The present invention provides a method for emptying a reactor containing at least one bed of spent catalyst particles, wherein the reactor comprises at least one dump tube that opens into the reactor. The method comprises the steps of:

Method for completely emptying a catalytic reactor

The present invention provides a method for emptying a reactor containing at least one bed of spent catalyst particles, wherein the reactor comprises at least one dump tube that opens into the reactor. The method comprising the steps of:

The invention concerns a process for fluidising a catalyst or an adsorbent in a furnace which is fixed but the fluidised bed advances, optionally with rotation, in the presence of another inert solid with a granulometry which is different from that of the catalyst or the adsorbent, in the presence of a fluidisation gas, to carry out either stripping of a catalyst or an adsorbent or regeneration of a catalyst or an adsorbent in the furnace.

Process for treating a catalyst or an adsorbent in a fluidized bed

A process for presulfurizing a hydrocarbon treatment catalyst and/or for preconditioning a catalyst, comprising one or two stages of incorporating sulfur into the pores of a hydrocarbon conversion catalyst conducted off-site in at least one zone that contains a catalyst, preferably in motion, and with either suilirated hydrogen (H.sub.2 S), sulfur, or a sulfur compound capable of evolving nascent suilirated hydrogen.
