摘要
介绍了褐煤的溶剂萃取研究状况,包括褐煤的组成特征,萃取剂的选取原则,不同萃取溶剂和不同溶剂萃取方式等得到的褐煤萃取效果,并对褐煤溶剂萃取研究进行了总结,指出目前褐煤溶剂萃取研究还停留在实验室研究阶段,距离工业应用还有很大距离。
The study situation of lignite extraction with solvent,including the composition features of lignite,selecting principle for extracting solvent is described,and the results of lignite extraction are obtained with different extracting solvents and different extraction modes etc.The study on the lignite extraction with solvent is summed up.It is pointed out that the present study on lignite extraction with solvent is still in the stage of laboratory study and there is long way to go for industrial application.
