Effects of oxygen functional groups and FeCl₃ on the evolution of physico-chemical structure in activated carbon obtained from Jixi bituminous coal.

ABSTRACT: It is crucial to increase the values of S _BET/burn-off ratio to achieve activated carbon (AC) with a higher SO₂ adsorption capacity at a low cost from flue gas. In this study, at first, Jixi bituminous coal was used as a raw material to prepare a series of pre-treated samples by oxidation treatment and adding different amounts of the FeCl₃ catalyst. Then, the AC samples were prepared by pyrolysis under a N₂ atmosphere and physical activation with CO₂. Finally, the change in the physico-chemical structure of different samples was determined to study the effects of oxygen functional groups and FeCl₃. The results show that the rapid growth of mesopores is mainly influenced by the evolution of oxygen functional groups, wh
