Conclusions

  1. 1.

    In the adsorption of n-butane by CaA zeolite from a one-component gas phase, the relative role of diffusion in transport pores decreases with an increase in the degree of filling, and the role of the thermal component increases.

     
  2. 2.

    The contribution of the thermal component increases with a decrease in the size of the adsorbent granule, and when the thickness of the plate is 2L < 0.01 cm, the adsorption kinetics are basically determined by the rate of dissipation of the heat of adsorption with all degrees of filling studied.
