Title
Selective hydrogenation of acetone in the presence of benzene
Abstract

•Competitive hydrogenation of acetone and benzene has been studied over metal catalysts.•Selectivity to CO bond hydrogenation increases in the following order: Ni < Pt < Cu.•Selectivity to isopropanol is higher on Cu/SiO2 than on Cu/Al2O3.•Cu/SiO2 with 11 wt.% shows 100% selectivity at 91% conversion of acetone.

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 (2.5 MPa) 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 11 wt.% of copper at 170 °C and 2.5 MPa.
