The Catalysts Performance of [Bmim]₆PMO₉V₃O₄₀/ACF on Flue Gas Desulfurization

Abstract:

The supported [Bmim]₆PMo₉V₃O₄₀ was synthesised by using the ion liquid [Bmim]Cl and heteropoly acid H₆PMo₉V₃O₄₀, and was supported on the active carbon fibre.The results of FT-IR showed that the structure of Ionic liquid cation and anion heteropoly acid on the active carbon fibre did not changed during the synthesising and supporting of the [Bmim]₆PMo₉V₃O₄₀. The catalysts performance of [Bmim]₆PMo₉V₃O₄₀/ACF on Flue Gas Desulfurization was investigated. The investigation was focused on the influence of the capacity of [Bmim]₆PMo₉V₃O₄₀, the oxygen centent, and reaction temperature on [Bmim]₆PMo₉V₃O₄₀/ACF for flue gas desulfurization. The experimental results showed that the desulfurization rate was up to 100%, lasting for 100 minutes,the sulfur capacity was as high as 400 mg/g in 4h, as desulfurization codition for the oxygen centent of 8% and the temperature of 60°C.
