Described are methods for pretreating lignocellulosic biomass that comprise passing a hot aqueous biomass slurry through a heat exchange passage from an inlet to an outlet and locally regulating pressure in the passage by feed of a pressurized liquid medium to one or more intermediate locations of the passage. Also described are methods for producing ethanol from the pretreated biomass.
L'invention porte sur des procédés de prétraitement d'une biomasse lignocellulosique qui comprennent le passage d'une bouillie de biomasse aqueuse chaude à travers un passage d'échange de chaleur d'une entrée à une sortie, et la régulation locale de la pression dans le passage par alimentation d'un milieu liquide pressurisé vers un ou plusieurs emplacements intermédiaires du passage. L'invention porte également sur des procédés pour produire de l'éthanol à partir de la biomasse prétraitée.
