The effect of CO, NO_2 and NO addition to methane-air mixture as well as the initial methane concentration upon methane oxidation at T=600℃-900℃ and P=1atm was studied experimentally using a flow reactor. Faster methane oxidation was observed for higher initial methane concentration. The addition of CO(0-1000ppm), NO_2(0-500ppm) and NO(0-500ppm) also enhanced methane oxidation. Higher level of CO and NO_2 addition resulted in higher methane oxidation ; however, existence of an optimum amount of NO addition to promote methane oxidation was observed. The optimum value was found to be dependent on the residence time. The experimental results were compared with three reaction mechanisms proposed by Amano and Dryer [9], Bendtsen et al. [5] and Bromly et al. [6].
