Abstract
Method for treating a partially desulphurised sulphur-containing hydrocarbon feedstock from a preliminary hydrodesulphurisation step in the presence of a catalyst comprising an active phase comprising a group VII metal and a mesoporous and macroporous alumina support comprising a bimodal distribution of mesopores, wherein: —the volume of mesopores having a diameter greater than or equal to 2 nm and less than 18 nm is between 10 and 30% by volume of the total pore volume of the support; —the volume of mesopores having a diameter greater than or equal to 18 nm and less than 50 nm is between 30 and 50% by volume of the total pore volume of the support; —the volume of macropores having a diameter greater than or equal to 50 nm and less than 8000 nm is between 30 and 50% by volume of the total pore volume of the support.
