采用傅里叶红外光谱(FT-IR)分析了热聚合改性和添加无烟煤热聚合改性中温煤沥青的组分结构变化；采用综合热分析仪(TG-DTG)研究了热聚合改性和添加无烟煤热聚合改性中温煤沥青的热解缩聚特征；采用气相色谱质谱联用(GC-MS)等技术初步探讨了煤沥青热聚合改性机理。研究结果表明：无烟煤热聚合改性的中温煤沥青，芳香度明显提高；无烟煤促进了中温煤沥青热处理过程中缩聚反应的进行。

The structural compositions and group changes before and after the thermal polymerization modification and the thermal polymerization modification with anthracite were investigated with FT-IR spectroscopy.The pyrolysis and polycondensation characteristics of the coal-tar pitch before and after the modification were studied with TG-DTG.And then,the modified mechanism was discussed by using Gas Chromatography-Mass Spectrometer method (GC-MS).The results showed that the aromaticity of the modified coal-tar pitch with anthracite modifier increased significantly.Anthracite promoted the polycon-densation reaction in the process of heat treatment of the medium temperature coal tar pitch.
