Microwave-assisted extraction of Camellia oleifera shell lignin via dual-acidic deep eutectic solvent and its mechanism.

Lignin represents a promising biomass resource for functional materials; however, its intricate structure poses significant challenges for efficient extraction. Herein, a novel dual-acidic deep eutectic solvent (DADES) composed of ZnCl and lactic acid (1:8 molar ratio) was developed, and which applied to facilitate the rapid extraction of lignin from waste Camellia oleifera shells (WCOS). Notably, this extraction process was significantly enhanced by microwave irradiation.

Fabrication of bimetallic RuCu/HAP catalysts for the selective synthesis of C biofuel precursors from biomass-based 5-methylfurfural.

The synthesis of bis(5-methylfuran)methane (BMFM) from biomass-based 5-methylfurfural (5-MF), a vital fuel precursor, is crucial for biomass refining. However, selective BMFM production from 5-MF needs to suppress side reactions such as hydrogenolysis and decarbonylation. Therefore, direct hydrogenation of 5-MF into BMFM is very challenging in sustainable biomass valorization.

Sequential hydrothermal liquefaction of lignocellulose-rich livestock manure: A new perspective on enhancing the production and quality of low-phenolic biocrude.

The treatment and valorization of bulk livestock manure rich in lignocellulose demand efficient processing techniques. Hydrothermal liquefaction (HTL) has emerged as a promising approach for waste-to-energy conversion, effectively transforming lignocellulosic biomass into renewable biocrude. However, the advances in the utilization of HTL-derived biocrude have been hindered by its poor oil quality due to several factors including high phenolic compound content.
