Activated carbon is a cornerstone of modern purification and adsorption technologies, prized for its versatility and effectiveness. NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive range of activated carbon products, including various mesh sizes and types, to meet diverse industrial demands. This guide aims to clarify the differences between wood-based and coal-based activated carbon and highlight their specific applications.

Activated carbon is categorized by its mesh size, which refers to the fineness of the powder or granules. Common mesh sizes, such as 80, 120, 180, 200, and 325, determine the surface area available for adsorption and the flow rate through filter beds. A finer mesh, like 325 mesh, offers a larger surface area per unit weight, generally leading to faster adsorption rates, which is beneficial for applications requiring rapid impurity removal. For liquid phase applications, smaller mesh sizes are often preferred for maximizing contact time and adsorption efficiency.

When comparing wood-based versus coal-based activated carbon, several key distinctions emerge. Wood-based activated carbon, like the product offered by NINGBO INNO PHARMCHEM CO.,LTD., is derived from renewable resources and is known for its excellent decolorizing attributes and developed mesopores. This makes it particularly suitable for liquid phase applications where color removal and adsorption of larger organic molecules are required. Its high ignition point and relatively low density are also advantageous features. Conversely, coal-based activated carbon often has a more developed micropore structure, making it highly effective for gas phase adsorption and the removal of smaller molecules.

The applications for these different types of activated carbon are extensive. Wood-based activated carbon is widely used in the food and beverage industry for decolorization, in pharmaceuticals for purification, and in advanced sewage treatment. Its strong adsorption performance and renewable source make it an environmentally conscious choice. Coal-based activated carbon, on the other hand, is frequently employed in gas purification, air filtration, and solvent recovery. Both types can serve as catalyst carriers, with the choice depending on the specific catalytic reaction and the nature of the active components to be dispersed.

NINGBO INNO PHARMCHEM CO.,LTD. provides a reliable source for activated carbon powder wholesale needs. Whether you require wood-based activated carbon for its superior decolorizing ability or coal-based for gas phase applications, our product quality is assured, backed by certifications like ISO9001:2015. Understanding the nuances of mesh size and material type, and considering the activated carbon price per kg, allows businesses to make informed decisions for their purification processes, ensuring optimal performance and cost-effectiveness.
