    Figure 3

    Cosorption enthalpy (absolute value) of H2O and SO2 on cork powder at 298 K versus loading (open symbols). Initial composition of the mixture: 0.67 SO2 + 0.33 H2O. Sorption enthalpy of single components are also reported (a: liquefaction enthalpy of water = 44 kJ.mol−1; b: liquefaction enthalpy of SO2 = 22.9 kJ.mol−1).

    Total and partial sorption isotherms of water and sulfur dioxide for the binary mixture composed of 0.33 molar water and 0.67 molar sulfur dioxide.

  • Figure 5
    Figure 5

    Dependence of the total loading on the sorption selectivity of SO2 with respect to H2O at 298 K. Initial molar composition of the mixture: 0.67 SO2 + 0.33 H2O.
