A catalyst composition comprising a uniform dispersion of individual metallic palladium particles, substantially free of clusters of said particles, on and throughout an alumina aerogel support, said composition having a BET surface area in the range of about 20 to about 700 m2/g, a pore volume in the range of about 1.5 to about 12 cm3/g, a bulk density in the range of about 0.003 to about 0.5 g/cm3 and having a Pd DEG /Al2O3 weight ratio of about 1:1000 to about 1:5 is disclosed. A process of preparing the catalyst composition having metallic palladium impregnated on alumina aerogel and a process of using same as a hydrogenation catalyst are also disclosed. |
