Catalytic performance of Rh/SiO2 in glycerol reaction under hydrogen

Author affiliations

Abstract

Glycerol is a main byproduct in the biodiesel production process, and the effective utilization of glycerol can contribute to biodiesel promotion. One of the possible methods is the catalytic conversion of glycerol to valuable chemicals, and this can also agree with the concept of green chemistry in terms of the utilization of renewable resources. Catalytic performance of supported metal catalysts (metal: Rh, Ru, Pt, Pd support: active carbon, SiO2, Al2O3) was evaluated in the reaction of glycerol aqueous solution under H2. It is found that Rh/SiO2 exhibited higher activity and higher selectivity to hydrogenolysis products such as propanediols and propanols than Ru/C catalysts at low temperature (393 K). We also investigated the additive effect of ion-exchange resin (Amberlyst). Regarding the reaction route in the reaction of glycerol, it is suggested that the consecutive hydrogenolysis of propanediols to propanols on Rh/SiO2 can proceed via 1,2-propanediol, while it can proceed on Ru/C via 1,3-propanediol.
