Using cavitation for delignification of wood
Bioresource Technology, 2012The Kraft process is the most widely used chemical process for the removal of lignin and other polymers from wood to obtain cellulosic pulp fibres. In the present study, the effect of cavitation (growth and violent collapse of vapour bubbles in a liquid) on delignification of wood was investigated.

Gas dispersion in the oxygen delignification process
TAPPI Journal, 2021There has been very little knowledge about the state of gas dispersion in the oxygen delignification process, even though this has a major impact on the performance of the reactor. This paper presents a new continu-ous inline method for measuring oxygen bubble size distribution in the reactor, as well as results from studies con-ducted in softwood and ...

The Kinetics of Oxygen Delignification of Reed Kraft Pulp (I)-Kinetics of Delignification
Advanced Materials Research, 2011The kinetics of reed kraft pulp oxygen delignification process is studied, suitable kinetics model determined is -dk/dt=Aexp(-E/RT) [OH-]b[PO2]cKa, and the parameters in the model is calculated. The function for estimation of the kappa number at different reaction time is established for the reed kraft pulp oxygen delignification process.

Advances in microbial delignification
Biotechnology Advances, 1984Microbial delignification is a new field of applied research. The progress will therefore run parallel to the development of new basic knowledge on the physiological demands of white-rot fungi to degrade lignin and on new knowledge on enzyme mechanisms involved in lignin degradation.

Delignification of Miscanthus by Extraction
Separation Science and Technology, 2012Removal of lignin from miscanthus liberates cellulose and hemicellulose for hydrolysis to obtain sugars that can subsequently be fermented to ethanol or butanol. Extraction of lignin from raw miscanthus at 70°C is feasible when the extracting solvent contains a base (Ethylenediamine, EDA) mixed with an organic solvent or a mildly hydrophobic ionic ...

Delignification of softwood by ozonation
Pure and Applied Chemistry, 2009Ozonation of aspen sawdust of various moisture content (MC) values was investigated. Ozone consumption corresponding to the completion of the ozonation process was shown to be governed by the wood MC. Cellulose-containing material of a low (1–3 %) residual lignin content (LC) was produced under ozonation. It is proposed that ozone dissolved in water is
