Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    The equations for internal diffusion in biporous adsorbents have been analyzed for the case of a rectangular adsorption isotherm.

  2. 2.

    A finite adsorption wave front boundary, advancing with the passage of time, is established in microporous adsorbents having a bidispersed structure and a rectangular adsorption isotherm.

  3. 3.

    For the case of a rectangular adsorption isotherm, analytical equations relating the moments of the kinetic curve and the function describing the frontal movement have been established.
