A process for the preparation of a catalyst comprising palladium, a porous support with a specific surface area in the range 140 to 250 m/g, said catalyst being prepared by a process comprising the following steps:

Method for preparing a selective hydrogenation catalyst

A catalyst comprising palladium, a porous support comprising at least one refractory oxide selected from the group constituted by silica, alumina and silica-alumina, the palladium content in the catalyst being in the range 0.01% to 2% by weight with respect to the total catalyst weight, at least 80% by weight of the palladium being distributed in a crust at the periphery of said support, the thickness of said crust being in the range 20 to 100 &#x3bc;m, characterized in that said support is in the form of an extrudate and in that said support comprises a specific surface area in the range 165 to 250 m/g.

Selective hydrogenation catalyst comprising an extruded support

A catalyst comprises an active phase constituted by palladium, and a porous support comprising at least one refractory oxide selected from the group constituted by silica, alumina and silica-alumina, in which:
