A PROCESS FOR THE MANUFACTURE OF ACTIVE CARBON FROM COKE BREEZE, USEFUL FOR REMOVAL OF TOXICANTS FROM EFFLUENT WATER OF COKE PLANTS.

摘要

This invention describes a process for the manufacture of active carbon from coke breeze, a waste material, in a fluid bed reactor, pre-heated to 600 degree Celsius, allowing the temperature of the reactor, containing crushed and screened coke breeze, to rise steadily to 900 degree Celsius, injecting superheated steam from below the reactor, allowing the carbon materials to remain in a fluidised state for a time period in the range of 1 to 2 hours. After the activation period is over, the reactor is allowed to cool down to 350 degree Celsius. The product is discharged after adjusting the pH between 6.5 to 7.0. The active carbon so obtained is useful for removing toxicants from effluent water from coke plants.
