CA 2499696
The invention concerns a method for ex-situ oxidizing passivation of catalysts for hydrocarbon hydroconversion and in particular for hydrotreatment, in their sulphide state. Said method consists in contacting the sulphidized catalyst, during a heat treatment at above 50 ·C, with an oxidizing gas stream which may be dry or moist. Said invention for passivating sulphide phases can also be used for a process operating on a fixed or moving bed, for example a mobile bed process.
La présente invention concerne un procédé de passivation oxydante hors site des catalyseurs pour l~hydroconversion d~hydrocarbures et notamment d~hydrotraitement, dans leur état sulfurés, procédé dans lequel le catalyseur sulfuré est mis en contact, lors d~un traitement thermique à plus de 50~C, avec un flux gazeux oxydant qui peut être sec ou humide. Cette invention, pour la passivation de phases sulfurés, peut être, tout aussi bien mise en oeuvre pour un procédé fonctionnnant en lit fixe ou en lit en mouvement, par exemple en lit mobile.
