How is columnar activated carbon extruded into strips?

Columnar activated carbon is typically formed from carbonaceous materials like coal, wood, or coconut shells that have been activated to increase their adsorption capacity. This process involves creating a vast network of pores within the carbon structure, significantly increasing its surface area and making it highly effective for filtering and purifying applications. The process of turning this material into extruded strips, often required for specific applications such as water filtration or air purification systems, involves several key steps: 1. **Raw Material Preparation**: The raw carbonaceous material is ground into a fine powder. This increases the surface area available for activation and helps to ensure uniformity in the final product. 2. **Binder Addition**: A binder is mixed with the powdered carbon to help the particles adhere to each other during the extrusion process. Common binders include starch, lignin, or synthetic polymers, depending on the intended use of the activated carb
