The gas-phase hydrogenation of benzene was studied on a series of nickel catalysts supported on alumina-aluminum phosphate (AAP), magnesia-alumina-aluminum phosphate (MgAAP), SiO/sub 2/, and kieselguhr. Measurements of the reaction rates at 110/sup 0/C 3.5 atm, and GHSV = 42,000 showed the phosphate-supported Ni catalysts to be less active than catalysts supported on SiO/sub 2/ or kieselguhr. Additionally, the relative rate on Ni/MgAAP was dependent on the reduction temperature employed during pretreatment. Comparison of the hydrogenation rates and the sulfur capacity toward thiophene poisoning versus the irreversible hydrogen uptake of the various catalysts indicated that the reduced activity of phosphate-supported Ni was due to metal-support effects and that only sites which exhibited strong hydrogen chemisorption were active for benzene hydrogenation.
