Abstract
Ce procédé consiste à soumettre une pâte lignocellulosique par une cuisson à la séquence des traitements suivants: a) un traitement délignifiant par l'oxygène, suivi b) d'un traitement par un agent complexant ou séquestrant des métaux de transition suivi d'un lavage, puis c) d'un traitement par le péroxyde d'hydrogène, en présence de silicate d'un métal alcalin à une température supérieure à 100 °C et sous une pression de 5 à 200 bars.
