The study is focused on modeling of separation process and *** adsorption separation process is *** surfactin production process by Bacillus subtilis ATCC 21332 followed by surfactin adsorption in a fixed-bed column packed with commercial active carbon is studied in *** adsorption column achieves high surfactin recovery(94%)by up-flow methanol elution at 25°*** adsorption column is simulated with a complex one-dimensional plug flow dispersion model coupled with nonlinear adsorption equilibrium,based on the assumption that the adsorption of surfactin is monomolecular layer and no micelle is *** molecular diffusion coefficient of surfactin in water solution with electric neutrality is estimated to be 0.428×10 -5 cm 2 ·s -1 by molecular dynamics *** model developed can describe the complex interplay of adsorption kinetics,fluid dynamics,and mass-transfer phenomena based on the assumption of no radial temperature and concentration gradients,and is of adequate *** work involved in this paper is valuable for the optimization of the production process of surfactin.

Understanding the interaction between a fluid and a solid phase is of fundamental importance to the design of an adsorption *** the heat effects associated with adsorption are comparatively large,the as-sumption of isothermal behavior is a valid approximation only when uptake rates are relatively *** this article,we propose to determine when it is needed to choose the isothermal or non-isothermal assumption according to two physical parametersα（ratio convection/capacity） andβ（quantity of energy/capacity） .The proposed problem is solved by a mathematical method in the Laplace ***α→∞（infinitely high heat transfer coefficient） or β→0（infinitely large heat capacity） ,the limiting case is *** the diffusion is rapid（α10） the kinetics of sorption is controlled entirely by heat *** the adsorption process is to be used as a heat pump,it shall be represented by an isotherm model withαandβas high as possible.
