English abstract: Desulfurization of hydrocarbon feeds is achieved by firstly contacting the entire feed with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to remove the labile organosulfur compounds. A flashing 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 is substantially free of organosulfur compounds, since the organosulfur compounds boiling in the range of the fraction are the labile organosulfur compounds which are initially removed by mild hydrodesulfurization. The first fraction is contacted with a gaseous oxidizing agent over an oxidation catalyst having a formula CuxZn1-xA12O4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOx and low sulfur hydrocarbons. The by-product SOx is subsequently removed, thereby producing a stream containing a reduced level of organosulfur compounds.
