In fact, the interaction among the gas, solid and liquid phases with the kinetic, mass and heat transfer mechanisms lead the system to have a challenging behavior. That is the case for the o-cresol hydrogenation to obtain 2-methyl-cyclohexanol, which is carried out in a three phase catalyst slurry reactor. A determinist mathematical model was developed using the mass and energy conservation equations for each phase, so that a system of differential equations is generated. In order to identify some suitable control structures an extensive dynamic behavior analysis was carried out. The controller implemented was a multivariable predictive controller based on the philosophy of Dynamic Matrix Control (DMC). The problem of optimization was solved through non-linear programming making use of the Successive Quadratic Programming (SQP) algorithm. ©2011 Walter de Gruyter GmbH & Co.
