【Abstract】 The structure of asphaltenes determines its chemical properties and application pathways, and the understanding of its formation rules and structure control is the basis for the efficient utilization of asphaltenes. Therefore,the source,separation and characterization,structural properties and applications of asphaltenes were discussed,and the different characterization methods for asphaltene structure analysis were compared. The research on coal-based asphaltenes had practical significance for optimizing the economics of the entire coal liquefaction process,improving resource utilization,and deeply understanding complex coal molecular structures.更多还原
