Production of CO-rich Hydrogen Gas from Glycerol Dry Reforming Over La-promoted Ni/Al2O3 Catalyst

Production of CO-rich Hydrogen Gas from Glycerol Dry Reforming Over La-promoted Ni/Al2O3 Catalyst

Dry reforming of glycerol has been carried out over alumina-supported Ni catalyst promoted with lanthanum. The catalysts were characterized using EDX, liquid N2 adsorption, XRD technique as well as temperature-programmed reduction. Significantly, catalytic glycerol dry reforming under atmospheric pr...
