摘　　要：本文利用气流床快速热解装置,在常压氮气气氛下,考察了东胜、神府和小龙潭煤的热解焦性质。结果表明,随着热解终温的升高,气相产率增加,液相产率存在一最大值,固相产率均大于50%。气化速率与煤化程度、碱金属离子含量及孔隙结构有关。The pyrolytic coke properties of coals from Dongsheng, Shenfu and Xiao- longtan coal mines have been studied in the paper at the atmosphere of normal pressure ni- trogen by means of airflow bed rapid pyrolytic system. The results obtained from the study show that the gas phase yield is increased with the rise of final pyrolytic temperature, while the liquid phase yield exists at a max, value, all the solid phase yields are more than 50%. The gasification rate is correlated with coalification, content of alkali metallic ion and porous structure.
