Ozone in aircraft cabin can bring obvious adverse impact on indoor air quality and occupant health. The objective of this study is to experimentally explore the ozone removal performance of flat-type catalyst film by loading nanometer palladium on the activated carbon fibers (Pd/ACFs), and optimize the configuration of ozone converter to make it meet the design requirements. A one-through ozone removal unit with three different Pd/ACFs space was used to test the ozone removal performance and the flow resistance characteristic under various temperature and flow velocity. The results show that the ozone removal rate of the ozone removal unit with the Pd/ACFs space of ۱.۵ mm can reach ۹۹% and the maximum pressure drop is only ۱.۹ kPa at the reaction temperature of ۲۰۰℃. The relationship between pressure drop and flow velocity in the ozone removal unit has a good fit to the Darcy-Forchheimer model. An ozone converter with flat-type reactor was designed and processed based on the one-through ozone removal experiment, its ozone removal rate and maximum pressure drop were ۹۷% and ۷.۵۱ kPa, separately, with the condition of ۱۵۰℃ and ۱۰.۶۳ m/s. It can meet the design requirements of ozone converter for air purification and develop a healthier aircraft cabin environment.Ozone in aircraft cabin can bring obvious adverse impact on indoor air quality and occupant health.
