摘　　要：煤二氧化碳气化反应是一种煤清洁利用的手段,其关键是提高反应活性。综述了原煤性质、热解过程、反应温度与压力、催化剂,以及二氧化碳气速、煤焦的粒度等因素对反应活性的影响,并对煤焦气化技术进行了展望。Gasification reaction of coal char with carbon dioxide can be a new route for cleaner utilization of coal. The key of this reaction is to improve the reactivity. The influences of raw coal characteristics, pyrolysis process, reaction temperature, reaction pressure, catalyst, carbon dioxide velocity and size of coal char on activity are reviewed. The prospect on coal char gasification technology is also viewed.
