Introduction to formaldehyde removal activated carbon:

Gongyi Baolai water treatment formaldehyde removal activated carbon is a type of activated carbon that can remove formaldehyde. The method of using activated carbon to remove formaldehyde is called physical adsorption in the industry, which is different from chemical neutralization treatment such as gas catalyst formaldehyde removal.

Formaldehyde removalActivated carbon:
It can be divided into: wooden activated carbon, fruit shell activated carbon, animal bone/blood activated carbon, mineral raw material activated carbon, synthetic resin activated carbon, rubber/plastic activated carbon, regenerated activated carbon, etc; Common classification of activated carbon:
1. Classified by raw material source: Fruit shell charcoal (coconut shell, apricot kernel, walnut shell, olive shell, etc.) Coal charcoal, wood charcoal, etc. Among them, coconut shell material (especially Southeast Asian coconut shell) is recognized both domestically and internationally for its high strength, good adsorption performance, low ash content, and long service lifezuiThe characteristic of high-quality activated carbon raw materials is their high cost.
——Activated carbon made from coal as raw material is usually activated by steam or carbon dioxide gas. The shape of the product is mainly granular, and its pore size distribution is mostly microporous, which is more suitable for liquid-phase adsorption and gas-phase substances with smaller molecular weight and molecular diameter. Its advantage is relatively low production cost;
——Activated carbon made from sawdust is usually activated by chemical methods, and the shape of the product is mainly in powder form. Its pore size distribution can be controlled by adjusting the ratio of chemical activators, which is relatively flexible. It can produce products with pore size distribution mostly consisting of micropores or products with a large proportion of pores (transition pores) in the pore size distribution. It is more suitable for adsorbing substances with large molecular weight and molecular diameter in the liquid phase;
——Activated carbon made from fruit shells is usually activated by water vapor and carbon dioxide gas, and the shape of the product is mainly granular. Due to its special material, its pore size distribution is between the above two types of activated carbon, and its adsorption performance is excellent. Therefore, its application range is more extensive.
2. Classified by manufacturing method: gas activated carbon (or physical activated carbon), chemical activated carbon (or chemical activated carbon), chemical physical activated carbon.
3. Classified by appearance: amorphous granular activated carbon (also known as crushed activated carbon), formed activated carbon (or formed activated carbon), and powdered activated carbon.
4. Classified by the purpose of activated carbon: sugar activated carbon, wood vehicle activated carbon, air purification activated carbon, water purification activated carbon, oil and gas recovery activated carbon, pharmaceutical activated carbon, supercapacitor activated carbon, catalyst carrier activated carbon, etc.
5. Classified by material and purpose:
