Abstract

L'invention concerne un procédé pour éliminer des poisons métalliques comme du nickel, du fer et/ou du vanadium d'un catalyseur de conversion d'hydrocarbures. Ce procédé comprend les étapes consistant à mettre en contact le catalyseur avec un milieu de lavage réducteur et ensuite avec un milieu de lavage oxydant de manière à éliminer au moins une portion des poisons métalliques du catalyseur. Un milieu de lavage oxydant préféré comprend une solution aqueuse d'eau oxygénée. Les métaux vanadium et nickel peuvent être récupérés à partir des solutions de lavage usées résultantes pour une utilisation métallurgique éventuelle.
