✦ Synopsis

new equation for gas adsorption on microporous solids is proposed on the basis of the exponential adsorption isotherm. which is generated by the virial expansion of the spreading pressure. Expressions associated with this equation are derived also for the adsorption potential distribution. the differential molar enthalpy, and the differential molar entropy of adsorption. It is shown that this equation gives a good description of benzene adsorption on activated carbons with different degrees of microporosity and structural heterogeneity.

Experimental excess adsorption isotherms of nitrogen on activated carbon were measured in the range of 103-298 K and pressures up to 10 MPa. A method for determining the volume of the adsorbed phase from the experimental data for the supercritical temperatures was proposed. Such a volume with a new
