Detailed Classification and Selection Guide of Activated Carbon

Temmuz 5, 2024

There are thousands of activated carbon models in the world, how to differentiate between them? This article classifies activated carbon in detail to help you choose the right activated carbon more quickly and accurately. Activated carbon can be categorised according to its raw materials, forms and uses. Here are some common types of activated carbon:

Coal-based activated carbon

Made from coal as raw material, coal raw material can be divided into bituminous coal and anthracite. The places of origin include Xinjiang, Shanxi and Ningxia in China. Coal from different origins has different advantages, and the indexes of the activated carbon produced are also different. Huamei Activated Carbon can blend raw materials from different origins according to the specific needs of customers to produce activated carbon that meets the requirements.

A: Coal based granular activated carbon

Direct coal based granular Activated Carbon: Due to the different origins of coal, the indexes of activated carbon produced are also different. For example, activated carbon produced with Shanxi coal has high strength but also high ash content; activated carbon produced with Xinjiang coal has low ash content but low strength. HUAMEI Activated Carbon blends raw materials according to customer requirements to produce granular activated carbon with low ash and high strength, which is suitable for water treatment, air treatment and other liquid phase treatment.
Agglomerated Activated Carbon: Adopting Calgon's production technology, we produce agglomerated activated carbon with high molasses value, which is suitable for food and beverage decolourisation.
Column Crushed Granular Activated Carbon: The original column carbon is crushed and sieved into granular activated carbon of specified size. It is characterised by high CTC and high butane adsorption value, and is suitable for special fields such as automobile carbon canisters.

B: Coal based column/pellet activated carbon

Anthracite columnar/pellet activated carbon: Ningxia anthracite is the best raw material for producing columnar activated carbon, which produces activated carbon with high strength, low ash content, high CTC, high bulk density, and the best effect in gas phase adsorption.
Bituminous coal columnar activated carbon: activated carbon produced by bituminous coal has medium and large pores, slightly lower strength, slightly higher ash, lighter bulk density, but the molasses value and methylene blue value are higher, and the decolourisation effect is remarkable.

C: Coal powder activated carbon:

After carbonazition and activation of raw coal, grinding powder to 200 mesh or 325 mesh, suitable for sewage treatment and waste incineration field.

Hindistan cevizi kabuğu aktif karbon

Made from coconut shell, coconut shell is mainly from Hainan, China, Indonesia and Davao, Philippines. Coconut shell production in Hainan, Huamei Activated Carbon imports coconut shell carbonised material from Indonesia and the Philippines in order to produce high quality coconut shell activated carbon.

Hindistan cevizi kabuğu granül aktif karbon: with a strength of up to 99% and ash content as low as 2%, it is mainly used in gold refining and drinking water industry.
Coconut shell columnar activated carbon: CTC80-100, strength 98%, ash content below 8%, mainly used in solvent recovery field.
Coconut shell powdered activated carbon: mainly used in food addition and other fields.

Wood-based activated carbon

Wood powdered activated carbon: wood chips as raw material, powdered activated carbon produced by phosphoric acid method, mainly used for food and beverage decolourisation.
Wooden columnar activated carbon: used for solvent recovery and gas treatment.

Depth processing activated carbon

Silver-impregnated carbon: It is mainly used to carry 0.1-0.3% silver in coconut shell granular carbon, and is mainly used to improve the taste of drinking water.
Acid washing carbon: mainly used to reduce the ash content of activated carbon and improve its purity.
Impregnated carbon: for example, impregnated with potassium hydroxide, impregnated with phosphoric acid, impregnated with PTFE and other agents, in order to improve the adsorption capacity of a certain gas.
Sulphur-carrying carbon: mainly used to remove mercury vapour.
These categorisations help to choose the right activated carbon for specific needs to achieve the best use. If you have specific needs or questions about a particular type of activated carbon, please feel free to inquire further.
