低温NH3-SCR催化剂抗水抗硫性能研究进展OA北大核心CSTPCD

Aiming at the problem of catalyst poisoning in low-temperature with selective catalytic reduction with ammonia(NH3-SCR)by H2O and SO2 in flue gas,this article reviews the methods for improving the water-and sulfur-resistance of low-temperature NH3-SCR catalysts from three aspects:preparation methods,carrier types,and structure and morphology control,deeply explores the relationship between the structural and morphology of catalysts and their water-and sulfur-resistance performance,and introduces new ideas for the design and preparation of low-temperature NH3-SCR catalysts in details.It is pointed out that research on the structure and morphology control of low-temperature NH3-SCR catalysts should be strengthened in the future.
