摘　　要：介绍了煤焦油的来源、分类、组成、用途等,简述了当前煤焦油加工产业现状,详细分析了高温煤焦油和中低温煤焦油的主要加工工艺和研究进展。我国煤焦油加工产业已基本形成规模化效应,高温煤焦油深加工以高附加值产品提取为主;中低温煤焦油加工以加氢精制为主,产品提取为辅;分析认为燃料-润滑油-化工型路线是中低温煤焦油发展的重要方向。建议煤焦油深加工应进行规模化集中处理,开展综合利用,提高技术、装备水平,向精细化深加工方向快速发展。The source,classification,composition and application of coal tar were introduced,and the current status of coal tar processing industry was briefly described.The main processing technology and latest research progress of high temperature coal tar and medium and low temperature coal tar were analyzed in detail.China′s coal tar processing industry has basically formed a scale effect,the processing of high temperature coal tar mainly focused on extraction of products with high added value,and the processing of medium and low temperature coal tar was mainly hydrofining,with product extraction as auxiliary.It was pointed out that the fuel-lubricating oil-chemical route was an important direction for the development of medium and low temperature coal tar.It was suggested that coal tar deep processing should be carried out on a large scale and centralized treatment,implementing comprehensive utilization,improving technology level and equipment level,and developing rapidly towards refined deep processing.
