ActiveTest method for granular activated carbon from coal - Determination of hardness
煤质颗粒活性炭试验方法 强度的测定
Application Summary AI generated
This standard specifies the method for determining the mechanical hardness of coal-based granular activated carbon. It is applied in the quality control and testing of activated carbon used in industrial processes such as water treatment, gas purification, and solvent recovery, where resistance to attrition during handling and regeneration is critical. The test ensures the material meets durability requirements for long-term use in fixed or moving bed adsorption systems.
