Abstract Adsorption can be used to recover effectively the volatile organic gases (VOCs) in the exhaust gas from factories through using an appropriate adsorption bed. Due to form a physical or chemical bond, adsorption occurs between the porous solid medium and the liquid or gas multi-component fluid mixture. The regeneration capacity of the adsorbent is as important as the adsorption capacity and it determines the economics of the adsorption system. The regeneration of adsorbent can be realized through changing the pressure or temperature of the system. Here, activated carbon samples from coconut shell were prepared and… More > Graphic Abstract

Abstract In this work, a combination of computational fluid dynamics (CFD) and porous media model was applied to simulate the benzene adsorption on activated carbon and the flow fields in a porous media. The three dimensional unsteady state the gas flow was modeled by using the laminar one phase flow equations in conjunction with the mass transfer equation. The adsorption rate on solid phase was implemented to the model by a user defined source. The model was validated by comparing the simulated breakthrough curves by experimental data. After the validation of the model, the effects of More >
