How to choose the right activated carbon

Activated carbon is a type of carbon processed to form a huge micropore network. This unique structure gives it an extremely high surface area, allowing it to effectively adsorb impurities and contaminants. There are many types of activated carbon, including granular, powdered and extruded, each of which is suitable for different application processes.

Factors to consider when choosing activated carbon:

1. Application areas

  • Air purification: Coconut shell activated carbon with developed micropores is preferred, and the CTC value and benzene adsorption rate are paid attention to.

  • Water treatment: Choose coal or wood activated carbon with more mesoporous pores, and pay attention to iodine absorption and methylene blue value.

  • Food and Medicine: It must meet food-grade standards (such as FDA certification), and choose high-purity wood or coconut shell activated carbon.

  • Industrial catalysis or gas separation: custom pore size distribution and surface chemistry (such as impregnation of activated carbon).

2. Adsorption capacity

The adsorption capacity of activated carbon refers to its ability to capture pollutants. Adsorption capacity is affected by material type, surface area, and pore structure. When choosing activated carbon, please consider the following points:

  • Surface area: Usually a larger surface area will lead to better adsorption capacity.

  • Pore size distribution: Different pollutants are adsorbed in different pore sizes. Ensure activated carbon has a pore structure suitable for your specific application.

3. Chemical compatibility

Different types of activated carbon have different chemical affinities. Do an in-depth study of the contaminants you want to remove. For example, if you are dealing with chlorinated compounds, some types of activated carbon may be more effective than others. Make sure to choose a product that is compatible with your specific contaminants.

4. Regeneration and reusability

Some activated carbon products can be recycled and reused, while others are used for single use. If cost-effectiveness and sustainability are considered, consider products that are easy to regenerate. Research the methods you can use for regeneration and determine if they are suitable for your business.

5. Quality and certification

Quality is important when choosing activated carbon. Look for products certified by well-known organizations, such as NSF (National Health Foundation) or AMS (National Standards Association). This ensures that activated carbon meets specific performance and safety standards.

6. Package and dimensions

Activated carbon comes in many forms, including particles, particles and powders. Your choice depends on your application requirements:

  • Granular activated carbon (GAC): Very suitable for large systems and long-term use.

  • Powder activated carbon (PAC): suitable for applications requiring rapid absorption.

  • Extruded activated carbon: Usually used in environments where low pressure drop and high flow rates are required.
