Granular activated carbon in short GAC are irregular shaped particles formed by milling and sieving. These products range from the sizes 8---80/mesh, in industry feild 8---30/mesh is the most commonly used.
Activated carbon uses high-quality anthracite coal as raw material, and is developed through a series of processes such as carbonization, cooling, activation, and washing. Activated carbon appearance is divided into black cylindrical shape according to the shape of coal based columnar activated carbon; amorphous coal-based granular activated carbon, also known as coal-based broken activated carbon; black fine powder called coal powdered activated carbon. Coal based GAC activated carbon use high quality Antrracite as raw material , coal-based GAC activated carbon, also known as coal-based broken activated carbon, it's more cost efficitve use in dringking water and waste water treatment, and also can be used in sugar decoloration industry.
The first process includes dehydration and carbonization, heating the raw material, drying it at a temperature of 170 to 600°C, and carbonizing about 80% of the original organic matter.
The second process is to activate the carbon, which is accomplished by reacting with an activator such as water vapor and carbon. In the endothermic reaction, a mixed gas composed of CO and H2 is mainly produced, which is used to burn and heat the carbon to an appropriate temperature (800°C). to 1000 °C) to burn off all decomposable substances, resulting in a developed microporous structure and a huge specific surface area, so GAC anthracite coal granular activated carbon has a strong adsorption capacity.
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.In addition, granular activated carbons are nearly always regenerated and reused, The period between reactivation varies significantly but is on average 18 months. Loss of material during reactivation ranges from 5% to 15%.
