Characterization of potassium-based sorbents using metal oxides or metal silicates for post-combustion CO2 capture |
| 초록 |
Potassium sorbents for capturing CO2 in a fast fluidized bed reactor should have high CO2 capture capacities, good regeneration properties and high abrasion resistances. Therefore, several studies had focused on the development of the potassium-based solid sorbents using various supports. In this study, the CO2 sorption and regeneration characterization of the sorbents using metal oxides or metal silicates as a support were investigated. CO2 sorption and regeneration properties were investigated in a fixed bed reactor at low temperature ranges of 60–200 °C. In addition, structural changes of the sorbents were investigated by powder X - ray diffraction (XRD) and the regeneration characteristics were analyzed by thermogravimetric analysis (TGA). The CO2 capture capacities of the sorbents using metal silicates as a support show approximately 96 mg CO2/g sorbent. In addition, their regeneration ratios were 100%. |
