Adsorption of Hydrogen Mixture Gas on Zeolite 5A and Activated Carbon

Abstract

Adsorption experiments for hydrogen mixture gas on zeolite 5A and activated carbon. Adsorption equilibrium of gas were measured to use the static volumetric method. The experiment data were fitted very well with Langmuir-Freundlich isotherm equations. Here, multi-component adsorption equilibria were predicted by using the parameters obtained from single component adsorption isotherm. The binary data were verified by well-known isotherm models: extended Langmuir, extended Langmuir-Freundlich, ideal adsorbed solution theory and vacancy solution model. As a result, the models were found to describe the experimental data with a reasonable accuracy. In especial, extended L-F model and Dual-site Langmuir predict equilibria of mixture better than any other models. On the other hand, dynamic experiments for hydrogen mixtures were conducted in a single and layered bed under various operating conditions.
