摘要
综述了 CS2 /NMP混合溶剂用于煤抽提的研究进展 ,着重介绍了煤阶、煤岩组分、添加物和各种辅助手段对抽提率的影响 ,并对添加物的增溶机理、混合溶剂的抽提机理、抽提动力学以及抽提物的表征等问题进行了讨论 ,指出高抽提率的溶剂抽提不仅对于煤结构的研究有着重要的意义 。
This paper reviews the advances in coal extraction with carbon disulfide / N methyl 2 pyrrolidinone mixed solvent.Mainly introduces some factors that affect the extraction yields such as coal rank,macerals,additives and various auxiliary methods.The mechanism of the increasing solubilities by the additives,the mechanism and kinetic of coal mixed solvent extraction and the determination of extraction fractions are discussed as well.Based on the high extraction yields of CS 2/NMP mixed solvent,it is not only of great importance to investigate coal structure,but also possible to be a new approach to obtain high value added chemical products and clean coals.
