【Abstract】 The composition and source of lower molecular weight compounds in coal and several chemical structure models of coal were introduced. The main methods involved in the study of lower molecular weight compounds were reviewed, including the mild solvent extraction and organic spectroscopy. The compounds, dissociated or enchased in the skeleton structures of coal macromolecular, have remarkable effects on the conversion behavior of coal such as coking property, liquefaction and many others.更多还原
