| Abstract: | The structure identification and carbonation characteristics of several potassium-based supported sorbents for CO2 capture were investigated with TGA,XRD,XRF,SEM and N2 adsorption method.Potassium-based sorbents were prepared by impregnation with potassium carbonate on supports,such as cocoanut activated charcoal(AC1),coal active carbon(AC2),silica gel(SG)and diatomite(DT)using the iso-volume impregnation method.The results showed that the K2CO3 loading amounts of AC1,AC2,SG and DT were 24.1%,22.5%,21.7% an... |
