Process for the hydrodesulphurization of a gasoline cut in the presence of a supported sulphide catalyst prepared using at least one cyclic oligosaccharide

A process for the hydrodesulphurization of a gasoline cut containing hydrocarbons containing at least 2 carbon atoms per molecule and having an end point of 250° C. or less, said process consisting of bringing said gasoline cut into contact with at least one catalyst the active phase of which comprises at least one metal from group VIII and at least one metal from group VIB deposited on a support formed from at least one oxide, said catalyst being prepared using a process comprising at least:

• i) at least one step for bringing at least said support into contact with at least one solution containing at least one precursor of at least said metal from group VIII and at least one precursor of at least said metal from group VIB;
• ii) at least one step for bringing at least said support into contact with at least one organic compound formed from at least one cyclic oligosaccharide composed of at least 6α-(1,4)-bonded glucopyranose subunits;
• iii) at least one drying step to obtain at least said metal from group VIII and at least said metal from group VIB in the oxide form;
• then
• iv) at least one sulphurization step such that said active phase is in the sulphide form;
• the steps i) and ii) possibly being carried out separately, in any order, or simultaneously.
