Lignin, the term commonly used in literature, represents a group of heterogeneous aromatic
compounds of plant origin. Protolignin or lignin in the cell wall is entirely different from the …

Lignin is a highly abundant biopolymer with a complex polyphenolic structure, making it a
potential source of aromatic precursors, polymers, and energy. However, its thermal stability …

Lignin can be precipitated from kraft black liquor (BL) through the addition of an acidifying
agent such as carbon dioxide or sulfuric acid. In most of the existing lignin precipitation …

We have developed an environmentally benign large-scale (50 kg wood meal per batch)
lignin production plant, operating based on acid-catalyzed polyethylene glycol (PEG) …

Prior Publication Data There is provided a process for recovery of lignin from a black US
2011 FO294991 A1 Dec. 1, 2011 liquor that contains either soluble or dispersed lignin …

In the last few years, a serious effort has been initiated to develop standard methods for
lignin characterization at the national and international levels. Thus, several Canadian and …

Lignin is a complex polymer that is a potential feedstock for aromatic compounds and
carboxylic acids by cleaving the β‐O‐4 and 5‐5′ linkages. In this work, a syringe pump …

A mild, simple process of preparing lignin nanoparticle dispersions is disclosed.
Additionally, compositions and methods of making lignin nanoparticle-polymer complexes …

The present invention relates to methods of processing lignocellulosic material to obtain
hemicellulose sugars, cellulose sugars, lignin, cellulose and other high-value products such …

The availability and multifunctionality of lignin makes it a desirable, renewable alternative to
petroleum for specialty and bulk chemicals. However, recovering lignin from black liquor is …
