Abstract：In order to improve the desulfurized capacity of the system from flue gas by using activated carbon, a series of experiments were made to compare the difference of performance between using activated carbon fiber (ACF) and using granular activated carbon (GAC). Experiments show that under the same working conditions, adsorption factor of ACF was 16.6 times as high as that of GAC, the adsorbent loss ratio of ACF was 1/14 of that of GAC, and the desorption efficiency can reach 99.8%. Conclusions were drawn that compared with the traditional methods of desulfurization from flue gas, the use of ACF can greatly economize adsorbent, obviously reduce the frequency adding new adsorbent, and reduce the equipment investment and operating cost, Therefore, the new method has obvious advantages in aspect of economization reliability and durability in system operating.
