ABSTRACT:
The invention provides a nickel/alumina catalyst, with an atomic ratio of nickel/aluminium between 10 and 2, an active nickel surface area between 70 and 150 m.sup.2 /g nickel and an average pore size, depending on the above atomic ratio, between 4 and 20 nanometers. Preferably the nickel/aluminium atomic ratio is between 10 and 4. Preferably the catalyst has a specific porous structure.
The invention also provides a method for preparing the catalyst by a two step process involving precipitating nickel ions and adding during a second, so-called ageing step a soluble aluminium compound.
The catalyst is useful for hydrogenating unsaturated organic compounds in particular oils.
