Conclusions

  1. 1.

    The rate of establishing adsorption equilibrium at temperatures below 170°K decreases sharply, so that the equilibrium adsorption of a mixture of gases with nitrogen on NaA zeolite can be investigated only above 170°K.

  2. 2.

    The presence of a Henry region on the nitrogen and oxygen adsorption isotherms at various temperatures gives yet another independent method for the determination of the initial differential heats and can simplify to a considerable degree the calculation of the thermodynamic functions which characterize the adsorption equilibrium of a binary mixture.
