电辅助有机溶剂预处理木质纤维素高效分馏与价值化路径的绿色革新

Electro-assisted organosolv pretreatment (EAOP) is recognized as an emerging environmentally friendly pretreatment technology that integrates electrochemical processes with organosolv systems to achieve efficient and selective separation of the primary components (cellulose, hemicellulose, and lignin) of lignocellulosic biomass under mild conditions. The fundamental principles and core advantages of EAOP technology were introduced, and recent research progress in its application for lignocellulosic biomass pretreatment was reviewed, with particular emphasis placed on key breakthroughs such as innovations in solvent systems (e.g., ionic liquid/γ-valerolactone systems) and process intensification mechanisms. The role of EAOP on enhancing enzymatic saccharification efficiency and promoting the valorization of all biomass components was also evaluated. Furthermore, the economic feasibility and industrialization challenges hindering the large-scale application of EAOP were analyzed, aiming to offer valuable insights for further development and industrial implementation of this technology.
