Lignin, as a precious resource given to mankind by nature with abundant functional aromatic
structures, has drawn much attention in the recent decade from academia to industry …

Lignin is an abundant renewable macromolecular material in nature, and degradation of
lignin to improve its hydroxyl content is the key to its efficient use. Alkali lignin (AL) was …

More efficient use of lignin carbon is necessary for carbon-efficient utilization of
lignocellulosic biomass. Conversion of lignin into valuable aromatic compounds requires the …

Producing valuable aromatics from lignin through controlled depolymerization has attracted
much attention recently, especially with β-O-4 linkage as the key target, which accounts for …

In this paper, the roles of Na 2 CO 3 were investigated mainly for the lignite
hydroliquefaction process with Fe-based catalyst. As a whole, Na 2 CO 3 could play a …

In this study, the mesoporous ZrO 2 and Na-ZrO 2 were examined as heterogeneous solid
catalysts under supercritical water for the β-ether bond scission of phenethyl phenyl ether …

Since most oxygen containing structures in lignite will break at relatively low temperature
and macromolecular structure will pyrolyze at higher temperatures, two-stage liquefaction …

Efficient depolymerization of lignite under mild conditions is the key to realizing its low
carbon conversion and high value utilization. This study focuses on three Chinese lignites …

The reactivity and decomposition pathway of models for α-O-4 and β-O-4 linkages, found
within lignin, have been examined using methoxy-substituted (− OCH3) and-unsubstituted …

High oxygen content in lignite increases hydrogen consumption during hydroliquefaction,
and simultaneously the produced water decreases hydrogen partial pressure, which …
