1. A catalyst comprising nickel and sulfur on an alumina support, said catalyst comprising 5% to 25% by weight of elemental nickel relative to the total weight of the catalyst, between 0.05% and 10% by weight of elemental sulfur relative to the total weight of said catalyst, said catalyst having the following characteristics:
the nickel is distributed both on a crust at the periphery of the support, and in the core of the support, the thickness of said crust being between 2% and 15% of the diameter of the catalyst;
the nickel density ratio between the crust and the core is strictly greater than 3;
said crust comprises more than 25% by weight of nickel element relative to the total weight of nickel contained in the catalyst,
wherein the nickel in the catalyst is in the form of particles, and wherein the size of the nickel particles in the catalyst, measured in oxide form, is between 7 and 25 nm.
