| Zusammenfassung: | The present invention concerns a process for ex situ oxidizing passivation of hydrocarbon hydroconversion catalysts, in particular for hydrotreatment in their sulphurized states, in which the sulphurized catalyst undergoes two treatments: contact with an oxidizing gas stream, and contact with an organic liquid (for example hydrocarbon) which partially fills its pores. |
