Classification of AC materials.

Criteria	Particle size	Properties	Applications	References
Powdered AC	<1.0 mm; Diameter: 0.15–0.25 mm	Higher surface area, extraordinary volume per gram, and greater purity	As an additive in vessel, waste water treatment, classifiers, and gravity filter	[50]
Granule AC	0.42 to 0.84 mm	Suitable for many organic chemicals, able to improve taste/odor, and removes chlorine	Vapor and liquid adsorption, water treatment, deodorization, separation of components	[51]
Extruded AC	0.8 to 130 mm	Low pressure drop, high mechanical strength, and low dust content	Gas phase applications	[52]
Beads AC	0.35 to 0.8 mm	Low pressure drop, high mechanical strength, and low dust content	Adsorbent for waste water	[53]
Impregnated AC	0.8 to 200 mm	Porous carbon impregnated with inorganic materials (iodine, silver, cations) and; antimicrobial; antiseptic	Pollution control and; purification of domestic water	[54, 55]
