Title (EN) METHOD FOR IMPREGNATING BIOMASS AND DEVICE FOR IMPREGNATING BIOMASS
(FR) PROCÉDÉ D'IMPRÉGNATION DE BIOMASSE ET DISPOSITIF D'IMPRÉGNATION DE BIOMASSE
Abstract:
(EN) The invention relates to a method for impregnating biomass (10). In a step (S100) of the method, a reactor unit (11) is fed with biomass (10) by means of a plug screw (12). In another step (S200), the reactor unit (11) is at least partially filled up to a predetermined fill level (13) with a reactant (18), such that a reaction between the fed biomass (10) and the reactant (18) takes place in order to obtain an impregnated biomass. In another step (S300), the impregnated biomass (10) is discharged from the reactor unit (11) for further processing (S300). The invention further relates to a device (1) for impregnating biomass (10).
(FR) L'invention concerne un procédé d'imprégnation de biomasse (10). Dans une étape (S100) du procédé, un ensemble réacteur (11) est alimenté en biomasse (10) au moyen d'une vis mâle (12). Dans une autre étape (S200), l'ensemble réacteur (11) est au moins partiellement rempli jusqu'à un niveau de remplissage prédéfini (13) avec un réactif (18), de sorte qu'une réaction entre la biomasse alimentée (10) et le réactif (18) ait lieu afin d'obtenir une biomasse imprégnée. Dans une autre étape (S300), la biomasse imprégnée (10) est évacuée de l'ensemble réacteur (11) pour un traitement ultérieur (S300). L'invention concerne en outre un dispositif (1) d'imprégnation de biomasse (10).
