The specific surface area of several kinds of zeolite, ie., Moleculite 515, Moleculite 4P-30S, Zeoharb 501, Zeoharb 502 and Itaya zeolite was estimated on the basis of the PSA (Pressure Swing Adsorption) method. PSA is accompanied by the evolution of heat and its adsorption in the zeolite bed with a corresponding recorder deflection.
The results were compared with the data obtained by other adsorption methods utilizing nitrogen. This PSA method seems useful for estimation of specific surface area of zeolite as well as life estimation of zeolite adsorbent in a dynamic adsorption process.
