摘要

制约我国燃煤NOx排放控制的主要因素是用于选择性催化还原(SCR)的催化剂成本和潜在的重金属二次污染问题。为此

分别论述了用于氨和轻烃选择性催化还原NOx的金属氧化物、金属离子交换沸石、钛柱撑粘土、Al2O3担载重金属、稀土氧化物等催化剂的研究进展

包括催化剂的选择原则、反应机理、催化活性及活性温度区间、烟气中HO和SO的影响等

总结了进一步改进催化活性的方向。

Abstract

The main factors restricking the application of Selective Catalytic Reduction (SCR) technology in China to control NOx emission are the problems of catalyst cost for SCR denitrification and the potential secondary pollution of heavy metalls.For this reason

the research achivements for catalysts of SCR denitrifucation by NH3 and hydrocarbon have been expounded respectively

such as metal oxides

metal ion exchanged zeolites

titanium pillared clay

Al2O3 supported heavy metalls

and rare earth oxides catalysts

and including principles of selecting a suitable catalyst

reation mechanism

catalytic activity

temperature range of activity

and effects of H2O and SO2 in the flue gas etc.

and direction for further improving catalytic activities being proposed.
