Research output: Chapter in Book/Report/Conference proceedingConference contribution


The adsorption and steam regeneration dynamics of VOC (toluene and acetone) in the fixed bed were studied experimentally and theoretically. Toluene as a non-polar solvent was insoluble in water, while acetone as a polar solvent was soluble in water. The adsorption isotherms of acetone and toluene vapors on the adsorbents exhibited type-II (BDDT classification) in the experimental range as multilayer adsorption. Water vapor showed type-V adsorption isotherm with condensation phenomena. Considering the physical properties and isotherms of the adsorbates, mathematical model was developed to predict the dynamic characteristics of steam regeneration in the fix bed. And all simulations were performed by gPROMS PDE solver. This is an abstract of a paper presented at the 2006 AIChE National Meeting (San Francisco, CA 11/12-17/2006).
