A process for hydrodesulphurizing gasoline cuts is carried out in the presence of a catalyst comprising at least one group VIII element, at least one group VIB element, and a support with a specific surface area of less than about 200 m/g, wherein the density of the group VIB elements per unit surface area of the support is in the range 4&#xd7;10to 36&#xd7;10g of group VIB element oxides per mof the support.

Conducting the hydrodesulphurization of gasoline cuts in the presence of a catalyst comprising at least one support, at least one element of group VIII and tungsten, in which the atomic ratio (element of group VIII)/(element of group VIII+tungsten) is greater than 0.15 and less than 0.50, preferably 0.35&#x2013;0.40 inclusive.
