Resumen: In the present work, experimental results from the literature on the effect of CO on the NH oxidation in the absence and presence of NO are supplemented with novel flow reactor results and interpreted in terms of a detailed chemical kinetic model. The kinetic model provides a satisfactory prediction over a wide range of conditions for oxidation in flow reactors and for flame speeds of CO/NH. With increasing levels of CO, the generation of chain carriers gradually shifts from being controlled by the amine reaction subset to being dominated by the oxidation chemistry of CO, facilitating reaction at lower temperatures. At elevated temperature, presence of CO causes a change in selectivity of NH oxidation from N to NO. The present work provides a thorough evaluation of the amine subset of the reaction mechanism for the investigated conditions and offers a kinetic model that reliably can be used for post-flame oxidation modeling in engines and gas turbines fueled by ammonia with a hydrocarbon or alcohol as co-fuel.
