METHOD OF PRODUCING ACTIVE COAL Russian patent published in 2004 - IPC

Abstract RU 2233240 C1

FIELD: purification of liquids and gases.

SUBSTANCE: method includes grinding coal raw, its mixing with a binder, formation of granules, their drying up to 80-100^oC with a heating rate of 2-6^oC/min, carbonization produced by counterflowing of the granules and furnace gases at 350-540^oC, cooling of the carbonized granules in absence of air to a temperature of 40-70^oC, their thermal treatment up to a temperature of 800-870^oC and further activation by water vapor at a temperature of 900-950^oC.

EFFECT: enhanced efficiency.
