Abstract:In this paper,fine,high activation hydrated lime was obtained by means of optimizing experimental conditions during sorbent preparation. Factors influencing specific surface area,include additive weight percentage, CaO particle size, CaO weight, reaction temperature, reaction time and Fe-additive molar fraction. On the basis of prepared sorbent,physico-chemical characterizations, such as SEM(Scan Electronic Microscopy) ,EDAX and particle size distribution were studied. Furthermore . the SO2 adsorption performance of sorbent on the thermogravimetric balance was discussed.
Keywords:sorbent  specific surface area  SEM  EDAX  particle size distribution  reaction kinetics
