Effect of Different Metal Modified Dolomite Catalysts on Catalytic Glycerol Hydrogenolysis towards 1,2-Propanediol

A series of metal modified dolomite catalysts (10%Ni-20%Cu/Dol, 10%Co-20%Cu/Dol, 10%Fe-20%Cu/Dol, 10%Zn-20%Cu/DolNi) were synthesized via method of impregnation, later calcined at 500 °C and reduced by 5%H2 at 600 °C. Those catalysts were formerly tested for their physico-chemical properties by BET,...
