17 Claims

1. A process for treating a partially desulfurized, sulfur-containing hydrocarbon feedstock resulting from a preliminary step of catalytic hydrodesulfurization, said process comprising:

subjecting said feedstock to partially desulfurization at a temperature of between 200° C. and 400° C., a pressure of between 0.2 and 5 MPa, at an hourly space velocity, defined as the volume flow rate of feedstock at the inlet per volume of catalyst used, of between 0.1 h⁻¹and 20 h⁻¹, in the presence of a catalyst comprising an active phase comprising at least one group VIII metal, said active phase not comprising any group VIB metal, and a mesoporous and macroporous alumina support comprising a bimodal distribution of mesopores and wherein:

the volume of mesopores with 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 said support;

the volume of mesopores with 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 said support;

the volume of macropores with 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 said support.
