Green Process for Xylooligosaccharides Production using an Eucalyptus Kraft Pulp
Journal of Polymers and the Environment, 2022 Xylooligosaccharides (XOS) are oligomers with recognized and important prebiotic properties, whose consumption is associated with several health benefits, including a positive impact on the immune system. In this work, XOS were produced through a green process of enzymatic hydrolysis performed directly on an intermediate product from a pulp and paper ...

Tailor-made alkaliphilic and thermostable fungal laccases for industrial wood processing
Biotechnology for Biofuels and Bioproducts, 2022 Background During the kraft process to obtain cellulosic pulp from wood, most of the lignin is removed by high-temperature alkaline cooking, released in the black liquors and usually incinerated for energy. However, kraft lignins are a valuable source of

Kraft Lignin Conversion into Energy Carriers under the Action of Electromagnetic Radiation
Journal of Chemistry, 2019 In this work, it was found that the deposition of iron salts (iron acetate) on kraft lignin at extremely low concentrations of 0.1 wt.% leads to a sharp increase in the absorbing capacity of microwave radiation by kraft lignin at its power of 1 kW and ...

FAULT TOLERANT CONTROL APPLICATION FOR CONTINUOUS KRAFT PULPING PROCESS
IFAC Proceedings Volumes, 2006 Abstract In this study, the fault tolerant Kappa number control in continuous cooking application is investigated. The Kappa number is one of the quality measures in the pulp cooking process and usually the only on-line measurement. It is a measure of the residual lignin content in the pulp.
