Abstract

|
|
Development of flue gas desulfurization process is becoming an essential task to be accomplished especially for the power plants and industrial facilities.
This study is to discuss the adsorption characteristics and removal efficiencies of SO₂ by granular activated Carbon, activated carbon impregnated with sodium and cupric oxide supported on zeolite.
The results obtained in the experiment were as follows :
1. Freundlich isothermal predicted single component adsorption is as follows
granular activated carbon logX/M=-3.139＋1.871ogC
activated carbon (impregnated with sodium) logX/M=0.718＋0.89logC
Removal efficiency of SO₂ with the activated carbon impregnated sodium is higher than the activated carbon.
2. Removal efficiency of SO₂ with CuO/zeolite was improved with temperature increase.
3. The reaction rate constant of SO₂ with CuO/zeolite was as follows : k(㎝/s)=2.060exp[ -3307(cal/㏖)lRT]
