Recent advances in biomass pretreatment using biphasic solvent systems

Abstract

The complexity and recalcitrance of lignocellulosic biomass seriously hinder’s its subsequent conversion to liquid fuels. To achieve high-value utilization of lignocellulosic biomass, the physical-chemical barrier should be overcome through appropriate...

Recent advances in hydrotropic solvent systems for lignocellulosic biomass utilization

“…[7][8][9] Biomass processing solvents including organic solvents, aqueous phase hydrotropes, and ionic liquids have been investigated to understand their effectiveness and fundamental mechanisms for biomass fractionation. [10][11][12][13][14][15][16][17][18][19][20][21] In addition to the technical performance of these solvents, their economic feasibility and environmental sustainability have been evaluated and considered in recent studies. 22,23 Despite many efforts in studying these solvent systems, many technical barriers remained to be overcome for commercialization.…”

Solvent-triggered directional lignin valorization towards monomeric acetals or lignin polyols

“…[16][17][18] The physical stabilization strategy, which involves the prompt separation of active reaction products, has shown great potential in controllable biorefinery. [19][20][21] The development of biphasic solvent systems plays a crucial role in enabling tailored lignocellulose fractionation, lignin extraction, and carbohydrate transformation processes. [22][23][24][25] For example, Chen et al provided a comprehensive overview of various biphasic solvent systems comprising organic solvents and water for biomass fractionation.…”

Sustainable preparation of oxidized graphitic material from wheat straw using a deep eutectic solvent for superactivity of cellulase

“…[20][21][22][23][24]25 Owing to their good solvation ability, DESs have been utilized in various processes such as biomass processing, organic synthesis, materials science, extraction and separation. 26 Considering these applications, Zhang et al, used a DES as a medium for preparing covalent organic framework (COF) materials with imine linkages. The copper metal was immobilized on COFs for enhancing photocatalytic applicability.…”
