Mo/γ-Al₂O₃-MgO as a Bifunctional Catalyst for Renewable Hydrogen Production from Steam Reforming of Glycerol

Abstract:

In this paper the catalytic steam reforming of glycerol to H2 has been evaluated in the presence of Mo/γ-Al2O3 and Mo/γ-Al2O3-MgO in a fixed-bed microreactor at 700 oC. Physiochemical properties of the Mo catalysts were explored by various analytical techniques such as N2 adsorption–desorption (BET), X-ray diffraction (XRD), X-ray fluorescence spectrum (XRF), Temperature-programmed reduction (TPR) and Transmission Electron Microscopy (TEM). Mo/γ-Al2O3-MgO catalysts show promising results with higher H2 concentration produced as compared to Mo/γ-Al2O3 catalysts. The Mo was found to be uniformly distributed on the surface of γ-Al2O3-MgO support and addition of MgO contents into γ-Al2O3 improves the dispersion of Mo on the surface of the support.
