Performance Study f V2O5/TiO2 Mixed Metal Oxide Nanocatalysts in Selective Catalytic Reduction of Nox Prepared by Co-Precipitation Method

摘要

In this work, the selective catalytic reduction of NO with NH3 in the presence of oxygen over a series of Vanadia-Titania was investigated. Catalysts prepared by Co-precipitation method with oxalic acid. Response surface methodology involving central composite design was employed to model and optimize the catalyst preparation parameters of (V loading, calcination temperature, and Co-precipitation temperature) in Selective catalytic reduction of NO at 300 C. Results show that RSM model is able to predict NO conversion data with an acceptable level of accuracy (R2=0.995). The optimum conditions for V loading, Calcinations Temperature, and Co-precipitation temperature were 0.000654 mole, 441 °C and 83 °C, respectively.
