Abstract:
A process for activation of a hydroconversion catalyst containing at least one metal of group VIII and at least one acid element, said process comprising impregnating at least two light petroleum fractions distilled at a temperature less than 400.degree. C., into said catalyst, at least one fraction being devoid of a nitrogen-containing compound and containing a sulfur-containing compound, and at least one fraction containing a nitrogen containing compound and a sulfur-containing compound, with the provision that a sulfur amount (QS) is impregnated before the catalyst temperature reaches 250.degree. C. and is at least equal to half a sulfur amount QS.sub.0 necessary for the complete sulfurization of the catalyst, and the fraction containing the nitrogen-containing compound is impregnated before the catalyst temperature reaches 270.degree. C.
