Title
(EN) A BIOMASS TREATMENT PROCESS AND SYSTEM
(FR) PROCÉDÉ ET SYSTÈME DE TRAITEMENT DE BIOMASSE
Abstract
(EN)
The present invention provides processes and systems for treating biomass and, e.g., making biofuels, such as bioethanol, from the biomass. More particularly, one process according to the present invention includes (a) inducing at least a first portion of a composition containing biomass and a working fluid to flow into a passage of a fluid processing apparatus, (b) injecting a high velocity transport fluid into the composition through a nozzle communicating with the passage of the fluid processing apparatus, whereby the transport fluid applies a shear force to the composition such that the working fluid is atomised and a vapour and droplet flow regime is formed downstream of the nozzle, (c) condensing the vapour and droplet flow regime, (d) transferring the composition to a first holding vessel, and (e) holding the composition in the first holding vessel at a first predetermined temperature for a first predetermined period of time, wherein a liquefaction enzyme is added to the composition prior to or during the process. Thereafter, the composition may be further processed to form a biofuel, such as, e.g., bioethanol.
(FR)
La présente invention concerne des procédés et systèmes de traitement de biomasse, et, par exemple, la fabrication de biocombustibles, tels que du bioéthanol, à partir de biomasse. L'invention concerne plus particulièrement un procédé consistant: (a) à faire passer dans un passage d'un appareil de traitement fluidique au moins une première partie d'une composition contenant de la biomasse et un fluide de travail, (b) à injecter dans la composition par une buse communiquant avec le passage de l'appareil de traitement fluidique, un fluide de transport qui applique à la composition une force de cisaillement servant à atomiser le fluide de travail et à former un courant de vapeur et de gouttelettes en aval de la buse, (c) à soumettre à condensation le régime d'écoulement de vapeur et des gouttelettes, (d) à transférer la composition vers une première cuve d'attente, et (e) à maintenir la composition dans la première cuve d'attente à une première température prédéterminée pendant une première période de temps prédéterminée, une enzyme de liquéfaction étant ajoutée à la composition avant ou pendant le traitement. Cette composition peut alors subir un traitement ultérieur visant à la réalisation d'un biocombustible tel que, par exemple, du bioéthanol.
