Application of Activated Carbon

Activated carbon filter foam is one of our major products.

Activated carbon plays an important role in the industrial field and in daily life. Activated carbon is an excellent carbon adsorbent with a large specific surface area, stable physical and chemical properties, and good selective adsorption properties.

What are differences between types of activated carbon? How are they classified?

1. Classified by raw materials:

CATEGORYRAW MATERIALS
Coal-based activated carbonLignite, peat, bituminous coal, anthracite and etc…
Wooden activated carbonSawdust, charcoal, coconut shell, walnut shell, apricot shell and etc…
Petroleum activated carbonAsphalt, petroleum coke
Regeneration carbonUsed charcoal

2. Classified by appearance:

CATEGORY CHARACTERISTIC
Powdered activated carbon(PAC)Powdery, mesh<80
Granular activated carbon(GAC)Granular, mesh>80
Spherical activated carbon(SAC)Ball shaped carbide being activated after carbonization, and raw material of a spherical resin also belongs to this class
Columnar activated carbon(CAC)Using coal, wood chips and etc as raw materials, the appearance is cylindrical
Fibrous activated carbon(FAC)Made of fibrous raw materials, diameter is 5-10μm. Generally felt, cloth, filament
Honeycomb activated carbon(HAC)Produce by extrusion process

3. Classified by different activation methods:

CATEGORYCHARACTERISTIC
Physical activated carbonProduced by using water vapor, CO2, flue gas, air as activator
Chemical activated carbonProduced by using chemicals such as zinc chloride, phosphoric acid, sodium hydroxide or potassium hydroxide as activators
Physical and Chemical activated carbonProduced by using chemicals and certain gases sequentially or simultaneously

We can produce activated carbon filter foam with different iodine value base on different types of the activated carbon as your requirement.
