摘要

In the field of biomass refining, efficient utilization of lignocellulosic biomass has always been a crucial research direction, with the challenging processing difficulty stemming from the compactness of its structure. As novel "green" solvent, deep eutectic solvents (DESs) have demonstrated immense potential in the pretreatment process of lignocellulosic biomass due to their remarkable advantages such as low melting points, excellent solubility, environmental friendliness, biodegradability, and ease of recycling and reuse. This article delves into the diverse types and unique physicochemical properties of DESs, and analyzes their roles and mechanisms in the pretreatment of lignocellulosic biomass. Additionally, it summarizes the issues surrounding the recycling and reuse of DESs. While DESs exhibit significant advantages in the pretreatment process of lignocellulosic biomass, there are still some existing problems and challenges. This article not only identifies these issues but also proposes corresponding improvement measures and future prospects, aiming to promote the further development and application of DESs in the field of biomass refining.
