摘要

The article presents a possible design of an atmosphere revitalization system (ARS) as a component part of a new generation life support system (LSS). The main goal of the test investigation was to block formation of solid hard-to-remove carbon as a by-product of carbon dioxide and hydrogen processing. The Bosch reaction stage of CO2 conversion into CO and water was chosen as the core one. Beside the C02 and hydrogen conversion unit, other ARS constituents are a palladium membrane to generate ultrapure hydrogen, a water electrolysis unit, a hydrogen accumulator and a hydrogen absorber. To reach the materials balance, ARS was complemented with a system for trace contaminants and CO2 removal, and a Co2 concentrator. Zeolites in the CO2 removal system and concentrator ensure microwave energy absorption. Hydrogen is accumulated and absorbed by a LaNi5-based intermetallide. The palladium membrane serves to separate hydrogen from the CO-CO2 mixture.
