Experimental study on NO reduction by propane over iron
摘要
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 C3 H8 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 reductoi n 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 di fferecn e in NO er duction 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.关键词
