Promotional effect of transition metals (Cu, Ni, Co, Fe, Zn)–supported on dolomite for hydrogenolysis of glycerol into 1,2-propanediol
Hydrogenolysis of biomass-derived glycerol is an alternative route to produce 1,2- propanediol. A series of transition metals supported on dolomite catalysts (Cu/Dol, Ni/Dol, Co/ Dol, Fe/Dol, Zn/Dol) were prepared via impregnation, calcined at 500 C and reduced at 600 C. The synthesized catalysts we...

Hydrogenolysis of biomass-derived glycerol is an alternative route to produce 1,2- propanediol. A series of transition metals supported on dolomite catalysts (Cu/Dol, Ni/Dol, Co/ Dol, Fe/Dol, Zn/Dol) were prepared via impregnation, calcined at 500 C and reduced at 600 C. The synthesized catalysts were then characterized by BET, BJH, XRD, H2-TPR, NH3– TPD, and SEM, and subsequently evaluated in glycerol hydrogenolysis reaction to produce 1,2- propanediol (1,2-PDO). The nature of transition metals was found to influence the activation of the catalysts. Among the tested catalysts, copper supported on dolomite (Cu/Dol) exhibited appre ciable hydrogenolysis performance due to the mutual interaction between the copper species and the dolomite. The findings from the various characterization results showed the addition of copper to dolomite ameliorates the chemical and reduction of the catalyst.
