NO reduction by ammonia via an FeSO4 catalyst
FeSO4催化剂模块的制备及对其脱硝性能影响的研究

This paper focuses on the NO reduction by ammonia via zeolite-supported FeSO4 catalyst in a fixed-bed reactor under 400°C. The tested flue gas flow rate and space velocity were set at 3,000 ml/min and 1,140,000 m3/h respectively. The experimental results indicate that the catalyst have immediate catalytic effect on NO reduction. Zeolite-supported FeSO4 Catalyst could improve 20% more NO reduction. The preparation conditions, such as supporting material, impregnating solution and preparation time, and the corresponding catalytic activities are investigated.
