The hydrogenation of cyclohexene over Pt catalysts supported on alumina, activated carbon, and aluminum borate is investigated in a liquid phase batch reactor at a temperature of 60-degrees-C and a hydrogen pressure of 1 atm. The dispersion of Pt metal on these catalysts was determined by hydrogen adsorption in gas volumetry. Under the conditions employed in this study, the aluminum borate-supported catalyst was found to possess the highest activity. This can be attributed to its high metal dispersion and high turnover frequency.
