摘要
以NH3为还原剂的选择性催化还原(SCR)是目前研究最多也是最有效的燃煤烟气NOx脱除技术。活性炭脱硝活性较低,在活性炭上负载金属氧化物能有效提高低温脱硝活性,是近些年来研究的热点。本文主要总结了金属锰、铜、铈和钒的氧化物负载在活性炭上低温脱硝的性能,指出不同负载催化剂在实践上应用的优势和技术上存在的不足,并提出脱硝机理,最后对活性炭负载金属氧化物在低温脱硝中的前景进行了展望。
Selective catalytic reduction(SCR)with NH3 as a reducing agent is currently most effective NOx removal technology for coal-fired flue gas.Activated carbon has low denitration activity,and loading metal oxides on activated carbon can effectively improve the low-temperature denitration activity,which has been a research hotspot in recent years.This article mainly summarized the performance of low-temperature denitration of metal oxides supported on activated carbon,the advantages and disadvantages of different catalysts,and prospects its farther development of activated carbon-supported metal oxides used in low-temperature denitration.
