摘要： This invention relates to a process of ex-situ oxidizing passivation of catalysts for hydroconversion of hydrocarbons and especially of hydrotreating, in their sulfide state, process in which the sulfurized catalyst is brought into contact with an oxidizing gas flow that can be dry or wet, during heat treatment at more than 50° C. This invention, for passivation of sulfide phases, can be equally well implemented for a process that takes place in a fixed bed or a fluidized bed, for example a moving bed.

摘要： The present invention includes a method for emptying a reactor containing at least one bed of spent catalyst particles and that comprises at least one dump tube, which opens into the reactor in the bottom portion of the bed of particles or underneath the latter. The method comprises the following:

a first step of causing a proportion of the catalyst bed to flow out of the reactor via said dump tube; then
a second step of expelling out of the reactor the catalyst remainder, by driving towards the opening of the dump tube the catalyst particles remaining in the reactor at the end of the first step, this step being performed by means of a removable device introduced into the reactor via the dump tube,

and is characterised in that said removable device comprises an articulated arm bearing one or more protuberances spirally disposed about a rotary axis.
