| 제목 | CO 2 Capture Using Dry Regenerable Sorbents in a Bubbling Fluidized Bed Reactor |
| 초록 | A bubbling bed reactor was used to study CO 2 capture from flue gas using sodium-based dry regenerable sorbents, sorb NX101 which were manufactured by Korea Electric Power Research Institute. A dry sorbent, sorb NX101, is consists of Na 2 CO 3 for absorption and supporter for mechanical strength. CO 2 capture was effective in the lower temperature range of 50-60 oC, while regeneration occurred in the range of 120-300 oC. To increase initial CO 2 removal, some amount of steam was absorbed in the sorbents before injecting simulated flue gas. CO 2 capture of as much as 100 % was possible for 3-4 min at reaction temperature of 50 oC with stream pretreatment. Little or no reduction in initial reaction rate and capture capacity was observed in multicycle tests. The carbonated and regenerated sorbents were analyzed by NMR to confirm the extent of reaction. The results obtained in this study can be used as basic data for the design of a CO 2 capture process of a large scale with two-fluidized bed reactors. |
