Abstract[English]
The present invention describes a method for treating a feedstock originating from a renewable source for the production of a kerosene cut or of a gas oil base, using a sequence of two specific bifunctional catalysts, comprising at least one metal from group VIII and/or from group VIB, taken alone or as a mixture and an acid support, and preferably silica-alumina, for the first catalyst and at least one metal from group VIII and/or from group VIB and a support comprising one or more specific zeolites chosen from zeolites of FER, EUO, *MRE, MTW and MOR framework type and zeolite IZM-2, alone or as a mixture, and preferably chosen from the zeolites of MTW framework code and IZM-2 for the second catalyst, in two successive hydroconversion steps without a final fractionation step making it possible to obtain a kerosene cut to the specifications of the ASTM D7566 standard with a maximized yield of said cut, said method also making it possible to alternatively obtain a gas oil base that can be incorporated into the gas oil pool, without loss of yield compared to a method that does not use the specific catalyst sequence according to the invention.[French]
La présente invention décrit un procédé de traitement d'une charge issue d'une source renouvelable pour la production d'une coupe kérosène ou d'une base gazole, mettant en œuvre un enchainement de deux catalyseurs spécifiques bifonctionnels, comprenant au moins un métal du groupe VIII et/ou du groupe VIB, pris seuls ou en mélange et un support acide et de préférence la silice alumine, pour le premier catalyseur et au moins un métal du groupe VIII et/ou du groupe VIB et un support comprenant une ou plusieurs zéolithes spécifiques choisies parmi les zéolithes de type structural FER, EUO, *MRE, MTW, MOR et la zéolithe IZM-2 seules ou en mélange et de préférence choisies parmi les zéolithes de code structural MTW et l'IZM-2 pour le second catalyseur, dans deux étapes d'hydroconversion successives sans étape de fractionnement finale permettant d'obtenir une coupe kérosène aux spécifications de la norme ASTM D7566 avec un rendement maximisé en ladite coupe, ledit procédé permettant également d'obtenir alternativement une base gazole incorporable au pool gazole, sans perte de rendement par rapport à un procédé ne mettant pas en œuvre l'enchaînement spécifique de catalytique selon l'invention.
