Abstract
For hydrodesulfurization of an olefinic gasoline cut containing sulfur, the gasoline cut, hydrogen, and a catalyst are brought into contact. The catalyst comprises a group VIB metal, a group VIII metal, and a mesoporous and macroporous alumina substrate having a bimodal mesopore distribution. The volume of mesopores having a diameter greater than or equal to 2 nm and less than 18 nm corresponds to between 10 and 30% by volume of the total pore volume of the substrate. The volume of mesopores having a diameter greater than or equal to 18 nm and less than 50 nm corresponds to between 30 and 50% by volume of the total pore volume of the substrate. The volume of macropores having a diameter greater than or equal to 50 nm and less than 8000 nm corresponds to between 30 and 50% by volume of the total pore volume of the substrate.
