Hydrogen productions from ethanol steam reforming on Ni and Mn core@shell-structured Ni-Mn@SiO2 catalysts |
| 초록 |
To improve the catalytic stability during ethanol steam reforming (ESR), this study considered the role of the redox promoter of the Mn component in a Ni-based catalyst and the stability of the core@shell structure. Five different core@shell NiMn@SiO2 catalysts were applied to the ESR reaction. The hydrogen selectivity was highest on the Ni8.5Mn1.5/SiO2 catalyst. During ESR, the amount of evolved CO gas, is related to catalyst deterioration, was large over the Ni@SiO2 catalyst, but it was relatively low on the NiMn@SiO2 catalysts. The amounts of carbon deposited were smallest over the Ni8.5Mn1.5/SiO2 catalyst. As the results of CH4-, CO- and H2O-TPD, the CH4 and CO molecules were adsorbed predominantly on the surface of Ni, but H2O molecules were absorbed easily on the surface of the Mn sites, leading to a CO to CO2 transformation through a water gas shift reaction. |
