Abstract
The instant invention is directed to a process for removing hard sulfurs from hydrocarbon streams by selectively oxidizing hard sulfurs in a hydrotreated stream, under oxidizing conditions in the presence of an effective amount of an oxidizing agent, wherein the oxidizing agent is a peroxometal complex and wherein the hard sulfurs are oxidized into the corresponding sulfoxides and sulfones.
