Development of CO
Remover for Aircraft Advanced ECS
The Carbon Dioxide (CO2) remover of the next generation that composes Aircraft Advanced Environmental Control System (ECS) is developed. The trial manufacture of adsorption element made of Metal Foil and adsorption module body were conducted. And the CO2 adsorption/desorption ability was examined. The micro porous was formed on the surface of the metal foil by the anodic oxidation method, and amine system organic compound was supported in the porous to add the selective adsorption function for low concentration of CO2. The CO2 adsorptive separation performance was 0.2×10−3kg/m2 by the thermogravimetry examination result. In performance test with adsorption module, it was demonstrated to be able to purify the CO2 concentration to 0.04vol% or less in cabin air by the adsorption/regeneration examination that assumed the entrance CO2 concentration 0.2vol% and the 6 minutes cycle. In addition, the basic design of CO2 Remover Unit was done intended for 53 passengers civil aircraft, and the dynamic performance was estimated by the numerical computation.
