Title
(EN) TORREFACTION PROCESS
(FR) PROCÉDÉ DE TORRÉFACTION
Abstract
(EN)
The present invention relates to a process for the torrefaction of a biomass feedstock for the production of a biofuel, the process comprising: (i) torrefaction of a biomass feedstock in a toroidal bed reactor, wherein the toroidal bed reactor comprises a reaction chamber with a substantially circumferentially directed flow of fluid generated therein to cause the biomass feedstock to circulate rapidly about an axis of the reaction chamber in a toroidal band, and to heat the biomass feedstock, wherein the fluid comprises gas or gases introduced into the reaction chamber and wherein the chamber is maintained under an oxygen-depleted atmosphere.
(FR)
La présente invention concerne un procédé de torréfaction d'une charge de biomasse pour la production d'un biocarburant, le procédé comprenant l'étape consistant à : (i) torréfier une charge de biomasse dans un réacteur à lit toroïdal, le réacteur à lit toroïdal comprenant une chambre de réaction dans laquelle est généré un flux de fluide dirigé de manière sensiblement circonférentielle pour faire circuler la charge de biomasse rapidement autour d'un axe de la chambre de réaction dans une bande toroïdale et pour chauffer la charge de biomasse, le fluide comprenant un gaz ou des gaz introduits dans la chambre de réaction et la chambre étant maintenue sous une atmosphère pauvre en oxygène.
