Abstract[English]
The invention relates to a method for treating a liquid feedstock that comprises at least partially carbonaceous products resulting from a hydrothermal liquefaction treatment, referred to as a biocrude feedstock (1), with a view to reducing the content of mineral compounds thereof, such that the treatment comprises: - a step a) of diluting the biocrude feedstock with a diluent (8) which comprises an organic liquid phase so as to obtain a diluted biocrude feedstock (9); - a step b) of bringing the diluted biocrude feedstock obtained in step a) into contact with at least one solvent (3) which comprises an aqueous liquid phase, with counter-current liquid-liquid extraction, so as to obtain a raffinate (5) comprising the biocrude feedstock depleted in mineral compounds and the diluent, and an extract (4) comprising the solvent enriched in mineral compounds; and - a step c) of separating the raffinate (5) obtained in step b), so as to obtain the biocrude feedstock depleted in mineral compounds (7), and a phase comprising the diluent (8).[French]
L'invention se rapporte à un procédé de traitement d'une charge liquide qui comprend des produits au moins en partie carbonés issue d'un traitement de liquéfaction hydrothermale, dite charge biocrude (1), en vue d'en réduire la teneur en composés minéraux, tel que ledit traitement comprend - une étape a) de dilution de la charge de biocrude avec un diluant (8) qui comprend une phase liquide organique, de façon à obtenir une charge de biocrude diluée (9), - une étape b) de contactage de la charge de biocrude diluée obtenue à l'étape a) avec au moins un solvant (3) qui comprend une phase aqueuse liquide, avec extraction liquide-liquide à contre-courant, de façon à obtenir, d'une part, un raffinat (5) comprenant la charge de biocrude appauvrie en composés minéraux et du diluant, et d'autre part un extrait (4) comprenant le solvant enrichi en composés minéraux, - une étape c) de séparation du raffinat (5) obtenu à l'étape b), de façon à obtenir, d'une part, la charge biocrude appauvrie en composés minéraux (7) et d'autre part une phase comprenant le diluant (8).
