AGICO provides customers with tailor-made coconut shell activated carbon production solutions. FREE CONSULTATION, don’t hesitate to tell us your need!

Coconut shell is the hard inner shell that houses the coconut kernel. It comes as a by-product of coconut meat and coconut milk processing and is often considered agricultural waste. While coconut shells actually have many other uses, not least in the production of activated carbon. Compared with bamboo, wood, oil palm, and other raw materials, the activated carbon produced by it has higher adsorption capacity and efficiency.

High Safety & Non-toxic

Among all types of activated carbon, only coconut shell activated carbon and fruit shell activated carbon are suitable for drinking water purification. They are odorless, tasteless, and non-toxic, which is the best choice for industries with high safety requirements such as food and edible oil.

Excellent Adsorption & Long Service Life

Compared with other activated carbons, coconut shell activated carbon has the most developed pore structure and high iodine value. Therefore, it has strong wear-resistant and adsorption performance, which can absorb more substances and prolong the service life (2-3 years).

Environmentally Friendly

The raw material of coconut shell activated carbon is renewable. Coconut trees absorb carbon from the atmosphere and then produce oxygen. Coconut shells contain these carbons and are processed into activated carbon. This is a natural way of reusing natural resources.

Why choose to invest in coconut shell activated carbon manufacturing?

Easy Obtained Raw Material: the coconut tree is grown in more than 80 countries, such as Indonesia, Philippines, India, Sri Lanka, and other Southeast Asian and Pacific countries. The coconut is available throughout the year, grows with large output, and the coconut shell is easy to store.

Immense Markets: coconut shell activated carbon is in great demand in the market. It is available in many fields, such as drinking water purification, sewage purification, food production, pharmaceutical preparation, flue gas purification, etc. The vast market guarantees sales volume and huge profits.

Mature Production Technology: whether it is chemical activation or physical activation, the production process of coconut shell activated carbon is very mature. The modern activated carbon production line can achieve high output and high automation while ensuring product quality.

Coconut Shell Activated Carbon Manufacturing Process

The production method of coconut shell activated carbon can be divided into chemical activation methods and physical activation methods.

Chemical activation is a series of crosslinking or polycondensation reactions between chemical reagents and coconut shell carbonized materials so that the carbonized materials have a rich microporous structure.

Physical activation is to use air, carbon dioxide, water vapor, and other oxidizing gases to react with carbon atoms in the coconut shell carbonized material at high temperatures so that the carbonized material has a rich microporous structure.

The production time of the chemical activation method is short and the required temperature is low. However, the use of a large amount of chemical reagents increases the production cost and has a strong corrosion effect on the equipment, especially in the later stage, a large amount of water is required for washing. These wastewaters can only meet the environmental protection discharge requirements after complex treatment processes. It is for this reason that many people choose to use the physical activation method to produce activated carbon because the process is simple and clean, but the energy consumption is slightly higher.

* The activation method in the following production process is physical activation.

Step1: Raw Material Preparation

As raw material, large quantities of coconut shells need to be cleaned first to remove dust and impurities on the surface and then dried, crushed, and screened to obtain prepared coconut shell fragments of moderate size. Next, they are sent to the carbonization furnace.

Step2: Raw Material Carbonization

The coconut shell carbonization is mainly completed in the carbonization furnace. Under high temperatures (150-650°C), coconut shell undergoes a series of physical changes (dehydration and degassing, such as CO, CO2, H2S, etc.) and chemical changes (polycondensation and pyrolysis) to finally form a carbonized material with a primary pore structure.

Step3: Carbon Activation

The carbonized coconut shell is activated in an activation furnace. Under high temperatures (800-1050°C), the water vapor, carbon dioxide, or air are taken as activating gases to oxidize the carbonized coconut shell for further enlarging the original pores in the body, create new pores, and remove tar and other substances.

Step 4: Washing & Drying

The washing and drying is an optional process. It aims to remove impurities and heavy metals inside the activated carbon. The washing process includes acid washing and water washing which is carried out in the washing tank.

Step 5: Grinding & Screening

According to different application directions, coconut shell activated carbon often needs to be ground to different particle sizes. Therefore, we use grinding equipment and screening equipment to help complete this process.

Step 6: Packaging

After grinding, we will use a packing machine to pack the coconut shell activated carbon into bags, usually 25kg/bag. Then they will be loaded into trucks or stored in warehouses.
