Coal-based granular activated carbon (GAC) is a material produced from coal that has undergone a process of activation, creating a high surface area with numerous pores. This material is widely used for various applications, including water treatment, air purification, and other industrial processes.
Production and Properties:
Raw Material:
GAC is typically made from coal, but other carbon-rich materials like wood and coconut shells can also be used.
Activation Process:
The coal is heated to a high temperature (800-1000°C) under controlled conditions, often using steam or other oxidizing gases, to develop its porous structure.
Porous Structure:
The activation process creates a network of pores on the surface of the carbon granules, significantly increasing their surface area and adsorptive capacity.
Applications:
Water Treatment:
GAC is used in water treatment to remove contaminants, such as organic compounds, chlorine, disinfection byproducts, and taste/odor compounds.
Air Purification:
It can be used in air filters to remove harmful gases and particulate matter from air, for example, in industrial settings or in gas masks and respirators.
Other Industrial Uses:
GAC finds applications in food and beverage processing, metal recovery, medical and pharmaceutical industries, and chemical purification.
Advantages:
High Surface Area:
The porous structure of GAC provides a large surface area for adsorption, making it effective at removing various pollutants.
Adsorption Capacity:
It can adsorb a wide range of contaminants, including organic compounds, gases, and heavy metals.
Reusable:
GAC can be regenerated and reused, making it an environmentally friendly option.
