Abstract: | Physisorption equilibria of multicomponent gases on microporous solids like zeolites or activated carbons are considered. An overview about adsorption measurements of pure gases H2, He, O2, N2, Ar, CO2, CO, CH4, C2H4 and C2H6 and some of their mixtures in the pressure range vacuum < p < 50 MPa at different temperatures 10∘C–70∘C were investigated. Also a thermodynamic formalism based on a modified van Ness method and on a new 3 parameter Isotherm equation (3-PIG) to describe the excess amount adsorbed was developed. Results are shown and discussed. Dedication to the memory of W. Schirmer. |
