Rigorous Mathematical Modeling of the Adsorption System with Electrothermal Regeneration of the Used Adsorbent

Abstract

This report results from a contract tasking University of Belgrade as follows: The contractor shall model a known and existing single absorber of the hollow cylinder, several layers of activated carbon cloth. radial gas flow type. Modelling will incorporate: 1. Modeling of adsorption: Models of different complexity (local equilibrium, film mass transfer with or without dispersion, pore-surface diffusion, micropore diffusion and their combinations) of the hollow-cylinder absorber with radial gas flow will be established. 2. Modelling of heating of the bed by electric current: Model the thermal behavior of the adsorbent bed. This model will include the modelling of the electrical field within the absorber bed as well as the dominant heat transfer mechanisms. As a result. the temperature field within the bed can be predicted. 3. Modelling of electro-thermal desorption: Integrate the thermal model and the model or models for mass transfer. chosen as the most appropriate in the first phase (modeling of adsorption). This integration is not mechanical. as there is essential coupling between the heat generation and heat transfer on one, and mass transfer on the other hand. As a result. it will be necessary to estimate additional or correct the models parameters estimated in the previous stages.
