Abstract

Kinetics of carbon dioxide chemisorption and oxygen release under the natural convection kinetics at temperatures of 20 and 5°C by nanocrystalline KO2 deposited on a fiber-glass matrix was studied. The processes of oxygen release and carbon dioxide absorption are well described by the contracting-sphere equation. The reaction rate constants were calculated and the activation energy of the processes was estimated. To verify the suggested physical model, the concentrations of carbon dioxide and oxygen were calculated at other process parameters. It was demonstrated that nanocrystalline KO2 on a fiber-glass matrix can be effectively used to create local atmospheres in life-support systems.
