对神华煤加氢液化残渣依次使用正庚烷、甲苯、吡啶进行萃取,分别得到正庚烷可溶物(HS)、正庚烷不溶-甲苯可溶物(HI-TS)以及甲苯不溶-吡啶可溶物(TI-PS)3种可溶组分。分别以HI-TS及TI-PS两种组分为原料,采用直接热缩聚法,制备了中间相沥青(MP)。通过偏光显微镜、凝胶渗透色谱(GPC)等仪器分析手段对合成的中间相沥青进行了形貌及组成表征。实验结果表明:HI-TS组分在反应温度380℃,反应时间为6 h,TI-PS组分在反应温度380℃,反应时间4 h,均生成了光学组织结构好、中间相含量近100%的中间相沥青。

Shenhua coal hydro-liquefaction residue was extracted by n-heptane (H), toluene (T) and pyridine (P), successively, and the soluble fractions including HS, HI-TS and TI-PS were obtained. Mesophase pitches using HI-TS and TI-PS as the precursors were prepared by the direct heat polycondensation, respectively. The structure and properties of MP were analyzed by means of po-larization microscope and GPC. It was found that both HI-TS and TI-PS can produce mesophase pitches with fine optical texture and 100%anisotropic content.
