How To Make Activated Coconut Shell Charcoal

Coconut shell activated carbon is often used as an adsorbent. It is widely used in: sewage treatment, air purification, chemical industry, metallurgy, food processing, medicine and other industries. However, its production process is complicated and each step is crucial. We will introduce the production process of coconut shell activated carbon.

1. Preparation of raw materials: the main raw material of coconut shell activated carbon is coconut shell. Coconut shell is rich in cellulose and hemicellulose. It is often used as an ideal raw material for making coconut shell activated carbon. When selecting coconut shells, we should pay attention to the following: freshness, no pests and diseases, no impurities and so on. After the coconut shells are collected well. And then further drying, drying, crushing, crushing and other steps. Convenient for subsequent processing.

2. Coconut shell carbonisation:
Preheating: The crushed coconut shells are sent to the coconut shell carbonisation furnace through the conveying device. Pre-heating is carried out first. The preheating temperature is controlled at 300-400℃. Remove the water and volatile substances in the coconut shell.
Carbonisation: After preheating, the temperature is increased to 600-800℃. Make the organic substances in coconut shell send pyrolysis reaction. Thus produce the finished coconut shell carbon. In the process of carbonisation, the temperature and time of coconut shell charcoal should be strictly controlled. Ensure the carbonisation effect of the final product.

3. Activation treatment:
Water vapour activation: React the carbide and water vapour at high temperature. So that the carbon atoms in the carbide are oxidised. Make it trip rich microporous structure. In this process, high temperature treatment is carried out. Temperature control at: 800-1000℃.
Activation by chemicals: Adopt chemicals to react chemically with the carbide. Facilitate the production of more micropores. So that it gets activated carbon with larger specific surface area.

4. Subsequent treatment:
After activation, the activated carbon is processed through subsequent steps such as cooling, crushing and sorting. The impurities in the coconut shell activated carbon are removed. According to the different particle sizes sorted out to meet different needs of use.

5. Quality testing:
The coconut shell activated carbon after production is completed needs to be tested for quality. Ensure that its quality meets the standard.
