Regenerable Sodium-Based Sorbents for CO2 Capture at Middle Temperatures |
| 초록 |
A regenerable sodium-based sorbent (Na(P)) was developed for CO2 capture in IGCC(Integrated Gasification Combined Cycle) at middle temperatures range (200~400 oC).The sorbent was prepared by the physical mixing of sodium carbonate with some special support. The Na(P) sorbent adsorbed CO2 at 210 oC and it was regenerated easily at 350 oC. The Na(P) showed an excellent CO2 capture capacity of 60 mg CO2/g sorbent at the first cycle. By deactivation, the CO2 capture capacity was decreased to 33 mg CO2 /g sorbent and this capacity was maintained for repeated experiments. The excellent CO2 capacity was due to the active alloy material formed from sodium and special support (P). These results were discussed through the analysis of XRD patterns. |
