| Single adsorption isotherms and differential enthalpies of adsorption of nitrogen were measured on a microporous-activated carbon at various temperatures. A new way for calculating the differential enthalpies of adsorption is presented, and the results obtained were compared to those obtained by the isosteric method derived from the equilibrium data using the Clausius-Clapeyron equation. The measurements were made thanks to a coupled thermostated calorimetric-manometric apparatus which can be operated for pressures up to 2.5 MPa and temperatures from 303 to 423 K. This article provides experimental data which can be used for the adjustment of interaction potential in computational simulations for supercritical adsorption. |
