Pt and Ceria Promoted Ni/SBA-15 for <em>n</em>-Dodecane Steam Reforming for Hydrogen Production

Related Articles

Abstract Ni supported on SBA-15 was prepared via ethylene-glycol-assisted impregnation method and the performance of the as-prepared catalyst was tested by n-dodecane steam reforming. Pt and CeO₂ used as promoter and reaction condition affected the performance of Ni/SBA-15 in n-dodecane steam for hydrogen production. Various techniques including nitrogen adsorption-desorption, H₂-TPR, TEM, XRD, and TG/DTG were employed to characterize the fresh and spent catalysts. Results show that the Pt and CeO₂ used as promoter could enhance the dispersion of Ni. Pt promoted Ni/SBA-15 could reduce the reduction temperature, thus increase the activity and stability for n-dodecane steam reforming. Pt and CeO₂ co-promoted Ni/SBA-15 showed the complete conversion of n-dodecane and was stable for hydrogen production (5 200 μmol/min).
