Trimetallic catalyst made from nickel, molybdenum and tungsten and use thereof in a hydrotreatment and/or hydrocracking process

A catalyst comprising:

• a support based on alumina or silica or silica-alumina, and an active phase consisting of nickel, molybdenum and tungsten, and phosphorus, wherein:
• the content of nickel, measured in the NiO form, is between 3% and 4% by weight, with respect to the total weight of the catalyst,
• the content of molybdenum, measured in the MoO3 form, is between 2% and 4% by weight, with respect to the total weight of the catalyst,
• the content of tungsten, measured in the WO3 form, is between 34% and 40% by weight, with respect to the total weight of the catalyst,
• the content of phosphorus, measured in the P2O5 form, is between 3% and 4% by weight, with respect to the total weight of the catalyst,
• the WO3/MoO3 molar ratio is between 5.3 and 12.4 mol/mol,
• the NiO/(WO3+MoO3) molar ratio is between 0.20 and 0.33 mol/mol, and
• the P2O5/(WO3+MoO3) molar ratio is between 0.105 and 0.170 mol/mol.
