Can you tell the difference between nutshell activated carbon and coal-based activated carbon? from Carrie Ge's blog


There are thousands of types of activated carbon on the market. The simple way of distinguishing the quality of activated carbon is mainly from the appearance and material. Generally, the adsorption capacity of activated carbon from the shell is stronger than that of coal-based activated carbon, but how to distinguish the shell of the activated carbon with the same specification Charcoal or coal-based charcoal?


The following briefly describes the difference between the two:


Choosing coconut shell activated carbon also belongs to nut shell activated carbon. Because coconut shell has developed pores, light material, and low density, it is a good material for making activated carbon at present. Therefore, coconut shell activated carbon is currently a good activated carbon. coal based activated carbon granular If the same weight of coconut shell activated carbon, Nutshell activated carbon is put together with coal based activated carbon. Coconut shell activated carbon has the largest volume, followed by nutshell activated carbon, and coal based activated carbon is smaller.


The formed coconut shell activated carbon or nut shell activated carbon is mostly broken particles and flakes, showing irregular particles as a whole; most of the coal-based activated carbon is columnar, spherical, etc., and the shape is relatively regular.


Because the shell activated carbon has a low density, a light material, and a larger pore space than coal-based activated carbon, the two can be placed in water for comparison. Generally, because the coal-based activated carbon has a heavier material, it will sink quickly when placed in water; Water will absorb water molecules first, and then slowly sink after the adsorption is saturated. This process is much slower than coal-based activated carbon.


Nutshell activated carbon and coal-based activated carbon will produce bubbles when placed in water, but the bubbles are also different. Nutshell activated carbon has many developed pores, and its bubbles are relatively small and dense; coal-based activated carbon is a macromolecular pore structure, and its bubbles are relatively large and thin.


Although the adsorption capacity of husk activated carbon is stronger than that of coal-based activated carbon, the price of husk activated carbon is much higher than that of coal-based activated carbon. When using it, you need to choose the corresponding activated carbon according to different needs.
