The influence of pulp carryover on the efficiency of the xylanase (X) treatment of industrial
unbleached and oxygen-delignified eucalypt kraft pulps (A1 and A2 pulps, with kappa …

Loss of pulp yield and increased chemical oxygen demand (COD) of the effluent are the
main constraints to the wider application of xylanase-assisted bleaching of hardwood kraft …

The effects of treating industrial (laboratory-unwashed) oxygen-delignified eucalypt kraft
pulp with a commercial endo-xylanase (X) on ECF bleaching performance were evaluated …

Lignin is known to limit the enzyme-mediated hydrolysis of biomass by both restricting
substrate swelling and binding to the enzymes. Pretreated mechanical pulp (MP) made from …

Acidic xylanases possess the unique features necessary for the tolerance of acidic
environments, which may have great potentials for industrial purposes. However, factors …

Contemporary multi-stage bleaching processes partially remove residual lignin and
hexenuronic acid from cellulosic pulps. The reactions in the steps could be faster and …

Hemicelluloses are valuable sources of polysaccharides constituting 20-30% of wood. Since
the nature and quantities of hemicelluloses vary in different tree species, their valorization is …

Hardwood kraft pulp contains relatively high hexenuronic acid content which increases
unnecessary consumption of bleaching chemicals and has negative effects on pulp …

The study focuses on delignification of Kraft pulp using carbamide peroxide as bleaching
agent. The Kappa number reduction of bleached pulp is favored at low consistency of pulp …

Aims: The study aims at mitigating pulp kappa number before bleaching to minimize
pollution load. Study Design: An experimental study. Methodology: The various parameters …
