Description
  • Various pre-treatment procedures were applied on a sample of a subbituminous coal. Variously dried samples with known residual moisture contents were interpreted according to the microporous textural parameters. Adsorption isotherms of CO2 at 30°C were determined using a volumetric sorption analyser. Adsorption data were evaluated according to Dubinin-Radushkevich and Medek?s equation in order to determine micropores? volume and micropores? surface and modus of the micropores? radii. It was found that the drying method has an influence on the microporous textural properties. Samples which were not exposed to oxygen during drying (vacuum drying, inert gas purging) have better micropore characteristics; likely due to the lower contents of the residual moisture in the order of a few tenths wt.%.
