To further elucidate the advantageous effects of hot-water extraction (HWE) on delignification, milled wood lignin (MWL … lamella (ML) and the secondary wall (SW), respectively. The cleavage of dibenzodioxocin (DB) and spirodienone (SD) lignin … substructures during HWE is suggested. The removal of lignin during acetone:water (AW) extraction of hot-water extracted wood …

In this study, we determined the content of lignin, cellulose …, holocellulose, and extractives, syringyl to guaiacyl (S/G) ratio in lignin, and also calculated higher heating values (HHV) among … eight examined clones of <i>Populus</i> grown on three different experimental sites. The highest lignin content for all the …

Here, a novel and efficient base-catalyzed depolymerization and in situ hydrogenolysis … process for lignin decomposition and char elimination was proposed using the synergic catalyst of NaOH coordinated with Ru …/C. In which, lignin was first depolymerized to phenolic monomer and its oligomer, and then the oligomer was further …

Herein, α-cellulose, d-xylose, and lignin, which are major lignocellulosic biomass constituents, are subject to being …% with an increase in temperature from 265 to 350 °C, while the yields of biocrudes obtained from lignin (25.2–28.8 wt%) and …
