“…Biomass, as the carrier of bioenergy, has a low calorific value for direct use and usually needs to be converted into high-grade products to improve performance before use. Standard conversion methods of biomass include liquefaction, pyrolysis, and gasification [9][10][11]. Among them, liquefaction or solvent liquefaction is the process by which the biomass is processed for a period of time to decompose the solid biopolymer structure into the main liquid components [12].…”

Liquefaction conversion technology has become one of the hottest biomass conversion methods due to its flexible material selection and extensive product applications. Exploring biomass liquefaction conversion focuses on catalysts, biomass/water ratio, and reaction temperature. However, it is found that solvents are crucial in the biomass liquefaction process and significantly impact the type of liquefied products and bio-oil yield. Given the current rapid development trend, timely sorting and summary of the solvent effect in the biomass liquefaction process can promote the subsequent development and industrialization of more efficient and cleaner biomass liquefaction technology. Therefore, this review first introduces the characteristics of water as the liquefaction solvent, then summarizes the effects of organic solvents on liquefaction, and finally elaborates on the synergistic effect of co-solvents, which provides a more systematic overview of solvent effects in the liquefaction process. Meanwhile, prospects are put forward for the future development of biomass liquefaction conversion.
