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.

The National Space Development Agency of Japan (NASDA) is constructing the Isolation Chamber in Tsukuba Space Center (TKSC) by March 1996. The Isolation Chamber will be used to basic training for Japanese astronauts, development for crew training technology and research for manned space technology. This paper describes the outline of the Isolation Chamber.

In the closed environments, removal of trace contaminants generated from persons, animals, and plants is important function to keep the environment below the allowable level. We conducted the fundamental tests in order to confirm design of TCCA (Trace Contaminants Control Assembly) for Closed Ecology Experiment Facilities (CEEF), and obtained the following results; 1) The palladium-on-alumina catalyst is suitable for CO, CH4, C2H4 conversion at temperature lower than 400°C. 2) The alkali impregnated AC (activated charcoal) is effective for NO2, SO2 removal and prevents catalyst poisoning from SO2. 3) The active-desorbing conducted by hot air blow-throw an AC is effective for C2H5OH, CH2Cl2 desorbing. We discuss the fundamental test and design conditions for TCCA.
