A flash­ ing column downstream of the hydrodesulfurization reaction zone fractionates the effluent at a target cut point temperature to obtain two hydrocarbon fuel fractions. A first fraction boiling at or above the target cut point temperature contains the remaining refractory organosulfur compounds. A second fraction boiling below the target cut point temperature substantially is free of organosulfur com­ pounds, since the organosulfur compounds boiling in the range of this fraction were the labile organosulfur compounds which were initially removed by mild hydrodesulfurization. The first fraction contacted with gaseous oxidizing is a agent over an oxidation cata­ lyst having formula a Cu Zni_ Al 04 x x 2 in a gas phasecatalytic oxidation reaction zone to convert the refractory organosulfur com­ pounds to SO and x low sulfur hydrocarbons. The by-product SO x is subsequently removed, producing a stream containing reduced a level of organosulfur compounds.
