Investigation of the dynamics of the adsorption of water vapors by synthetic zeolites

Abstract

1. A universal bench setup for fundamental investigations of the dynamics of adsorption in a stationary layer of sorbent for various real adsorbent-adsorbate systems was designed and constructed. With negligible modifications in the design, the setup can be converted to a system of operation with a moving or pseudoliquefied layer of sorbent. 2. The characteristic features of this setup in comparison with analogous ones are: the possibility of conducting the experiments on the same vibration-compacted layer of charge of the sorbent and of obtaining five effluent curves in this case, corresponding to different lengths of the layer of charge of the sorbent; regeneration of the adsorbent directly in the adsorber itself; automation of the recordings of the experimental results. 3. The dynamics of the adsorption of H2O vapor in a stationary layer of granulated synthetic NaA zeolite at rates of gas flow from 0.1 to 5.0 liters/min·cm2, input concentration of H2O vapor from 0.1 to 3.2 g/m3, temperature of gas flow from 20.0 to 100.0°, and sensitivity of the analyzer of water vapor 0.1 mg/m3, was investigated on the setup.
