ABSTRACT:
A process to substantially reduce the sulfur content of a liquid hydrocarbon stream by contacting the hydrocarbon stream with an aqueous stream containing a mixture of one or more extraction agents selected from hypochlorites, cyanurates and alkali metal and alkaline earth metal hydroxides, optionally in the presence of a catalyst, to remove sulfur compounds.
