【 摘 要 】

Based on coal mine methane (CMM) emission policy in China and other main coal-mining countries in the world, a status quo of dilute methane (such as ventilation air methane (VAM) or similar concentration methane) reverse flow reactor (RFR) technology was looked back and the principal of the reverse flow reactor for dealing with dilute methane was introduced in detail. The development of the dilute methane RFR technology was carded and the main research directions and processes in this field were described, including reaction kinetics mechanism of dilute methane in the inert homogeneous channel, reaction heat front reverse movement rule in the RFR, numerical simulation of the RFR mathematical model, NOx emission of the RFR process, large-scale RFR experiments, and so on. The contradictions existed in the relative research of dilute methane RFR technology were discussed, and the evolution of the dilute methane RFR technology was predicted. And it would be necessary guidance for the scientific study, numerical simulation, optimization design and engineering application of the dilute methane RFR technology.
