What is Pellet Activated Carbon

Granular activated carbon, often abbreviated as GAC, is a high-purity carbon characterized by a large surface area that can be used in many liquid and gas phase purification applications. Particles typically range in size from around 0.2 mm to 5 mm, and the choice of "mesh size" depends on the desired end use of the material. Particles smaller than 0.2 mm are generally classified as powdered activated carbon (or PAC).

How is Pellet Activated Carbon Manufacturing

Raw Material Grinding
The first step involves grinding the raw material coal to a certain fineness (generally above 95% passing through 180 mesh). Raw materials suitable for production include anthracite, coconut shell powder, wood, etc. The commonly used material is taixi coal from Ningxia.

Binder Formulation
After preparing the raw materials, a certain amount of binder (commonly tar) and water are added. When using the catalytic activation method, a certain amount of catalyst is simultaneously added at a certain temperature for a specified duration. The treated hard coal is mixed with a certain proportion of tar, ensuring uniformity for molding.

Granulation or Molding
Once the added binder and water fully infiltrate, permeate, and disperse evenly with the coal powder, the mixture is pressed into charcoal rods using a molding machine under a specific pressure and with a certain diameter extrusion die. The formed columnar charcoal is then dried under specific conditions to maintain a specific moisture content, usually around 10%, to form a robust charcoal structure.

Carbonization
The dried charcoal is placed in a carbonization furnace, and slowly heated to control the carbonization speed and temperature, reaching the conditions for chemical reactions. This process causes the gradual thermal decomposition and volatilization of organic substances in the charcoal, forming a structure with numerous pores and high carbon concentration.

Activation
After carbonization, the raw material undergoes activation to increase its pore structure and surface area. Activation develops more micropores and mesoporous structures, enhancing the adsorption capacity of activated carbon.

Further Processing (Optional)
Activated carbon pellets may undergo additional treatments such as acid washing or impregnation according to market demands. For example, adding catalysts or special substances to enhance specific application effects. Detailed explanations can be found in this article.
Quality Inspection and PackagingThe produced pelletized activated carbon undergoes quality inspection to ensure compliance with relevant standards and quality requirements. After rigorous inspection, it can be packaged in custom-branded bags or other weight bags for customer use.

How does Granular Activated Carbon Work

The surface of granular activated carbon is made up of microscopic holes and channels, known as pores, only visible under a suitably powerful microscope. It is these pores that result in its huge surface area – the statistic often quoted is that a teaspoon of granular activated carbon has the same surface area as a football pitch!

When a contaminated fluid passes through a filtration device containing granular activated carbon, the impurities are trapped within these pores in a process called adsorption, allowing the purified fluid to pass through. Typical applications for granular activated carbon include the removal of taste, odour and colour from drinking water, as well as traces of other dissolved contaminants such as pesticides and herbicides.

One of the key advantages with using granular activated carbon for fluid purification, rather than powder activated carbon, is that granular activated carbon can be recycled for reuse via a process called thermal reactivation. Carbon that is spent, ie the pores are filled with contaminants so that the treatment objective is no longer being achieved, can be passed through a high temperature kiln. The contaminant molecules are forced out of the pores and destroyed, leaving a reactivated granular activated carbon ready to be used again and again in the customer's process.

Types of Activated Carbon

Granulated Activated Carbon
Granulated activated carbon has a smaller external surface than powdered activated carbon as a result of its slightly larger particle size. This type is mostly utilized in general deodorization, air treatment, and water treatment.

Pelletized Activated Carbon
This is powdered activated carbon that has been mixed with a binder and formed into pellets. The pellets are typically employed in gas phase applications because they have a low dust content, good mechanical strength, and a low-pressure drop.

Powdered Activated Carbon
This is a fine form of activated carbon, and it is typically added directly to process units like raw water intakes, gravity filters, and clarifiers. Due to the probable head loss that might happen, it is rarely utilized in a dedicated vessel.

Impregnated Activated Carbon
This form of activated carbon is infused with inorganic impregnates like silver and iodine. The biggest application for impregnated activated carbon is in the purification of domestic potable water.

Catalytic Activated Carbon
This fifth type of activated carbon is also called surface-modified activated carbon. In addition to being adsorptive, it may also initiate and enhance chemical processes, which makes it useful for removing contaminants from drinking water.

Benefits of Activated Carbon in Water Treatment

This makes it effective and affordable to use, qualities that any water purification plant would be interested in for the sake of its overheads and the quality of production.

Reliable and efficient:Activated carbon is incredibly reliable and efficient. As long as all relevant aspects are taken into consideration, there is very little danger of failure when the appropriate form is utilized. It is a tried and tested solution that has improved over time to become the standard method in the water purification sector.

How to Make Activated Carbon Pellets

The production of activated carbon granules involves several key steps. First, the carbonaceous material is carbonized at high temperatures in the absence of oxygen, removing the volatile compounds and leaving behind a carbon-rich material. The carbonized material then undergoes an activation process. Activation is achieved by exposing the carbonized material to high temperatures (800-1000°C or 1472-1832°F) and an activating agent such as steam or carbon dioxide. This process creates a vast network of pores that enhance the material's surface area and adsorption capacity. The active material is then processed into pellets or granules to form activated carbon pellets.
