Abstract

L'invention concerne un système de coproduction d'énergie exempte de CO2 et d'hydrogène à partir de biomasse. Le système comprend un dispositif de génération d'énergie et un dispositif de génération d'hydrogène. Le dispositif de génération d'énergie comprend : un dispositif de gazéification à chauffage direct qui amène une biomasse qui a été fournie à partir d'un dispositif d'alimentation en biomasse à subir une réaction de décomposition/gazéification thermique et génère ainsi un gaz directement gazéifié ; et un dispositif de coalimentation de chaleur et d'énergie qui génère de la chaleur et de l'énergie à l'aide du gaz directement gazéifié. Le dispositif de génération d'hydrogène comprend : un dispositif de gazéification à chauffage indirect qui utilise la combustion d'un gaz de chauffage pour chauffer indirectement de la vapeur et des carbures dérivés de biomasse qui comprennent un résidu de gazéification contenant du charbon n'ayant pas réagi provenant de la réaction de décomposition/gazéification thermique et reforme à la vapeur les carbures issus de biomasse pour générer un gaz gazéifié riche en hydrogène ; un refroidisseur de gaz qui échange de la chaleur entre le gaz gazéifié riche en hydrogène et l'eau pour refroidir le gaz gazéifié riche en hydrogène et pour évaporer l'eau et fournir de la vapeur au dispositif de gazéification à chauffage indirect ; et un dispositif de séparation d'hydrogène qui sépare l'hydrogène du gaz gazéifié riche en hydrogène refroidi.
