Effect of alkali and alkaline earth metal on Co/CeO2 catalysts for the water-gas shift reaction of waste derived synthesis gas |
| 초록 |
We prepared a series of alkali (Na and K) and alkaline earth metal (Ca and Ba) promoted Co/CeO2 catalysts to investigate the effect of the promoter on the catalytic performance of the catalyst in the high-temperature water-gas shift (WGS) reaction of waste derived synthesis gas. Alkali and alkaline earth metal enhanced the catalytic performance of Co/CeO2 in a different side; alkali metal increased catalytic activity, whereas alkaline earth metal strengthened catalytic stability. Especially, alkaline earth metal-promoted catalysts showed stable performance (＞ 50 h, ＞ 85% CO conversion) even at a very high gas hourly space velocity of 143,000 h-1. The excellent activity and stability of the alkaline earth metal-promoted catalysts was due to the strong resistance to sintering induced by the interaction between cobalt and alkaline earth metal promoter, and high oxygen vacancy concentration. |
