Learning unit contents
The course aims at developing the concepts required to use heterogeneous catalysts in various chemical processes. It contains the following concepts:
- Catalyst definition, types of catalysts.
- History of catalysis - historical processes.
- Industrial applications: relationship between process, reactor and catalyst;
- Physical and chemical steps in heterogeneous catalysis (diffusion, adsorption, reaction, desorption);
- Definition of catalytic sites - catalysis by metals, alloys and surface groups.
- Conversion ratio, activity, selectivity, turnover number
- Identification and counting of catalytic sites. catalyst characterization.
- Nature and synthesis of supports and active phase. catalyst shaping.
- Coupling between reaction and diffusion in porous catalysts (mass and heat transfers, efficiency factor, diffusional limitation
- Deactivation
Learning outcomes of the learning unit
Master the concepts of catalyst preparation and characterization.
Be able to use a supported catalyst in a reactor and to determine the operating conditions (chemical vs. diffusional regime).
Prerequisite knowledge and skills
Chemistry (CHIM9272-2 and CHIM9273-1) Chemical kinetics (CHIM0012) Chemical engineering - reactor study (CHIM0023-3)
Planned learning activities and teaching methods
Theory lessons with numerous real examples about the preparation, characterization and use of catalysts.
Exercises about characterization data treatment and the study of reaction-mass transport coupling.
One personal presentation (in English) on a predefined subject.
Mode of delivery (face-to-face ; distance-learning)
- Lectures (theory), autumn session (face-to-face). 17 sessions of 1.5 h.
- Practice, parallel to theoretical lectures (face-to-face). 9 sessions of 1.5 h.
- Language : English
Recommended or required readings
All teaching and practice material is available on the eCampus portal.
Assessment methods and criteria
- Personal presentation on a defined subejct (in English) during the theory lectures. The students may be questioned on any subject presented (either at the oral or written examination). The personal presentation is mandatory: a students who fails in delivering the presentation will not be admitted to the final examination.
- Oral examination on theory and practice (January).
- Weighing ratios: personal presentation: 20%; oral examination: 80%.
