Types of Activated Carbon

Powdered Activated Carbon (PAC)

Powdered activated carbons generally fall in the particle size range of 5 to 150 Å, with some outlying sizes available. PAC’s are typically used in liquid-phase adsorption applications and offer reduced processing costs and flexibility in operation.³

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.

Additionally, they offer improved strength (hardness) and can be regenerated and reused.³

Extruded Activated Carbon (EAC)

Extruded activated carbons are a cylindrical pellet product ranging in size from 1 mm to 5 mm. Typically used in gas phase reactions, EACs are a heavy-duty activated carbon as a result of the extrusion process.
