Development of Co–CeO2 catalyst for high temperature water–gas shift reaction |
| 초록 |
Co–CeO2 catalyst prepared by co-precipitation method was applied in high temperature water–gas shift (HT–WGS) reaction. The catalyst showed stable activity performance at 400 °C with 90% CO conversion without any side reaction (methanation) at a very high GHSV of 143,000 h-1, which is the highest value reported for the HT–WGS reaction. Superior reducible nature of ceria support and the preferential exposure of (220) and (112) facets of CeO2 and Co3O4 were responsible for the remarkable performance of the prepared catalyst. The time-on-stream study result substantiates that ceria stabilizes the surface area of Co–CeO2 catalyst during the WGS reaction compared to the bulk Co3O4. |
