The activated carbon market in my country is very large. As a whole, there are many activated carbon manufacturers, and the products are countless. The quality of activated carbon is naturally uneven.


 Whether it is nutshell activated carbon or columnar activated carbon, there are many common identification methods on the market. ningxia yongruida carbon Take columnar activated carbon as an example, the common one is to identify the iodine value of columnar activated carbon, and the quality of columnar activated carbon can be simply measured.


But the iodine value does not completely represent the quality of columnar activated carbon, and density is also one of the important indicators for detecting the quality of columnar activated carbon.


Columnar activated carbon density:

The total amount of columnar activated carbon stacked in a unit volume, generally the better the columnar activated carbon, the more sufficient the pore space, the less the mass of columnar activated carbon stacked in the unit space, and the smaller the amount and weight of columnar activated carbon.


Common density of activated carbon:


The density of columnar activated carbon is generally between 0.5g-0.7g/cm3, the lower the density, the better the quality of columnar activated carbon.


The density of powdered activated carbon is between 0.38g-0.45g/cm3: Because the powdered activated carbon is fine enough and the particles are small enough, the adsorption space of the powdered activated carbon is very abundant, and the relative density of powdered activated carbon is naturally much lower.


The density of nutshell activated carbon is about 0.45-0.65g/cm3. Due to the good pore distribution of raw materials such as nutshell, the density of nutshell activated carbon is naturally much better than other activated carbons.


The density of coal-based activated carbon is between 0.45-0.75g/cm3. Compared with coal products, raw materials such as husks do not have developed pores, so the density of coal-based activated carbon is lower than that of husk activated carbon.


When buying columnar activated carbon and other activated carbons, compare the density of columnar activated carbon, and naturally you can initially determine the quality of columnar activated carbon. www.wyactivatedcarbon.com


The application of columnar activated carbon in industry is irreplaceable. With the progress of technology and the improvement of living standards, columnar activated carbon has begun to enter human life and has a good performance.


Columnar activated carbon has such a good market prospect, mainly related to several advantages:


Columnar activated carbon technology is mature and widely used

Columnar activated carbon can be described as a material that has been used early, popularized, and technologically mature. The application of columnar activated carbon can be traced back to the First World War. china activated carbon manufacturer It was used in military gas masks. After nearly a century of development, the technology has become quite mature and has been used in industry, industry and It has a good effect in environmental protection.


Columnar activated carbon has a long service life

Compared with sprays, although it can temporarily relieve it, it lacks the ability of long-lasting purification. The service life of columnar activated carbon can reach more than one year, which is completely better than spray materials.


Columnar activated carbon is simple and flexible to use

Even if the columnar activated carbon is used in a large area in the industry, it can be directly placed at the pollution source, without deliberate learning and operation. The columnar activated carbon used for households is usually a 50g adsorption bag, which can be adsorbed from the pollution source. It is simple and flexible. Restricted by factors such as site, and the purification capacity is better than most purification products.


Columnar activated carbon can adsorb many substances

Compared with traditional materials, columnar activated carbon has a wide adsorption range, such as common benzene series compounds, formaldehyde, peculiar smell, etc., columnar activated carbon can achieve effective adsorption. At present, there are few purification materials in the city that can be used for multiple purposes.


Columnar activated carbon is safe and environmentally friendly

Columnar activated carbon is very stable and will not react during the adsorption process, nor will it chemically react with organic gases. Pure physical adsorption will not cause secondary pollution. At the same time, it can be regenerated after adsorption is saturated, which meets the requirements of modern environmental protection and is very rare.


Columnar activated carbon is cheap

Columnar activated carbon is mainly processed from coal products, so the price of columnar activated carbon is much lower than other materials, and it is very suitable for modern home use.https://www.coalactivatedcarbon.com


There are thousands of types of activated carbon on the market. The simple way of distinguishing the quality of activated carbon is mainly from the appearance and material. Generally, the adsorption capacity of activated carbon from the shell is stronger than that of coal-based activated carbon, but how to distinguish the shell of the activated carbon with the same specification Charcoal or coal-based charcoal?


The following briefly describes the difference between the two:


Choosing coconut shell activated carbon also belongs to nut shell activated carbon. Because coconut shell has developed pores, light material, and low density, it is a good material for making activated carbon at present. Therefore, coconut shell activated carbon is currently a good activated carbon. coal based activated carbon granular If the same weight of coconut shell activated carbon, Nutshell activated carbon is put together with coal based activated carbon. Coconut shell activated carbon has the largest volume, followed by nutshell activated carbon, and coal based activated carbon is smaller.


The formed coconut shell activated carbon or nut shell activated carbon is mostly broken particles and flakes, showing irregular particles as a whole; most of the coal-based activated carbon is columnar, spherical, etc., and the shape is relatively regular.


Because the shell activated carbon has a low density, a light material, and a larger pore space than coal-based activated carbon, the two can be placed in water for comparison. Generally, because the coal-based activated carbon has a heavier material, it will sink quickly when placed in water; Water will absorb water molecules first, and then slowly sink after the adsorption is saturated. This process is much slower than coal-based activated carbon.


Nutshell activated carbon and coal-based activated carbon will produce bubbles when placed in water, but the bubbles are also different. Nutshell activated carbon has many developed pores, and its bubbles are relatively small and dense; coal-based activated carbon is a macromolecular pore structure, and its bubbles are relatively large and thin.


Although the adsorption capacity of husk activated carbon is stronger than that of coal-based activated carbon, the price of husk activated carbon is much higher than that of coal-based activated carbon. When using it, you need to choose the corresponding activated carbon according to different needs.https://www.powdered-activated-carbon.com


In water treatment applications, all three types of carbon (coconut, coal and wood) are used, depending on the nature of the treated drinking water and wastewater. Therefore, it is necessary to compare various types of carbon according to their specifications.


Porosity plays an important role in choosing the right carbon type. Coconut activated carbon contains many micropores, while coal activated carbon mainly contains mesopores and micropores, while wood activated carbon only contains mesopores and macropores. coal based carbon pellets If the molecular size of the impurity is less than 100 Angstroms, coconut carbon can be preferred. Similarly, if the molecular size of the impurity is between 100 and 1000 angstroms, we can use coal. If the molecular size of the impurity is greater than 1000 angstroms, wood carbon can be considered.


1. Wood activated carbon is most suitable for decolorization in the form of powder.


2. Coal activated carbon is suitable for odor removal.


3. Coconut activated carbon is suitable for dechlorination.


Cost wise coconut activated carbon is a little more expensive than coal and wood activated carbon. "If a given volume of container is to be filled, more weight of coconut activated carbon will be required due to its high density.". But at the same time, due to the high hardness of coconut activated carbon, the material loss in the backwashing process is very small, which can be ignored. Therefore, the operation cost is low.


Coconut activated carbon has high wettability and low ash content. Because it is a renewable resource. carbon pellets supplier It is preferred for drinking water treatment and reverse osmosis water application. Having said that, coconut activated carbon is most suitable for drinking water products.


Coal activated carbon is used in drinking water projects. In addition, there are few other industrial applications, such as wastewater treatment and wastewater treatment. This type of carbon is most suitable for odor removal and cost-effective applications.


Choosing the right form of activated carbon depends on your application and operating costs. Professional guidance is the best way to ensure that the right product is delivered for a specific application.

Activated carbon filters do an excellent job of removing and reducing many different contaminants from water, including chemicals, gases, and physical impurities. Several studies cited by the Environmental Protection Agency in the United States (EPA) and NSF International claim that activated carbon filters eliminate between 60 and 80 chemicals from water, effectively reduce another 30, and moderately reduce an additional 22. Of course, the capacity of the system to remove or reduce those contaminants depends on two things:


Here are several classes of water contaminants that activated carbon filters work to remove and reduce:



Perfluorooctanesulfonic acid, or PFOS for short, is a water and stain-resistant synthetic compound that is widely used to make carpets, fire-fighting foams, furniture, paper packaging for food, clothing fabric, and other materials that are resistant to water, grease, or stains. coal based activated carbon PFOS chemicals are difficult to break down, so they can continue to exist in the environment and drinking water sources for decades. Exposure to PFOS over certain levels can result in adverse health effects, including congenital disabilities, cancers, liver effects, and more. Activated carbon filters are designed to effectively remove PFAS, including PFAS, PFOS, and PFNA.


· Pharmaceuticals

High-quality activated carbon filters can remove pharmaceutical residue in drinking water. The World Health Organization (WHO) defines pharmaceuticals as “synthetic or natural chemicals that can be found in prescription medicines, over-the-counter therapeutic drugs, and veterinary drugs.” These compounds can get into water sources through human waste from persons who have used the chemicals, uncontrolled and improper disposal of drugs (e.g., flushing drugs into sinks or toilets), and from agricultural runoff comprising livestock manure. When accumulated in the environment, pharmaceutical residues can significantly impact aquatic life. What’s even worse is that they can also leach into well water.


· Phosphate

Phosphate in drinking water comes from a range of sources, including runoff, human and pet sewage, chemical manufacturing, and others. www.coconutactivatedcarbon.com Phosphate is crucial for healthy plant growth, but excess phosphate in water can result in a massive increase of algae, causing the water to become cloudy due to algal bloom. Premium charcoal filters usually remove up to 90% of phosphates in water.

Coals are described as porous, heterogeneousorganic rocks that contain small amounts of mineral matter. 4mm activated carbon pellets Generally, they are considered as one of the most important precursors in the production of carbons. Particularly, bituminous coals are the main precursor for the production of activated carbon.


Activated carbon is has many types which include coconut shell activated carbon, coal based activated carbon, wood based activated carbon. But in this article we will dive deep into the category of Coal Based Activated Carbon and learn its importance.


In order to know about Coal Based Activated Carbon, you will first have to know what Activated Carbon is. Preparation of Activated Carbon is done by naturally occurring carbonaceous material such as coal. Coal is heated in low or no oxygen environment to take away water and other impurities. This processed coal is called char.


Char is further physically and chemically processed which increases its surface area and creates large number of microscopic network of pores. This type of pore distribution of coal based activated carbon makes it ideal to remove all sorts of large and small impurities.


The charcoal has to go through couple of stages. The first stage is the carbonation (devolatilization). The second stage is the stage of activation. Carbonization and activation can be also obtained simultaneously by impregnation with dehydrating agents such as Zinc Chloride and Phosphoric Acid.


Coal based activated carbon differentiated into four types of base material i.e. luminous, lignite, anthracite, sub- luminous that consist of mega, micro& macro pore structures.Activated carbons have a large adsorption capacity. granular-activated-carbon.com Activated carbon is used in the purification of air, water, gold etc. Coal Based activated carbon is used in industrial sectors, medical sectors, water treatment and purification etc.


Characteristics OF Coal Based Activated Carbon


· High Quality Raw Coal:High quality of coal is used in making coal based activated carbon. This increases the effectiveness of the product.


· Exceptional Hardness:The hardness of coal based activated carbon effects the quality of the product.


· Excellent Adsorption:Adsorption is a distinct method where organic compounds within water react with activated carbon which traps the particles. The more porous the carbon is, the more contaminants it will capture.


· Low Ash and Moisture:A good characteristic of coal based activated carbon is that it gives away fewer amounts of ash and moisture. This makes the atmosphere healthy.


· High Micro-Porous Structure: Coal based activated carbon has a high micro porous structure which enables a larger amount of impure particles to be trapped.


· Odor Control in Liquid:It helps get rid of the unpleasant odor in liquids.


· Taste Improvisation:Coal Based Activated Carbon improvises the taste of water.

coconut shell activated carbon pellets  is a valuable product which is created out of coconut shell. It is the hardest part of coconut which located inside of coconut husk by protecting coconut meat. Normally coconut charcoal created by the different process of burning coconut shells from a mature coconut. These are mainly used to create active carbon.


Coconut shell is located in between the coconut flesh and coconut husk. Naturally created to protect the inner part of the coconut. It is used to produce various handicraft applications. Most of handmade decorative are created by using coconut shell due to their strength.


Coconut charcoals are far better than other charcoals. Widely used to produce active carbon. Normally active carbon is known as the charcoal which has treated with oxygens. carbon pellets Active carbon is used widely for removing impurities.


Due to its amazing moisturizer and purification qualities, coconut charcoal is also used to create soaps and these types of soaps are sensitive and good for skin also.


Coconut Charcoal Teeth Whitener

It can be used as a natural teeth whitener and this gives an amazing result. Those who are having dark and yellow teeth can use coconut charcoal to brush your teeth and you can get an instant result from this.


Alternate Replacements in Food Industry

Due to the high heating capacity, it’s widely used for barbecue as an alternative for normal coal. Because of its good smell, most of the food producers in the food industry are now tend to use coconut charcoal to prepare traditional foods and barbecues.


Animal Feed

It is used as animal feed for cattle, pigs and other poultry. Studies showed that the cattle use it for their food has increased the milk production rates also. For pigs its use to increase the weights of it and able to reduce the diseases and increase the life of pigs and other poultry animals also.

Magnification of the surface area due to the increasing number of micro pores that have great adsoroption ability is the main purpose of the production of activated carbon. Characteristics of the pores and even then vary depending on the application or use of activated carbon as an example the pores of the activated carbon used in the liquid, will be different which is used in gas substances. Characteristics of the pores can be designed and made during the production process. activated carbon supplier Basically the manufacture of activated carbon will involve high temperatures and adjuvant activating that can be a steam, CO2 or chemical, depending on the characteristics of activated carbon, or more specifically in the pores of activated carbon are generally calculated  by its surface area of the activated carbon. Additionally hardness of activated carbon is also other important quality factors of the activated carbon.


Activated charcoal production requires charcoal as raw material. The charcoal can be produced in both traditional and modern process. Charcoal quality will affect the quality of the final product of activated carboon. Modern charcoal production continuously be able to make the whole process of the activated carbon production becomes efficient when both are integrated into one. In the process of making charcoal which usually need to be cooled beforehand so into charcoal, then it can not be done when the production of charcoal continuously. Results of carbonization directly into the activation unit with only slightly raise its temperature, ie, if the carbonization ranging from 600 C and the activation of about 900 C. When using raw charcoal from the traditional process as a raw material, it takes far more energy to achieve the activation temperature of about 900 C.


Once out of the activation process, the active carbon is cooled by removing a number of considerable heat. Heat is released in large enough quantities can be used for drying coconut shell or palm kernel shell, giving it a special process of carbonization become more efficient as well as a whole with the activation. Activation adjuvant to be inserted in the activation process is well regulated its operating conditions of temperature, pressure and residence time to get the quality and quantity of activated carbon desired. coconutactivatedcarbon.com  In the activation condition, likened charcoal is material be punched by the activation of materials at high heat. There are many variants of activated carbon can be designed specifically for their intended use, so that the operating conditions and auxiliaries activation there are also variations.


The use of activated carbon, especially in the food industry (food) including beverages and pharmaceuticals, precious metals refinery (favor) and the oil and gas industry. Once the extent and magnitude of this use of activated charcoal so it is a great opportunity also for Indonesia, which has the best raw materials are also the largest quantity in the world of coconut shell and palm kernel shell.

Activated carbon or activated charcoal, activated coal or simply active carbon a form of carbon or charcoal processed to have small, low-volume pores, to increase the surface area available for adsorption or chemical reactions.


Generally, the main difference between normal charcoal and activated charcoal is that the latter has its microstructure specially engineered for maximum specific surface and high adsorbtion. Sometimes further chemical treatment is used to enhances adsorption properties.


The most common forms of activated carbon encountered are powder and pellets. The pellet form has the advantage of better mechanical stability and as such is commonly used in various filters.



Activated carbon is a black solid with a grayish luster, with a very high specific surface (500-5000 m2/g). Its high specific surface allows it to adsorb various gasses and liquids, as well as small size particles, a property widely exploited in water purification. While it's generally encountered as a powder, activated charcoal is also available as pellets or beads. It is insoluble in all solvents and will burn in air if ignited, though it does not ignite very easy.



activated carbon pellets is sometimes used as a catalyst in various chemical reactions.



Powdered activated charcoal is sold in various pharmacies. Can also be bought from vet and pet shops.


Gas marks filters tend to contain activated carbon in pellet form.


Some old hard drives also contain activated charcoal as either beads or powder, in a small plastic vial, glued inside.



Activated charcoal can be made from common charcoal or sugar charcoal (made by dehydrating sugar with concentrated sulfuric acid), by treating it with superheated steam (some sources say 800-900 °C) or with hot phosphoric acid. Boiling charcoal in water will also activate it, although this type of activated charcoal, while better than untreated charcoal, is still inferior to the OTC type.www.granular-activated-carbon.com

However, activating the charcoal at home is generally not worth the effort and it's much cheaper to simply just purchase it from the store.
