Finishing hydrodesulfurization catalyst comprising a group vib metal, a group viii metal and phosphorus on an alpha alumina support

Abstract

A polishing hydrodesulfurization catalyst comprising an active phase comprising at least one group VIB metal and at least one group VIII metal, phosphorus, and a porous support comprising alpha-alumina, the content of group VIB metal, measured in oxide form, being between 1% and 8% by weight relative to the total weight of the catalyst, the content of group VIII metal, measured in oxide form, being between 0.2% and 5% by weight relative to the total weight of the catalyst, and the content of phosphorus, measured in its P2O5 form, being between 0.1% and 3% by weight relative to the total weight of the catalyst, said catalyst having a specific surface area of greater than or equal to 1 m2/g and less than 20 m2/g. The catalyst of one example contains the oxides of Co, Mo and P on alpha-alumina.
