An experimental study of the oxidation of pyrrole in the absence and in the presence of NO has been performed. The experiments were conducted in an isothermal quartz flow reactor at atmospheric pressure in the temperature range 700 1500 K. The influence of the temperature, air excess ratio (corresponding to rich, stoichionnetric, and lean conditions), and presence of NO on the concentrations of CO, CO2, HCN, and NO has been analyzed. The present work, which corresponds to the global objective of studying the conversion of volatile nitrogen compounds, contributes to it with results related to pyrrole that contribute to extend the experimental database on the conversion of nitrogen volatile compounds. Also, a preliminary reaction mechanism based on various literature mechanisms has been used for simulating the experimental results.
