摘要：

In this paper, we present an automatic apparatus for measurement of adsorption of gases on microporous media at constant temperature. Our method is based on a static volumetric method. This apparatus allows one to obtain adsorption isotherms in the ranges 0-4000 kPa and 273-373 K. This wide range of pressure allows one to reach saturated pressure for many gases and to study capillary condensation when the pressure tends to the saturated pressure. Software developed in our department controls the electrovalves and carries out temperature and pressure measurements. Characteristic isotherms are presented of adsorption of ethane on activated carbon at 278 and 303 K in the range 76-3607 kPa.
