Activated carbon

What is Activated Carbon?

Activated carbon is a kind of microcrystalline carbon material with black appearance, developed internal pore structure, large specific surface area and strong adsorption capacity, which is a kind of commonly used adsorbent, catalyst or catalyst carrier.Activated carbon is widely used in almost all sectors of the national economy and People's Daily life, such as water purification, gold extraction, sugar decolorization, drug injection refining, blood purification, air purification, human safety protection.

Classification of activated carbon by material

Coconut shell activated carbon

Coconut shell activated carbon with high-quality nut shell or coconut shell as raw materials,It is a kind of activated carbon which is refined by the processes of carbonization, activation, superheated steam catalysis and so on. It has the advantages of good wear-resisting strength, developed voids, high adsorption performance, high strength, easy regeneration, economy and durability, etc. Mainly used for drinking water, purified water, wine, beverage, industrial sewage purification, decolorization, dechlorination, deodorization, desiccant, gold refining, catalytic carrier and other aspects.

Coal based activated carbon

Coal based activated carbon is produced through a series of processes, including carbonization, cooling, activation, washing, etc，it has the advantages of high strength, developed pores, large specific surface area and especially large volume of micropores.

According to the use can be divided into water purification, air purification, decolorization, solvent recovery, injection, protection and other purpose.Due to the acid-resistant, alkali-resistant and heat-resistant performance of coal based activated carbon, and the fact that granular activated carbon can be easily regenerated after adsorption saturation, it is an essential activated carbon adsorption material in modern industrial production and environmental protection.

Activated carbon application

Activated carbon for petroleum refineries:
Gasoline desulfurization carrier activated carbon, as the catalyst carrier, it is widely used in the petrochemical industry for high-purity gas and liquid adsorption, desulfurization, deodorization and so on;

Activated carbon in water treatment:
Water purification activated carbon, it is used for water purification, drinking water deodorization, dechlorination; high-end water treatment in boiler water, food, beverage industries, etc.;

Activated carbon for gold recovery:
It is used for the separation and extraction of non-ferrous metals, especially used in heap leaching method to extract gold and tail liquid recovery;

Food grade activated carbon:
Refining and decolorizing in beverages, alcohol, MSG mother liquor industries and so on.

Activated carbon for edible oil purification:
Untreated edible oil contains natural toxins or pollutants, such as polycyclic aromatic hydrocarbons (PAH), which are hydrocarbons with two or more benzene rings, and are an important environmental and food pollutant.
After testing, Zhulin wood powder carbon can effectively remove these pollutants, with a removal rate of 98%.

FAQ about activated carbon

• what is wash regeneration activated carbon?
This type of activated carbon is mainly used for H2S removal, which is also called catalytic carbons. It will convert adsorbed H2S into sulfuric acid and sulfurous acid, which is stored more efficiently on carbon than is H2S (but not as efficiently as elemental sulfur), and only can be regenerated by simply washing it with water. it is a unique product that is manufactured without the use of chemical impregnation to the surface of the carbon.
• What is the phenol adsorption value of 1000mg/g coal granular activated carbon?
Depending on the different process and coal raw material, it is generally 180-200mg/g.
