Claim 15:
16. The process as claimed in claim 1, in which, during a stage b′) carried out in parallel of stage b), another part of the effluent resulting from stage a) without removal of the H2S formed, hydrogen and a hydrodesulfurization catalyst comprising an oxide support and an active phase consisting of at least one metal from group VIII are brought into contact in at least one reactor at a temperature of between 280 and 400° C., at a pressure of between 0.5 and 5 MPa, with a space velocity of between 1 and 10 h−1 and a ratio of the hydrogen flow rate, expressed in standard m3 per hour, to the flow rate of feedstock to be treated, expressed in m3 per hour at standard conditions, of between 100 and 600 Sm3/m3, said temperature of stage b′) being higher than the temperature of stage a).
