摘要:

The general thermodynamics in high pressure sorption processes and the isotopic shifts of the gases H2, N2, CH4und CO2were investigated by adsorption and desorption experiments on charcoal at pressures up to 25 MPa. The calculations of thermodynamic relations in the mentioned systems were carried out on the basis of a new three parameter equation for high pressure adsorption isotherms as well as a modified RAYLEIGH equation, in particular for the isotopic experiments.
