Why are Coconut shells are preferred to produce activated carbon?
Thank to their high carbon content and hardness, coconut shells are an excellent raw material source to produce activated carbon. Activated carbons that are produced using coconut shells as the raw material are often sourced in geographic regions where coconuts are harvested, including India, Malaysia, Sri Lanka, the Philippines, and Viet Nam.
How is coconut activated carbon produced?
Coconut shells are first charred at the coconut grower or at a centralized facility designed to produce char. Activated carbon manufacturers then purchase the char and activate it at elevated temperatures and using steam in a kiln or furnace, similar to the process for coal-based activated carbons. The final product is screened to a variety of mesh sizes for both vapor phase and liquid phase applications.
