Abstract

L'invention concerne un procédé de réjuvénation d’un catalyseur d’hydrotraitement et/ou d’hydrocraquage au moins partiellement usé, ledit catalyseur comprenant un métal du groupe VIIl, un métal du groupe VIB et un support d’oxyde, ledit procédé comprenant les étapes suivantes : a) on régénère le catalyseur,b) puis on met en contact ledit catalyseur régénéré avec une solution d’imprégnation consistant en un mélange d’eau, d’au moins un précurseur d’un métal du groupe VIB, d’au moins un précurseur d’un métal du groupe VIII et d’au moins un composé organique, la quantité de composé organique introduite dans le catalyseur régénéré étant optimisée par rapport aux métaux déjà présents dans le catalyseur régénéré et par rapport à la quantité de métaux introduite via la solution d’imprégnation,c) puis on effectue une étape de séchage sans le calciner ultérieurement.
