Abstract
L'invention concerne un procédé pour produire une pâte mécanique et semi-chimique avec un rendement supérieur à 85 %, à partir d'un matériau contenant de la lignocellulose, pour la fabrication de produits du type papier et carton. Le produit est soumis à un traitement mécanique au moins en deux étapes. Le produit à l'alimentation dans la première étape a une température au-dessous de la température de ramollissement de la lignine. Lorsqu'on transfère le matériau vers au moins une étape subséquente de traitement, il a une température supérieure à la température de ramollissement de la lignine.
