Activated Carbon: An Overview, Classification
Introduction to Activated Carbon
Activated carbon, also known as activated charcoal, is a highly porous material renowned for its exceptional adsorption properties. It is produced from carbon-rich raw materials such as wood, coconut shells, coal, and peat through a process called activation. This process involves carbonizing the raw material at high temperatures in the absence of oxygen, followed by treatment with steam or chemicals to create a vast network of pores. These pores significantly increase the material's surface area, enabling it to effectively trap and remove impurities, contaminants, and pollutants.
Due to its versatility and efficiency, activated carbon is widely used across various industries, including water and air purification, food and beverage processing, pharmaceuticals, and environmental remediation. Its ability to adsorb a wide range of substances makes it an indispensable tool for improving quality and safety in numerous applications.
Classification of Activated Carbon
Activated carbon can be categorized based on its physical form, raw material, and activation method. Below are the primary classifications:
Based on Physical Form:
Powdered Activated Carbon (PAC): PAC consists of fine particles, typically smaller than 0.18 mm. It is commonly used in liquid-phase applications, such as water treatment, due to its high adsorption capacity and rapid action.
Granular Activated Carbon (GAC): GAC comprises larger particles, usually ranging from 0.2 to 5 mm. It is ideal for use in fixed-bed filters for water and gas purification.
Pelletized Activated Carbon: This form is compressed into cylindrical pellets, making it suitable for applications requiring low pressure drop and high mechanical strength, such as air purification systems.
Activated Carbon Fiber (ACF): ACF is a textile-like material made from carbon fibers. It offers a high surface area and is used in specialized applications, including gas masks and solvent recovery.
Based on Raw Material:
Wood-Based Activated Carbon: Derived from wood, this type is often used in applications requiring high purity, such as in the food and pharmaceutical industries.
Coconut Shell-Based Activated Carbon: Known for its high microporosity, this type is ideal for water purification and gold purification.
Coal-Based Activated Carbon: This type is widely used in industrial applications due to its cost-effectiveness and availability.
Based on Activation Method:
Physical Activation: This method involves carbonizing the raw material followed by activation using steam or carbon dioxide at high temperatures.
Chemical Activation: In this method, the raw material is impregnated with chemicals such as phosphoric acid before carbonization, resulting in a highly porous structure.
