Abstract
The invention concerns an alumina based catalyst containing, expressed as the oxide content by weight, 2-10% by weight of cobalt oxide CoO, 10-30% by weight of molybdenum oxide MoO.sub.3 and 4-10% of phosphorous oxide P.sub.2 O.sub.5, with a BET surface area in the range 100-300 m.sup.2 /g, a crushing strength CSH of more than 1.4 MPa, and an average pore diameter in the range 8-11 nm, the pore volume of pores with diameter of more than 14 nm being less than 0.08 ml/g, or less than 22% of total pore volume, the volume of pores with a diameter of less than 8 nm being at most 0.05 ml/g, or less than 10% of total pore volume, the volume of pores with diameter less than 10 nm being in the range of 20%-70%, the volume of pores with diameter between 10 nm and 13 nm being in the range of 20%-60%, and the volume of pores with a diameter which is in the range 8 to 14 nm being in the range 0.20 ml/g to 0.8 ml/g. The invention also concerns a hydrotreatment process using the catalyst, in particular hydrodesulphuration.
