A process for the hydrogenation of aromatics contained in a hydrocarbon feedstock and for the bulk sulfiding of a nickel-based catalyst to enhance the activity and catalyst life thereof. The process includes passing at the start-of-run a dispersed hydrocarbon feedstock through a bed of the nickel-based catalyst at an elevated temperature effective in promoting the bulk sulfiding the nickel-based catalyst so as to thereby increase its activity or catalytic life, or both.
L'invention concerne un procédé d'hydrogénation de composés aromatiques contenus dans une charge d'hydrocarbures et de sulfuration en volume d'un catalyseur à base de nickel pour en améliorer l'activité et la durée de vie. Le procédé consiste à faire passer au départ une charge d'hydrocarbures dispersée à travers un lit du catalyseur à base de nickel à une température élevée permettant de favoriser la sulfuration en volume du catalyseur à base de nickel en vue d'augmenter son activité et/ou sa durée de vie catalytique.
