摘要

Procedure for the regenaracion spent Activated Carbon impregnated with caustic. The spent carbon is washed with water at a temperature of 22 to 76.7 025 C. Coal spent Wash is treated with a solution of Sodium hydroxide or Potassium Hydroxide, the 30 - 50%, to a temperature of 22 to 82.2 025 C and for a contact time of 13 to 24 hours to remove contaminants or Rganicos.The spent carbon of the previous stage is treated with a solution of caustic soda, 5 - 25%, to a temperature of 22 to 82.2 025 C and for a contact time of 3 to 24 hours, to remove Sulfur pollutants. Reducing the Moisture content of Coal to less than 18% by weight. Coal is used as Absorbent of organic compounds and sulphur odorous.
