Abstract

The influence of the reaction temperature, inlet oxygen/ammonia ratio, and W/F on the oxidation of ammonia over various transition metal oxides was investigated by flow technique. Activity for the oxidation of ammonia was found to be limited by the oxidation power of catalyst; a close relationship was obtained between the activity and the width of forbidden band of the oxides. On the other hand, the selectivity of the reaction was shown to be mainly determined by the activity of the catalyst for NO-NH3 reaction. A model for the reaction paths of the oxidation of ammonia which include NO-NH3, NO-O2, and NO2-NH3 reactions was proposed on the basis of the experimental results.
