The present invention relates to a supported catalyst comprising a calcined, mainly alumina support, and an active phase comprising nickel in a content of 5 and 65% by weight of said element relative to the total mass of the catalyst, said active The phase does not contain Group VIB metals, the nickel particles have a diameter of less than or equal to 20 nm, the catalyst has a median diameter of the mesopores of greater than or equal to 14 nm, and greater than or equal to 0.45 mL/g as measured by mercury porosimetry Mesopore volume, total pore volume measured by mercury porosimetry greater than or equal to 0.45 mL/g, macropore volume less than 5% of total pore volume, the catalyst being of particles having an average diameter of 0.5 to 10 mm form. The present invention also relates to a process for the preparation of said catalyst and its use in a hydrogenation process. |
