Conclusions

-- It has been found that the investigated pitch carbon fibers are ultra- and microporous adsorbents with a strongly developed surface.

-- The studied fibers display clearly expressed molecular-sieve properties.

-- With increase in activation time, the size and volume of the pores and the specific surface of the specimens increase, while the chemical activity of the surface changes only slightly.
