Engenharia das Reacções Avançada

Objectives

At the end of the course the students should have acquired a solid basis on fundamental aspects of heterogeneous catalysis, their mecanisms and kinetic equations, treatment and design of heterogeneous catalytic reactors and non- ideal behaviour analysis of continuous reactors using the theory of residence times distributuion, that will enable them to: • Understand the heterogeneous catalytic phenomena. • Deduce the kinetic equation from a mechanism. • Discriminate mechanisms of heterogeneous reactions. • Manipulate the catalyst efficiency by predicting, detecting and regulating diffusion limitations. • Design heterogeneous catalytic reactors. • Detect and analyze deviations from the ideal reactors behavior. • Modelling real reactors.
