Biomass-based ester compound fuel and preparation method thereof

The invention discloses a biomass-based ester compound fuel and a preparation method thereof, alkyl glucoside is used as a raw material, an acidified mesoporous carbon material is used for catalyzing one-step conversion to prepare levulinic acid ester and formate, the levulinic acid ester and the formate are directly used as fuel additives, separation and purification steps are not needed, formate byproducts do not need to be removed from the levulinic acid ester, and the biomass-based ester compound fuel is prepared. Furthermore, the utilization rate of the raw materials is increased, the preparation cost is reduced, diesel oil is partially replaced, and the energy structure is improved. 本发明公开了一种生物质基酯类复配燃料及其制备方法，以烷基葡萄糖苷为原料，用酸化介孔碳材料催化一步转化制备乙酰丙酸酯和甲酸酯，直接做为燃料添加剂使用，无需进行分离提纯步骤，无需从乙酰丙酸酯中除去甲酸酯副产物，进而提高了原料的利用率，进而降低制备成本，并以部分替代柴油，改善能源结构。
