- 摘要：
- This paper describes an experimental study on the catalytic combustion of ventilation air methane in a
vertical reactor. The mixture of natural gas and compressed air was used in the experiments, and the
combustion products were analyzed by the Fourier transform infrared (FTIR) gas analyzer. The effects of
the initial temperature, cycle time, feed gas concentration, and space velocity were studied. The
experimental results show that the reactor could run under a wide range of operating conditions with
self-sustaining operation and high methane conversion. Besides, it could even run with a feed gas
concentration as low as 0.13 vol % without generation of CO and NOx, which has not been achieved in
previous studies. The optimization of operating parameter combination increases the stability and
efficiency of combustion. Different from the previous studies, the present research shows that the
temperature profile of the cyclic steady state is not affected by the initial temperature. In addition, the
methane conversion and reaction zone change during the process of the reaction. Thus, there is a limitation
about the employment of a gas chromatograph (GC) to measure the methane concentration. Moreover,
the presence of natural convection makes the temperature profiles of the cycle steady state asymmetrical.
