离子液体预处理木质纤维的研究进展OA

As a recyclable and renewable biomass,the efficient utilization of lignocellulosic was of great significance to solve energy shortage and environmental problems.Ionic liquid pretreatment had emerged as a key technology for lignocellulosic biomass refining,due to its selective dissolution,low volatility and recyclability.This paper systematically reviewed the structural characteristics of lignocellulose and provided an in-depth comparison of technical features and limitations of pretreatment methods,such as physical,chemical,biological,and physicochemical approaches.It focused on analyzing the principles and classification of ionic liquid pretreatment for lignocellulose,along with key influencing factors such as acidity/alkalinity,concentration,water content,temperature,and time.Furthermore,it explored the universality and specificity of this pretreatment method.In addition,this paper summarized strategies for developing low-cost ionic liquids and methods for process optimization.Finally,the toxicity issues of ionic liquids and their impact on the pretreatment process were objectively evaluated,and future development directions were outlooked:developing low-cost,low-toxicity,high-stability ionic liquid systems,deepening structure-activity relationship research,advancing continuous and integrated process development,and achieving high-value utilization and industrial application of lignocellulosic biomass.
