摘　　要：用层流曳带流反应器对煤的快速热解规律进行了试验研究。探讨了煤种、热解终温、热解时间和反应器内煤粒的加热过程等因素对煤粉快速热解失重特性的影响．并对三种煤的热解挥发分组分析出规律进行了初步的研究。A reactor with entained flow is employed to study the fast pyrolysis characteristics ofpulverized coal.The effects of coal rank, pyrolysis temperature , pyrolysis time and partideheating on the overall weight loss are investigated. The volatile species evolution characteris-tics during fast pyrolysis is also examined. It is concluded that the temperature of the sec-ondary gas is an important factor that influences coal pyrolysis in the reactor and the specificvolatile species yields of different ranks of coal are quite different from each other.
