Chemical Reactors I

Recommended Prerequisites

Mass and Energy Balances, Transport Phenomena I, II and III, Modeling, Simulation and Optimization.

Teaching Methods

The syllabus will be taught in contact lectures with practical examples and discussion of the problems solved by the students. Whenever possible, the resolution of  home problems or in classroom will be proposed to students, aiming to promote a continued study. A continuous evaluation could be used along the semester with class tests (100%), being the last one referred to the overall content in order to integrate the global knowledge of the course.

Learning Outcomes

Development of competences in the domain of Chemical Reactors Engineering with ideal behavior, aiming the analysis and design of homogeneous reactors, including reactional systems for kinetic parameters determination. The Residence Time Distribution theory will allow the identification of the deviations of the ideal behavior of reactors. These studies will be in line with the new perspectives of Chemical Engineering molecular based, integrating multiscale systems analysis.
