| Abstract: | An optimization method was presented for selecting the process parameters of the preparation of Ca-based sorbent from hydration of Ca(OH)2, CaSO4 and fly ash. Based on uniform design of experiments and regression analysis algorithm, a second order mathematical model was developed to correlate the absorbent preparation variables to the BET specific surface area (SSA) of the sorbent. The predicted SSA was found to agree satisfactory with the experimental values. The effect of various absorbent preparation variables such as hydration temperature , amount of fly ash, amount of CaSO4, water-solid ratio and hydration time on SSA of the sorbent were investigated. The SSA of the sorbent which prepared under the optimal conditions was over 120 m2/g and ten times higher than crude Ca(OH)2. |
