Coconut shell activated carbon belongs to the category of nut shell activated carbon. Its main characteristics are low density and light touch. The weight in the hand is significantly lighter than coal-based activated carbon. With the same weight of activated carbon, the volume of coconut shell activated carbon is generally larger than that of coal-based activated carbon.
The shape of coconut shell activated carbon is generally broken granular or flake, while the shaped activated carbon, such as columnar and spherical activated carbon, is mostly coal-based carbon.
Because coconut shell activated carbon has a low density and a light feel, it can be put into water. Coal-based charcoal generally sinks faster, while coconut shell activated carbon floats in the water for a longer time. As the activated carbon adsorbs water molecules to saturation When the activated carbon sinks to the bottom, you will see a small bubble wrapped around each activated carbon, which is crystal clear and transparent, which is very interesting.
Coconut shell activated carbon has a small molecular pore structure. When activated carbon is placed in water, the air discharged when it adsorbs water molecules will produce many very small blisters (just visible to the naked eye), densely floating to the water surface. The coal-based activated carbon generally has a macromolecular pore structure, and the bubble phase produced is also relatively large.
