High-solid ethylenediamine pretreatment to fractionate new lignin streams from lignocellulosic biomass

Li Xu et al.

Summary: The study utilized a high-solid ethylenediamine pretreatment method to develop a new aminolignin with high aqueous solubility and minimal condensed structures. Unique amination reactions introduced hydrophilic amine and amide groups into lignin substructures, enhancing lignin processability. This solid-state EDA pretreatment holds promise for improving lignin's solubility and minimizing condensation, potentially advancing lignin-first biomass fractionation.

Organosolv fractionation of a lignocellulosic biomass feedstock using a pilot scale microwave-heating reactor

Yongjian Zhang et al.

Summary: A pilot scale microwave fractionation system (PMFS) was developed for the organosolv fractionation of bamboo sawdust. The PMFS achieved higher lignin and hemicellulose removal rates without serious cellulose degradation. The recovered lignin had a relatively narrow molecular weight distribution and the process showed good utilization efficiency of the bamboo feedstock.

Using microwave assisted organic acid treatment to separate cellulose fiber and lignin from kenaf bast

Wanwan Lv et al.

Summary: The research introduced a new clean fiber separation technology for kenaf bast, which showed higher lignin removal capacity and less damage to cellulose compared to the traditional sulfate method. Additionally, the new method significantly reduced processing time, energy loss, and waste liquid pollution. This study demonstrated that microwave-assisted lactic acid treatment could efficiently separate kenaf fibers with less damage and pollution.

Fractionation of Poplar Wood Using a Bifunctional Aromatic Acid under Mild Conditions

Duo He et al.

Summary: The study introduced a mild-condition fractionation process based on 4-Cl-BSA, which effectively extracted lignin, cellulose, and hemicellulose sugars from lignocellulose while maintaining their high quality. Results indicated that 4-Cl-BSA performed well in fractionating and preserving the beta-O-4 linkages and aromatic units of lignin.

Extraction of Noncondensed Lignin from Poplar Sawdusts with p-Toluenesulfonic Acid and Ethanol

Di Fan et al.

Summary: The novel extraction process using p-toluenesulfonic acid in ethanol successfully recovered 83.74% lignin yield from poplar sawdust, while retaining high amounts of cellulose and hemicelluloses. The major drivers of lignin condensation during fractionation were found to be acid concentration and extraction time. Ethanol reacted with lignin at the a-position to prevent the formation of condensed structures, leading to a promising yield of 50.35% of aromatic monomers during depolymerization over Pd/C catalysts.
