Description
The concentration dependence of sorption rates of selected gases on chabazite has been determined and interpreted in terms of the various rate controlling mechanisms present. Argon and several other gases exhibit concentration independent activated diffusion into the bulk of the zeolite. Freon 21 occupies only the pores or crevices of the mineral, and the rates are controlled by Knudsen or gaseous bulk diffusion, depending on the concentration range. Finally, carbon dioxide sorption rates strongly increase with sorbate concentrations. This probably means that a low concentrations the slow adsorption on the internal sites is the rate controlling process, while at higher concentrations the diffusion rate of the gas into the bulk of the zeolite becomes important.
