Abstract[English]
The invention relates to a method for treating a feedstock comprising a plastics-derived and/or tyre-derived and/or solid-recovered-fuel-derived pyrolysis oil, which method comprises: b) hydrogenation of the feedstock and a portion of the liquid effluent resulting from the separation step e1) to obtain a hydrogenated effluent; c) hydrotreatment of the hydrogenated effluent to obtain a hydrotreated effluent; d) hydrocracking of the hydrotreated effluent to obtain a hydrocracked effluent; e1) separation of the hydrocracked effluent at high temperature and high pressure to obtain a gaseous effluent and a liquid effluent, a portion of which is recycled upstream of step b); e2) a separation/washing step carried out at low temperature and high pressure, fed with the gaseous effluent and optionally the other portion of the liquid effluent resulting from step e1) and an aqueous solution, to obtain a hydrocarbon effluent freed of its impurities.[French]
Procédé de traitement d'une charge comprenant une huile de pyrolyse de plastique et/ou de pneus et/ou de combustibles solides de récupération comprenant : b) une hydrogénation de ladite charge et une partie de l'effluent liquide issu de l'étape de séparation e1) pour obtenir un effluent hydrogéné, c) un hydrotraitement dudit effluent hydrogéné pour obtenir un effluent d'hydrotraité, d) un hydrocraquage dudit effluent hydrotraité pour obtenir un effluent hydrocraqué, e1) une séparation de l'effluent hydrocraqué opérée à haute température et haute pression pour obtenir un effluent gazeux et un effluent liquide dont une partie est recyclée en amont de l'étape b), e2) une étape de séparation/lavage opérée à basse température et haute pression alimentée par l'effluent gazeux et éventuellement l'autre partie de l'effluent liquide issu de l'étape e1) et une solution aqueuse, pour obtenir un effluent hydrocarboné débarrassé de ses impuretés.
