Large scale analysis of coconut shell activated carbon

Coconut shell activated carbon: as the name suggests, the raw material is coconut shell. After finishing, it looks like black irregular particles. It is an activated carbon with strong adsorption. It is not only widely used in industry, but also widely used in life. At present, most coconut shell raw materials are imported. Vietnam, Indonesia and other countries have high-quality coconut shell products.

Simple steps for making coconut shell activated carbon:

The prepared raw materials are carbonized, cooled, washed, high-temperature, dried and screened to obtain the finished product of coconut shell activated carbon particles.

The process of making coconut shell activated carbon is generally simple:

1.carbonation

After the coconut shell is broken, it is dried at a high temperature of 170-600 ℃.

2. activation

The carbonized coconut shell is uniformly mixed with the solid and activated in the reactor. In the process of activation, nitrogen is added to the surface of coconut shell to protect the coconut shell and obtain the activated material.

3. cleaning

The active substance is soaked in hydrochloric acid and then rinsed with distilled water.

4. drying

Coconut shell activated carbon is washed and dried to produce the finished product of coconut shell activated carbon.

The yield of this method is very low, so it is usually treated with simplified steps. Of course, different activated carbon is different in different production steps. The production process of coconut shell activated carbon is very complex and the production process requires high requirements. Therefore, the coconut shell activated carbon produced has good adsorption and high price.
