Glycerol Dry Reforming Over Alumina-Supported Nickel Catalysts

In this paper, dry (CO2)-reforming of glycerol, a new reforming route was carried out over alumina (Al2O3)-supported non-promoted and lanthanum-promoted Ni catalysts. Both sets of catalysts were synthesized via wet co-impregnation procedure. The physicochemical characterization of the catalysts show...
