What are the chemical components of ash in coconut shell activated carbon?

The more ash content of coconut shell activated carbon, the greater the impact on the adsorption performance of coconut shell activated carbon. Therefore, the ash content is one of the important factors that determine the quality of coconut shell activated carbon.

According to the classification of ash content, coconut shell activated carbon is generally divided into internal ash and external ash. coconut shell activated carbon for gold recovery In general, the internal ash will affect the adsorption performance of coconut shell activated carbon. Its main chemical components are: calcium oxide, magnesium oxide, titanium dioxide, sulfur trioxide, Potassium oxide, sodium oxide, etc.

Ash content is an important indicator in the selection of coconut shell activated carbon raw materials. The inorganic components in the raw materials hardly decrease during the carbonization process and remain in the charcoal. Even if the ash content in the raw material is only 1%, the ash content of coconut shell activated carbon may reach 10% or even higher.

Since ash has no adsorption capacity, the adsorption capacity of coconut shell activated carbon is directly proportional to its ash content, that is, the higher the ash content of coconut shell activated carbon, the lower its adsorption capacity. buy bulk activated carbon pellets Therefore, in the selection process of coconut shell activated carbon, the editor reminds everyone to choose products with low ash content to achieve better results.

Therefore, the ash content of coconut shell activated carbon is affected by the material. Different materials have different ash content of activated carbon. Generally, materials with soft texture have higher ash content. Because the ash blocks the adsorption capacity of coconut shell activated carbon, the adsorption performance is poor. Coconut shell activated carbon with low ash content is generally made of fruit shell or wood, which has a good pore structure, so this type of coconut shell activated carbon has better adsorption performance.
