Title
(EN) CATALYTIC AND CONTINUOUS THERMOCHEMICAL PROCESS OF PRODUCTION OF VALUABLE DERIVATIVES FROM ORGANIC MATERIALS AND/OR WASTE
(FR) PROCÉDÉ THERMOCHIMIQUE ET CONTINU DE PRODUCTION DE DÉRIVÉS DE VALEUR À PARTIR DE MATIÈRES ET/OU DE DÉCHETS ORGANIQUES
Abstract
(EN) The present invention relates to a novel liquid-liquid extraction process of a bio-oil obtained by an improved thermochemical process. This extraction process gives rise to two distinct phases: an organic phase, with bio-oil of energetic added value, and an aqueous phase, where the following can be obtained by chemical compounds with added value: lactic acid, formic acid, hydroxymethylfurfural, furfural, levulinic acid, monosaccharides, disaccharides and compounds with antioxidant properties, among others.

Ce procédé d'extraction permet d'obtenir deux phases distinctes : une phase organique, avec une bio-huile à valeur ajoutée énergétique, et une phase aqueuse, où les éléments suivants peuvent être obtenus par des composés chimiques à valeur ajoutée : l'acide lactique, l'acide formique, l'hydroxyméthylfurfural, le furfural, l'acide lévulinique, les monosaccharides, les disaccharides et les composés ayant des propriétés antioxydantes, entre autres.
