(395ak) Experiment and Simulation Study of Multi-Component Gas Adsorption On MSC3A By Volumetric Method

(1)  Introduction.

 MSC (Molecular Sieving Carbon) has slit like micropores, which separate different size molecules by molecule’s different diffusivity.

In this study, the adsorption experiment was conducted by the volumetric technique. MSC 3A (KURARAY CHEMICAL CO., LTD) was used as adsorbent at 303K, 313K and 323K. Experimental adsorption of binary mixtures was compared with the simulation using the data obtained in equilibria and rates of adsorption of the single component.

(2) Study on gas phase adsorption by a volumetric method.

 Equilibria and rates of adsorption of nitrogen, methane and binary N₂-CH₄ mixtures into molecular sieving carbon(MSC3A) were studied by the volumetric method.

  Micropore diffusion, mass transfer coefficient are obtained by making an ideal curve and curve fitting of the pressure change about the analysis of the adsorption rate.

Equilibrium of single component was correlated by Langmuir equation and Markham Benton equation.

(3) Conclusion

A detailed value of the data obtained from mixed-gases experiments between experimental and simulated chromatogram, which were based on the modeling of Stop & Go method, are corresponding. And micropore diffusivities obtained were interpreted by chemical potential driving force consideration based on non-equilibrium thermodynamics law.
