Abstract[English]
The present invention describes a method for treating a feedstock originating from a renewable source comprising a hydrotreatment step a), a step b) of separation of at least one portion of the effluent resulting from step a) into at least one light fraction and at least one hydrocarbon effluent, a step c) of hydroconversion of the hydrocarbon effluent resulting from step c), using at least one specific bifunctional catalyst comprising at least one noble metal from group VIII selected from among platinum and palladium, and a support comprising at least one zeolite selected from among the MTW zeolites and the IZM-2 zeolite, alone or in a mixture, and at least one binder, a step d) of separation of the effluent resulting from step c), which makes it possible to separate at least one gaseous fraction and at least one hydrocarbon liquid effluent, and a step e) of fractionation of the hydrocarbon effluent resulting from step d) into at least one kerosene cut and at least one heavy cut having an initial boiling point of between 250 and 300°C, wherein all or part of the heavy cut resulting from the step e) is recycled to the hydroconversion step c).[French]
La présente invention décrit un procédé de traitement d'une charge issue d'une source renouvelable comprenant une étape a) d'hydrotraitement, une étape b) de séparation d'au moins une partie de l'effluent issu de l'étape a) en au moins une fraction légère et au moins un effluent hydrocarboné, une étape c) d'hydroconversion de l'effluent hydrocarboné issu de l'étape c) utilisant au moins un catalyseur bifonctionnel spécifique comprenant au moins un métal noble du groupe VIII choisi parmi le platine et le palladium et un support comprenant au moins une zéolithe choisie parmi les zéolithes de code structural MTW, et la zéolithe IZM-2 seules ou en mélange, et au moins un liant, une étape d) de séparation de l'effluent issu de l'étape c) qui permet de séparer au moins fraction gazeuse, et au moins un effluent liquide hydrocarboné, et une étape e) de fractionnement de l'effluent hydrocarboné issu de l'étape d) en au moins une coupe kérosène, au moins une coupe lourde ayant un point d'ébullition initial compris entre 250 et 300°C, avec recyclage de tout ou partie de ladite coupe lourde issue de ladite étape e) dans ladite étape c) d'hydroconversion.
