METHOD OF OBTAINING PRODUCT FOR AIR REGENERATION Russian patent published in 2014 - IPC A62B11/00 A62D9/00 B01D53/62 

FIELD: chemistry.

SUBSTANCE: method of obtaining product for air regeneration consists in interaction of hydrogen peroxide solution, stabilised with magnesium sulfate, and lithium and potassium hydroxides with further dehydration of obtained alkaline solution of hydrogen peroxide by its spraying in flow of drying agent. Halogenides of alkali metals are introduced into hydrogen peroxide solution after its mixing with magnesium sulfate and lithium hydroxide before addition of potassium hydroxide with molar ratio potassium hydroxide/alkali metal halogenide, equal 15÷105. Chlorides of lithium, sodium, potassium or their mixture are used as alkali metal halogenide.

EFFECT: product for air regeneration, obtained in accordance with invention, has higher dynamic capacity by carbon dioxide per weight unit and provides longer time of protective action when exploited in systems of human life support.
