Process of pretreatment of a refining or petrochemistry catalyst, consisting, depending on the nature of the catalyst, either in incorporating sulphur into the catalytic mass or in chemically reducing the active metals of the catalytic mass. The invention is characterised in that at least part of this pretreatment is carried out in a rotating shell in which heating tubes are distributed in concentric circles. <IMAGE>
