摘要
The possibility of describing the isotherms of adsorption on microporous adsorbents at supercritical temperatures using the Dubinin-Radushkevich, Dubinin-Astakhov, and Tolmachev-Aranovich equations, in which the adsorbtive saturated vapor pressures that serve as the standard pressures below critical temperatures are substituted for the standard pressures (P (s) (*) ) found by the linear extrapolation of the dependences of adsorbtive saturated vapor pressure on the inverse temperature to the supercritical region, is shown. The possibility of linear extrapolation is substantiated by the data of a numerical experiment.
