Surface areas of cokes including blast furnace use, foundry use and general use were measured by adsorption method using carbon dioxide (195°K), methanol (298°K) and nitrogen (77°K) as adsorbates.
Surface areas obtained from carbon dioxide, methanol, and nitrogen were 1-57 m2/g, 0.8-6.5m2/g, and 0.3-2.1m2/g respectively.
Surface areas from carbon dioxide were closely correlative with moisture contents of cokes and specific volumes of cokes measured by using water as replaceing agent.
It was seen considerable agreement between the surface areas from carbon dioxide and those from the adsorption isotherms of water, which were obtained from moisture contents of cokes at various humidity of atmosphere, using Kelvin's equation.
