The Determination of Mass Transfer Characteristics of a Column for Sulphur Dioxide Adsorption in 13 X Zeolite Working in Unsteady-State Regime

Abstract

In the present work, the mass transfer characteristics such as the lenght of mass transfer unit (LMTU), the break through time and column saturation time have been studied in the case of sulphur dioxide adsorption on 13 X zeolite. The adsorption column was working in unsteady-state conditions. For these determinations a chromatographic method has been used, permiting the direct inregistration of breakthrough curves, whose shape depends on adsorption conditions (gas concentration, temperature, the size of adsorbent grains, gas velocity). The method is very sensitive, reflecting all changes of adsorption parameters.

“…7 Possessing some disadvantages, such as high energy requirements, 8 toxic sludge, 9 releasing of nanoparticle to environment, 10 stability of adsorbents, and agglomeration of the nano-adsorbents during adsorption 11 process are still challenging issues for this absorbent. Zeolites have been applied in various procedures such as separation 12 and filtration 13 due to their specific porous structures and mobility 14 being useful to purified water.…”
