The competitive hydrogenation of acetone and benzene has been studied over Ni/SiO₂, Pt/SiO₂, Ru/SiO₂ and copper containing catalysts: Cu/SiO₂ with different copper content, Cu/Al₂O₃, copper chromite containing catalyst (CuCr₂O₄×CuO). The catalysts were characterized by elemental analysis, X-ray diffraction, TEM, TPR of hydrogen and low-temperature adsorption of nitrogen. The catalytic experiments were carried out in a fixed bed reactor under atmospheric and elevated (2.5MPa) pressure, in the temperature range of 130–250°C. Cu-containing catalysts showed the highest selectivity to acetone hydrogenation in the presence of benzene. The best results in terms of activity and selectivity to isopropanol were obtained over Cu/SiO₂ with 11wt.% of copper at 170°C and 2.5MPa.
