STUDY ON SMALL-SCALE COMMERCIAL TEST OF DENITRIFICATION CATALYST MODIFIED BY FLY ASH

SUN Xu-guang,Yao Qiang,Guo Lu-yang  
The denitrification performance of catalyst modified by fly ash,as well as affecting factors,such as NH_3/NO_x ratio,air velocity,gas temperature etc.have been tested and analysed on small-scale commercial test stand,and the activity of said catalyst after long term positioned in environment of industral operation being investigated.The results of small-scale commercial test show that the said catalyst has good activity of denitrification.Under condition of air velocity to be 5200/h,reaction temperature 320 ℃,NH_3/NO_x molar ratio 1.2,the efficiency of denitrification can reach above 90%,at the same time,the activity of said catalyst positioned in environment of industrial operation for more than one year hasn't obviously reduced,maintaining about 90% from begining to end.
