Abstract:

The catalytic oxidation of NO to NO2 in flue gas will enable removal of NOx through wet scrubbing of NOx simultaneously with SO2.The activity of catalyst used in reaction has strong relation with its support material. In this work the oxidation of NO to NO2 in the simulated flue gas (NO 550ppm, SO2 2500ppm, O2 4.5% and balance N2) has been investigated over different oxide support materials. The tests of support activities were carried out in a fixed-bed reactor at a space velocity of at least 3000h-1. The effluent gas composition was analyzed by gas chromatography. The SO2 effect on the oxidation pf NO at 150℃ was studied using four different support materials as Al2O3, TiO2, ZrO2 and SiO2.
