Process for hydrodesulphurizing cuts containing sulphur containing compounds and olefins in the presence of a supported catalyst comprising group VIII and VIB elements

摘要

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 m²/g, wherein the density of the group VIB elements per unit surface area of the support is in the range 4x10^-4 to 36x10^-4 g of group VIB element oxides per m² of the support.
