Abstract

L'invention concerne un procédé d'élimination d'un produit d'extraction du bois au cours de la production de pâte mécanique, le procédé consistant à imprégner une matière ligno-cellulosique hachée, destinée à être utilisée dans la production de pâte avant défibrage mécanique, à l'aide d'un liquide contenant un peracide présentant une valeur de pH maximum de 7, la quantité de peracide étant comprise entre 0,5 et 20 kg/tonne de matière ligno-cellulosique sèche, cette quantité représentant du peracide à 100 %. L'invention concerne également un procédé de production de pâte mécanique.
