A series of carbon-supported Pt catalysts prepared using different precursors and methods and covering a wide range of metal dispersion (0.08-0.51) have been studied in the reaction of n-butane with hydrogen. These are basically hydrogenolysis catalysts in which the splitting of the terminal C-C bond predominates. The hydrogenolysis of n-butane is a reaction sensitive to the structure of the catalysts, whereas this is not the case for isomerization. The selectivity for hydrogenolysis increases with decreasing mean Pt particle size. The apparent activation energies for the two reactions (larger for isomerization) are independent of particle size.
