One‐Pot Depolymerization, Demethylation, and Phenolation of Lignin for Bioactive Polyphenol Production

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
Low‐cost lignin was upgraded in an acidic lithium bromide (LiBr) solution via integrated depolymerization, demethylation, and phenolation to yield bioactive polyphenols with enhanced phenolic hydroxyl content. The resulting polyphenols exhibited strong antioxidant and antibacterial activities, along with low cytotoxicity and promising in vivo ...

Energetic and Exergetic Optimization of an Organosolv-Biorefinery Process

open access: yesChemical Engineering Transactions, 2012
In the present work the energy and exergy efficiency of an organosolv biorefinery process has been evaluated. Based on experimental data obtained from ethanol – organosolv fractionation, a lignocellulosic biorefinery has been designed and simulated with Aspen Plus in order to obtain mass and energy flows, thermodynamic properties of the streams and the

Precision Lignocellulosic Biorefinery: Process Regulation From Corn Stover to Products

open access: yesAdvanced Science, Volume 13, Issue 40, 17 July 2026.
This study presents a precision biorefinery framework that transforms corn stover into high‐value bioproducts through whole‐process regulation. Mechanical fractionation separates feedstock into parenchyma‐rich short fibers and vascular‐bundle‐dominant long fibers.

Production of Micro- and Nanoscale Lignin from Wheat Straw Using Different Precipitation Setups

open access: yesMolecules, 2018
Micro- and nanosize lignin has recently gained interest due to its improved properties compared to standard lignin available today. As the second most abundant biopolymer after cellulose, lignin is readily available but used for rather low-value ...

Prehydrolysis and organosolv delignification process for the recovery of hemicellulose and lignin from beech wood

open access: yes, 2022
Art. 100506Beechwood was fractionated using a two-stage process approach followed by enzymatic hydrolysis of the obtained pulp. Where most of the xylan was recovered by the prehydrolysis in the first stage, while the most lignin was recovered in the ...

UV-Vis Spectroscopy and Chemometrics for the Monitoring of Organosolv Pretreatments

open access: yesChemEngineering, 2018
Lignocellulosic agricultural side products like wheat straw are widely seen as an important contribution to a sustainable future economy. However, the optimization of biorefinery processes, especially the pretreatment step, is crucial for an economically

Lignin from Hardwood and Softwood Biomass as a Lubricating Additive to Ethylene Glycol

open access: yesMolecules, 2018
Ethylene glycol (EG)-based lubricant was prepared with dissolved organosolv lignin from birch wood (BL) and softwood (SL) biomass. The effects of different lignin types on the rheological, thermal, and tribological properties of the lignin/EG lubricants ...

PRODUCTION AND PROPERTIES OF OXIDATIVE-ORGANOSOLVENT

open access: yesJournal of Chemical Technology and Metallurgy
The article presents the results of research on the production of cellulose from non-wood plant raw material - Miscanthus giganteus stems - using the oxidative-organosolv pulping method. It was established that, in terms of the content of major components (cellulose and lignin), the raw material is comparable to wood, although it exhibits higher ash ...
