Selective hydrogenation catalyst comprising an extruded support

摘要

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