Abstract

In this work, isotherms of absolute adsorption of methane on microporous AU-1 carbon adsorbent have been measured in the pressure range from 30 Pa to 6 MPa and temperature range from 178 to 273 K. Adsorption isosteres of methane have been plotted according to experimental data. Isosteres are approximated well by lines in lnp = f(1/T)a coordinates. Differential molar heats of adsorption of methane on this adsorbent have been calculated on the basis of experimental isotherms. Theses regarding the structure of adsorbed substance based on thermodynamic analysis have been proved by molecular-dynamic calculations.
