Coal based granular activated carbon

Product Introduction
Coal based granular activated carbon is made from high quality Datong coal, which is crushed into 2-8mm,after carbonized and activated, then recrushed and sieved into qualified production. That coal based granular activated carbon bear fully developed porous structure, large specific surface area (especially large micropore volume), and great hardness, which leads to an extremely adsorption ability to organic substances and free chlorine in water and harmful components in air as well. As a result, coal based granular activated carbons are suitable adsorption of deep purification of drinking water, industrial water, waste water and separation of gaseous. It also widely used in discoloration and deodorization of refining sugar, monosodium, pharmacy, wine, drink.Generally used in organic solvent recovery and refining precious metal.
Technological process


Selected high-quality bituminous coal from Datong is used as raw material, directly crushed and sieved into 2-8 millimeter particle sizes. Activated raw materials are obtained through carbonization and activation, and then crushed and sieved into qualified crushed activated carbon according to customer requirements.
