Nitrogen Oxide (NO_x) in stationary flue gas is a major contribution to air pollution and its reduction is thus of great importance. Vanadium pentoxide,V₂O₅ catalyst was deposited on woven stainless steel wire mesh (WSSWM) to examine NO_x reduction in solid waste incinerator flue gas. The WSSWM was initially coated with an alumina/silica (Al₂O₃-SiO₂) mixture using the dip-slurry method. Wet impregnation of the catalyst was achieved by using V₂O₅ precursor solutions of concentration 0.2, 0.4 and 0.6 M followed by calcination process for 48 hours at 500°C. The prepared catalyst is termed as V₂O₅/Al₂O₃-SiO₂. NOx reduction activity of V₂O₅/Al₂O₃-SiO₂ was performed on the in-house bench scale municipal solid waste incinerator (BS-MSWI) by using cafeteria waste combustion to simulate NO_x emission. The NO_x conversion was evaluated based on flue gas temperature at operating air flow rate of 100, 150 and 200 ℓ/min respectively. The maximum NO_x reductions of 82.1, 87.8 and 88.7% were achieved at 400°C and with an air flow rate of 200 ℓ/min for precursor catalyst concentrations of 0.2, 0.4 and 0.6 M, respectively.
