| Abstract: | Using ortho experiment, it was investigated how each one of preparation conditions affected the characteristics of the product when hydrating high reactive calcium based sorbents. Results indicated that time, temperature, Ca(OH) 2/CaSO 4 mass ratio, and fly ash/(Ca(OH) 2+CaSO 4) mass ratio have notable influence on the specific surface area of sorbents. Furthermore, optimal values were obtained by means of single factor experiment. Finally, the components of hydrated production were measured by X ray diffraction , and SEM showed different morphology between fly ash and hydrated sorbents. |
