Abstract

La présente invention concerne un procédé et un équipement de production de pâte à papier (95) à partir de matières végétales fibreuses. Ce procédé comprend la transformation de ces matières en pâte à papier, au moyen d'un solvant en ébullition comprenant une solution aqueuse d'un alcool aliphatique inférieur et un mélange additionnel comprenant au moins un additif choisi dans le groupe que constituent les sulfites, les bisulfites et un caustique.
