Coal Based Activated Carbon Overview
What is Coal-Based Activated Carbon
You find coal-based activated carbon in many industries because it works as a powerful adsorbent. Manufacturers create this material from high-grade bituminous coal. They heat the coal at temperatures between 600 and 900 degrees Celsius in an oxygen-free environment. This process, called carbonization, removes volatile compounds and leaves behind a char material. Next, they activate the char with steam at even higher temperatures, up to 1100 degrees Celsius. This step forms millions of tiny pores inside the carbon, giving it a huge internal surface area—sometimes up to 1500 square meters per gram.
The structure of coal-based activated carbon includes graphitic plates connected by carbon-carbon bonds. These plates form a network of pores. This network allows the material to attract and trap many types of molecules. You benefit from this unique structure when you need to remove contaminants from water, air, or chemicals. The high carbon content and loss of impurities during production make it especially effective for purification.
Key Properties and Forms
Coal based activated carbon stands out because of its physical and chemical properties. The two-step heating process creates a microporous structure. Micropores help adsorb small molecules, while larger pores allow fluids to reach the adsorption sites quickly. The specific surface area and pore volume determine how much material the carbon can adsorb. Smaller particle sizes, such as 0.15–0.25 mm, offer higher surface areas and pore volumes, making them more effective for many uses.
You can choose from several forms of coal-based activated carbon, depending on your needs:
Powdered Activated Carbon (PAC)
Pellets
Each form works best for different applications. For example, GAC is common in water treatment, while PAC is often used for quick mixing and removal of impurities. Pellets are useful in air purification systems. This versatility makes coal based activated carbon a popular choice for industries that require reliable purification solutions.
