The pore structure characteristics and specific surface area of activated carbon are usually obtained by measuring nitrogen adsorption isotherm at low temperature with adsorption In addition, the adsorption capacity of activated carbon also has a great relationship with its internal pore structure, pore size distribution and surface chemical properties. activated carbon manufacturers 

Chemical method in addition to certain micropores, macropores, there are more mesopores (transition pores), so it is more suitable for the application of liquid phase, adsorption of larger molecules of substances, such as sugar solution has a good decolorization effect;

When purifying water quality, it can also remove the colored material well and achieve the specified chroma  

Particle strength is also a main index of granular activated carbon.

In order to improve the particle strength of granular activated carbon, usually take some special processing measures, such as adding some material help plasticizing and proper mechanical treatment 4 or control in the process of kneading kneading temperature and kneading time, can greatly improve the strength of granular activated carbon particles, making the strength of the granular activated carbon has reached the fruit shell carbon intensity index.


For the gas phase adsorption, the size of the gas molecules is usually less than 1. ONM, the use of microporous activated carbon;

For liquid-phase decolorization refining, due to the large size of the liquid molecules, it is necessary to use activated carbon with developed mesopore.

Activated carbon has a large specific surface area and a particularly developed micro-pore structure, which is the main reason for its strong adsorption capacity and large adsorption capacity.
