Abstract[English]
The invention relates to a method for treating a feedstock resulting from a hydrothermal liquefaction treatment with a view to reducing the content of mineral compounds, the method comprising the following steps: - step a) of diluting the biocrude feedstock with a diluent (8, 12) which comprises an organic liquid phase so as to obtain a diluted biocrude feedstock (9); - step b) of bringing the diluted feedstock (9) obtained in step a) into contact with two separate solvents, which are brought into contact with the feedstock in separate contacting zones (3; 7) and comprise a first solvent (3) which is an aqueous liquid phase having a neutral pH and a second solvent (10) which is an acidic aqueous liquid phase, using counter-current liquid-liquid extraction so as to obtain a raffinate (5) comprising the feedstock depleted in mineral compounds and the diluent and an extract (4) comprising the solvents enriched in mineral compounds; - step c) of separating the raffinate (5) obtained in step b) so as to obtain a biocrude feedstock depleted in mineral compounds (11) and a phase comprising the diluent (8, 12).[French]
L'invention se rapporte à un procédé de traitement d'une charge issue d'un traitement de liquéfaction hydrothermale en vue d'en réduire la teneur en composés minéraux, avec - une étape a) de dilution de la charge de biocrude avec un diluant (8,12) qui comprend une phase liquide organique de façon à obtenir une charge de biocrude diluée (9), - une étape b) de contactage de la charge diluée (9) obtenue à l'étape a) avec deux solvants distincts qu'on met en contact avec ladite charge dans des zones de contactage distinctes (3;7) et comprenant un premier solvant (3) qui est une phase liquide aqueuse à pH neutre et un deuxième solvant (10) qui est une phase liquide aqueuse acide, avec extraction liquide-liquide à contre-courant, de façon à obtenir un raffinat (5) comprenant la charge appauvrie en composés minéraux et du diluant, et un extrait (4) comprenant les solvants enrichis en composés minéraux, - une étape c) de séparation du raffinat (5) obtenu à l'étape b), de façon à obtenir une charge biocrude appauvrie en composés minéraux (11) et une phase comprenant le diluant (8,12).
