FIELD: process engineering.
SUBSTANCE: invention may be used in chemical, petrochemical and pulp-and-paper industries. Catalyst is fed into catalytic reactor from bin 13 by ejector 14 via loading branch pipe 7. Air is forced for layer fluidisation via branch pipe 3 under gas-distribution grating 8. Catalyst layer is heated to 300-400 °C. Then, coal is fed into layer via branch pipe 4. Layer temperature is increased to 500-750 °C by fuel combustion heat. Humid sediment is fed into layer via branch pipe 15. Solids of thermal oxidation are cooled down, separated from flue gases and treated by water solution of inorganic acid.
EFFECT: higher efficiency of treatment.
