氮氧化物选择性催化还原催化剂研究

Study on Catalyst for Selective Catalytic Reduction of Nitrogen Oxide

选择性催化还原(SCR)技术是研究最多、应用最广的烟气NO_x脱除技术,该技术的关键是催化剂的研发,其催化性能直接影响到脱硝效果的好坏。该研究介绍了SCR领域研究开发的以贵金属、金属氧化物、碳材料为载体的低温脱硝催化剂,并对碳纳米材料催化剂做了重点介绍,最后对今后的研究方向进行展望。

Selective catalytic reduction （SCR） technology is the most widely used technology for removal of flue gas NOx. The key of this technology is research and development of catalyst, and the catalytic performance directly affects the effect of denitrification. Low temperature denitrification catalyst with precious metals, metal oxides, and carbon materials as carriers in the SCR field was introduced, and carbon nano materials catalyst was studied, finally research direction in the future was.forecasted.
