The invention relates to a process of producing a xylose solution from a biomass hydrolysate by subjecting the biomass hydrolysate to nanofiltration and recovering as the nanofiltration permeate a solution enriched in xylose. The biomass hydrolysate used as starting material is typically a spent liquor obtained from a pulping process.
Cette invention se rapporte à un procédé servant à produire une solution de xylose à partir d'un hydrolysat de biomasse, ce procédé consistant à soumettre l'hydrolysat de biomasse à une opération de nanofiltration et à récupérer comme perméat de l'opération de nanofiltration une solution enrichie en xylose. L'hydrolysat de biomasse utilisé comme matériau de départ est généralement une liqueur épuisée obtenue par un procédé de réduction en pâte.
