炭基负载 V2 O5脱硝催化剂低温脱硝性能
Low-temperature SCR reactivity of the activated Carbon-supported vanadium oxide catalyst
摘要
Abstract
Effects of reaction conditions on low-temperature SCR activity of the activated carbon-supported vanadium oxide (V2 O5/AC)catalyst were investigated in a fixed bed reactor.The results suggest that, compared with AC,the NO adsorption capacity of V2 O5/AC was enhanced a little while the NH 3 adsorp-tion capacity was significantly enhanced.The prepared V2 O5/AC catalyst had approximately 90% NOx re-duction rate at 250 ℃ and 36 000 L/(kgh)space velocity.Raising the temperature could promote the SCR process,but the ablation of AC was also accelerated.The SCR reactivity declined when H 2 O was add-ed into the simulated flue gas.Results of the transient response test suggest that O2 was essential to the SCR reaction.关键词
