Description
Technical Field

[0002] Fruit shell activated carbon is a kind of activated carbon prepared from natural fruit shell raw materials. It is through a series of physical or chemical treatments that the carbonaceous material in the fruit shell has a large number of micropores and mesoporous structures, thus giving it excellent adsorption and catalytic properties. Potassium hydroxide activation can produce activated carbon with a high specific surface area. After the fruit shell and other raw materials are activated by potassium hydroxide, the activated carbon formed has more micropores and mesoporous structures, thus having a larger specific surface area and improving its adsorption capacity. During the potassium hydroxide activation process, the pore structure of the activated carbon can be controlled, including the formation of micropores, mesopores and macropores. The regulation of this pore structure helps to improve the adsorption performance and selectivity of the activated carbon.
