Abstract:

Series of alkali and alkaline earth promi=oted palladium-alumina (Pd/Al2O3) catalysts were synthesised by incipient wetness method using palladium acetate dissolved in acetonitrile as a precursor for palladium. The palladium dispersion on the catalyst surface was calculated from the chemisorption of the CO molecule. The synthesised catalysts were tested under the vapour phase for the hydrogenation of phenol to cyclohexanone in a down-flow reactor at atmospheric pressure. Among the samples tested, the alkali metal-promoted catalysts showed better phenol activity. A direct correlation ship was observed between the hydrogenation activity and the functionalities of the promoters were observed.

Keywords:
