Abstract：Oxidation of coal mine ventilation air methane ( VAM) was investigated in a thermal reverse-flow reactor. The effects of CH_4 concentration, flow, cyclic period and temperature were studied. The results show that oxidation of coal mine ventilation air methane is achieved for methane concentration of 0. 2% ～ 0. 8% in reactor. The conversion rates of CH_4 are all above 99% , and some heat can be recovered. With the increase of CH_4 concentration and flow, temperature of middle area increases, volume of high temperature increases. It is to improve conversion rate of CH_4. The optimum window of cyclic period is 90 ～150 s. The lowest oxidation temperature is 880℃.
