What are the different types of activated carbon and in which scenarios are they applicable?

1. Wood-based activated carbon: The main raw material is wood, which has excellent adsorption properties and is widely used in water treatment, air purification, food processing, etc.

2. Coal-based activated carbon: Made from coal, it has a high specific surface area and excellent pore structure, and is often used in industrial exhaust gas treatment, gold extraction, etc.

3. Coconut shell activated carbon: Made from coconut shells, it has strong adsorption properties and is suitable for purifying gases and liquids with high purity.

4. Bone charcoal: Made from animal bones, it has a pore structure and is often used in the pharmaceutical and chemical industries.

5. Chemical activated carbon: After chemical treatment, it has specific chemical properties and adsorption performance, and is suitable for the needs of the chemical industry.
