Characterization of Eucalyptus nitens Lignins Obtained by Biorefinery Methods Based on Ionic Liquids

Molecules, 2020
Eucalyptus nitens wood samples were subjected to consecutive stages of hydrothermal processing for hemicellulose solubilization and delignification with an ionic liquid, i.e., either 1-butyl-3-methylimidazolium hydrogen sulfate or triethylammonium ...

Oxygen Delignification of Acid Sulfite and Bisulfite Softwood Pulps

BioResources, 2015
This study discusses alternatives for the production of sulfite pulps cooked to high kappa numbers, and a subsequent oxygen treatment by using the same cation in the cooking and in the oxygen stages. Magnesium was used as a cation during both the cooking

Delignification Kinetics of Corn Stover with Aqueous Ammonia Soaking Pretreatment

BioResources, 2016
Soaking aqueous ammonia (SAA) pretreatment of corn stover was carried out at three temperatures (30, 50, and 70 ºC) and three concentrations of ammonia solution (5, 15, and 25 wt.%). The delignification kinetic model, based on three first-order reactions,

Process parameters affecting the delignification of eucalyptus kraft pulp with peroxyacetic acid [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2004
Various process parameters affecting eucalyptus kraft pulp delignification with peroxyacetic acid were investigated. The results showed that pH was an important factor. The delignification rate increased with increasing pH to the value of 6.
