Activated carbon pellets also called carbon pellet or extruded activated carbon uses high-quality coal as raw material.
Activated carbon pellets are developed through a series of processes such as carbonization → cooling → activation → washing.
Its appearance is generally black cylindrical coal-based columnar activated carbon, and amorphous coal-based granular coal-based columnar activated carbon, also known as broken carbon.
Cylindrical coal-based columnar activated carbon, also known as columnar carbon, is generally made of powdered raw materials and binders through kneading and extrusion.
Compression molding is then made by carbonization, activation and other processes.
It can also be extruded with powdered coal columnar activated carbon and binder. It has the characteristics of developed pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration, and low cost;
It is used for purification of toxic gases, waste gas treatment, purification of industrial and domestic water, solvent recovery, etc.
Pellet activated carbon is a porous carbonaceous material. Its highly developed pore structure makes it have a huge surface area, so it is easy to fully contact with toxic and harmful gases (harmful impurities) in the air. This highly developed pore structure Structure - Capillaries form a strong adsorption force field. Thus, the unique adsorption performance of coal-based columnar activated carbon is given. When these toxic and harmful gases (impurities) hit the capillary, the strong adsorption force field around the pores of the coal columnar activated carbon will immediately suck the toxic and harmful gas (impurities) molecules into the pores to achieve the effect of purifying the air. But not all coal-based columnar activated carbons can adsorb harmful gases, only when the pore structure of coal-based columnar activated carbons is slightly larger than the diameter of harmful gas molecules, allowing harmful gas molecules to enter completely (not too large or too small) , in order to achieve the best adsorption effect.
