1. A method of upgrading a hydrocarbon feedstock by removal of sulfones and sulfoxides therefrom, which comprises the steps ofa. supplying a hydrocarbon feedstock to an oxidation reactor, the hydrocarbon feedstock comprising sulfur-containing compounds;

  • b. contacting the hydrocarbon feedstock with an oxidant in the presence of a catalyst in the oxidation reactor under conditions sufficient to selectively oxidize sulfur compounds present in the hydrocarbon feedstock to produce a hydrocarbon stream that comprises hydrocarbons and oxidized sulfur-containing compounds;

    c. separating the oxidized sulfur-containing hydrocarbon stream into an aqueous phase and a non-aqueous oxidized effluent;

    d. recovering the non-aqueous oxidized effluent and contacting it with an electron donor agent to oxidize sulfones and sulfoxides present in the non-aqueous oxidized effluent; and

    ,e. separating and recovering the hydrocarbon stream from which the sulfones and sulfoxides have been removed.
