Adsorption constants and kinetic coefficients evaluation for H(2)/D(2) separation on Na-, Ca-, Ni- mordenites
The capacity of Na-, Ca- and Ni-mordenites for separation of H(2)/D(2) mixtures has been determined by a set of gas-chromatographic runs. The theory of moments has been applied to the chromatographic peaks related to pure hydrogen and deuterium, in order to determine not only the adsorption constants but also the kinetic parameters of the separation process. In this study, the variation of the pressure along the chromatographic column has been considered. For different flow rates of the carrier gas and temperatures ranging from 150 to 190 K, pressures and concentrations of the adsorbed components, granulometry of the sorbents, the equilibrium adsorption constants and the kinetic parameters have been determined. The values obtained have shown that these sorbents are very promising for diagnostic purposes and for application to gas-solid exchange processing units, such as the pressure swing adsorption (PSA) and the pressure swing parametric pumping (PSPP) for H(2)/D(2) separation of large volumes of gases.
