Al2O3 Modifying Ni/TiO2 Catalysts over CH4 Dry Reforming
Addition of aluminum to Ni/TiO2 improves the stability of the catalyst in CH4 dry reforming . The resulting Ni/TiO2 -Al2O3 xerogel, after calcinations at 973K for 10 h, had a BET surface area in excess of 363m2/g, contained mesoprores in the range 2.5 ~2.7nm. Nitrogen adsorption and X - ray diffraction were used to characterize the function of addition aluminum to Ni/TiO2 catalyst. The role of aluminum addition promotes the formation of large metallic Ni ensembles increase the dispersion of Ni, suppression of Ni/TiO2 - Al2O3 catalyst deactivation and carbon deposition.
