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] |
