METHOD OF DECONTAMINATING SPENT ACTIVATED CARBON TO OBTAIN CALORIFIC FUEL Russian patent published in 2012 - IPC C01B31/08 C10J3/46 C01B3/02 B01J20/34 

FIELD: chemistry.

SUBSTANCE: invention relates to decontamination of wastes. Spent activated carbon undergoes thermal treatment with water vapour. The water vapour is split into two streams, part of which is fed into a plasmatron. The low-temperature vapour plasma obtained in the plasmatron is fed into a container where, upon mixture with the remaining part of the water vapour, a high-temperature jet of reaction gas at temperature 1000-1200°C is obtained. The activated carbon is blown with the obtained reaction gas. 1.3-1.5 kg of water vapour is spent on 1 kg of activated carbon. A gaseous mixture containing H₂ and CO is obtained from decontamination of the spent carbon.

EFFECT: possibility of obtaining a valuable product in form of a gaseous mixture containing H₂ and CO during decontamination of spent activated carbon.
