THERMALLY ACTIVATED STABLE TO SELF-IGNITION COAL Russian patent published in 2014 - IPC C01B31/08 B01D53/02 B01D53/81 B01J20/20

Abstract RU 2535684 C2

FIELD: chemistry.

SUBSTANCE: thermal stability of thermally activated cellulose-based coal is increased by influencing it with halogen and/or a halogen-containing substance, containing bromine, chlorine, fluoride, iodine, ammonium bromide, other nitrogen-containing salts of halogens or calcium bromide. The said thermally activated coal contains approximately from 5 to 20 wt % of halogen relative to the total weight of the thermally activated coal, subjected to the impact of halogen and/or the halogen-containing substance. Such a processed cellulose-based coal is suitable for application in processes of reducing the content of harmful substances in flue gases, in particular in flue gases, the temperature of which is in the range approximately from 100°C to 420°C.

EFFECT: increased stability.
