【Abstract】 Activated carbon fiber（ACF） felt was impregnated under the following condition: impregnating solution containing 1.96%（mass fraction） NH₄VO₃,0.68%（mass fraction） CsVO₃,impregnating temperature 70 ℃,20 g ACF impregnated in 1 250 mL impregnating solution for three times with six hours each time.The impregnated ACF was then calcined in nitrogen atmosphere at 250 ℃ for 50 minutes,and cooled down to room temperature to obtain ACF catalyst.Properties of the ACF catalyst for flue gas desulfurization was tested on a simulation bench-scale apparatus.The test results showed that activity of the ACF felt catalyst of flue gas desulfurization were as follow: KI-ACF>V₂O₅-Cs₂O-ACF>air-ACF. Kinetic equation for flue gas desulfurization over V₂O₅-Cs₂O-ACF catalyst was dc_SO2dt=0.072exp（7.843×10³RT）c^1.025_SO2·c^0.579_O2, obtained under the following condition: 348 K,0.225 mol·m^-3 SO₂ in flue gas,GHSV(2 400 h^-1.)更多还原
