Abstract: | The reduction of nitric oxide by reaction with non-hydrocarbon fuels under reducing conditions at comparatively higher temperature
has been studied with a detailed chemical kinetic model. The reaction mechanism consists of 337 elementary reactions between
65 chemical species based on the newest rate coefficients. The experimental data were adopted from previous work. Analyses
by comparing existing experimental data with the modeling predictions of this kinetic mechanism indicate that, at comparatively
high temperature, apart from the reaction path NO→HNO→NH→N2, NO+N→N2 is also prominent. In the presence of CO, NO is partly converted to N by reaction with CO. Based on present model, the reduction
of NO at high temperature, which was usually underestimated by previous work, can be improved to some extent.
This work was presented at the 7
