Definitions

  • the pretreatment process generally requires more than one operational step, including additive impregnation and intermediate or final wash of the pretreated biomass, which may result in lower temporal productivity (mass produced / time of process) and higher water consumption per unit of pre-treated biomass produced, even in cases where there is a significant reuse and recirculation rate of the liquid streams produced in the pretreatment stage.

Abstract

L'invention concerne un procédé de pré-traitement de biomasse lignocellulosique pour la production d'hydrates de carbone et d'autres sous-produits, réalisé en deux étapes, dont l'une au moins fait intervenir un additif azoté, notamment un carbamide, dans un procédé hydrothermique permettant une récupération maximale de sucres à partir des hémicelluloses et de la cellulose, avec une dégradation minimale des sucres disponibles, de manière à produire des hydrates de carbone qui peuvent être convertis en biocombustibles et en produits chimiques, tels que l'éthanol, le butanol et une pluralité de produits d'intérêt industriel, par l'intermédiaire de voies chimiques et biochimiques.
