Generally speaking, the greater the specific surface area (BET) of coconut shell activated carbon, the greater the adsorption capacity; but sometimes it is not necessarily.https://www.powdered-activated-carbon.com/
BET is a widely used parameter for measuring the total surface area of coconut shell activated carbon by nitrogen or butane adsorption. It stands to reason that the larger the BET, the greater the adsorption force.
However, this concept has limitations in practical applications, because the pores of coconut shell activated carbon have the difference between macropores, mesopores and micropores. Sometimes only part of the pores are suitable for the entry of certain types of adsorbents, so the total surface area and Porvolume data (for example, the total surface area is usually about 450-1 80Om2/g and the pore volume is about 0.7-1.8 ml/g) cannot be used to evaluate the effectiveness of the adsorbed coconut shell activated carbon. Most of the total surface area belongs to micropores. The typical data is: micropores account for 1000m2/g, mesopores account for 10-100m2/g, and macropores account for lm2/g.
In liquid phase applications, the adsorption of organic matter generally increases with the increase in molecular weight (molecular size). Until the molecule is too large to enter the hole. Many high-molecular-weight organics, such as colored substances or humus, are excluded from the micropores. In this case, coconut shell activated carbon with more mesopores needs to be used, while microporous carbon with high total surface area is powerless.
The most ideal coconut shell activated carbon has a large number of pores just slightly larger than the adsorbate molecules. If the pore is too small, the adsorbent cannot enter; if the pore is too large, the surface area per unit volume is reduced. It is best to encounter molecules with a molecular weight between 300 and 100,000, which is equivalent to a pore size between 0.5 and 4 nm, and darker pigments are often larger molecules.
In gas phase applications, small molecules are adsorbed into human pores. At this time the concept of total surface area is applicable. For example, the recovery of solvents in the air or the prevention of gasoline escape in cars.
As for the adsorption of metal complexes by coconut shell activated carbon, it involves the formation of chemical bonds, and it is not that the larger the BET, the better. For example, from the solution of gold cyanide adsorption, the coconut shell activated carbon of the steam activation method has a high affinity for gold cyanide, while the coconut shell activated carbon of the chemical activation method has no affinity even if it is porous.https://www.granular-activated-carbon.com/

Introduction to the carbonization principle of columnar activated carbon: activated carbon products always go through the two steps of carbonization and activation, and columnar activated carbon is no exception. Today, let me introduce the principle of carbonization of columnar activated carbon.https://www.wyactivatedcarbon.com/
How is the columnar activated carbon carbonized?
The carbonization method is first to use the columnar activated carbon carbonization furnace to preheat through the preheating stage, then enter the carbonization stage to heat at a high temperature of four to five hundred degrees, and then use air to support combustion without adding other items as fuel, and then enter the cooling stage for cooling.
The carbonization principle of columnar activated carbon:
In the initial stage of use of the columnar activated carbon, its micropores will gradually be filled with air and small molecular substances. With the extension of the adsorption time, the columnar activated carbon will increase its ability to absorb large molecules, and the adsorbed small molecules will be replaced by large molecules.
Specific analysis: The columnar activated carbon is processed by technically subdivided pore size and catalyst molecule coating to enhance the purification ability of the columnar activated carbon for harmful substances in the air. Purification principle of columnar activated carbonIn the initial stage of use of columnar activated carbon, the micropores of the carbon are gradually filled with gases including air and other small molecular substances. However, as the adsorption time increases, because carbon has the characteristic of adsorbing large molecular gases, carbon The adsorbed air and other small-molecule gases are gradually replaced by macromolecular formaldehyde, benzene, tvoc and bacterial cluster particles.https://www.wyactivatedcarbon.com/products/granular-activated-carbon/

Activated carbon has always been a hot commodity in the pharmaceutical and chemical markets, and the demand is great. However, the production of activated carbon produced in our developing country is not enough at all, and the output can only meet 50% of the demand, and the price is rising year by year.https://www.wyactivatedcarbon.com/
However, it is worthy of our attention that due to the shortage of activated carbon resources, after a long period of time, medical drugs produced with activated carbon as the main raw material have been lying in the laboratory obediently, and therefore there has been no product on the market or mass use. In clinical.
With our increasing awareness of health care and quality of life, as well as the rapid development of the industry, activated carbon and medicines and some health products produced with activated carbon as the leading raw material will become the conventional leading consumer drugs in the pharmaceutical market. Because of this, market demand quickly became an upward trend, and it has also become a new economic growth point in the pharmaceutical and chemical markets.
Activated carbon is composed of countless small pores. It has a huge surface area, super adsorption capacity, and can adsorb various organic compounds. Therefore, it is also widely used in the pharmaceutical industry and the chemical industry.
However, activated charcoal is also an efficient gastrointestinal cleaner. It can effectively adsorb heavy metals, residual pesticides, dioxins, various pathogenic bacteria and their toxins in the digestive tract and the human body, which seriously damage human health or cause disease. The waste is not harmful to the human body.

Physical activated carbon
Using carbon as raw material, water vapor, carbon dioxide, air (mainly oxygen) or their mixture (flue gas) is used as the activation medium, and the method of preparing activated carbon by activation at high temperature (600-1000°C) is called physical method. Activated carbon manufactured by physical method is called physical activated carbon, also known as physical carbon.https://www.chinactivecarbon.com/
Generally speaking, physical carbon has developed micropores (pores with pore diameter or pore width less than 1.5 nanometers), which are mainly used for gas phase adsorption or small molecule liquid phase adsorption. Activated carbon produced from different raw materials has different pore diameters. Among them, the pore diameter of coconut shell is small, the pore diameter of wood activated carbon is generally larger, and the pore diameter of coal-based activated carbon is between the two.
The pore size of activated carbon is generally divided into three categories: macropores: 1000-1000000A transition pores: 20-1000A micropores: 20A According to the above characteristics, it can be seen that for different adsorption objects, the corresponding activated carbon needs to be selected to achieve a good cost performance. Therefore, in liquid phase adsorption, activated carbon with more transition pores and larger average pores should be used.
According to the appearance shape: generally powdered activated carbon, granular activated carbon, unshaped granular activated carbon, cylindrical activated carbon, spherical activated carbon, and other shapes of activated carbon.
General physical methods mainly produce coal-based activated carbon and nutshell activated carbon.
Activated carbon made from coal is usually activated by water vapor or carbon dioxide gas. The shape of the product is mainly granular, and its pore size distribution is mostly micropores. It is more suitable for liquid phase adsorption and gas phase materials with smaller molecular weight and molecular diameter. . Its advantage is that the production cost is relatively low;
Activated carbon made from nut shells is usually activated by water vapor and carbon dioxide gas. The shape of the product is mainly granular. Due to its special material, its pore size distribution is between the above two types of activated carbon and has excellent adsorption performance. Therefore, its application range is wider.https://www.coalactivatedcarbon.com/

Activated carbon starts with organic materials with high carbon content (such as coal or wood). The material is slowly heated under high temperature and low oxygen environment, and burning is not allowed. Instead, the material dries, releasing impurities and water. The resulting product is called charcoal.https://www.powdered-activated-carbon.com/
Next, the carbon undergoes various chemical and physical processes to greatly increase its surface area and create a fine pore network. Carbon molecules naturally attract and bind a variety of chemical compounds, and a large amount of surface area provides enough molecular binding sites.
Depending on the application, activated carbon can be used alone or impregnated with chemicals to enhance its ability to bind to target compounds. Impregnation can help improve its effectiveness against a wider variety of impurities and toxic substances.
Activated carbon in water purification
Activated carbon is used at multiple levels in the water treatment process. It is used to filter drinking water at household consumer and municipal level to remove pollutants such as organic matter, pesticides and herbicides.
Activated carbon in the treatment of industrial wastewater
In this application, activated carbon removes dangerous organic and harmful odor-producing substances, returning the waste to a safe state before disposal or reuse. It is usually part of a multiple treatment method that ensures groundwater protection.
Activated carbon air purification
Activated carbon is used to purify the air in many important aspects. Honeycomb activated carbon is generally used here. An example of industrial use is the cleaning of biogas as a by-product of the natural decomposition process. They tend to collect toxic volatile organic compounds (VOCs) and other by-products, such as by-products from the degradation of shampoo in landfills, in landfills, dairy farms and similar places.https://www.granular-activated-carbon.com/

Protect the mattress. In summer, when the air is humid, the dead corners of houses such as mattresses are prone to damp, which will corrode the bed board over time. Honeycomb activated carbon can be placed in the bed board to keep the bed board clean and tidy, and to remove the sour smell of sweat.
Maintain the bathroom environment. Places such as toilets are places where peculiar smells are long-term breeding. Honeycomb activated carbon has a good adsorption effect on harmful gases and also has an effect on peculiar smells. Placing honeycomb activated carbon can keep peculiar smell and bacteria in the toilet.https://www.wyactivatedcarbon.com/
Elemental composition of activated carbon
2020年11月24日In addition to carbon, the element composition of activated carbon also contains oxygen, hydrogen and other elements. Most of the oxygen and hydrogen elements in activated carbon form a chemical combination with carbon to form surface oxides. Other elements mainly constitute the ash content of activated carbon. The content of various elements in activated carbon is related to the raw materials used and the process conditions for producing activated carbon.
Carbon element
Carbon is the main element in activated carbon. The content of carbon in wood activated carbon is usually more than 90%, and it increases with the increase of the activation degree. The presence of carbon has a decisive influence on the properties and structure of activated carbon. The microcrystalline structure formed by it brings porosity to activated carbon; the type and quantity of surface compounds formed by it and hydrogen and oxygen have great effects on the surface properties of activated carbon such as hydrophobicity and hydrophilicity. Impact.https://www.coalactivatedcarbon.com/
Oxygen and hydrogen
The elite elements of oxygen and hydrogen are the main elements other than carbon in activated carbon. These two elements are present in different degrees in all activated carbons.
The oxygen and hydrogen contained in the raw materials are not completely removed during the carbonization activation process and remain, and they are the main sources of these two elements. In addition, air and water vapor will inevitably exist during the carbonization activation process, which is also one of the possible sources of oxygen and hydrogen. As the activation temperature of carbon increases, the content of oxygen and hydrogen in activated carbon decreases. However, even if the temperature rises above 1,000 degrees Celsius, they cannot be removed from the activated carbon.
The two elements of oxygen and hydrogen usually form surface compounds on the surface of activated carbon, which will affect the adsorption performance of activated carbon to a certain extent.
Ash
Ash is the inorganic part of activated carbon, and its content and composition are greatly affected by the types of raw materials, and to a certain extent by the process conditions used in the manufacture of activated carbon.
The chemical composition of ash is relatively complex, usually composed of oxides, carbonates, and silicates of many elements.https://www.chinactivecarbon.com/

The phosphoric acid method is to impregnate wood chips with phosphoric acid and produce activated carbon in a mechanical activation furnace. Compared with zinc chloride, the advantages of phosphoric acid method are:
1 High yield of activated carbon
2 The activation force is large, that is, the quality of activated carbon produced by the phosphoric acid method is relatively better than that of the zinc chloride method
3 It is easy to be refined without washing with hydrochloric acid
4 There is no need to use expensive gas recovery equipment. The hydrochloric acid gas volatilized by the zinc chloride method is harmful to humans and animals, so some funds must be invested to deal with these gases.
But the phosphoric acid method also has its own shortcomings;
1 Phosphoric acid is more expensive than zinc chloride;
2 Phosphoric acid is very corrosive at high temperatures, so the loss of equipment is quite serious. Increase the cost to a certain extent.https://www.powdered-activated-carbon.com/
In the process of activation, 3-4% of phosphoric acid will be evaporated, and 3-4% of phosphoric acid will be lost in the contact process of the equipment. At present, the problem of phosphoric acid production is that phosphoric acid is gradually separated from wood chips with the increase of temperature in the activation furnace and directly contacts with equipment materials to generate metal salts.
For example, using heat and acid corrosion resistant nickel-based composite metal as iron plate material can basically control the loss of phosphoric acid.T
The high cost of this material is not conducive to promotion. Therefore, solving the corrosion problem of phosphoric acid in the activation process and the recovery and reuse of phosphoric acid will be an important subject of the phosphoric acid process.https://www.granular-activated-carbon.com/

Installing your own filtration system can help, and a charcoal water filter is one of the best options. Here is how it works and why you will benefit from using one in your home.https://www.wyactivatedcarbon.com/products/granular-activated-carbon/
Regular charcoal, like that used for grilling, contains toxins unfit for human consumption. Activated charcoal contains natural elements and is processed at an incredibly high degree of heat to produce an especially porous result.
The porous texture contains a negative electrical charge, which causes it to attract molecules that are positively charged, such as toxins. The process of adsorption, unlike absorption, is what allows chemicals binding to occur so that toxins are attracted to the charcoal and then held within the porous cavities until the charcoal becomes full and is expelled.
Activated charcoal has numerous health benefits when ingested by humans, such as whitening teeth and detoxifying the gut. The porous composition of it binds toxins and other compounds to itself. Then both the activated charcoal and the bound toxins are released with the other waste your body naturally expels.
It has been used effectively in medicine for years to counteract poisoning and drug or alcohol overdose. Its efficacy in human detoxification translates into charcoal filters for water.https://www.wyactivatedcarbon.com/

Activated carbon in sewage treatment
2020年11月7日Wastewater treatment is a critical component of any industrial process because it must ensure discharge standards and meet process requirements because water needs to be reused at facilities or elsewhere. As the reuse of water becomes more and more important, activated carbon plays an important role because of its versatility.
Industrial wastewater usually contains many impurities, such as dissolved and insoluble substances, degradable or persistent organic substances, heavy metals and salts. Activated carbon eliminates these harmful substances.https://www.yrdcarbon.com/products/
Activated carbon can be used in water and wastewater treatment because of its adsorption characteristics. Adsorption process is usually used in municipal drinking water treatment to remove synthetic organic compounds (SOC), organics causing taste and odor, color forming organics and precursors of disinfection by-products (DBP).
PAC (powdered activated carbon) and GAC (granular activated carbon) have their advantages and disadvantages in the field of wastewater treatment. According to ASTM, PAC is particles passing 80 mesh (0.177 mm) or smaller sieve. According to the specific application, by changing the manufacturing conditions, the pore structure can be changed by giving each product unique adsorption properties.
PAC is usually used in biological processes to remove toxic organic elements. Carbon in the biological treatment process acts as a "buffer", which can resist the influence of toxic organic compounds in wastewater. PAC can stabilize the biological system from discomfort and shock load, and can control color and odor. Because it supports cost reduction in many cases, it can reduce treatment costs and remove soluble organic matter.
When GAC is used, the tower is usually used as a means of contact between the water to be treated and the activated carbon, so that the water enters through the lower part and rises to the top. In this case, the particle size is larger than other particle sizes. The porous nature and large surface area of GAC make it particularly suitable for physical adsorption and other treatment technologies. It is usually used to remove trace elements, especially organic trace elements, that may exist in water and are usually difficult to be biologically treated. In spite of their low concentrations, these elements usually give water an unpleasant smell, color or taste. Therefore, it is obvious that PAC has more advantages than GAC. But GAC has a very attractive option to reuse by reactivating it.https://www.coconutactivatedcarbon.com/
Moreover, as statutory regulations become more stringent, plans to face current and future regulations cannot be ruled out. In order to meet these challenges and regulations, operators should continuously and rapidly find new technologies and their respective suppliers without neglecting appropriate research and testing to ensure the best wastewater treatment methods.

Do you know which charcoal would be best
2020年11月7日What is Activated Charcoal Made From?
Activated charcoal can be made from a wide variety of media such as wood, coal, bamboo, coconut, pecan, and walnut shells and so much more. If you lived where there was an abundance of coconut shells and or bamboo, then most likely you would have an affordable access to charcoal made from these natural resources. In Australia they have access to eucalyptus trees and some people think that the charcoal from these trees is simply the best. Perhaps they had a wound or an upset stomach, used the eucalyptus charcoal powder and it worked perfectly, so why in the world would they use anything else? As the old saying goes, don’t try to fix something that isn’t broken, right?https://www.granular-activated-carbon.com/
Why is Knowing the Differences Important?
Let’s take an easy example, tires. Why would you want one tire over another? They get you from point A to point B, so they are all the same, or are they? Obviously there are tires that are better for certain applications, such as large tread tires for off road exploration, wide tread for snow, multi-type tread tires for all weather use, smooth tires for racing and of course the quality of the tires, how well will a particular tire perform over other brand tires.
Activated Charcoal all does the same thing, draws and adsorbs toxins and poisons. However, each type that we carry has, in our experience, unique properties that make it ideal for various applications in both commercial and consumer settings.https://www.activated-carbon-pellets.com/
Charcoal’s Many Applications
A good share of the differences in activated charcoal tends to be more applicable to industries that use charcoal for air, water or other liquid purification or to remove unwanted colors, odors or toxins. And because we service a lot of manufacturing industries we want to carry charcoals that will best suit their many needs as well.
For instance, if you called us up and needed something to remove color from a juice, or a supplement do you know which charcoal would be best? If you guessed the hardwood you are right.

Corundum is widely used in abrasives and refractory materials it is also called carborundum, refers to brown fused alumina, white corundum, black corundum, or brown fused corundum, white aluminum oxide, black fused alumina. In general, fused corundum often used for abrasive sandblasting grit, water jet cutting, and terrace industries. So we call all these corundum used in industry carborundum. But in fact some are natural corundum, some of them are artificial corundum. So Here we will talk about the differences between natural and artificial corundum.https://www.hslabrasive.com/
First, the composition of natural corundum and fused corundum are different.
The main ingredient of natural corundum is Fe-Al silicate. In addition, It contains TiO2, MgO, FeO, CaO, MnO, and so on. The natural diamond is the outcome of a series of geological . The main ingredient is artificial corundum Al2O3, is produced by the sand and large amount of carbon heated in an electric furnace.
Second, the hardness of natural corundum and fused corundum are different.
Hardness of natural corundum is high in non-metallic material, second only to diamond and corundum in nature, Mohs 7.0-8.5. The hardness of natural corundum is between 7.5-8.0. Its usage is relevant with the hardness. Artificial corundum hardness is about 9.5 Mohs. Although it is harder than the former, the price is several times of the former. However, using the former can achieve good performance.
Third, the color of natural corundum and fused corundum are different.
Natural corundum has a various kind of colors, the most common color is red and pink. As for industrial using, is generally almandine garnet. The fused corundum also in brown, white and black color.
Fourth, the usages of natural corundum and fused corundum are different.
Compare with natural corundum, the artificial corundum, such as brown fused corundum, white aluminum oxide, black fused alumina are mainly used in abrasive tools, sandblasting grit, refractory materials. https://www.hslabrasive.com/products/iron-sand/

Why use activated carbon in beauty products?
2020年10月31日While the proven health care benefits are obvious, it might not be immediately clear why you want it in your beauty products. Here are just a few of activated charcoals benefits in this area.https://www.wyactivatedcarbon.com/
One of the key skin care benefits of charcoal powder is its ability to draw out toxins and chemicals for easy removal. Anyone suffering from acne knows the value of removing dirt and impurities from the skin to cut down on blemishes and clear your complexion. Activated charcoal applied directly to problem areas or used as a scrub is a highly effective acne treatment without relying on harsh or over drying cleansers, toners, scrubs, etc. This makes is a great addition to soap, sugar scrubs and face masks.
It may be time to add charcoal to your oral health care routine. Many have reported the dramatic whitening effects of using activated charcoal on teeth! It’s said that the charcoal draws the plaque off teeth and removes stains leaving them brighter and whiter. You can apply the powdered form directly to brush your teeth. Prepare yourself though, seeing youth mouth essentially blacked out can be a little disturbing at first and using the charcoal powder straight tends to make a bit of a mess of the sink area. It all rinses away though and whiter teeth and a fresh healthy mouth are worth the extra clean-up. Activated charcoal toothpaste is a bit less messy and typically includes other helpful ingredients as well, such as coconut oil and baking soda.
Activated charcoal benefits your hair too! It be a terrific hair treatment. If you suffer from an oily scalp or you’re an infrequent washer, applying a paste of activated charcoal powder to your scalp can remove build-up and other impurities. It is a fast and effective way to clear out especially strong styling products from your hair and scalp and can even be used instead of traditional shampoos.https://www.activated-carbon-pellets.com/

Activated charcoal is a fine powder made from natural, carbon-containing substances, like wood, willow peat, bamboo, coconut husk and the like. https://www.granular-activated-carbon.com/ The carbon is basically processed to have small, low-volume pores that increase the surface area available for adsorption. There are two ways to activate carbon:
1. Chemical activation – the carbon is treated with a chemical activation agent, like phosphoric acid, and then heated to a temperature of 450-700°C. The char is then washed with water to remove the acid from the carbon. The carbon is then dried and eventually made into powdered carbon.
2. Physical (Thermal) activation – the carbon is pyrolized in an inert environment, then activated in an oxidizing environment under extreme heat. Natural brands utilising activated charcoal in their products generally prefer this method as no harsh chemicals come into contact with the carbon.
Activated charcoal is very porous and highly adsorbent (meaning materials adhere to its surface). When used as a tooth powder or in toothpaste, it binds with surface stains caused by things like tea, coffee, wine and tobacco. In this way, activated charcoal can help remove day to day plaque and stains from the surface of your tooth enamel, revealing the natural colour of your enamel which, hopefully, is whiter.
Results vary from person to person and can be affected by factors like your eating and drinking habits and the type of stains on your teeth. Whilte some people see results in as little as one week, most people will notice improved whitening of their teeth within 2-3 weeks. https://www.coconutactivatedcarbon.com/ Results can also vary between using activated charcoal powder and using toothpaste containing activated charcoal. But some people just have naturally yellow teeth.

Prices for brown and white fused alumina increased through the first half of September 2019 amid concerns over Chinese supply with the continuing threat of environmental inspections and plant closures. Prices for calcined alumina, meanwhile, have fallen further in recent weeks with increasing supply but little increase in demand. Concerns remain, however, over Chinese supply of bauxite as feedstock for calcined alumina production.https://www.hslabrasive.com/products/fused-alumina/brown-fused-alumina.html
Supply of Chinese bauxite and alumina has suffered from environmental shutdowns for a number of years. Bauxite prices peaked in early 2018 and saw increases through early 2019 following environmental shutdowns in Shanxi province. During the first half of 2019, all bauxite mines in the Xiaoyi area of Shanxi were closed and there was a period of no raw material bauxite availability for any use in the region.
Alumina has not been immune to the effect of enforcement of environmental legislation, but its supply is from a much wider range of sources and China has less influence on world supply and demand.
Refractories are by far the largest application for calcined alumina and are an important application for non-metallurgical bauxite. Refractory demand is relatively weak, mirroring trends in the global steel market. Bauxite and alumina products are also used widely in cement, abrasives and ceramics applications, however, which continue to show higher levels of growth.https://www.hslabrasive.com/products/fused-alumina/
