MESOPOROUS AND MACROPOROUS CATALYST MADE FROM NICKEL HAVING A MACROPOROUS MEDIAN DIAMETER OF BETWEEN 50 NM AND 200 NM AND USE OF SAME IN HYDROCARBON HYDROGENATION

摘要

A supported catalyst, its method of preparation and use in hydrogenation methods, which catalyst contains an oxide substrate that is for the most part calcined aluminum and an active phase that contains nickel, with the nickel content between 5 and 65% by weight in relation to the total mass of the catalyst, with the active phase not containing a metal from group VIB, the nickel particles having a diameter that is less than or equal to 20 nm, the catalyst having a median mesopore diameter of between 14 nm and 30 nm, a median macropore diameter of between 50 and 200 nm, a mesopore volume that is measured by mercury porosimetry that is greater than or equal to 0.40 mL/g, and a total pore volume that is measured by mercury porosimetry that is greater than or equal to 0.42 mL/g.
