In addition, stabilization methods were studied to overcome the low yield when spherical activated carbons are manufactured from anion exchange resins. Diverse properties of anion exchange resins such as the structures and functional groups were found to have large effects on the shape of the manufactured activated carbons. The porous structure of anion exchange resins was found to form cracks in the activation process, and the dimethylethanolammonium functional group was found to be unable to maintain the spherical shape due to its very low thermal stability. The O2 stabilization process was determined to be a very effective method for improving the yields of activated carbons manufactured from strongly basic anion exchange resins. However, activated carbons manufactured by carrying out a stabilization process in a gas containing O2 showed a decrease in benzene adsorption under a relative pressure of 0.01 or lower due to an increase in the O2 content, and the excessive or limited cross-linking on the surface changed the shape of the activated carbons. Therefore, it is necessary to manufacture activated carbons considering whether they are stabilized or not and under conditions depending on the type and properties of the adsorbate. As a result of a benzene breakthrough experiment, activated carbons manufactured from anion exchange resins showed smaller performance decreases ranging from 7.0% to 9.0% in humid conditions compared to dry conditions. Therefore, anion exchange resins were identified as suitable precursors for manufacturing activated carbons for application to highly humid actual processes.
