Objectives
This course aims to acquaint students with reaction kinetics, catalysis and chemical reactors
Program
1- Kinetics of chemical reactions
Classification of chemical reactions; Revision of fundamental notions of chemical kinetics and reaction mechanisms; chemical processes and catalysis: homogeneous and heterogeneous catalysis
2- Heterogeneous catalysis
Definition of basic concepts and historical overview; Activity, selectivity and stability of catalysts;
General mechanism of catalytic reactions; chemical adsorption and Langmuir equation; Kinetics and reaction mechanism of heterogeneous catalysis;
Types of catalysts and activity correlation: metals, nonstoichiometric oxides and acids; bifunctional catalysts; zeolites and selectivity;
Catalysts components: supports, active phases and promoters
Supported catalysts: characteristics of the metallic phase
Deactivation mechanisms; catalysts regeneration
3- Introduction to Chemical Reactors: Ideal Reactors
Characteristics of chemical reactors; material balance equation; ideal models: closed, piston and agitated reactor.
Analysis of experimental data to determine reaction kinetics;
Methods of selection and optimization of reactors
4- Examples of catalytic processes
Detailed study of some industrial catalytic processes: relation between process chemistry and engineering solutions

Teaching methods and learning activities
This course is divided into general theoretical-practical classes (3 hours per week) and group theoretical-practical classes (1 hour per week). In the first concepts and examples are presented, while the second is tutorial oriented (problem solving and doubts).
Evaluation Type
Distributed evaluation with final exam
Eligibility for exams
Students have to attend to 6-9 micro-tests, they are not scheduled and will last around 15 minutes.
Students have to attend classes and the micro-tests.
Calculation formula of final grade
Students’ assessment will be based on the following formula:
C = 0,2 Ca + 0,8 E
Ca- continuous assessment (average of the micro-tests; the 2 or 3 worse results will not be taken into account)
E- Exam
Examinations or Special Assignments
A closed book exam, which is divided into two parts. Students cannot use calculators in the first part of the exam.
Special assessment (TE, DA, ...)
Students with a special status (working students, military personnel) and students who attended to the course last year, do not need to attend to theoretical-practical classes.
