Activated Carbon

About Activated Carbon

Activated carbon (also called activated charcoal) is a highly porous form of carbon used for purification, filtration, and adsorption. It is mainly composed of:

• Carbon: 8598% (the primary component)
• Oxygen: 110% (in surface functional groups)
• Hydrogen: 0.52%
• Nitrogen: 01%
• Sulfur: Trace amounts (depends on the raw material)
• Ash (mineral content): 115% (silica, calcium, iron, aluminium, magnesium, potassium, etc., depending on the source)

Common Raw Materials Used to Make Activated Carbon

• Coconut shells (highest hardness, widely used in water purification)
• Coal (bituminous, anthracite, lignite)
• Wood
• Peat
• Bamboo
• Agricultural waste (rice husk, nutshells, etc.)

Types of Activated Carbon

1. Powdered Activated Carbon (PAC) Fine powder, mainly used in water treatment.
2. Granular Activated Carbon (GAC) Granules used in water filters, gold recovery, and air purification.
3. Extruded/Pelletized Activated Carbon (EAC) Cylindrical pellets used in gas purification and industrial air treatment.
