摘要
The specific surface and porosity of Belovo coal are determined. Coal samples undergo adsorption-structural analysis at the liquid-nitrogen temperature and at different relative partial pressures, on Sorbi N.4.1 and Termosorb TPD 400 instruments and also on the Micromeritics ASAP-2020 static vacuum system.
