Abstract: The origin, properties and composition of coal tar residue(CTR)are introduced. CTR poses serious threats to the environment. Coal tar residue treatment technology mainly includes oil recovery and resource utilization. The research progress of CTR treatment technology is reviewed. Treatment methods of coal tar residue are compared and summed up. No single specific process can be considered as the best, since each method is associated with advantages and limitations. Centrifugation treatment should work with other methods to achieve more efficient separation. Coal blending and use as fuel can not be fully utilized. Ionic liquids as green solvents will become a research hot spot in the field of separation. Preparation of high value added chemicals from CTR by modification and treatment has attracted more attention. More effective treatment performance might be achieved by integrating different methods into a process train. Comprehensive examination of CTR treatment methods will provide good understanding of recent developments and future research directions.

Key words: coal tar residue, coal chemical industry, gasification, coking, recovery

摘要: 介绍了不同煤焦油渣的来源、产生的原因、主要组成、基本性质以及因大量堆放对周围环境造成的严重影响。分析了国内外、特别是国内学者对煤焦油渣的处理技术, 主要有油、渣分离和进行资源化的开发利用, 同时对煤焦油渣处理技术的研究进展进行重点概述。最后对各种处理技术方法进行总结, 得出每种方法的优点和局限性, 其中机械分离需要结合其他方法才能达到较好效果, 配煤和作燃料用都未能得到充分的利用, 离子液体萃取将成为溶剂萃取的新方向, 而将煤焦油渣通过改性、处理等制备高附加值材料得到越来越多的研究, 并提出了多种技术的组合比单一的技术可能得到更加有效的处理效果。最后指出本文在一定程度上有助于更好地了解煤焦油渣处理的近期发展和未来的研究方向。
