What is Activated Carbon?
Activated carbon is a carbon-based material that has been processed to maximise its adsorptive properties, yielding a superior adsorbent material. Activated carbon boasts an impressive pore structure that causes it to have a very high surface area on which to capture and hold materials, and can be produced from a number of carbon-rich organic materials, including:
- Coconut Shells
- And more…
Types of Activated Carbon
Powdered Activated Carbon (PAC)
Granular Activated Carbon (GAC)
Granular activated carbons generally range in particle sizes of 0.2 mm to 5 mm and can be used in both gas and liquid phase applications. GACs are popular because they offer clean handling and tend to last longer than PACs.
Extruded Activated Carbon (EAC)
Properties of Activated Carbon
While apparent density will not effect the adsorption per unit weight, it will effect the adsorption per unit volume
The ash content of activated carbon is a measure of the inert, amorphous, inorganic, and unusable part of the material. The ash content will ideally be as low as possible, as the quality of the activated carbon increases as ash content decreases.
