Classification and analysis of activated carbon

- Mar 18, 2019-

Activated carbon is a porous carbon-containing substance with a highly developed pore structure, which provides a large number of surface area, which can be fully exposed to gases or impurities, giving it a unique and powerful adsorption as an excellent adsorbent, catalyst or catalyst carrier, activated carbon is now active in petrochemical, electricity, air purification, sewage treatment, food, pharmaceuticals, beverages and many other fields. Today, the little editor brought everyone here. Learn about the points of activated carbon Class.


Activated carbon According to the shape is generally divided into powdery activated carbon, granular activated carbon, unshaped material activated carbon, cylindrical Activated carbon, spherical activated carbon, other shape activity Carbon.

activity Carbon


According to the classification of raw materials, mainly divided into: Wood activated carbon, coal activated carbon, shell activated carbon, coconut shell activated carbon, etc., Here's a highlight of this section.

Wooden Activated Carbon
Raw materials and processing technology: Wood activated carbon is based on wood, sawdust as raw materials, by high temperature carbonization, activation and Refined from a variety of processes
Main features: With large specific surface area, high activity, developed microporous, strong decolorization force, large pore structure and other characteristics. Large pore structure, can have more than the color of the adsorption liquid, such as a large variety of substances, impurities.
Applications: Mainly used in food, alcohol, oil, beverages, dyes, chemicals, tap water purification, sewage treatment, cod reduction, medicinal activated carbon and other uses of decolorization.

Coal Activated carbon
Raw materials and processing technology: Coal activated carbon to high-quality anthracite as raw materials, after carbonization → cooling → activation→ Washing and a series of processes developed.
Main features: the appearance is generally black cylindrical activated carbon, amorphous coal granular activated carbon, also known as broken Shredded charcoal. The pore structure is developed, and the pore size lies between the coconut shell activated carbon and the woody activated carbon, which has adsorption It can be strong, high mechanical strength, easy to regenerate repeatedly, low cost and so on.
Applications: For the purification of toxic gases, waste gas treatment, industrial and domestic water purification treatment, solvents Recycling and other aspects.

Coal Activated carbon


Fruit Shell Activated Carbon
Raw materials and processing technology: fruit shell activated carbon mainly to walnut shell, apricot shell, peach shell, jujube shell and other shell as the original Material, through carbonization, activation, refining and processing.
Main features: With large surface area, high strength, uniform particle size, developed pore structure, strong adsorption performance and other characteristics. can effectively adsorb free chlorine, phenol, sulfur, oil, colloid, pesticide residues and other organic Pollution and recycling of organic solvents.
Applications: In pharmaceutical, petrochemical, sugar, beverage, alcohol purification industry, drinking water, industrial water and deep purification of wastewater are widely used.

Fruit Shell Activated Carbon


Coconut Shell Activated Carbon
Raw materials and processing technology: Coconut shell Activated carbon also belongs to the shell activated Carbon category, coconut shell as raw material, by After screening, water vapor carbonization refining treatment, and then by the removal of miscellaneous, activation screening and other series of processes made.
Main Features: Coconut shell activated carbon Its main characteristics are small density, light feel, the shape of amorphous particles, It has high mechanical strength, developed pore structure, large specific surface area, fast adsorption speed, high adsorption capacity and easy Regeneration, durability and other characteristics.
Applications: Mainly used in food, beverages, alcohol, air purification activated carbon and high-purity drinking water deodorization, Removal of heavy metals, chlorine removal and liquid decolorization in water. And can be widely used in the chemical industry solvent Recovery and gas division Away and so on In addition, recycled activated carbon, petroleum-activated carbon and Mineral raw materials such as activated carbon and other categories. Activated carbon also plays an important role in the water purification industry, the most commonly used is the fruit Shell activated carbon and coconut shell activated carbon
