Understanding the Differences Between Activated Carbon and Virgin Activated Carbon

Activated carbon, also known as activated charcoal, is a porous material that has been processed to increase its adsorption capabilities. It plays a critical role in various applications such as water and air purification, chemical processing, and even medical treatments. Virgin activated carbon, on the other hand, is a specific type of activated carbon that has not been previously used or regenerated. Both materials share similarities but also have distinct differences that are significant in their respective applications.

Definition of Activated Carbon

Activated carbon is a highly porous material derived from carbonaceous sources such as coal, wood, or coconut shells. It is produced through a process of activation that increases its surface area and porosity, making it an excellent material for the adsorption of impurities and contaminants from both gases and liquids.

Definition of Virgin Activated Carbon

Virgin activated carbon, specifically, refers to activated carbon that has not been used or regenerated. It is a new form of activated carbon that has not been exposed to contaminants or chemical processes that could alter its properties. This makes it essential for applications requiring high purity, such as in food and beverage processing, pharmaceuticals, and certain environmental applications.

Key Differences

State

The primary difference between activated carbon and virgin activated carbon lies in their usage state. Virgin activated carbon is unused and pure, whereas activated carbon can refer to any form of activated carbon, including used or regenerated materials.

Purity

Virgin activated carbon is free from contaminants. In contrast, used activated carbon may contain adsorbed substances from previous applications, reducing its effectiveness. Regeneration, a process aimed at restoring the adsorptive capacity of activated carbon, is not applicable to virgin activated carbon.

Regeneration

Activated carbon can undergo the regeneration process to remove previously adsorbed impurities and restore its adsorptive properties. However, virgin activated carbon is never subjected to this process because it is brand new and unaltered.

Raw Materials and Forms

Activated carbon can be made from a variety of raw materials, including sawdust, hardwood chips, wood charcoal, peat, coconut shells, lignite, brown coal, bituminous coal, and anthracite coal. Vulcanized carbon and phenolic resin are also used sometimes. Virgin activated carbon, however, is typically made from coconut shells or wood charcoal and undergoes steam-based activation to enhance its porosity and surface area.

Virgin activated carbon is often available in granular or pellet form, which makes it highly effective for the removal of low molecular weight contaminants. It is notably used in specific applications such as gas-phase applications and speciality applications like gold refining. Normal activated carbon can be found in various forms, including powder, granules, pellets, and custom-made sizes.

Advantages of Virgin Activated Carbon

Virgin activated carbon offers several advantages over normal activated carbon:

High absorptivity Low ash content Hardness and abrasion in specific areas compared to regular activated carbon Higher density than regular carbon Low attrition loss Low dust content

Suitability for Different Industries

Both activated carbon and virgin activated carbon are widely used in various industries. Activated carbon is used in water treatment plants, medicine, air purification, and other applications. Virgin activated carbon, however, has specific uses in gas-phase applications and specialty applications like gold refining.
