Abstract

Powdered activated carbon exhausted during glycerine bleaching can be regenerated and reused again. Glycerine retained by the exhausted carbon con be recovered before the regeneration process. Optimum glycerine recovery conditions were found to mix, efficiently, 4 parts (by weight) of wash water per part of exhausted carbon for half an hour a 80-85oC. About 36%, by weight from exhausted carbon was recovered as by this technique. Above 85% of the activity of the exhausted powdered activated carbon can be restored by thermal regeneration. Best results were obtained on the exhausted powdered activated carbon for an hour at a temperature of 500°C or higher.
