摘　　要：目前,传统商业SCR催化剂在火电脱硝行业中的应用相对成熟,但在烟气温度低且组分复杂的非电行业中,该催化剂存在易中毒、低温性能差、水热稳定性差、氨逃逸高、寿命短等缺点。因此,文章通过对不同催化剂材料进行改性、生产工艺进行改进,制备出低温活性高、水热稳定好、氮气选择性高、氨逃逸稳定、抗中毒能力强的多组分复合型低温SCR脱硝催化剂。At present,the application of traditional commercial SCR catalyst in the thermal power denitration industry is relatively mature,but in the non-electric industry with low flue gas temperature and complex components,the catalyst has some shortcomings such as easy poisoning,poor low temperature performance,poor hydrothermal stability,high ammonia escape,and short life.Therefore,by modifying different catalyst materials and improving the production process,this paper prepared a multi-component low-temperature SCR denitration catalyst with high low temperature activity,good hydrothermal stability,high nitrogen selectivity,stable ammonia escape and strong anti-poisoning ability.
