Experimental study of catalytic removal of ozone in an aircraft cabin

In order to remove ozone from the bleed air in aircraft cabins by catalysis method, two different catalysts (nanometer TiO₂ and MnO₂-CuO) were chosen to analyze the ozone removal efficiency. A plasma ozone generator was used to control the ozone concentration in a reactor. The effects of flow velocity, initial concentration, and humidity on the ozone removal were analyzed. The results show that the MnO₂-CuO catalyst was more effective in ozone degradation. The results in this paper can be a foundation for further research on catalytic removal of ozone for bleed air purification in an aircraft cabin in the future.
