Multiphasic Reactors

Recommended Prerequisites

Mass and Energy Balances, Fluid Dynamics, Heat Transfer, Mass Transfer, Modeling, Simulation and Optimization, Programing and Numerical Methods, Introduction to Reaction Engineering; Chemical Reactors  

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

This course has as objevtive to consolidate knowledge in the area of the chemical reaction engineering with special emphasis for the multiphasic systems. Thus the goals are the 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
