Hydrogenolysis of glycerol to propylene glycol was performed over binary and ternary metal oxide catalysts. The conversion of glycerol and selectivity to propylene glycol were increased on Cu/Zn and Cu/Cr mixed oxides compared to pure CuO and ZnO oxides. The addition of alumina into Cu/Zn mixed oxide very highly increased the conversion of glycerol and selectivity to propylene glycol. The conversion of glycerol was increased with increasing the reaction temperature but the selectivity to propylene glycol was shown to have maximum value at 200 ℃ and then decreased at 250 ℃. The conversion of glycerol and selectivity to propylene glycol were decreased with increasing the glycerol concentration.
