摘　　要：研究软化点在评价煤沥青聚合程度中的作用,描述热聚合改质过程中煤沥青热解缩聚行为,并分析了中温煤沥青热聚合改质过程中各种沥青组分随热聚合温度和热聚合时间的转变规律。探讨QI组分影响煤沥青热聚合改质的机理,结果表明,原料煤沥青所含原生QI炭微粒促进了热聚合改质过程中煤沥青芳烃分子的聚合。The role of softening point in evaluating the polymerization degree of coal-tar pitch is investigated. The behavior of pyrolysis condensation of coal-tar pitch during the thermal polymerization modification is described. The conversion rules of coal-tar pitch components during the thermal polymerization modification are analyzed. The mechanism of action of the QI component on the modification of coal-tar pitch has been explored. It is found that the primary QI carbonaceous particles enhance the polymerization of aromatic hydrocarbon molecules during the thermal modification.
