Abstract The present invention describes a process for a controlled conversion of a biomass feedstock, wherein the process comprises the steps of: - loading the biomass feedstock to at least one reactor; - liquefaction of the biomass feedstock into a monomer and/or oligomer sugar mixture in said reactor by treatment in hot compressed liquid water (HCW) at subcritical- and/or supercritical condition, wherein the liquefaction is performed at a temperature of at least 280 °C during a time of from 1.5 to 30 seconds; and - removal of the monomer and/or oligomer sugar mixture, being the product molecules, to avoid continued detrimental decomposition. La présente invention concerne un procédé pour une conversion contrôlée d'une charge d'alimentation à base de biomasse, le procédé comprenant les étapes consistant à : - charger la charge d'alimentation à base de biomasse dans au moins un réacteur ; - liquéfier la charge d'alimentation à base de biomasse en un mélange de sucres monomères et/ou oligomères dans ledit réacteur par un traitement dans de l'eau liquide comprimée chaude (HCW) dans des conditions subcritiques et/ou supercritiques, la liquéfaction étant effectuée à une température d'au moins 280°C au cours d'un laps de temps de 1,5 à 30 secondes ; et - éliminer le mélange de sucres monomères et/ou oligomères, consistant en les molécules de produit, pour éviter une décomposition nuisible continuelle.
