Patent ID: 10618033

Abstract:
The invention relates to a supported catalyst that comprises an oxide substrate that is for the most part calcined aluminum and an active phase that comprises nickel, with the nickel content being between 5 and 65% by weight of said element in relation to the total mass of the catalyst, with said active phase not comprising a metal from group VIB, the nickel particles having a diameter that is less than or equal to 20 nm, said catalyst having a median mesopore diameter of between 8 nm and 25 nm, a median macropore diameter of greater than 200 nm, a mesopore volume that is measured by mercury porosimetry that is greater than or equal to 0.30 mL/g, and a total pore volume that is measured by mercury porosimetry that is greater than or equal to 0.34 mL/g. The invention also relates to the method for preparation of said catalyst and its use in a hydrogenation method.
