What Is The Process Of Carbonization Of Coconut Shells?

In today’s world, people are placing more and more emphasis on health and quality of life. Indoor air purification is an important need for homes and offices. Coconut shell activated carbon is a product often used in our life. It is a very used adsorbent and catalyst carrier. It is a kind of high efficient adsorption material made from natural coconut shell through responsible process. Therefore, it is widely used in air purification, water treatment, medicine and other industries. Today we will introduce the production process and carbonisation process of coconut shell activated carbon in detail.

What Is The Process Of Carbonization Of Coconut Shells?

Carbonisation process of coconut shell

Raw material selection: first select high-quality raw materials is the key to the production of coconut shell activated carbon. Coconut shell is mainly from: Hainan coconut shell and Indonesia coconut shell. It has high density and high hardness. It is more suitable for producing high quality activated carbon.

Drying: The selected high quality coconut shells are dried. It can reduce the moisture in the raw material. This will facilitate the subsequent processing.

Material cleaning: Make sure the surface of coconut shell is free of any impurities and adherents. This step is also the key to ensure the quality of activated carbon.

Crushing: After drying, the coconut shells are crushed into small particles. It is convenient for the subsequent carbonisation process. This step requires professional crushing equipment.

Carbonisation of materials: the crushed coconut shells are carbonised at high temperature in the coconut shell carbonisation furnace. In the process of carbonisation, organic matter is decomposed under high temperature and oxygen-poor atmosphere. This produces high quality coir carbon. The temperature of the carbonisation process is usually controlled between 500℃ and 800℃. Depending on the material, the carbonisation time and temperature should be precisely controlled. The carbonisation process should be completed completely.

Coconut shell carbon activation: This step is the key to increase the porosity and specific surface area of activated carbon. Common methods are: physical and chemical. Physical activation uses high temperature steam and gas combustion to expand the pore structure of the carbon surface. Chemical activation increases the porosity through the use of alkaline metal hydroxides or acids.

Acid washing and rinsing: This step is designed to remove impurities. After activation, the activated carbon is subjected to an acid washing and rinsing process.

Finish product cleaning: Activated carbon is thoroughly cleaned in this step. Ensure its purity.

Drying treatment: the cleaned activated carbon is dried again. It is convenient for subsequent packaging and transport.

Sieving and sorting: the dried activated carbon will be sieved through vibrating screen according to different particle size requirements of customers. Common particle size: 6-12 mesh, 8-16 mesh, 10-24 mesh, 20-40 mesh and other four specifications.

Finished product packaging: double-layer plastic woven bag or tonne bag. With moisture-proof and other functions.

Storage and transport: The finished coconut shell activated carbon should be stored in dry and ventilated place. Avoid direct sunlight or humid environment. In the process of transport, it needs to be held gently and put down lightly. Prevent the packaging damage caused by the product moisture.

To sum up: the production process of coconut shell activated carbon. Each environment needs to be strictly controlled. Ensure the high quality of the final product. The production of coconut shell activated carbon requires the use of coconut shell carbonisation furnace. Coconut shell activated carbon has excellent adsorption properties and a wide range of application prospects. It makes an important contribution in many industrial fields.
