Microporous and Mesoporous Activated Carbons from Tea Stalk and Tea Stalk Pulps: Effect of Lignin Removal by One-Step and Two-Step Organosolv Treatment

open access: yesJournal of the Turkish Chemical Society, Section A: Chemistry
Delignification is a crucial pretreatment in the production of diverse value-added products from lignocellulosics. While modifying the surface functional groups, delignification also increases the specific surface area by providing a porous structure to ...

Effect of refining on delignification with a lacasse/xylanase treatment [PDF]

open access: yesBioResources, 2012
Previous research has demonstrated that a laccase/xylanase system (LXS) from white-rot fungus (Lentinus lepideus) has the same ability to delignify as a laccase/mediator system (LMS).

Lignin engineering in forest trees [PDF]

open access: yes, 2019
Wood is a renewable resource that is mainly composed of lignin and cell wall polysaccharides. The polysaccharide fraction is valuable as it can be converted into pulp and paper, or into fermentable sugars.

Mill experience of oxygen delignification.

open access: yesJAPAN TAPPI JOURNAL, 1988
The M-C oxygen delignification system for the eucalyptus line of our mill has started operation in January 1986.The Kappa number and viscosity reduction are around 49 % and 19% respectively.Also, the good results are shown in terms of brightness and dirt content.Whereas, the reduction of total effective chlorine consumption and COD in the bleaching ...

The conversion of lignocellulosics to fermentable sugars: A survey of current research and application to CELSS [PDF]

open access: yes
An overview of the options for converting lignocellulosics into fermentable sugars as applied to the Closed Ecological Life Support System (CELSS) is given. A requirement for pretreatment is shown as well as the many available options.

Evaluation of kraft cooking behaviour for different hardwood species [PDF]

open access: yes, 2010
In this study six wood species (birch, chestnut, oak, beech, poplar and eucalyptus) were analysed separately. Lignin content, Polysaccharides content (cellulose and hemicelluloses), Yield, Hexenuronic acids were evaluated for three cooking temperatures

Influence of xylan content on the oxygen delignification performance of eucalypt kraft pulps as studied using prehydrolysis and xylanase treatments [PDF]

open access: yesBioResources, 2012
Common metrics for evaluating the efficiency of oxygen delignification include the kappa number and Klason lignin content. As a change in xylan content often leads to a change in HexA content, the kappa number must be corrected for the HexA contribution ...
