Activated carbon is a highly multipurpose material that finds its application in a wide range of industries. How to make activated carbon? the answer is activated carbon plant. As a form of carbon that has been treated with oxygen, the activation process increase its surface area and make it highly porous, allowing it to trap and absorb various substances effectively. This unique property makes it a go-to solution for various applications such as water treatment, air purification, and gas separation.
Choosing the right type of activated carbon for specific applications is very important for users. Different types of activated carbon vary in their properties, such as surface area, pore size, and hardness, making them suitable for specific applications. Today we will helps you find the most suitable type.
Powdered activated carbon (PAC), granular activated carbon (GAC), pelletized activated carbon (PAC), and honeycomb activated carbon (HAC) are the four most commonly used types of activated carbon, each having their unique properties and applications.
It is essential to understand the properties and applications of different types of activated carbon to choose the right type for specific applications. Choosing the wrong type can result in low efficiency and unwanted outcomes. In the next sections, we will provide detailed information on the different types of activated carbon and their specific applications.
Types of Activated Carbon
Powdered Activated Carbon (PAC)
Powdered activated carbon (PAC) is a finely ground powder with high surface area, it can effectively absorb various impurities in water, air and other media. It is produced by grinding activated carbon to a size less than 0.075mm, resulting in a product with high surface area and low flow resistance. PAC is widely used in water treatment, food and beverage and air purification industries due to its effectiveness in removing organic compounds, disinfectants and other impurities.
One of the most important benefits of powdered activated carbon is its high surface area to volume ratio, which helps it absorb impurities quickly and efficiently. The powdered activated carbon production process includes grinding the activated carbon into a fine powder, resulting in a product with a surface area of up to 2500 m2/g. With its low flow resistance properties, powdered activated carbon is used in high flow applications.
powder activated carbon is widely used in water treatment industry to remove organic compounds, disinfectants and other impurities. It is usually used in the form of a slurry, which is added to the water to be treated. PACs can remove impurities from water by adsorption, which is a process by which impurities are attracted to the surface of the PAC particles and held there. PACs are also used in the food and beverage industry to remove color, odor and taste from water used in the manufacturing process.
One of the main disadvantages of powder activated carbon is its potential to cause damage during handling and transportation due to its fine particle size. In addition, PAC has a relatively short lifespan compared to other types of activated carbon, which can lead to increased replacement and disposal costs.
Granular Activated Carbon (GAC)
granular activated carbon (GAC) is a granular form of activated carbon. In general, granular activated carbon is used in various industries for gas and vapor adsorption, water treatment, and air purification. as we all know, granular activated carbon is produced by carbonizing organic material, such as coconut shells, wood, or coal, at high temperatures, followed by activation process with steam or chemicals. The resulting product has a high surface area and is highly porous, allowing for efficient adsorption of impurities.
granular activated carbon is widely used in the gas and vapor adsorption industry due to its high surface area and the ability to adsorb a wide range of organic and inorganic compounds. GAC is used in air purification systems, where it can adsorb volatile organic compounds (VOCs) and other pollutants, resulting in cleaner air. It is also used in the water treatment industry for removing organic compounds, disinfectants, and other impurities. In addition, GAC is used in the beverage industry for removing unwanted tastes and odors from water used in the production process.
versatility is one of advantages of granular activated carbon, as it can be used for various applications, such as gas and vapor adsorption, water treatment, and air purification. Additionally, GAC has a longer lifespan compared to other types of activated carbon, which can result in lower replacement and disposal costs. GAC is also relatively easy to handle and transport due to its larger particle size.
Pelletized Activated Carbon (PAC)
Activated carbon that is made as pellets is known as pelletized activated carbon (PAC). Due to its high surface area and porosity, it is used in a variety of sectors, including wastewater treatment, air purification, and gas-phase applications. The manufacturing process of pelletized activated carbon involves carbonization, and activation raw materials with steam or other chemicals. The finished item is then pelletized to produce a consistent dimension and shape.
In the wastewater treatment business, pelletizer activated carbon is often used to eliminate pollutants like organic compounds, disinfectants, and other pollutants. It can adsorb volatile organic compounds (VOCs) and other pollutants, and is also used in air purification devices. pelletized activated carbon can be also used in gas-phase as well, especially purge gas streams of impurities.
Since unique form of pelletized activated carbon, it is simple to handle and use. so pelletized activated carbon is simple to manage, transport, and use in a variety of applications. Due to its high surface area and porosity, PAC is also very efficient at adsorbing a variety of impurities. Additionally, PAC can save money on replacement and disposal expenses because it lasts longer than other kinds of activated carbon.
The use of PAC does have some drawbacks, though. For instance, in some applications, its pelletized form might cause a greater pressure drop and lower efficiency. Additionally, when compared to other forms of activated carbon, PAC might not be as efficient at eliminating specific impurities.
Honeycomb Activated Carbon (HAC)
A special kind of activated carbon with a large surface area and high adsorption capability is honeycomb activated carbon (HAC). To create an extremely porous carbon material, carbonization and activation are combined during manufacturing.
The honeycomb structure is impregnated with a carbon substance during the production of HAC, which is then calcined at high temperatures to carbonize the structure. To produce a highly porous structure with a substantial surface area, the charred structure is then activated using steam or other chemicals.
honeycomb activated carbon has many applications in lot of industries including environmental protection, chemical industry and gas separation. In the environmental protection industry, honeycomb activated carbon is applied for wastewater treatment, air purification, and removal of volatile organic compounds (VOCs) and other pollutants. In the chemical industry, honeycomb activated carbon is used to purify gases, solvents, and other chemicals, while in the gas separation industry, it is applied to separate gases, such as nitrogen and oxygen.
HAC’s high adsorption capacity and ability to successfully remove impurities are two of its key benefits. It is more effective at adsorbing impurities than other kinds of activated carbon because of its distinct honeycomb-like structure, which has a larger surface area. Additionally, HAC has a high resistance to mechanical and abrasion harm, which lengthens its lifespan and increases its durability.
Nevertheless, using HAC has some drawbacks as well. For instance, in comparison to other forms of activated carbon, it might not be as effective at eliminating certain kinds of impurities. HAC can also be more costly when compared to other forms of activated carbon, which may not be economical in all situations.
Air purification, food and beverage production, gas and vapor adsorption, chemical processing, and many other sectors depend on activated carbon. Activated carbon comes in four primary varieties: powdered activated carbon (PAC), granular activated carbon (GAC), pelletized activated carbon (PAC), and honeycomb activated carbon. These are all covered in this article. (HAC). Each type has distinct characteristics, a different manufacturing method, and different applications.
To efficiently accomplish the intended results, it is essential to select the proper type of activated carbon for a particular application. Before choosing the best form of activated carbon, it is important to weigh the benefits and drawbacks of each.
