1. Desulfurization process for a cut containing hydrocarbons comprising sulfur and olefinic compounds and having at least the following successive steps:

  • a first desulfurization in the presence of hydrogen and a hydrodesulfurization catalyst under conditions leading to a desulfurization rate of said cut strictly higher than 90%, separation of most of the hydrogen sulfide (H2S) from the effluents resulting from the first desulfurization, a second desulfurization of the effluents, with the hydrogen sulfide removed, resulting from the separation step, in the presence of hydrogen and of a hydrodesulfurization catalyst and under conditions leading to a desulfurization rate of said effluents less than that of the first desulfurization.
