(Summary description)Speaking of activated carbon, the first thing everyone thinks of is to remove formaldehyde and absorb odors, but many people don’t know what activated carbon is. Today I will briefly explain to you “what activated carbon is”! Whether in our lives or in industry, the scope of use of activated carbon is very wide. It is made from coal, wood, fruit shells and other raw materials through carbonization, activation and post-processing. Currently, there are four common shapes: shaped activated carbon, powdered activated carbon, activated carbon fiber and granular activated carbon. What is activated carbon Activated carbon is also called activated carbon black. It is black powdery or granular amorphous carbon. In addition to carbon, the main components of activated carbon also include oxygen, hydrogen and other elements. The structure of activated carbon is due to the irregular arrangement of microcrystalline carbon and pores between cross-connections. Carbon organization defects will occur during activation. Therefore, it is a porous carbon with low packing density and large specific surface area. Activated carbon is odorless, tasteless, sandless, insoluble in any solvent, has selective adsorption capacity for various gases, and has high-capacity adsorption capacity for organic pigments and nitrogen-containing alkali. The total surface area per g can reach 500~1000m2. Relative density is about 1.9~2.1, apparent relative density is about 0.08~0.45
