摘　　要：以陕西神府煤(SF)、新疆广汇煤(GH)和内蒙古贺斯格乌拉煤(HSG)为对象,采用了基于程序升温法的固定床热解装置,研究了热解终温对热解气体组成的影响。实验结果表明,随着热解终温的升高,煤热解气体产物产率越大;煤的煤化程度越高,热解气体中低碳烃类产物越少;煤热解气中的CO、CO_2含量取决于煤中O/C。The effect of the final pyrolysis temperature of three coal, as ShenFu coal from Shaanxi （SF）, GuanHui coal from Xinjiang （GH） and HeSiGeWuLa coal from Inner Mongolia （HSG）, on the composition of the pyrolysis gas was studied with temperature programming method in fixed bed reactor. The results showed that the yield of pyrolysis gas was higher with the increase of pyrolysis temperature. The higher the coal degree of coal was, the less the yield of the low carbon hydrocarbon in pyrolysis gas was. The content of CO and CO2 in coal pyrolysis depends on O/C in coal.
