Activated carbon It is also called activated carbon black. It is black powder or granular amorphous carbon. The main components of activated carbon include oxygen, hydrogen and other elements besides carbon. Due to the irregular arrangement of microcrystalline carbon in structure and pores between cross connections, activated carbon will produce carbon tissue defects during activation, so it is a porous carbon with low stacking density and large specific surface area.

At present, activated carbon in the market mostly refers to coal based activated carbon. The production of coal based activated carbon mostly uses high-quality anthracite as raw material, and is made by advanced technology. The appearance of coal based activated carbon is black columnar particles. Coal based activated carbon has a long history of development in China's activated carbon industry. Coal based activated carbon entered China as early as the 1970s and 1980s. After more than 20 years of development, China has made remarkable progress in the technology of coal based activated carbon. At the same time, there are more types of activated carbon in the market, such as blocky activated carbon, round activated carbon, powdered activated carbon, irregular activated carbon. Of course, some activated carbon with different shapes use different materials.

Explain the adsorption principle of activated carbon. Activated carbon has reasonable pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration, and low cost, so it can be widely used in many industries, such as sewage treatment, waste gas treatment, purification of industrial and living water, solvent recovery, etc, Therefore, the development prospect of activated carbon is considerable and indispensable.
