Coconut Shell Activated Carbon Production Process Explained

Coconut shell activated carbon is widely used in water treatment, gold recovery, air purification and food processing. Here are the main production steps:

1. Raw Material Preparation

Select high-quality coconut shells, remove impurities such as coconut meat and dust, then crush and dry them to suitable particle size and low moisture content.

2. Carbonization

Heat crushed coconut shells in an oxygen‑limited environment to remove volatile components and form a preliminary carbon structure with basic adsorption ability.

3.Activation

Use high-temperature steam or other activators to etch the carbon material, developing rich micropores and greatly improving specific surface area and adsorption performance.

4. Washing & Purification

Wash the activated carbon to reduce ash content, remove soluble impurities and ensure product purity for industrial and food‑grade applications.

5.Drying & Grading

Dry the cleaned activated carbon to control moisture, then screen it into standard particle sizes according to different usage requirements.

6.Quality Inspection & Packaging

Test key indexes including iodine value, hardness and ash content. Qualified products are packaged and stored for delivery.
