Abstract
Steam reforming (SR) of glycerol for the production of hydrogen was investigated over the nano-sized Ni-based catalysts. The Ni-based catalysts were prepared by a solid phase crystalization and impregnation methods, and characterized by N2 physisorption, CO chemisorption, XRD, TPR, SEM, and TEM techniques. The Ni/γ-Al2O3 catalyst showed higher conversion and H2 selectivity. However, it was slowly deactivated due to carbon formation on the surface of catalyst and the sintering. It was found that the Ni based hydrotalcite catalyst showed higher catalytic activity with the restriction for carbon formation than Ni/γ-Al2O3 catalyst in the SR of glycerol.
