<p>Process for sulfuration of hydrorefining catalysts characterized in that the sulfurizing agent is at least one organic polysulfur having the general formula R - Sn - R', wherein R and R', identical or different, represent a linear or branched alkyl radical saturated or unsaturated in C1 to C4 and n is comprised between 3 and 10. This process makes it possible to obtain an efficient sulfuration at temperatures which are not very high.</p> |
