Activated carbon is a commonly used non-polar adsorbent with stable performance and corrosion resistance, so it is widely used. It is a general term for carbon-based substances with adsorption properties. The carbon-containing organic matter is heated and carbonized to remove all volatile matter, and then activated by chemicals (such as ZnCl2, etc.) or water vapor to form a porous carbon structure adsorbent. There are two types of activated carbon: powdered and granular. Granular activated carbon is mostly used in industry.
Due to different raw materials and preparation methods, the pore size distribution is different, which is generally divided into: carbon molecular sieve, with a pore size below 10×10-10m; activated coke, with a pore size below 20×10-10m; activated carbon, with a pore size below 50×10-10m .
