Influence of the conditions of the carbon supports preparation from an expanded natural graphite and chemically modified anthracites on the formation of carbon porous structure, on the distribution and sizes of supported palladium particles and their catalytic activity in liquid phase reactions of hexene-1 and cyclohexene hydrogenation has been studied. At the same reaction parameters and Pd content the catalytic activity of different samples varies by more than 100 times. Besides, the activity of some catalysts in hexene hydrogenation is much higher (up to 20 times) than that in cyclohexene hydrogenation reaction. The possible reasons for observed differences in Pd catalyst behavior are analysed.
