| 摘 要： | 以三种高挥发分烟煤为原料,对固体热载体煤热解获得的气、油、焦产物产率、组成和性质进行了考察.结果表明,提高煤与热载体的混合热解温度可使煤气和焦油产率有所增加.热解焦油产率可达干煤重量的9%～11%,热解焦油可用于提取具有较高附加值的BTX,PCX,萘及脂肪族烃类等产品.热天平燃烧实验结果显示,热解半焦仍具有很好的着火和燃烧特性,随着热解反应温度的提高,燃烧区间向高温区移动,确定了半焦燃烧的反应动力学及其参数.

| Abstract: | Three high volatile bituminous coals were used pyrolysis with solid heat carrier to investigate the product distribution and characteristic of gas, tar and char. The results show that the yield of gas increases with pyrolysis temperature. Tar yield from three coals is 9%-11%. PCX takes about 10% of the pyrolysis tar. The ignition, burnout characteristics and activation energy of the three coals and their pyrolysis char were studied by thermogravimetric analysis. Pyrolysis char shows good combustion characteristic and the kindling point of char increases with the increased pyrolysis temperature. The kinetics parameters of char combustion were calculated and compared. |
