| Abstract: | The solid amine sorbents were prepared with Al-rich fly ash by using wet gel impregnation method for CO2 capture. In order to obtain the sorbents with the highest CO2 sorption capacity, the parameters of preparation process was optimized by using the 6 sigma method. The sorbents were also characterized. The effects of polymer molecular weight, polymer loading amount and reaction temperature on CO2 sorption capacity were investigated. The CO2 sorption capacity was evaluated by using thermogravimetric analyzer. The best sorbent gave a high sorption capacity of 160 mg-CO2·g-sorbent-1, which is much higher than those from previously published literatures for sorbent obtained from fly ash. The results indicate that the sorbent synthesized by this environmentally friendly and cost effective method has potential application for low temperature CO2 capture in terms of its outstanding features such as high capture capacity, fast sorption/desorption rate, no corrosive and cost-effective. |
