Coconut Shell Activated Carbon

Production: Coconut shells are first carbonized to create charcoal. This charcoal is then "activated" through a process that involves heating it to high temperatures in the presence of gases like steam or carbon dioxide. This activation process creates a network of pores and increases the surface area of the material.

Pore Structure: Coconut GAC typically has a well-developed pore structure, consisting of both micro-pores and meso-pores. These pores vary in size and help the activated carbon adsorb a wide range of molecules.

Applications: Coconut granular activated carbon finds applications in various industries, including water treatment, air purification, food and beverage processing, pharmaceuticals, gold recovery in mining, and more. It is commonly used to remove impurities, contaminants, odors, and unwanted compounds from liquids and gases.

Water Treatment: In water treatment, coconut GAC is used to remove organic compounds, chlorine, taste, odor, and certain heavy metals from water. It is employed in both municipal water treatment plants and household water filtration systems.

Air Purification: Coconut GAC is used in air purifiers and industrial air treatment systems to capture volatile organic compounds (VOCs), gases, and odors from the air.

Gold Recovery: In mining, activated carbon, including coconut GAC, is used to adsorb gold cyanide complexes in the process of gold recovery from ore solutions.

Food and Beverage: Coconut GAC is used in the food and beverage industry for decolorizing, purifying, and deodorizing various products, such as sugar, edible oils, and alcoholic beverages.

Renewable Source: Using coconut shells as a raw material for activated carbon production is considered more sustainable than other sources since coconut shells are a byproduct of the coconut industry.

Production: The production process of coconut pellet activated carbon is similar to that of other activated carbons. It involves carbonizing coconut shells to create charcoal and then activating the charcoal through a high-temperature process in the presence of steam or other activating agents. The activated material is then ground into a fine powder and shaped into pellets under pressure.

Uniformity: Pelletized activated carbon offers greater uniformity in terms of particle size and shape compared to granular or powdered forms. This uniformity can provide more consistent adsorption performance.

Lower Pressure Drop: In applications where activated carbon beds are used, such as gas or liquid phase adsorption systems, pelletized activated carbon can result in lower pressure drops. This can be advantageous in maintaining optimal flow rates and minimizing the need for frequent replacement.

Reduced Dusting: Pelletized activated carbon produces less dust and fines compared to powdered activated carbon. This is particularly important in applications where dust generation could be problematic.

Handling and Storage: Pellets are easier to handle, transport, and store than loose granules or powders. Their cylindrical shape allows for efficient packing and reduces the risk of dust release during handling.

Applications: Coconut pellet activated carbon finds applications in various industries, including water treatment, air purification, gas phase filtration, and more. Its use is similar to other forms of activated carbon and depends on the specific requirements of the application.

Regeneration: Like other forms of activated carbon, coconut pellet activated carbon can be regenerated and reused after it becomes saturated with adsorbed compounds. Regeneration involves heating the carbon to release the adsorbed substances, restoring its adsorption capacity.

Sustainability: Using coconut shells as a raw material for pelletized activated carbon aligns with sustainability goals, as coconut shells are a renewable resource.
