What is activated carbon?


Activated carbon is one of the most popular and most commonly used non-polar adsorbents in recent decades. Activated carbon has stable performance, anti-corrosion, and is also a renewable purification material, so it is widely used. The main materials are high-quality anthracite, high-quality coconut shell, nut shell, etc. as raw materials, which are produced through high temperature carbonization at 600-800 degrees, activation, crushing, screening and other production processes.

Activated carbon is a general term for carbon-based substances with adsorption properties. The carbon-containing organic substances are heated and carbonized to remove all volatiles, and then activated by drugs (such as ZnCl2, etc.) or water vapor to make porous carbon structure adsorbents.

What is the major quality index for activated carbon?

At present, the most common activated carbons on the market are: coal granular activated carbon, coal powder activated carbon, pellet activated carbon, coconut shell activated charcoal, fruit shell activated carbon, etc. The most important indicators of activated carbon are: iodine value, PH value, specific gravity, specific surface area , ash, moisture, etc., are all important indicators to measure the quality of activated carbon.

What are the functions and uses of active carbon?

As a special carbonaceous material, activated carbon is widely used in industry, agriculture, military protection and people's daily life due to its developed pore structure, huge specific surface area, good stability, strong adsorption capacity and excellent regeneration ability. Many fields of life are widely used in decolorization and purification, water treatment, deep purification of drinking water, gas separation and purification, air purification, removal of toxic and harmful gases, catalysts and catalyst carriers.
