Abstract

Using a high-precision volumetric—gravimetric experimental unit, the adsorption iso-therms of methane, argon, and nitrogen were measured at pressures of 0.1—40 MPa and at temperatures of 303—373 K on four carbon adsorbents with different porosities. To calculate the characteristic energy and average heat of adsorption of gases in the supercritical region, two parameters, which characterize an adsorptive were introduced: critical temperature T c of the gas and the analog of the saturated vapor pressure “P s”, which is defined assuming that densities of an adsorbate and an adsorptive are equal. The average heats of gas adsorption well agree with the average isosteric heats for the adsorption systems over the entire pressure and temperature intervals under study.
