[Plasmo-catalytic removal of oxygen-containing organic compounds from the spacecraft air].

The process of removal of the vapors of oxygen-bearing harmful organic contaminants, i.e. acetone, ethanol, acetaldehyde, ethyl acetate from the air was studied. The treatment of contaminated air with a non-equilibrium discharge was shown to induce a series of sequentially parallel reactions purifying air by 30-85% and synthesizing ozone. The installation of an ozone-catalytic reactor next to plasmochemical would make possible air decontamination up to 93-95% at 60-65 degrees C and ambient pressure. The devised method of air revitalization offers some advantages over the standard system which utilizes the adsorption/catalytic principle, as it will not require regeneration of individual nodes.
