What is Pellet Activated Carbon?

Pellets activated carbon is an efficient adsorbent material characterized by its long and slender columnar or cylindrical shape. Compared to other forms of activated carbon, columnar carbon is quick easier to handle, fix, and stack, making it an ideal choice for many gas-phase adsorption applications.

The adsorption principle of pellets activated carbon lies in its unique pore structure. With a wide range of pore sizes, including micropores, mesopores, and macropores, the differences in pore sizes enable columnar activated carbon to adsorb molecules of various sizes and types.

Through physical and chemical adsorption processes, extruded activated carbon can capture and bind liquid or gaseous substances, thereby purifying the environment or treating specific pollutants. This type of activated carbon is widely used in air purification, waste gas treatment, solvent recovery, water treatment, and other fields.

Process of Pellet Activated Carbon

Carbonization

In an oxygen-restricted setting, raw materials like wood, coconut shells, or other organic substances are subjected to heat, enabling the removal of volatile components and the formation of a carbon-rich substance. Carbonization temperatures typically fall between 400 and 600°C, yielding a porous, carbon-laden material known as char.

Methods of activation

Activation develops the internal pore structures and augments the surface area of the carbonized material, thus enhancing adsorption capacity. There are two primary activation techniques:

Physical activation: Here, the carbonized material is heated to high temperatures (800-1000°C) in the presence of an oxidizing gas like steam or carbon dioxide. The reaction between the gas and carbon material generates a porous structure with a vast surface area.
Chemical activation: In this approach, a chemical activating agent, such as phosphoric acid, potassium hydroxide, or zinc chloride, impregnates the carbonized material. The mixture is then heated at lower temperatures (400-800°C) relative to physical activation. A porous structure with a large surface area is created by the chemical reaction between the activating agent and the carbonized material.

Shaping and pelletizing

Activated carbon powder is blended with a binder like starch or molasses to enhance mechanical strength and handling characteristics. This mixture is then fashioned into pellets using methods such as extrusion, pelletizing, or tabletting. The pellet size can be manipulated by adjusting the shaping process parameters.

Post-processing techniques

Depending on the intended application, several post-treatment processes may be employed to improve the performance of the activated carbon pellets. These processes include:

Washing: Pellets can be rinsed with water or a diluted acid solution to remove residual chemicals or impurities from their surfaces.
Drying: To eliminate moisture that could affect adsorption properties, washed pellets are dried at low temperatures (100-150°C).
Activation: In certain cases, a secondary activation step might be needed to further expand the surface area and pore structure of the pellets.

What Is the Alternative to Activated Carbon?

There are several materials that can be used as substitutes for activated carbon and charcoal, depending on the specific application. Some common substitutes include:

Wood vinegar: This is a liquid produced by heating wood to create vinegar. It can be used as a deodorizing agent and can also absorb toxins and impurities.

Bentonite clay: This is a naturally occurring clay that is highly porous and has a strong ability to absorb impurities. It is often used in the production of animal feed and as a natural detoxifying agent.

Peat moss: This is a type of sphagnum moss that is commonly used as a soil amendment. It has a high water-holding capacity and can also absorb impurities.

Fullers earth: This is a type of clay that is often used as a natural absorbent and decolorizing agent.

These materials all work by adsorbing impurities, meaning that they attract and hold onto contaminants through a process of chemical attraction. This can be effective for removing a variety of impurities, including odors, toxins, and excess moisture. However, they may not be as effective as activated carbon or charcoal, which are specifically designed for maximum adsorption efficiency. Additionally, the specific adsorption properties of these materials may differ from those of activated carbon and charcoal.

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.

CPL Activated Carbons operates two separate state-of-the-art reactivation kilns at its site in Immingham, NE Lincs, one dedicated to treating spent carbons from drinking water and food-grade end-users, the other for industrial applications such as wastewater treatment and biogas purification.

The recycling of granular activated carbon in this way not only saves money, but also offers massive environmental benefits, with a CO2 footprint saving in excess of 90% compared with the use of fresh 'virgin' material.
