RESUMO

In this work, a study on the mathematical modeling of a three-phase catalytic surry reactor is developed, using two approach. In the first, the reactor is described by their phenomenological equations expressing the mass and energy balances for the system. In the second, artificial neural network techniques is considered in representing the three-phase reactor behavior. Initially, a revision of existing literature on three-phase reactor mathematical modeling and on artificial neural networks application in the chemical process analysis is presented. After, the deterministic mathematical model formulation for a three-phase catalytic slurry reactor, with a tubular configuration and operating in steady-state is developed. In the mathematical model the mass and energy balance equation for the catalytic particle are considered. The mathematical model developed is simulated and the main results are presented and discussed, highlighting the effect of the principal parameter of the process in its performace, and using data obtained by the mathematical model simulation, the applicability of artificial neural networks techniques is shown.
