Regenerable Sodium-Based Sorbents for CO2 Capture atMiddle Temperatures |
| 초록 |
A novel sodium-based sorbent (NZA85) was developed for CO2 capture at middle temperature range between 200 and 400oC. The CO2 capture and regeneration properties of sodium-based sorbents were measured in a fixed bed reactor at the temperature conditions (CO2 capture at 200oC and regeneration at 400oC) at 1 atm. The sorbent was prepared by the physical mixing of sodium carbonate with zirconium oxide. The NZA85 sorbent showed an excellent CO2 capture capacity of about 100 mg CO2/g sorbent at the first cycle. However, the CO2 capture capacity of the sorbent was decreased to about 40 mg CO2 /g sorbent at the second cycle. After 2 cycles, the CO2 capture capacity was maintained during he multiple tests. The excellent CO2 capture capacity of sodium-based sorbent was due to the structure effect of active alloy material formed during the preparation of the sorbent. These results were discussed through the analysis of XRD patterns. |
