The instant invention is directed to a process for removing hard sulfurs from hydrocarbon streams comprising: selectively oxidizing hard sulfurs in a hydrotreated stream, under oxidizing conditions in the presence of an effective amount of an oxidizing agent, wherein said oxidizing agent is a peroxometal complex and wherein said hard sulfurs are oxidized into the corresponding sulfoxides and sulfones.
Cette invention a trait à un procédé permettant d'extraire des soufres durs de courants d'hydrocarbures, lequel procédé consiste à oxyder de manière sélective des soufres durs dans un courant ayant fait l'objet d'un hydrotraitement et ce, dans des conditions oxydantes en présence d'une quantité efficace d'un agent oxydant, en l'occurrence, un complexe peroxométallique. Les soufres durs oxydés se transforment en sulfoxydes et sulfones correspondants.
