摘　　要：针对FCC装置再生烟气脱硝,采用共沉淀法将过渡金属掺杂于TiO_(2)载体上制备V_(2)O_(5)-WO_(3)/TiO_(2)脱销催化剂,考察过渡金属对V_(2)O_(5)-WO_(3)/TiO_(2)催化剂脱硝性能的影响。结果表明,载体掺杂Ce制备的催化剂催化活性最好,NO最高转化率达99%。V_(2)O_(5)-WO_(3)/TiO_(2)catalyst modified by transition metals doped into TiO_(2)carrier was prepared by coprecipitation for denitrification of regenerated flue gas from FCC unit.The effect of transition metals on the denitrification performance of catalyst was investigated.The results showed that Ce doping catalyst had the best activity with 99%conversion of NO.
