A process for preparing a selective hydrogenation catalyst is described, wherein is provided a catalyst precursor, comprising at least one group VIII metal in the metallic form, and at least one support formed of at least one oxide, characterized in that a step is performed of contacting the said catalyst precursor in the metallic form, in the liquid phase and in the presence of a reducing and/or inert atmosphere, with a non-polar solvent containing a silicon compound, the said silicon compound is selected from the silanes containing at least one Si&#x2014;H bond and at least one Si&#x2014;C bond, the silanols and the cyclic siloxanes. The selective hydrogenation process implementing the said catalyst is also described.
