GL&V's washing, oxygen delignification
and bleaching operations with Compact Press, pumps and mixers technology for chemical pulping as well as the related Product Center in Karlstad Sweden are not included in the transaction scope.
Effect of lignin demethylation on oxygen delignification
. Appita J.
Enzyme application will include the recovery of phenolic compounds from enzymatic breakdown of technical lignin, And of lignin and hemicellulose compounds from enzymatic delignification
and bleaching of kraft pulp (also resulting in more sustainable final cellulosic pulp).
Therefore, to break down lignocellulosic bonds and to increase the bioavailability of nutrients, various physical and chemical delignification
methods have been examined in agricultural co-products, such as rice straw and wheat straw [2,3].
Optimal conditions sawdust delignification
of Pinus patula as crucial step in obtaining bioethanol
In the pulp and paper industry, PAA has been found to be an excellent alternative for delignification
and bleaching , though this market is still small.
The reason for this may be that the higher alkali concentration weakens the fiber by excess delignification
Considering the high efficiencies of delignification
as well as good oxidizing selectivity, direct application of the ozonation method on the pretreatment of the unbleached Kraft pulp instead of pure cellulose fibers for the NFC preparation would be feasible.
Bearing in mind that the lignin polymer represents a structural barrier to these effects, first it was necessary to perform the delignification
of LVS biomass.
