ABSTRACT:
For the impregnation into the pores of a hydrocarbon treatment catalyst of a sulfurizing agent chosen from element sulfur and organic polysulfides with the aid of a solvent, the impregnation process totally or partially comprises a constituent of the olefin or olefin fraction type, e.g., of the vegetable oil type, or a similar constituent. The use of such a constituent makes it possible to significantly reduce the exothermal effect which occurs during presulfurization, compared with the exothermal effects obtained without using such a constituent.
