CFD Modeling of Adsorption in Packed Bed Micro Reactors

A numerical model has been developed to simulate the adsorption of chemical species inside columns filled with solid adsorbent particles. In this model hydrodynamics, mass transfer and adsorption equilibrium are accounted for. In order to investigation of momentum phenomena we used Brinkman-Forchheimer, non-darcian model and for mass transfer and adsorption we used the various transport model. The CFD simulation was carried out using FLUENT 6.2 to calculate the conservation equations. In this study the user defined files in the fluent were created to make fluent to be suitable in the application of adsorption simulation. The comparsion results show that the simulation result can agree experimental results. Therfore, it can be concluded CFD is a suitable tool to predict the adsorption of components inside of packed columns such as chromatographic columns.
