Abstract:
1. A process for hydrodesulphurizing a gasoline, comprising at least two successive hydrodesulfurizations, each hydrodesulfurization being conducted by subjecting a gasoline feed to a catalyst, wherein at least one hydrodesulfurization employs a catalyst comprising a support and an active phase comprising nickel or cobalt and in which the mean pore diameter of said catalyst is more than 20 nanometers, wherein activity of the catalyst of a hydrodesulfurization n+1 is 30-90% of the activity of hydrodesulfurization n, in which the successive steps are carried out without intermediate degassing, in which the reaction temperature in hydrodesulfurization n+1 is higher than that hydrodesulfurization n, and in which the catalyst of hydrodesulfurization n+1 has a lower metals content than that of the catalyst of hydrodesulfurization n.
