Abstract: A selective hydrogenation catalyst contains an active phase having a group VIB metal and a group VIII metal, and a porous support containing alumina. The group VIB metal content is between 1 and 18% by weight relative to total weight of the catalyst, and the group VIII metal content of the active phase, measured in oxide form, is between 1 and 20% by weight relative to total weight of the catalyst. The molar ratio between the group VIII metal and the group VIB metal is between 1.0 and 3.0 mol/mol. The group VIII metal is homogeneously distributed in the porous support with a distribution coefficient R of between 0.8 and 1.2, measured using a Castaing microprobe, and the group VIB metal is distributed at the periphery of the porous support with a distribution coefficient R of less than 0.8.
