Introduction to Powdered Activated Carbon

Powdered activated carbon is produced from fine wood chips and nut shells by zinc chloride method. It has the characteristics of developed mesoporous structure, large adsorption capacity and fast filtration.

Powdered activated carbon classification

Powder activated carbon is mainly divided into coal powder activated carbon and wood powder activated carbon.

Coal powder activated carbon

Coal-based powdered activated carbon is made of high-quality anthracite as raw material. It has high chemical composition, more impurities, and ash content is not as low as that of wood-based powdered activated carbon, which cannot meet the national food standards. It will affect the quality and gloss of its products. Coal powder activated carbon is only suitable for chemical industry, sewage treatment, domestic water and other industries.

Wood powder activated carbon is refined from high-quality fruit shells and sawdust as raw materials. The appearance is black fine powder, non-toxic and tasteless, with large specific surface area and strong adsorption capacity. It is suitable for sugar production, pharmaceuticals, beverages, alcohol, etc. In the water purification industry of water quality, it is also widely used in the decolorization, refining, purification and sewage treatment of organic solvents.

Application fields of powdered activated carbon

1. Mainly used in various amino acid industries, refined sugar decolorization, monosodium glutamate industry, glucose industry, starch sugar industry, chemical auxiliaries, dye intermediates, food additives, pharmaceutical preparations and other high-pigment solutions for decolorization, purification, deodorization, removal miscellaneous.

2. It is used in the pharmaceutical industry, fine chemicals, such as decolorization of raw materials, oral medicine (silicon carbide, antidote, colon cleanser), chemical raw materials, pharmaceutical intermediates, chemical raw materials, biopharmaceuticals, biochemical technology, various Decolorization, purification and refining of preparation injection.

3. Applicable to the pharmaceutical industry such as antibiotics, streptomycin, lintomycin, gentamicin, penicillin, chloramphenicol, sulfonamides, alkaloids, hormones, buprofen, paracetamol, vitamin B1, vitamin B6, Vitamin C, metronidazole, gallic acid, etc.

4. It can also be used for decolorization, impurity removal and odor removal of fine chemical products such as glyoxal, benzotriazole, methyl ester and glycerol.

5. It is mainly used for decolorization, refining and removal of "heat source" of various injection drugs. It can also be used for decolorization of vitamin C and other raw materials. It has strong decolorization power and fast filtration speed. And has the effect of absorbing intestinal bacteria and detoxification.

6. It is suitable for decolorization of sewage in chemical industry, sewage treatment, domestic water and other industries.

Preparation method of powdered activated carbon

Powdered activated carbon is made of fine wood chips or anthracite as raw materials, and is refined by special production process. There are two kinds of physical method and chemical method. After being activated by water vapor, it is refined and crushed.

The process flow of powdered activated carbon is as follows:

1. Screening and drying of sawdust and anthracite.

2. Ingredients and dipping.

3. Put the plate into the furnace for activation.

4. Recycling and rinsing.

5. Centrifugal dehydration, drying and grinding.

6. Enter the packaging process and warehouse storage.

physical law
