• Novel dynamic equipment with gas in and out continuously was developed to study the capture capacity of CO sub(2). Municipal solid waste incineration (MSWI) fly ash has a high capture rate of CO sub(2) in CO sub(2)-rich gas. Fly ash can sequester pure CO sub(2) rapidly, and its capacity is 16.3 g CO sub(2)/100 g fly ash with no water added and 21.4 g CO sub(2)/100 g fly ash with 20% water added. For simulated incineration gas containing 12% CO sub(2), the capture rate decreased and the capacity was 13.2 g CO sub(2)/100 g fly ash with no water added and 18.5 g CO sub(2)/100 g fly ash with 20% water added. After accelerated carbonation, the C and O contents increased, indicating CO sub(2) capture in the fly ash; CO sub(2) combines with Ca(OH) sub(2) to form CaCO sub(3), which increased the CaCO sub(3) content from 12.5 to 54.3%. The leaching of Pb markedly decreased from 24.48 to 0.111 mg/L.
