Effect of pulping and bleaching on pulp carbohydrates and technical properties [PDF]

open access: yes, 1996
Pulping and bleaching have a profound effect on the carbohydrate chem. of kraft pulps.  The chem. structure of xylan is modified due to the conversion of methylglucuronic acid side groups to hexenuronic acid side groups.

Sustainable Manufacturing of Pulp from Deadwood: Process Aspects and Pulp Properties

open access: yesProcesses
This paper studies a two-stage oxygen-alkaline treatment and subsequent bleaching of softwood sulfate pulp obtained from healthy and deadwood of spruce and larch. Delignification was carried out at elevated temperature and pressure in an alkaline medium with the addition of hydrogen peroxide, after which the pulp was subjected to classic ECF cycles ...
