Coconut shell activated carbon is a high-quality adsorbent material, and its production process mainly includes the following steps:
1. Raw material collection: First, collect mature coconuts and process their shells, removing the outer fibers and leaving the coconut shells.
2. Carbonization treatment: Put the coconut shell into a high-temperature furnace for carbonization treatment, which means heating the coconut shell to high temperature under anaerobic conditions, causing carbonization reaction inside and generating high carbon content carbon materials.
3. Crushing and grinding: After carbonization, the coconut shell becomes more brittle and hard. Through the process of crushing and grinding, the coconut shell is transformed into small granular substances, increasing its surface area.
4. Cleaning treatment: Clean the ground coconut shells to remove impurities and residual substances, in order to improve the purity of activated carbon.
5. Activation treatment: The cleaned coconut shell carbon is activated using high-temperature steam or chemical activation methods to develop more microporous and mesoporous structures and increase the adsorption capacity of activated carbon.
6. Drying: Dry the activated coconut shell activated carbon to ensure its drying stability and ease of storage and use.
7. Screening and grading: Screen and grade the dried coconut shell activated carbon to obtain activated carbon particles that meet the specifications.
The production process of coconut shell activated carbon is simple, environmentally friendly, and has a wide range of material sources, making it an important adsorbent widely used in water treatment, air purification, decolorization, deodorization and other fields.
