PROCESS FOR PREPARING A CATALYST CONTAINING MESOPORES, CATALYST THUS OBTAINED AND ITS USE IN A HYDROCONVERSION PROCESS

Номер: FR2981583B1

La présente invention concerne un procédé de préparation d'un catalyseur d'hydroconversion constitué essentiellement d'une zéolithe Y modifiée, comprenant les étapes de traitement d'une zéolithe Y modifiée par suspension de cette dernière dans une solution à pH basique, arrêt du traitement précédent par neutralisation de la solution contenant la zéolithe Y modifiée avec une solution contenant un acide, filtration de la suspension neutralisée et lavage du solide de zéolithe Y modifiée récupéré, séchage et calcination facultative du solide de zéolithe Y modifiée, mise en contact du solide de zéolithe Y modifiée, sous agitation, avec une solution d'échange d'ions, et vaporisation et/ou calcination facultative du composé de type zéolithe Y modifiée pour l'obtention du catalyseur essentiellement constitué d'une zéolithe Y modifiée. The present invention relates to a method for preparing a hydroconversion catalyst consisting essentially of a modified Y zeolite, comprising the steps of treating a modified Y zeolite by suspending it in a basic pH solution, stopping the treatment preceding by neutralizing the solution containing the modified Y zeolite with an acid-containing solution, filtering the neutralized suspension and washing the recovered modified Y-zeolite solid, drying and optionally calcining the modified Y-zeolite solid, contacting the zeolite Y modified, with stirring, with an ion exchange solution, and optional vaporization and / or calcination of the modified zeolite Y compound to obtain the catalyst consisting essentially of a modified Y zeolite.
