A series of supported vanadium-titanium denitrification catalysts were prepared by impregnation method with foam metal as carrier for NH 3 -SCR of NO x at low temperature. Effects of pH, slurry concentration, catalyst loading rate, face velocity and O 2 concentration on catalytic performance were studied. The results showed that when immersion concentration was 30g/100mL and filtration speed was 0.7m/min, the pressure drop was 300Pa and NO x removal efficiency was 98% at 200°C. The foam catalytic filter was put into the bag dust collector, which had the function of simultaneous removing particulate and NO x . When filtration velocity was 0.7m/min, NO x removal efficiency reached 95.5% at 200°C and it had good water resistance. The results provided the basis for further pilot experiment.
