Equilibrium Volumetric Experiment Apparatus Review for Mixed-Gas Adsorption

Abstract

This research aim is to identify the additional equipment and system functions required to set up an experimental system for mixed-gas dynamic adsorption using equilibrium volumetric technique. As well as to review the process variables’ effect on adsorption capability, while using an experimental system apparatus consisting of an equipment previously mentioned in selected papers. In this study, the selected experimental research on mixed-gas adsorption is reviewed, which used the equilibrium volumetric method. The relationship between process variables and adsorption capacity, kinetics, and diffusional mass transfer are observed. The correlation between adsorbate concentration, adsorption temperature, pressure during adsorption process, flow rate of adsorbate and adsorption capacity indicates that using additional equipment in the experimental mixed-gas dynamic adsorption is feasible. The correlation between these parameters is in agreement with common understanding of adsorption. The predicted adsorption capacity and analysis of kinetics adsorption are consistent with the model. The diffusional mass transfer could explain a diffusional step of the adsorbate onto the adsorbent.
