Using cavitation for delignification of wood

Bioresource Technology, 2012
The 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.

Delignification of Biomass Using Alkaline Glycerol

Energy Sources Part A Recovery, Utilization, and Environmental Effects, 2005
Ailanthus altissima and Spruce orientalis chips were delignified by using glycerol as a solvent and alkaline-gliycerol with and without catalyst at different temperatures (438, 458, 478, and 498 K) in atmospheric pressure, and results were compared with the other organic solvent systems.

Gas dispersion in the oxygen delignification process

TAPPI Journal, 2021
There 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, 2011
The 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.
