Conclusions

  1. 1.

    The rate of adsorption of n-butane by large particles of CaA zeolite is governed by intraparticle diffusion.

  2. 2.

    In the range of surface coverages 0.25 to 3 molecules per cavity, intraparticle diffusivities rise with increasing surface coverage.

  3. 3.

    The activation energy for intraparticle diffusion and the preexponential factor decrease with increasing surface coverage.

  4. 4.

    Intraparticle diffusivities obtained from nonequilibrium kinetic adsorption measurement are in satisfactory agreement with self-diffusivities obtained by pulse gradient NMR.
