CATALYST COMPRISING PALLADIUM AND SELECTIVE HYDROGENATION APPLICATION THEREOF |
摘要 |
The invention relates to a catalyst comprising a porous support, palladium and at least one metal chosen from the group composed of alkali metals and alkaline-earth metals, in which: -the specific surface area of the porous support is between 50 and 210 m2/g, -the palladium content in the catalyst is between 0.05 and 2 wt%, -at least 80 wt% of palladium is distributed in a crust on the periphery of the support, the thickness of said crust being between 20 and 200 µm, -the metallic dispersion D is between 25% and 70%, -the density of palladium particles in the crust is between 1500 and 4100 palladium particles per µm2 -and said alkali metal and/or alkaline-earth metal is uniformly distributed throughout the support. The invention also relates to the preparation of the catalyst and the use thereof in selective hydrogenation. |
