Abstract
The invention concerns a catalyst comprising a calcined oxide matrix which is mainly alumina and an active phase comprising nickel, said active phase being at least partially co-mixed within said calcined oxide matrix which is mainly alumina, the nickel content being in the range 5% to 65% by weight of said element with respect to the total mass of catalyst, said active phase not comprising metal from group VIB, the nickel particles having a diameter of less than 15 nm, said catalyst having a median mesopore diameter in the range 8 nm to 25 nm, a median macropore diameter of more than 300 nm, a mesopore volume, measured by mercury porosimetry, of 0.30 mL/g or more and a total pore volume, measured by mercury porosimetry, of 0.34 mL/g or more. The invention also concerns the process for the preparation of said catalyst, and its use in a hydrogenation process.
