Made from different raw materials such as coconut shell, wood, and coal, Activated carbon is produced through high-temperature carbonization, activation, and refinement, resulting in different types of activated carbon.
In this article, you can learn about the differences among these three types of activated carbon in terms of production processes, pore distribution, applications, physical characteristics, and usage costs.
Wood Activated carbonis produced from selected wood materials using both physical and chemical methods to create activated carbon with advantages such as high porosity, large molecular adsorption capacity, high permeability, and purity.
Coal-basedActivated carbon is made from coal mines (such as bituminous coal, anthracite, and lignite) using chemical methods like steam activation. It features a developed pore structure, excellent adsorption performance, and high mechanical strength.
Coconut shell Activated carbonis mainly made of coconut shell, activated by steam and phosphoric acid. It has more micropores and a small amount of macropores, and has a good adsorption effect on volatile organic compounds.
Although the three types of activated carbon are all prepared by physical or chemical methods, their preparation methods are different due to different raw materials, which are mainly reflected in the following aspects:
Manufacturing
Coal-based activated carbon is mainly prepared by physical carbonization and chemical activation;
Wood-based activated carbon is mainly prepared by chemical methods such as steam activation and phosphoric acid activation;
Coconut shell activated carbon is mainly prepared by chemical methods such as steam activation.
Pore distribution
Coal-based Activated carbon has diverse pore distribution and rich micropores.
Bituminous coal activated carbon has a large micropore surface area, and the micropore volume and carbon content are between 70% and 90%, which is an ideal type of coal;
Lignite activated carbon has a larger pore size;
Wood-based activated carbon has rich mesopores and micropores, and has the advantages of high porosity, large molecular adsorption capacity, good permeability, and high purity.
Compared with other types of activated carbon, coconut shell activated carbon has a larger surface area, higher micropore density, larger pore volume, and more than 50% more micropores than coal-based activated carbon.
Coal-based activated carbon has a strong adsorption capacity for various organic matter in water, free chlorine, harmful gases in the air, etc. It is an excellent adsorbent for deep purification of urban drinking water and is widely used in sewage treatment, industrial air purification, water purifiers, food and beverage industry purification, medical and pharmaceutical industries, etc.
Wood activated carbon has a high adsorption rate and fast filtration speed. It is often used in food decolorization, water purification, air purification, solvent recovery, deodorization in the food and beverage industry, etc.
Coconut shell activated carbon has high hardness, low ash content, and high purity, and is more suitable for drinking water treatment and reverse osmosis water applications.
Appearance
Coal-based activated carbon is available in granular, pellet and powder forms.
Coconut shell activated carbon is mainly in granular form.
Wood activated carbon is mainly in powder form.
Coconut shell activated carbon, wood activated carbon, and coal-based activated carbon each have unique properties and applications. When choosing, you must balance specific requirements, environmental considerations, and sustainability factors.
Generally, coal-based activated carbon is best for odor removal, coconut shell activated carbon is best for dechlorination, and wood activated carbon is best for powder decolorization.
