It has been studied the interaction of coals ranging from brown coal (Cdaf=70.4%) to anthracite (Cdaf=95.2%), with equimolar nitrating system HNO3-Ac2O (20-2C) yielding nitrated coals named as structurally modified coals (SMCs). In comparison with the parent coals, SMCs have more disordered structures contain aromatic NO2 groups and different oxygen functionalities as substitutes. Besides, SMCs are more thermolabile comparing with parent coals. Nitrated coals are better precursors of active carbons and may be activated by KOH into adsorbents with surface area as high as 1200 in 2/g.
