Abstract

Abstract

NO reduction by propane over iron was experimentally investigated in a one-dimensional temperature-programmed ceramic tubular reactor at 300~1 100 ℃ in N₂ and simulated flue gas atmospheres. The NO reduction efficiencies by C₃H₈ over iron were compared to that by methane. The results show that propane can effectively reduce NO to N₂ over metallic iron. In N₂ atmosphere, the NO reduction efficiency by propane over metallic iron is higher than that by methane at 500~900 ℃. More than 95% of NO is reduced by propane over metallic iron when the temperature is above 900 ℃, which is very close to that by methane. In simulated flue gas atmosphere, when the excessive air ratio is lower than 1.0, NO reduction by propane over iron exceeds 90% when the temperature is above 900 ℃. There is little difference in NO reduction whether there is a burnout for propane. At same conditions, NO reduction by propane over iron is higher than that by methane. The effect of SO₂ on NO reduction by propane over iron is rather small and can be ignored.
