Introduction of granular activated carbon, the role of activated carbon Uses of activated carbon

The ** of granular activated carbon is about a few thousand yuan per ton, and the cheap one is one or two thousand yuan. Different types of granular activated carbon** are also different. In terms of categories, granular activated carbon is divided into coconut shell granular activated carbon, coal-based granular activated carbon, and fruit shell granular activated carbon according to the raw materials for production.

Coconut shell granular activated carbon, coconut shell granular activated carbon is made of high-quality coconut shell as raw material and refined by a series of production processes. The appearance is black and granular, which has the advantages of developed voids, good adsorption performance, high strength, economy and durability. The products are mainly used for purification, decolorization, dechlorination, deodorization, desiccant, catalytic carrier, etc. of drinking water, purified water, tap water, wine making, beverages, and industrial water.

Fruit shell granular activated carbon, fruit shell granular activated carbon is made of peach shell, apricot shell and other kernel shells as raw materials, and is refined by a series of production processes....

Granular activated carbon is divided into stereotyped and amorphous granules. It is mainly made of coconut shell, fruit shell and coal as raw materials, and is refined by a series of production processes. The products are widely used in drinking water, industrial water, winemaking, waste gas treatment, decolorization, desiccant, gas purification and other fields.

Granular activated carbon is made of high-quality anthracite as raw material, refined and processed by advanced technology, and the appearance is black amorphous particles; It has the characteristics of well-developed pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration, and low cost; It is used for the purification of toxic gases, waste gas treatment, purification of industrial and domestic water, solvents, etc.

1. The role and efficacy of activated carbon Activated carbon is also known as activated carbon black. It is amorphous carbon in the form of black powder or granules. Eyes on the branches.

2. Activated carbon has a strong "physical adsorption" and "chemical adsorption" effect, which can adsorb some organic compounds and achieve the removal effect.

3. The main hole of activated carbon is used: new room: used to adsorb formaldehyde, benzene, ammonia and radon and other toxic and harmful gases in the air in the air and continuously released into the air.

4. The role of pharmaceutical activated carbon: the biggest feature of pharmaceutical activated carbon is that it has fast decolorization speed, strong adsorption capacity and can effectively adsorb.

Activated carbon is also known as activated carbon black. It is amorphous carbon in the form of black powder or granules. In addition to carbon, the main component of activated carbon is oxygen, hydrogen and other elements, which is the reason why activated carbon is a hydrophobic adsorbent.

Activated carbon uses.

In terms of elemental composition, more than 80%-90% of activated carbon is composed of carbon, which is why activated carbon is a hydrophobic adsorbent. In addition to carbon elements, activated carbon also contains two kinds of admixtures: one is the chemically bound element, mainly oxygen and hydrogen, these elements are due to incomplete carbonization and remain in the carbon, or in the activation process, the foreign non-carbon element is chemically combined with the activated carbon surface, such as when activated with water vapor, the activated carbon surface is oxidized or oxidized by water vapor; Another type of admixture is ash, which is the inorganic part of activated carbon, which is composed of several elements of activated carbon.

With the continuous development of the activated carbon industry, more and more industries and enterprises have used activated carbon, and some companies have entered the activated carbon industry. The role of activated charcoal.

Activated carbon is generally used for filtration and decolorization, as a reducing agent and as an absorbing gas. According to its application field, the specific role of activated carbon is different. For example, during World War II, activated charcoal was used in gas masks; Tap water can be deodorized with activated carbon; Used at home, activated carbon can purify the air and remove harmful substances.

It is precisely because of this series of advantages of activated carbon that many families have also begun to use activated carbon to improve the air quality in their homes. Granular activated carbon is often used for adsorption molecules, and the adsorption of granular activated carbon determines the applicability, and the adsorption is related to the pore size distribution of various carbon types. Take, for example, water vapor-activated peat-based, lignite-based, and coir-based powdered activated carbons

Pea-based activated carbon is microporous and mesoporous, and granular activated carbon can be used for a variety of applications; The lignite-based carbon has more mesopores, and the granular activated carbon also has large mesopores, providing excellent accessibility; Coir-based granular activated carbon is mainly microporous, which is only suitable for the removal of low molecular weights.

The role of activated charcoal.

Chemical-activated granular activated carbon is very porous, mostly in the microporous and mesoporous ranges, but the pore surface of water-vapor-activated activated carbon and chemical-activated activated carbon is less hydrophobic and more negatively charged. Take extruded and crushed granular activated carbon as an example: peat-based extruded activated carbon can be made into a variety of varieties with different pore size distributions.

The microporous varieties of granular activated carbon are mainly used for gas application. Most of the varieties with both micropores and mesopores are used in liquid phase applications, such as the adsorption of small and macromolecular impurities in water purification. Crushed briquette-based granular activated carbon is available in both microporous and mesoporous applications for a variety of purposes.

Lignite-based or coir-based granular activated carbon has the same microporous and mesoporous structure as powdered carbon. The technical indicators of activated carbon are very important: the performance indicators of activated carbon products can be divided into physical performance indicators, activated carbon chemical performance indicators, and granular activated carbon adsorption performance indicators.

The three performance indicators play a very important role in the selection and application of activated carbon. The main physical properties of activated carbon are: shape, appearance, specific surface area, pore volume, specific gravity, mesh, fineness, wear resistance, floatation rate, etc.

The main difference between granular activated carbon and columnar activated carbon is the shape!

Columnar activated carbon is mainly made from raw coal, i.e., anthracite.

Mainly divided by diameter size, commonly used specifications are 1mm, these four! ** Words are divided by iodine value!

There are two kinds of granular activated carbon as raw materials: coal-based granular activated carbon and fruit shell granular activated carbon (for example: coconut shell activated carbon, etc.).

The specifications of granular activated carbon are generally based on the number of meshes as a reference, and 8-16 meshes are the conventional sizes! Other specifications can be customized!

Their applications are similar, columnar activated carbon is biased towards air adsorption! Granular activated carbon has a wide range of applications in air adsorption and water treatment!

First of all, judging from the name, their physical traits are different.

The picture above is granular activated carbon, and the picture below is columnar activated carbon.

3.In terms of the field of application, there is basically no difference. Some people say that particles are suitable for gas or liquid phase filtration, and some say that they are columnar.

It is not particularly prepared, whether it is granular or columnar, as long as their micropores, medium pores, and macropores meet the requirements of the corresponding scene, they can be used.

Granular activated carbon is an irregular round particle, usually between 3 mesh and 100 mesh, and there are also broken flakes (such as coconut shell charcoal).

Columnar activated carbon is cylindrical, usually in mm The common application field of 2-4mm is actually similar, mainly according to the requirements of the specific enterprise of the application. In practice, there will be all differences due to the differences in the accumulation and load-bearing conditions, as well as the parameters of the specific activated carbon itself.

Fujian Xinsen Carbon Industry Co., Ltd. has a specific specification table, you can go up and down.

Columnar activated carbon has the effect of removing odors, if you just want to get rid of odors, it is recommended to use coconut shell activated carbon! This is a professional deodorant.
