Abstract:

2,5-Dimethylfuran (DMF) is known as one of the potential biomass-derived liquid fuel and is of great significance to alleviate the current energy crisis. In view of its excellent property and wide application prospect, the preparation of DMF using biomass resources as raw materials through green and economic methods has gradually become a hot spot in scientific research. The recent advances in catalytic conversion of biomass carbohydrates into DMF at home and abroad are summarized in this paper. Based on the structure-activity relationship between the active center and the support, the catalytic effects of various metal catalysts are compared, and the key factors affecting the multiphase reaction system, including the different reaction routes and synthetic methods are analyzed. A highly efficient catalytic system for direct conversion of biomass carbohydrates into DMF is an important basis for technological breakthrough in the field. Some suggestions are given for further research and development to the catalytic conversion of biomass carbohydrates into DMF by one-pot reaction. In addition, it provides scientific basis and innovative ideas to explore efficient, economical, green and sustainable DMF synthetic pathway, which will guide the development of industrial technology for the catalytic conversion of biomass resources into DMF.
