Technical Document

Brief Overview

Activated carbon, also known as activated charcoal or activated coal, is a form of carbon distinguished by its tiny pores that significantly increase its surface area. This expanded surface area is crucial for adsorption, a process where particles like atoms, ions, or molecules in gas, liquid, or solid form are attracted and held onto the surface. Activated carbon's ability to trap these particles within its internal pore structure through electrostatic attraction or chemisorption makes it valuable across industries. It plays a vital role in removing harmful substances in chemical processes, accelerating chemical reactions, and acting as a carrier for biomass and chemicals.

Manufacturing Process

Activated carbon typically originates from coconut shell charcoal or coal. To produce activated carbon, the material undergoes a controlled burning procedure in a sealed environment, specifically designed for the pyrolysis process.

This transformation primarily aims to open the pores of the carbon charcoal. Initially, the charcoal possesses an area of 2 m2/g, but through this process, it expands to a range of 300-2000 m2/g, becoming activated charcoal. Activation occurs through two methods: a mild oxidation reaction using water vapor at temperatures ranging between 900-1000°C or dehydration facilitated by chemicals or salts.

Water Treatment Industry

Currently, activated carbon is widely used in water treatment, including the restoration of groundwater and the treatment of service water. It's commonly used in either powder or granular forms, chosen according to specific application needs and process intricacies.
