Postgraduate Course: Chemical Reaction Engineering (MSc) (PGEE10025)
|School||School of Engineering
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 10 (Postgraduate)
||Availability||Not available to visiting students
|Summary||The course will cover 4 topics:
1) Nonideal flow reactors: Define a residence time distribution RTD, E(t) and F(t) curves and the mean residence time. Diagnosis of reactor faults by RTD analysis. Modelling of complex behaviour by networks of ideal units. Effect on RTD of diffusion in packed beds. Predict effluent concentrations for multiple reactions.
2) Catalytic rates, catalytic CSTR and PFR reactors. Steps of catalytic reaction including external and internal mass transfer, adsorption, surface reaction and desorption. Models of heterogeneous catalytic kinetics: Effect of external heat and mass transfer resistances. Intrapellet conduction and diffusion. Thiele modulus and effectiveness factor. Extension to pellets of spherical and other shapes. Experimental evidence of diffusional effects: the Weisz modulus. External heat and mass transfer control: simultaneous heat and mass transport in external films: generalised nonisothermal effectiveness.
3) Further kinetics. Solid-fluid non-catalytic reactions and the shrinking core model and uniform conversion models. Design and operating implications of the basic science covered above.
4) Further reactor design: Design of multiphase catalytic reactors by considering multiphase reactions, catalysts decay, mass transfer and heat transfer. Suitable choices of reactor type and reactor design for exothermic reversible catalytic processes. Optimum temperature profile. Staged adiabatic catalytic reactors with intercoolers. Qualtitative consideration of other reactors. Multiphase reactions, both catalytic and non-catalytic, and the modelling thereof. This will include gas-liquid reactions, fluid-solid non-catalytic reactions and fluid-solid catalytic reactions. Qualitative consideration of 3-phase reactions.

On completion of this course, the student will be able to:
- Describe the mass& heat transfer and reaction phenomena occurring in heterogeneous reactions and model these.
- Make informed choices of reactor types for heterogeneous reactions
- Write and simplify appropriately the overall rate and balance equations for multiphase reactions
- Design reactors for heterogeneous reactions and optimise operating conditions
- Use RTD methods to diagnose nonideal flows in reactors and calculate conversions in nonideal reactors.
