COCONUT SHELL ACTIVATED CARBON SOLUTION

Ready to make money with coconut shells?

Do you want to make money with activated carbon from coconut shells? This is the right way to get a full and useful solution for coconut shell activated charcoal production. As a professional activated carbon plant solution provider, we analyze finished products – coconut shell-based activated carbon first, there are four questions we will ask before starting the coconut shell activated carbon business:

1. What is coconut shell based activated charcoal?

Coconut shell based activated carbon is made of high-quality coconut shells and refined through a series of production processes. coconut shell based activated carbon is black in appearance and has two types granular and columnar. It has the advantages of developed pores, good adsorption performance, high strength, easy regeneration, economics, and durability.

2. Why do we start a coconut shell activated carbon plant business?

Based on all these advantages we mentioned above, coconut shell based activated carbon is widely used in metallurgy, chemical industry, petroleum, electric power, food, drinking water, pure water, beverage, industrial water deep purification, and precious metal refining liquor to reduce the degree of turbidity, and zeolite, a molecular sieve with a better effect, is well received by users.

Why is the coconut shell activated carbon business so hot? Coconut shell based activated carbon is currently the main product of deep processing of coconut shells. Coconut shells are fired into coconut shell charcoal and further activated to make coconut shell based activated carbon. 1 ton of coconut shell can process about 300 kg of coconut shell charcoal, and can further extract about 120 kg of coconut shell activated carbon. coconut shell activated carbon plant is a good way to turn biomass into money and protect our environment.

3. What we can produce with coconut shell activated carbon plant?

At present, there are four main types of coconut shell activated carbon we can produce, including granular activated carbon, columnar activated carbon, powdered activated carbon, and honeycomb activated carbon.

The finished product – coconut shell based activated carbon

4. How to produce coconut shell activated carbon?

To be clear, we list the basic 6 steps of the coconut shell activated carbon production line for reference, all sections of the activated carbon plant can be customized by the engineering team.

Coconut shell activated carbon manufacturing process

There are several types of processes to make activated charcoal from coconut shells, Today we take the physical activation method as an example.

Note: The physical activation method refers to one of the methods of producing activated carbon under high-temperature conditions using air-steam mixed gas, water vapor, or other gas as the activator and using a special furnace type. Activated carbon produced by this method has the advantages of developed pore structure, huge specific surface area, strong adsorption performance, high mechanical strength, small fluid resistance, stable chemical properties, high purity, and easy regeneration.

Step1: Preparation of raw materials

Firstly, we do a selection of the coconut shell. There are two main sources of raw materials for coconut shell activated carbon on the market, one is Hainan coconut shell and the other is Indonesian coconut shell. Hainan coconut shells are thin and not very dense, while Indonesian coconut shells are thicker and denser. In contrast, the quality of activated carbon processed from Indonesian coconut shells will be better. After the selection of raw materials, pre-treat coconut shell through some sections such as drying, crushing and screening before going to next step.


Activated Carbon Rotary Kiln
Step2: carbonization

Secondly, one of the key processes –carbonization process begins. Put the screened coconut shells into the carbonization equipment, dry the raw materials at a temperature of 170-600 °C, and carbonize 80% of the organic tissue in the same amount. After burning to a certain extent at high temperature, the charcoal kiln is closed to allow air to enter, and then the residual heat continues to heat and dry distillation, so that the moisture and wood tar in the coconut shell are leached out, and the coconut shell activated carbon is formed. 


Activation kiln
Step3: activation

Thirdly, put carbonized coconut shell into activated rotary kiln, Oxygen-containing gases as water vapor and flue gas (mainly CO2) are used as activators, and activated by redox reaction in contact with carbon at high temperature. The main operating conditions of the activation process include activation temperature, activation time, flow rate and temperature of the activator, feeding speed, oxygen content in the activation furnace, and etc.


Step4: Grinding and screening

Fourthly, after activation, the finished coconut shell activated carbon is made. Sometimes, the client may have a specific requirement in size, and then we need to send coconut shell activated carbon to the grinding mill (Raymond mill). The finished activated carbon is screened according to the customer’s particle size requirements. The common coconut shell activated carbon particle sizes are 6-12 mesh, 8-16 mesh, 10-24 mesh, 20-40 mesh, 200 meshes, 325 meshes, and so on.


Step5: Pickling, washing and drying (optional step)

This is an optional step for coconut shell activated carbon production, according to the technical requirement, part of the finished activated carbon needs pickling to remove impurities. 5% hydrochloric acid can be used as pickling agent in a dedicated pickling tank. After heating and boiling. Then drain the spent acid. The washing process is used for removal of acid of materials, PH value is generally controlled to 5-7. Washed materials must be dried until the moister content reaches 10%(or the value is decided by clients.)


Step6:Packing

Finally, the packaging specification of coconut shell activated carbon is generally 25kg/bag or ton bag, and the packaging bag adopts double-layer woven bag, which is strong and has moisture-proof function.

One thing to be clear, this is an example process for coconut shell activated carbon making, we can provide customization service according clients’ real working condition and requirements.

Coconut shell based activated carbon market analytics

For new beginners, one of your considerations will be development potential of coconut shell activated carbon.

At present, there are mainly five countries in the world that produce coconut shell activated carbon, the proportions are the Philippines, Sri Lanka, Indonesia, Malaysia and Thailand, mainly because these countries have a large area of ​​coconut trees and are rich in coconut shell resources. The export volume of coconut shell activated carbon from these five countries accounts for more than 70% of the global coconut shell activated carbon export scale, and the export volume continue to increase at a growth rate of about 4% every year.

Judging from the overall development trend of the activated carbon market at this stage, the global coconut shell activated carbon market demand will continue to rise in the future, and the domestic coconut shell activated carbon market scale will also maintain a stable growth trend. On the one hand, environmental pollution has become a global problem, activated carbon is being used more and more in the fields of air purification and water purification; on the other hand, although china’s economic development has entered a new track and economic growth has slowed down, The overall development scale of the industrial industry is still expanding, and the demand for activated carbon is also expanding. At the same time, the application demand of coal-based carbon has shown a downward trend due to resource and environmental protection issues, and the market demand for coconut shell activated carbon and fruit shell activated carbon has continued to rise.
