Basis of chemical reaction engineering


Program (detailed contents):

Mass balance in reactional homogeneous systems. Continuous and batch systems. Transient and steady states. Progress reaction parameters. Global balances. Ideal reactor. Reaction rate, law for reaction rates and temperature influence. Identification of reaction rate laws.  Pseudo-first order approximation. Mass balances application in ideal reactors. Isothermal reactors design.



Mass balances in reactive systems.Reaction progress parameters and global balances. Reaction rate.Ideal reactors.Rate law determination.


Main difficulties for students:

To understand and to use some reaction progress parameters. The concepts of reaction rate, perfect mixing, plug flow. Problem resolution and balances establishment.


At the end of this module, the student will know and be able to explain (main concepts):

- Mass balances applied to reactors

- Reaction progress parameters

- Kinetic law of a reaction, kinetic order and constant, activation energy

- Continuous and batch stirred reactors

- Continuous plug flow reactors


The student will be able to:

- define a system, its boundaries, for a defined purpose; calculate all the molar fluxes (inlet, outlet, transformation, variation);

- write mass balances by using reaction progress parameters

- determine kinetic law for a homogeneous reaction from experimental data

- determine a kinetic constant for a temperature (Arrhenius law)

- choose the best ideal reactor for a homogeneous isothermal chemical reaction and calculate it (reactor design)

-  treat a general homogeneous isothermal problem of chemical reaction engineering

Needed prerequisite

Notion of balances. First order differential equation establishment and resolution. Linear regression.

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
