Custom Sizes Diameter 1.5-4.0mm, tailored to your reactor design 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...

How to select high-quality coal-based activated carbon？

Characteristics of coal-based activated carbon Get Free Quote Coal-based activated carbon is made from coal through carbonization and activation. Its main characteristics include: 1. High specific surface area: It has a rich microporous structure and provides a large number of adsorption sites. Good mechanical strength: It is wear-resistant and not easy to break, suitable for various filtration and adsorption devices. Chemical stability: It remains stable in acid, alkali and high temperature environments and is not easily destroyed by chemical reactions.Methods for selecting high-quality coal-based activated carbon Specific surface area Specific surface area is an important indicator for measuring the adsorption capacity of activated carbon. Generally speaking, the larger the specific surface area, the stronger the adsorption capacity of activated carbon. The commonly used measurement method is the BET (Brunauer-Emmett-Teller) method. Pore size distribution The pore size distribution of coal-based activated carbon has an important influence on its adsorption performance. According to the application requirements, select activated carbon with appropriate pore size distribution. For example, activated carbon used for water treatment should have more mesopores and macropores to effectively remove large molecular organic matter; while activated carbon used for gas adsorption requires more micropores to improve the adsorption capacity of small...
