In this study, the effect of hydrogen on methane combustion characteristic was tested. The ignition temperature (T10) and burn off temperature (T90) was carried out in a quartz reactor at atmospheric pressure with the mixture flow rate of 800 mL/min. The compositions of outlet gas were measured online by Gasmet DX4000 FTIR gas analyzer. The results showed that hydrogen enhanced the activity of methane. For all methane concentration range, the T10 of methane could decrease 50 °C–70 °C with the H2/CH4 mole ratio at 0.1. For 1 vol.% methane combustion, when the H2/CH4 was equal to 0.05, the T10 and T90 could decrease 45 °C and 42 °C, respectively. When the H2/CH4 was 2.5, the T10 and T90 could decrease about 170 °C and 180 °C, respectively. Further more, CO generated in a wider temperature range when the hydrogen was added.
