Coconut Shell based Activated Carbon

Manufacturing Process of Coconut Shell Charcoal

Operations overview of Coconut Shell Charcoal

  • Raw Coconut shell moved into Shell dryer.
  • By using this dryer, the coconut shell moisture level is reduced up to below 10%
  • Then Dried coconut shell moved into Carbonization kiln.
  •  In the carbonization kiln the coconut shell will be burned up to 700-800 Degree C temperature by controlling the air into the high-pressure blower. Approximately after 3 hrs the coconut shell will be converted into Charcoal, then it will be moved to coolant for cooling and get output of good quality charcoal.
  • During carbonization process, generating flue gases will be moved through Incinerator for burning at 1200 Deg C temperature. In this stage the flue gases will be completely burned and still available small amount of flue gases at very high temperature passes through   heat exchanger and flue gas temperature getting down then these flow gases pass through Wet scrubber (Pollution control equipment).
  • These wet scrubber systems are a diverse group of air pollution control devices that can be used to remove some particulates or gases  from industrial exhaust streams. Contaminated air from Source point drawn through the inlet by the Blower. In the Scrubbing Process.
  • Polluted Air is mixed with the water and considerable number of harmful substances is removed from air.
  • These wet scrubbers are working with three stages such as Water spraying, Smoke filtering & Sludge tank.
  •  Finally, the outlet of suspended particulate matter (SPM) through chimney will be below 150mg/Nm3 as per pollution control board norms.

Benefits of Coconut Shell Charcoal (to Activated Carbon conversion)


It has more micro-pores than even coal based activated carbon making it ideal for adsorption of volatile organic chemicals during filtration.

No taste

Leaves no taste or odors.

Renewal source of feedstock

Coconuts are readily available in India for the feedstock.

Long lasting

Micro-pores give it a strong mechanical strength thereby being more resistant to wear and tear.

Spent AC can be recycled

Following reactivation process AC can be reused.
