Initial stage of internal diffusion adsorption kinetics in adsorbents with a biporous structure

  • 23 Accesses

Conclusions

  1. 1.

    A study was made of the initial stage of internal diffusion adsorption kinetics in adsorbents with a biporous structure for the case of linear isotherms.

  2. 2.

    An analysis of the kinetic curve at this stage makes it possible to approximately estimate the characteristic times of diffusion relaxation T andτ under the given experimental conditions.
