摘　　要：煤层气作为一种非常规天然气,既是宝贵的清洁能源,其主要成分甲烷同时也是一种主要的温室气体;煤层气的直接排放不仅加剧了大气温室效应和环境污染,同时也是能源资源的极大浪费。近年来,煤层气的治理和利用受到了广泛关注,有关技术研究和开发取得了很大进展。本文对近年来煤层气的治理和利用技术研发进展进行了总结和评估,侧重于介绍煤层气分离系统中关键的中、高浓度煤层气催化燃烧脱氧技术以及乏风瓦斯逆向流催化燃烧减排及余热利用技术。最后对煤层气综合利用技术进行了展望。Coal bed methane（CBM） as an unconventional natural gas is a valuable energy resources;meanwhile the main content of CBM,methane,is also one of the most important gases that contribute towards inducing the greenhouse effect.The mitigation and utilization of coal bed methane,by reducing methane emissions and producing energy from recovered methane,can offer both opportunities to mitigate global climate change and to generate new sources of clean energy,which is therefore of great significance in both economic and environmental aspects and has received extensive attentions in recent years.In this paper,we attempt to make a review on the recent progresses of research and development in the mitigation and utilization of CBM.We focused mainly on the application of catalytic combustion in CBM mitigation and utilization,especially the deoxygenation of oxygen-bearing CBM,which is the key issue for methane concentration through pressure swing adsorption,as well as the mitigation and heat recovery of ventilation air methane（VAM） by using catalytic flow reversal reactor.Lastly,we would have an outlook on the possible technologies for the integrated utilization of CBM.
