摘要：
Catalyst comprising a nickel-based active phase and an alumina support, characterized in that:
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 between 40% and 80% by weight of nickel element relative to the total weight of nickel contained in the catalyst.
