Abstract[English]
The invention relates to a method for the hydrothermal liquefaction of an initial carbonaceous feedstock (1) in order to obtain a biocrude, the method comprising the following steps: - step a) of mixing the feedstock (1) with a catalyst and a liquid; - step b) of hydrothermal liquefaction (5) of the mixture (3); - step c) of liquid-liquid-gas separation (8) of the liquefaction product (7) in order to obtain a first gas phase (31), a second aqueous liquid phase (10) and a second organic liquid phase (18), referred to as biocrude; - step d) of separating the second aqueous phase (10) in order to obtain a third aqueous liquid phase (12) and a first water vapour phase (22); - step e) of diluting the second organic liquid phase (18); - step f) of bringing the diluted biocrude (20) into contact with at least one solvent (17, 23, 24) using counter-current liquid-liquid extraction so as to obtain a raffinate (25) and an extract (16); - step g) of separating the raffinate (25) so as to obtain the biocrude depleted in mineral compounds (27) and a phase (9, 28) comprising the diluent; - step h) of condensing the first vapour phase (22) and of recycling it as a solvent (17) to step f); - step i) of recycling the extract (16) to step d); - step j) of separating a second part of the first vapour phase (22).[French]
L'invention se rapporte à un procédé de liquéfaction hydrothermale d'une charge carbonée initiale (1) afin d'obtenir un biocrude: - étape a) de mélange de la charge (1) avec un catalyseur et un liquide, - étape b) de liquéfaction hydrothermale (5) du mélange (3), - étape c) de séparation liquide/liquide/gaz (8) du produit de liquéfaction (7) afin d'obtenir une première phase gazeuse (31), une deuxième phase aqueuse liquide (10) et une deuxième phase organique liquide (18) dite biocrude, - étape d) de séparation de la deuxième phase aqueuse (10) afin d'obtenir une troisième phase aqueuse liquide (12), et une première phase de vapeur d'eau (22), - étape e) de dilution de la deuxième phase organique liquide (18) - une étape f) de contactage du biocrude dilué (20) avec au moins un solvant (17,23,24), avec extraction liquide-liquide à contre-courant, de façon à obtenir, d'une part, un raffinat (25), et d'autre part un extrait (16), - une étape g) de séparation du raffinat (25), de façon à obtenir le biocrude appauvri en composés minéraux (27) et une phase (9,28) comprenant le diluant, - une étape h) de condensation de la première phase vapeur (22) et de recyclage comme solvant (17) à l'étape f), - une étape i) de recyclage de l'extrait (16) vers l'étape d), - une étape j) de séparation d'une deuxième partie de la première phase vapeur (22).
