Objectives
Fundamentals of Chemical Kinetics, Catalysis and Chemical Reactors, emphasizing Heterogeneous Catalysis Processes.
Program
1 - Chemical Kinetics
Classification of chemical reactions. Fundamentals of chemical kinetics and reaction mechanisms (overview). Chemical processes and catalysis: homogeneous and heterogeneous catalysis.
2 - Heterogeneous Catalysis
Definition of basic concepts and historical landmarks. Activity, selectivity and stability of catalysts.
General mechanism of catalytic reactions. Chemisorption and Langmuir's equation. Kinetics and mechanisms of heterogeneous catalytic reactions.
Catalyst types and activity correlations: metals, non-stoichiometric oxides and acids. Bi-functional catalysts. Zeolites and shape selectivity.
Components of a catalyst: supports, active phases and promoters. Methods of preparation. Deactivation mechanisms and catalysts regeneration.
3 - Introduction to Chemical Reactors: Ideal Models
Classification of chemical reactors. Material balances. Ideal models: the batch reactor, the plug flow reactor and the stirred tank reactor.
Kinetic analysis of experimental data.
Design of chemical reactors and reactor associations. Selection and optimisation methods.
4 - Examples of Catalytic Processes
Detailed study of some selected catalytic processes, emphasizing the relationships between process chemistry and engineering,

Teaching methods and learning activities
The course consists of three 1-hour lectures per week and 1 hour of tutorials. The fundamentals and examples are presented in the lectures, while the tutorials are dedicated to problem solving. A collection of problems is given to the students as homework.
Evaluation Type
Distributed evaluation with final exam
Eligibility for exams
The students should not exceed the allowed number of absences (25% of the scheduled tutorials) and must attend both tests (except in justified circumstances).
Calculation formula of final grade
The final classification (CF) will be the best of either
CF = 0.1 (CT1 + CT2) + 0.8 CEF
or
CF = CEF
where CT1 and CT2 are the classifications obtained in the tests and CEF is the final exam classification.
Special assessment (TE, DA, ...)
These students, and those that have already followed the course in previous years, are excused from the tutorials. However, they are allowed to attend the two interim tests if requested in writing by 21st October 2003.
Classification improvement
There will be another exam that the students can attend to improve their classification.
