Abstract
Procédé d'amélioration de la brillance de la pâte à papier mettant en oeuvre la combinaison d'une charge répartie de la liqueur blanche totale au cours des étapes de remplissage à température moyenne, de remplissage à chaud et de cuisson, dans le cadre d'un processus de cuisson par fournées, et de températures de cuisson faibles au cours de l'étape de cuisson. L'alcalinité active de la charge totale supérieure de liqueur blanche est de l'ordre de 15 à 35 %, tandis que les températures de cuisson sont comprises entre 150 et 168 ~C.
