Contents:

 Execution and evaluation of several experiments in chemical reaction engineering.

∗ Calculation of error propagation and error analysis

∗ Batch reactors – estimation of kinetic parameters for the saponification of ethylacetate

∗ Continuous stirred tank reactors, residence time distribution, reaction

∗ Continuous stirred tanks in series, residence time distribution

∗ Tubular reactor, residence time distribution, reaction

∗ Steady state Wicke-Kallenbach measurements of diffusivities in a catalyst pellet

∗ Interaction of reaction and diffusion in a catalyst particle, dissociation of methanol on zinc oxide

∗ Mass transfer in gas/liquid system

∗ Stability of a CSTR (hydrolysis of acetic anhydride)

∗ Computer simulation of various reactor systems

Learning Outcomes:

After successful completion of the experimental course, students should be able to execute experiments in Chemical Reaction Engineering, and crtically evaluate the data. In particular, the following experiments, covering a broad field of chemical reaction engineering,  should be executed:

- Stirred tank reactors - estimating of kinetic parameters of ethyl acetate saponification

- Continuous stirred tank reactor - Residence time distribution, conversion

-  Cascade of CSTRs - Residence time distribution

- Tubular reactor- Residence time distribution, Conversion

- Diffusion measurements inside catalyst pellets by  a  Wicke-Kallenbach Cell

-  Dissociation of methanol on zinc oxide

- Mass transfer in a gas/liquid reactor

- Stability of a CSTR (hydrolysis of acetic anhydride)

- Computer simulation of reactors

- Critical evaluation of experiments including error analysis and error propagation
