism from the literature was employed for this work. At the temperatures studied, produces OH and radicals which enhance the oxidation of NO. The OH radical also helps oxidize . The modeling results confirmed an optimum temperature of about where the NO conversion reached about 90% with an molar ratio of 1:1. Conversion of to was found to occur to a slight extent. Finally, the presence of was found to promote slightly the oxidation of NO to .
