How to choose suitable activated carbon to meet industrial needs

Choosing the appropriate activated carbon to meet industrial demand is a complex process that requires consideration of multiple factors. Here are some key steps and considerations:

Clear application requirements:

Determine which industrial processes activated carbon will be used for (such as water treatment, air purification, refining of chemical products, etc.).

Identify specific pollutants that need to be removed or adsorbed (such as organic matter, heavy metals, pigments, odors, etc.).

Types of activated carbon:

Raw material source: Activated carbon can be made from different raw materials such as wood, coal, fruit shells, bamboo, etc. The performance of activated carbon varies depending on the raw material.

Shape and size: Activated carbon can be in powder, granular, columnar, etc. Different shapes of activated carbon are suitable for different process flows.

Physical and chemical properties:

Specific surface area: The larger the specific surface area, the stronger the adsorption capacity of activated carbon.

Pore structure: The ratio of micropores, mesopores, and macropores affects the adsorption characteristics and application fields of activated carbon.

Iodine value: Iodine value is an indicator of the adsorption capacity of activated carbon. Generally, the higher the iodine value, the stronger the adsorption capacity.

Ash content: Ash content affects the chemical purity of activated carbon, and the lower the ash content, the higher the purity of activated carbon.

PH value: Select activated carbon within the corresponding pH range based on the pH value of the application medium.

Operating conditions:

Temperature: Consider the stability and adsorption efficiency of activated carbon at a specific temperature.

Flow rate: The particle size and bed height of activated carbon will affect the flow rate of fluid in the activated carbon bed.

Contact time: Ensure sufficient contact time between pollutants and activated carbon to achieve effective adsorption.

Economy:

Consider the purchase cost, service life, regeneration cost, and replacement frequency of activated carbon.

Supplier and Product Quality:

Choose reputable suppliers to ensure stable product quality.

Review the supplier's product specifications and conduct sample testing.

Regulations and standards:

Ensure that the selected activated carbon complies with relevant industrial standards and environmental regulations.

By following the above steps, it is possible to more accurately select activated carbon that is suitable for specific industrial needs. It is recommended to conduct small-scale experiments before practical application to verify whether the performance of activated carbon meets expectations.
