The effect of support for single stage water-gas shift (WGS) reaction over Pt catalysts |
| 초록 |
Various supported Pt catalysts have been applied for single stage water-gas shit reaction (WGS). CeO2, ZrO2, CeO2ZrO2, MgO, MgO-Al2O3 (MgO = 30 wt.%) and Al2O3 were employed as supports for the target reaction in this study. Commercial high temperature shift (HTS) catalyst (Fe-Cr) was also tested as a reference catalyst. Pt/CeO2 exhibited the highest CO conversion as well as very high CO2 selectivity. The high activity and selectivity is due to beneficial effect of CeO2 such as high surface area, redox property and high oxygen storage capacity (OSC). Therefore, CeO2 can be a promising support for single stage WGS. |
