High quality Coal Based Powder Activated Carbon

Granular Activated Carbon(GAC).

GAC are irregular shaped particles formed by broken and sieving. These products range from the sizes 0.2mm to 5 mm. They have the advantages of being harder and longer lasting than powdered activated carbons, clean to handle, purify large volumes of gas or liquids of a consistent quality, and can be reactivated and reused many times. GAC are used in both liquid and gas phase applications and in both fixed and moving systems.

Columnar(PELLET OR Extruded ) Activated Carbon.

These are cylindrical pellets with diameter ranging from 1mm to 9mm. The extrusion process, together with the raw material used, ensures that the end product is hard and suitable for heavy duty applications. The extruded pellet form gives a low system pressure drop, which is an important consideration in the gas-phase uses. Markets lie in solvent recovery, gas purification and automotive emission control, where the high volume activity, low pressure drop and high stock resistance of extruded carbon enable them to last the entire life of the vehicle.

Powder Activated Carbon(PAC).

PACs generally have a particle size distribution ranging from 0.045mm to 0.2mm, coarser and finer grades are all available. Advantages of powdered activated carbons are their lower processing costs and their flexibility in operation. The dosage of powdered activated carbon can be easily increased or decreased as process conditions vary. PACs are mainly used for liquid-phase adsorption. They are added to the liquid to be treated, mixed with the liquid and, after adsorption, are removed by sedimentation and filtration.
