Activated carbon can be divided into coal-based activated carbon and coconut shell activated carbon according to material classification. As a professional activated carbon buyer, you may be very familiar with the difference between different materials of activated carbon, but for a new buyer of activated carbon, you may be more confused. When purchasing activated carbon, what material of activated carbon should I choose in the end?
Next, I will briefly introduce the difference between the two:

Coconut base activated carbon
1. High mechanical strength, unbreakable, long service life.
2. Low ash content (impurities), usually at 3%.
3. Microporous developed, pore size distribution is finer and pore space is denser.
4. Higher specific surface area (typically 1000-1800 m²/g).
1. More suitable for the adsorption of small molecules, such as volatile organic compounds (VOCs) or dissolved pollutants in water.
2. Stronger adsorption capacity for small molecule organic pollutants (e.g. benzene, trichloromethane) and heavy metal ions.
3. Superior performance in drinking water purification, air purification, gold extraction, etc.
1. Higher price, suitable for high requirements or fine processing (e.g. drinking water, pharmaceutical manufacturing).
2. Cost performance is more prominent in high-precision applications.
Coal base activated carbon
1. Lower mechanical strength, easy to break, the service life is shorter, but the price is lower.
2. Higher ash content ( impurities), usually at 12%.
3. The pore structure is dominated by mesopores and macropores, with relatively few micropores.
4. Relatively low specific surface area (generally 500-1200 m²/g).
1. Suitable for adsorption of large molecules adsorption.
2. Commonly used in industrial wastewater treatment and flue gas desulphurisation and denitrification.
3. Adsorbent in chemical production
1. Lower cost, suitable for large-scale applications (e.g. industrial wastewater treatment).
2. Economic options.
To sum up, the choice of what material of activated carbon is still based on the actual application, different materials and different processes have a very big impact on the void structure of the activated carbon, if the adsorbed material is a large molecule, such as pigment contaminated sewage, we have to choose the activated carbon with more developed macroporous, if the adsorbed material is a small molecule such as benzene, toluene, xylene, etc., we have to choose the activated carbon with well-developed microporous, the activated carbon is not the more expensive the better, nor can we blindly choose the right price activated carbon to give the maximum effect. Activated carbon is not the more expensive the better, also can not blindly choose the low price of activated carbon, choose the right activated carbon in order to play the maximum effect.
Huamei activated carbon has been in the activated carbon industry for more than 20 years, and our products have been sold in more than 30 countries, helping more than 200 customers to provide professional activated carbon purchasing guide.
