摘　　要：煤焦油沥青的深加工对提高煤焦油沥青利用价值和经济性至关重要。本文主要概述了煤焦油沥青深加工利用的主要技术,重点概述了球形活性炭、中间相沥青、通用级沥青基碳纤维以及针状焦等。对各种产品的关键技术进行了分析,介绍了当前在各项关键技术方面的研究进展。煤焦油沥青基球形活性炭、通用级沥青基碳纤维以及针状焦已经得到了比较广泛的应用,当前研究的难点是提高各项产品的品质,缩短加工周期。另外,中间相沥青的发现与应用拓展了传统碳材料的应用领域,并大幅提高了炭材料的相关性能。The improvement in the further processing of coal tar pitch（CTP）is essential to increase its added value. This paper has summarized several techniques for further processing of CTP,with the focus on the preparations of spherical activated carbon,mesophase pitch,carbon fiber,needle coke and so on. We also analyzed the key techniques for several products and introduced progress of those key techniques. Coal tar pitch based spherical activated carbon,general grade carbon fiber and needle coke have been utilized commonly. The difficulty of current research is how to improve the products’ quality and shorten the process time. Besides,the discovery and application of mesophase pitch has expanded the utilization field of traditional carbon material,and enhanced the related performance substantially.
