摘　　要：煤基沥青的加工和利用对于煤焦油工业加工非常重要,简单介绍了煤基沥青改质要求,着重介绍了5种煤沥青改质工艺的研究进展,分别为氧化法、热聚合法、加压热聚处理法、C-T法、减压热聚法,并对其改进后煤沥青质量方面的指标进行了对比,为今后煤基沥青改质工艺发展提供了方向。煤基沥青改质对于煤液化工艺及其煤焦油加工方面具有非常重要的意义。The processing and utilization of coal tar pitch are very important for the processing of coal tar pitch. Therequirements of modified coal tar pitch were briefly introduced. There were five kinds of coal tar pitch modificationprocesses to be introduced, such as oxidation method, thermal polymerization method, heat treatment method, CT methodand vacuum thermal polymerization method. The modified quality indicators of coal tar pitch were compared. It providedthe direction for the future development of coal tar pitch modification technology. It is very important for the modificationof coal tar pitch to coal liquefaction process and coal tar processing.
