NO oxidation using O3 is studied, including the product composition under different conditions and selectivity in complex flue gas. The O3/NO molar ratio determines type of products. N2O5 generated when greater than 1, yield increases with improvement ratio. High temperature leads to decomposition NO3 decrease yield. When caused high-temperature region, increase residence time not beneficial generation N2O5. In addition, water vapor gas formation at low temperatures (60–90 °C), but SO2, CO, HCl show little influence on selectivity.
