煤焦油沥青加工应用的研究进展

摘要

Coal tar pitch is the residue after extraction of the light components from coal tar. The research of modified coal tar pitch has been continuously developing due to more stable performance, higher carbon content and lower price. In this paper, characteristics and composition of coal tar pitch were summarized. And main application of modified coal tar pitch in carbon products, graphite electrode, needle coke, mesophase pitch, carbon fiber, paint and fuel oil was introduced.%　　煤焦油沥青是把煤焦油中的轻质组分提取后剩余的残渣，由于其性能相对比较稳定，煤焦油的碳含量高，价格低廉，所以煤焦油改质沥青的研究得到了不断的发展；概述了煤焦油沥青的性质和组成；总结了改质沥青在碳素制品、石墨电极、针状焦、中间相、碳纤维、涂料和燃料油等领域的应用。
