Abstract

L'invention concerne un procédé de blanchiment de pâtes à papier à haut rendement au moyen de peroxyde d'hydrogène en milieu alcalin, caractérisé en ce que la seule intervention faite entre le début et la fin dudit blanchiment est la modification de l'alcalinité de la pâte par addition d'un agent alcalin à un moment où la quantité
de peroxyde d'hydrogène consommée est comprise entre 40% et 75% de la quantité initiale de peroxyde d'hydrogène.
