Compulsory
1st Cycle Studies
Recommended Prerequisites
Mass and Energy Balances, Transport Phenomena I, II and III, Modeling, Simulation and Optimization, Chemical Reactors I.
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 Catalytic Reactors Engineering, under heterogeneous catalysis, efficiency of solid catalysts, analysis and design of multiphase systems and multifunctional reactors.
