Abstract

Fe-based ionic liquid(Fe-IL) was synthesized by mixing FeCl

·6H

O and 1-butyl-3-methylimidazolium chloride [Bmim

]

Cl in this paper.The phase diagram of a ternary Fe-IL

ethanol and water system was investigated to construct a ternary desulfurization solution for wet flue gas desulfurization.The effects of flow rate and concentration of SO

reaction temperature

pH and Fe-IL fraction in aqueous desulfurization solution on the desulfurization efficiency were investigated.The results shows that the best composition of ternary desulfurization solution of Fe-IL

ethanol and water is 1:1.5:3 by volume ratio

and pH should be controlled at 2.0.Under such conditions

a desulfurization rate greater than 90% could be obtained.The product of sulfuric acid had inhibition effect on the wet desulfurization process.With applying this new ternary desulfurization solution

not only the catalyst Fe-IL can be recycled and reused

but also the product sulfuric acid can be separated directly from the ternary desulfurization system.
