Activated carbon is a strong adsorbent, the adsorption of gas and adsorption capacity are very large.

When the gas molecules occupy the adsorption surface of activated carbon, the adsorption of activated carbon will be reduced, resulting in the so-called "poisoning" of activated carbon.If there is oxygen on the activated carbon adsorption, sometimes also make the adsorption of the material oxidation reaction., before the use of activated carbon, most of the gas must be removed by adsorption.activated carbon pellets manufacturer 

Usually remove the gas in activated carbon there are two methods, one method is to use ephedrine or hydrogen sulfide saturated water solution treatment, but this treatment method is too complex, and through these treatments can also cause some other side reactions, so it is not commonly used.Another method is to heat drying, can be adsorbed most of the gas I body removal.It is usually heated and dried at 150C for 4 to 5 hours before use.Because of the high temperature of nylon deformation, nylon activated carbon before use at 100 ° C heating and drying 4 to 5 hours.Activated carbon has no adverse adsorption effect on some substances, causing some substances to adsorb on it can not elute.coconut shell activated carbon suppliers 

Therefore, in the separation of activated carbon adsorption of the material, must first activated carbon deactivation. Principle of activated carbon adsorption

activated carbon is a kind of very small granular has a large surface area, and more tiny holes in the granular - capillary. The capillary has very strong adsorption capacity, due to the granular surface area is large, so a good contact with with gas (impurities). When these gases (impurities) encounter capillary by adsorption, purification effect. Activated carbon surface area of the study is very important, only the BET specific surface area detecting data of active carbon method detected result is reliable, domestic at present there are many instruments can only make direct comparison method of detection,
