The purpose of this research is to study the modeling of adsorptivedistillation (AD) on ethanol-water mixture purification using natural and synthetic zeolites as adsorbent. The synthetic zeolite type used was zeolite 3A. AD is an effective way to purify ethanol-water mixture so that it can produce pure ethanol as fuel. Natural and synthetic zeolites as adsorbent are quite promising for industrial application. The experiment was conducted in a batch operation. Four AD modellings are developed based on four different simplifications, i.e., quasi-steady-state with no axial dispersion (Model 1), unsteady-state with no axial dispersion (Model 2), quasi-steady-state with axial dispersion (Model 3) and unsteady-state with axial dispersion (Model 4). The equilibrium equation correlating water content in vapour and water content in adsorbent particle was approximated by Henry's law model. © Penerbit Universiti Sains Malaysia, 2018.
