چکیده
|
In this research, small molecular compounds are extracted from shenfu coal using solvent extraction method, then through analysis and comparison the structure and properties of coal before and after extraction of coal in order to study small molecular compounds affect the structure and properties of coal. the results show that they have been affected to varying degrees and the core of the coal structural unit aromatic ring has not been reduced, the macromolecular structure of coal has not changed after the extraction of coal. and these studies surely help to study the reaction mechanism of coal liquefaction and guide the study of coal macromolecular.
