Conclusions

  1. 1.

    An analytical solution has been found for the model of mixed-diffusion adsorption dynamics on a biporous adsorbent in the case of a rectangular isotherm with account of three kinds of resistance to mass transfer: external, in transport pores, and in microporous zones.

  2. 2.

    In the region of small relative breakthrough concentrations the final curves in the coordinates In y-t are linear. The loss of time of protective action in Shilov's equation is a linear function of the relaxation times which are characteristic for three different kinds of mass transfer.
