For procurement managers and R&D scientists in the B2B chemical and pharmaceutical sectors, selecting the correct activated carbon is crucial for optimizing process efficiency, ensuring product quality, and managing costs. With a multitude of types, sizes, and specifications available, understanding the key characteristics is essential. As a prominent activated carbon manufacturer and supplier, we aim to demystify the selection process for industrial-grade activated carbon, focusing on our high-quality coal-based granular activated carbon.

The primary function of activated carbon is adsorption, which is heavily dependent on its physical structure. Two critical parameters to consider are the specific surface area and the pore structure. A larger specific surface area, typically measured in m²/g, generally equates to higher adsorption capacity. For instance, our coal-based granular activated carbon boasts a specific surface area of around 950 m²/g, making it highly effective for a broad range of applications.

Key Selection Criteria for Industrial Activated Carbon:

  • Material Source: Coal-based activated carbon, like ours, is renowned for its hardness, abrasion resistance, and developed pore structure, making it ideal for gas-phase applications and water treatment. Other sources include coconut shells and wood, each with unique properties.
  • Form: Activated carbon is available in granular, powdered, and pelletized forms. Granular activated carbon (GAC) is most common for fixed-bed adsorbers in continuous processes, offering ease of handling and regeneration.
  • Adsorption Capacity: Key indicators include Iodine Adsorption Value (IAV) and Carbon Tetrachloride (CTC) adsorption. Higher IAV (e.g., 600-1100 Mg/G for our product) signifies better adsorption of small molecules, while CTC adsorption indicates effectiveness with larger molecules.
  • Mechanical Strength: For industrial applications, especially in dynamic systems, activated carbon must resist attrition. Our coal-based GAC offers high strength (>96%), ensuring longevity and reduced fines generation.
  • Pore Size Distribution: The distribution of micropores, mesopores, and macropores determines which contaminants the carbon will effectively adsorb. A balanced distribution is often preferred for versatile applications.
  • Ash Content and pH: Lower ash content (typically <10% for our product) and a neutral pH are generally desirable for most purification processes to avoid introducing unwanted elements into the treated medium.
