CATALYTIC BLOCK MATERIAL FOR OZONE DECOMPOSITION BASED ON CORDIERITE CERAMICS, METHOD FOR PURIFYING AIR FROM OZONE USING IT Russian patent published in 2024 - IPC B01D53/66 B01D53/86 B01J23/889 B01J23/72 B01J23/755 B01J35/04 B01J37/02 

FIELD: air transport.

SUBSTANCE: invention can be used to purify indoor air from ozone. The catalytic block material for ozone decomposition based on cordierite ceramics is characterized by the fact that the block weight is no more than 950 g. The content of the active composition based on transition metal oxides applied by impregnation is 9.3 wt.% at mass ratio: 5 parts manganese (IV) oxide, 3 parts copper (II) oxide and 2 parts nickel (II) oxide. A method for purifying air from ozone, according to which, through the specified catalytic block material at an absolute pressure of ~3.5 atm, a temperature of 160-250°C and a gas flow rate of 530-1000 kg/h, an air flow with an ozone concentration of 1.6±0.1 ppm is passed through.

EFFECT: increasing the efficiency of ozone decomposition and the strength of catalytic block material that does not contain noble metals.
