What is used for activated carbon?

What is the wood activated carbon?
Zhulin Carbon specializes in the production of various types of wood activated carbons. The wood activated carbon uses high-quality wood chips and fruit shells as raw materials, adopts advanced production technology, and is refined and processed through carbonization and activation.
The appearance is non-toxic, odorless and well-developed pores. It has the advantages of large specific surface area, strong adsorption capacity, fast filtration speed, and high decolorization purity.
Wood activated carbon is mainly used in decolorization, purification and refining in the chemical, textile, fuel, food, environmental protection, and pharmaceutical industries. It is widely used for hydroquinone, glycerin, electroplating, fluorescent whitening agent, edible oil, monosodium glutamate, citric acid, industrial sewage, tap water, purified water and other industries.
How about the quality of activated carbon powder?
In terms of quality, wood activated carbon is far better than common activated carbon. Wood activated carbon powder is produced by series of processes such as wood chips, sawdust, coconut shells, apricot shell, peach shell and so on. With physical and chemical methods, it is processed by high-temperature carbonization, activation, acid washing or rinsing to form black, odorless, non-toxic activated carbon. It has 600-2000m2/g specific surface and the dual characteristics of physical adsorption and chemical adsorption. It can selectively adsorb various substances from small to large molecules in the gas and liquid phases to achieve the purpose of decolorization, deodorization, disinfection, and decontamination purification.
What is the difference about various wood activated carbon?
For different raw material of wood activated carbon, they have different pore sizes. Coconut shell activated carbon has the smallest pore radius. Wood activated carbon (such as fir wood) generally has the largest pore radius, which are used to adsorb larger molecules, and are almost exclusively used in the liquid phase, such as glycerol and sucrose. Granular activated carbon is used in the field of urban water supply treatment.
What is the applications?
Wood activated carbon is widely used in the deep purification of drinking water, industrial water and wastewater; the separation and purification of various gases; the recovery of organic solvents; the decolorization, deodorization and refining of sugar, MSG, medicine, alcohol, and beverages Refining of precious metals; catalysts and catalyst carriers in the chemical industry.

The main industrial activated carbons of Zhulin Carbon includes:
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.;
Gold activated carbon:
Activated carbon for water treatment, 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.

Edible oil purification activated carbon:
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%.
