METHOD OF PRODUCING CERAMIC HIGHLY POROUS BLOCK-CELLULAR REGENERATIVE MATERIALS Russian patent published in 2022 - IPC C04B38/00 A62D9/00 

FIELD: technological processes.

SUBSTANCE: invention relates to chemical engineering of ceramic highly porous cellular materials and can be used for chemical regeneration of air in life support systems of manned aircraft and other closed objects of the Ministry of defense, EMERCOM of Russia and State Atomic Energy corporation "Rosatom". Method of producing ceramic highly porous block-cellular regenerative materials involves mixing a magnesium sulphate-stabilized hydrogen peroxide solution with sodium and potassium hydroxides with subsequent application of alkaline solution of hydrogen peroxide on porous matrix and dehydration of liquid phase on matrix, matrix used is ceramic highly porous block-cellular material based on electrocorundum and semi-porcelain foundry mass PFL-1, which is preliminarily held in an alkali solution with pH 12–13 for at least 1 hour and washed with distilled water to a neutral pH value.

EFFECT: development of a method of producing ceramic highly porous block-cellular regenerative materials, having high mechanical strength and degree of carbon dioxide mining during operation in life support systems of closed objects, improved environmental friendliness of the air regeneration process.
