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

摘要

The invention concerns a supported catalyst comprising a predominantly calcined aluminium oxide support and an active phase comprising nickel, the nickel content being between 5 and 65% by weight of said element relative to the total mass of the catalyst, said active phase not comprising group VIB metal, the nickel particles having a diameter less than or equal to 20 nm, said catalyst having a mesoporous median diameter of between 8 nm and 25 nm, a macroporous median diameter greater than 200 nm, a mesoporous volume measured by mercury porosimetry greater than or equal to 0.30 mL/g and a total porous volume measured by mercury porosimetry greater than or equal to 0.34 mL/g. The invention also concerns the method of preparing said catalyst and the use of same in a hydrogenation method.
