Abstract

L'invention concerne un procédé de fabrication de pâtes papetières chimiques par délignification de matériau ligno-cellulosique. Ce procédé se caractérise en ce que la solution alcaline utilisée pour la seconde cuisson contient de 0,1 à 1 % en poids de peroxyde par rapport au poids de la matière sèche défibrée. Application envisagée : fabrication de pâtes de papier.
