摘　　要：低阶煤的高效利用是近年来煤化工工作者研究的重点方向之一。本文综述了索氏萃取、超声辅助萃取、微波辅助萃取、化学处理辅助萃取和热萃取等溶剂萃取技术在低阶煤组成结构和转化研究中的应用。最后指出随着萃取技术的发展,可望从分子水平上揭示低阶煤的组成结构特征,从而实现其高效洁净转化。Effective utilization of low rank coals was one of the most important research topics. The recent progress of solvent extraction technologies, such as soxhlet extraction, ultrasound- assisted extraction, microwave -assisted extraction, chemical treatment assisted extraction, and thermal extraction, etc. used in the studies of the composition and structural characteristics, and effective utilization of low rank coals was reviewed. With the development of extraction technology, it was impossible to identify the composition and structural characteristics of low rank coals from molecular level, and utilize them effectively.
