NINGBO INNO PHARMCHEM CO.,LTD. provides a comprehensive range of coal-based activated carbon products, emphasizing the critical importance of material properties in achieving optimal purification and catalytic performance. Understanding these characteristics is key to selecting the right activated carbon for any given application, whether it’s for water treatment, gas purification, or as a catalyst carrier.

The most significant property of activated carbon is its extraordinarily large surface area, typically exceeding 1000 m²/g. This vast surface area, created through a carefully controlled activation process, is what enables its exceptional adsorptive capabilities. Contaminants in water or gases adhere to these surfaces, effectively removing them from the treated medium. This principle is fundamental to water purification and gas purification.

Equally important is the pore structure – the distribution and size of the pores within the activated carbon matrix. Different contaminants have different molecular sizes, and selecting activated carbon with appropriate pore sizes ensures maximum adsorption efficiency. For instance, smaller molecules might be best captured by carbons with micropores, while larger molecules may require mesopores. This is why understanding activated carbon for water treatment involves considering the specific impurities to be removed.

The physical characteristics of activated carbon, such as hardness and density, also play a crucial role in its application. High hardness (e.g., 95% in our products) ensures that the activated carbon granules resist attrition and breakage, especially in packed beds or during backwashing in industrial systems. This durability translates to a longer service life and reduced fines production, which is critical for maintaining system efficiency. Apparent density (400-680 kg/M³) and filling density (0.38-0.58 g/cm³) are important for vessel design and capacity calculations.

For applications in catalysis, the surface chemistry of activated carbon can be tailored. As a catalyst carrier, the surface can be modified to enhance the binding of catalytic species or to introduce specific chemical functionalities. The high CTC (Carbon Tetrachloride) value (40%-85%) often indicates a high adsorption capacity for organic molecules, which is beneficial in many chemical processes and gas phase applications.
