| Abstract: | 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. |
