Gas adsorption and Surface Diffusion on 5Å Microporous Adsorbent in Transition and Turbulent Flow Region

The flow of O2, H2 and CO2 was in transition regime at relatively lower delta T and then became turbulent at relatively higher delta T when passed through the 5A microporous zeolite adsorbent. Adsorption and surface diffusivity of all the gases that are being studied in these regimes increased with increase in delta T. For the temperature difference from 5 to 115 K, the range of adsorption of O2 was between 6.319x 10^-12 and 5.762x10^-11 kg/s. The adsorption ofH2 was between 4.4x10^-13 and 3.88x10^-12 kg/s for the temperature difference ranging from 1 to 20 K. The adsorption of CO2 was between 5.3x10^-12 and 4.9x10^-11 kg/s for the temperature difference ranging from 5 to 100 K. At pressure of 1 bar, CO2 adsorption was the highest at all delta T, followed by O2 and H2. Thesurface diffusivity increases with increase in delta T. At a particular delta T, the diffusivity increases asymptotically regardless of the flow regions.
