Abstract

In this work, a PACKED BED REACTOR of methyl acetate HYDROLYSIS process has been studied. First, mass transfer limitations from bulk fluid to catalyst surface and then from surface into catalyst body were investigated quantitatively. Whereas diffusion had no any limitation on the overall rate of reaction, a pseudo homogeneous one dimensional model considering AXIAL DISPERSION COEFFICIENTS was developed. A LHHW kinetic model for rate of reaction and a Longmuir model for equilibrium adsorption of species on the catalyst, developed experimentally, were used in the mathematical model. An experiment of pulse-input feed to reactor was performed and concentration of reactor product versus time was determined. The model were solved by the numerical method of lines and the absolute difference between calculated concentration profile and those measured experimentally was defined as the objective function which was optimized by Levenberg-Marquardt OPTIMIZATION algorithm. A comparison of our model with ideal Plug Flow model and also with previous model in literature shows that this model is more accurate and more comprehensive than the others and can be used in many comparable industrial cases.
