| 摘 要： | 以正己烷为溶剂,考察了热溶温度对红柳林煤（HL）热溶行为的影响,并研究了不同热溶温度下残渣的热解特性。结果表明：随着热溶温度从260℃升高至340℃,热溶萃取的小分子化合物（包括焦油和水的液相产物以及气相产物）的产率逐渐从7.10%增加至11.96%。热溶处理对原煤热解行为的影响显著,经过热溶处理后原煤热解析出的挥发分的产率则从28.02%降至10.49%~21.38%。随着热溶温度从260℃升高至340℃,热溶残渣热解过程中析出物质的产率从21.38%降至10.49%,液相产物的产率从12.01%降至3.72%,气相产物的产率稍有降低。煤中的小分子化合物是煤低温热解过程的"活性"物质,它不仅是化合物热解液相产物的组成部分,还可为煤的主体结构热解供氢,促进煤热解向焦油和气体的转化。
