The effect of supports (Al2O3, Al2O3-TiO2, SiO2, SiO2-TiO2 and TiO2) on hydrogenation activity of nickel and platinum catalysts has been studied. The Ni and Pt content of the samples was fixed at 5 wt.% and 0.5 wt.% respectively The deposition of TiO2 on surface of both Al2O3 and SiO2 supports increases hydrogenation activity of the catalysts. A comparison of activity of the Ni/Al2O3-TiO2 and the Ni/SiO2-TiO2 catalysts proved that the SiO2-TiO2 supports are better both for use of nickel and platinum catalysts. Pt/SiO2-TiO2 catalysts exhibited high catalytic activity in the hydrogenation of toluene at lower temperature range.
