Remarks on adsorbent surface barrier to adsorbate mass transport As the author passed away while this paper was undergoing peer review, the revisions suggested have been implemented by Timothy C. Golden, Air Products and Chemicals, Inc., Allentown, USA

The existence of a skin resistance for adsorbate mass transport at the surface of a pelletized adsorbent particle or at the surface of adsorbent crystals within a particle has been proven by many macroscopic and microscopic experiments. An isothermal and isobaric column dynamic test method may be used to approximately estimate the relative magnitude of the skin resistance.

Automated summary

The presence of skin resistance for adsorbate mass transport at the surface of a pelletized adsorbent particle or within a particle has been confirmed by various experiments, and an isothermal and isobaric column dynamic test method can be used to estimate the relative magnitude of this resistance.
