Course content
After an introduction (chapter 1), the course is divided in 3 parts, each dealing with a specific scale relevent to the reactor. A forth part, on bioreactor, ends the course
Part 1: chemical or biological reaction scale
Chapter 2: reminder on ideal reactors
Chapter 3: composed reaction scheme (serie, parrallel reaction, selectivity), enzymatic reactions (Michaelis-Menten, inhibitions)
Part 2: flow scale
Chapter 4: Residence time distribution and transfer function
Chapter 5: Application to reactors (compartment models, dispersive plug flow, short-circuits, dead volumen, tanks in serie)
Chapter 6: Impact on reactor efficiency (parrallel flow model)
Part 3: mass transfer scale
Chapter 7: reminder about mass transfer
Chapter 8: general strategy on coupling reaction and mass transfer
Chapter 9: reaction catalysed by solid (Thiele modulus, catalyst efficiency)
Chapter 10: reaction between a fluid and a solid (shrinking core model)
Chapter 11: reaction in non-miscible fluid (2 films models, Hatta number, acceleration factor, kLa)
Part 4 : bioreactors
Objectives (and/or specific learning outcomes)
The objective of this course is to lead the student to aprehend the tools to design non ideal chemical and biological reactors using a strategy based on the identification and the analysis, including mathematical modelling, of physico-chemical phenomena taking place in the reactor.
Prerequisites and Corequisites
Required and Corequired knowledge and skills
- Transport phenomena (mostly mass transport)
- Equilibrium thermodynamics
- Ideal reaction design
- Differential equation solving
- Numerical methods for equation resolutions
- (Bio) chemical kinetics
Teaching methods and learning activities
For each part, the basic principles and framework are given at courses. Classical theoretical calculations are realized in groups in seminar. The principles are then applied in exercices sessions of growing difficulty and nearing practical applications. Practical on computer (applying numericl methos in MS Excel ) allow to tackle a practical application from biotechnology, food industry or environment engineering.

Evaluation
Method(s) of evaluation
- written examination
- Oral examination
- Oral presentation
- Group work
written examination
- Open book examination
- Open question with developed answer
Oral examination
- Examination with preparation
- Open question with long development
Oral presentation
Group work
The evaluation combines continuous evaluation and a final oral exam.
The continuous evaluation is realized trough 3 contributions (one short oral presentation by 2, and two written report, also by 2 students) related to exercises on the course topic.
In january, the final exam is written. For this exam, a general problem dealing with the 3 first parts of the course is given. Theory questions for part 4 are also given.
In the second session, a similar exam, but oral, is organized
Mark calculation method (including weighting of intermediary marks)
The final mark is composed at 7/20 by the year mark coming from the continuous evaluation and at 13/20 by the exam mark (9 points for parts 1 to 3, 4 points for part 4).
The year mark is automatically transfered to the second session. The year mark is not transfered from one year to another.
