Activated carbons prepared by steam activation of chars produced by pyrolysis of polyacrylonitrile (PAN) and its blends with coal-tar pitch (CTP) were used as the adsorbents of sulphur dioxide. The pore structure was examined by adsorption of nitrogen, benzene and carbon dioxide. Surface chemistry w
