A V_2O_5-TiO_2 ceramic filter with catalytic function was prepared by loading TiO_2 carrier and active denitration components on the ceramic filter using sol-gel method.Moreover

the prepared ceramic catalytic filter was characterized by SEM

XRD and BET.Without considering the effect of fly ash particles

the deNOxperformance of the ceramic catalytic filter was studied in the simulated flue gas.The effects of several factors on denitration performance of the ceramic catalytic filter were also investigated

such as the loading times and capacity

V_2O_5 load capacity

surface velocity and mole ratio of ammonia to nitrogen.The results indicated that

the catalyst dispersed uniformly in the ceramic filters.One time loading of the TiO_2carrier(mass fraction of TiO_2 is 3%)can obtain the maximum specific surface area for the filter

which is advantageous to loading active components.At 340℃

with flue gas flow rate of 0.5L/min and V_2O_5 mass fraction of 10%

the ceramic filter's denitration activity could reach up to 80%

which is the highest.This conclusion provides basis for further study and optimization for ceramic filter supported denitration catalyst.
