Syllabus

Homogeneous reactor design and analysis-I: Ideal reactors, Review of isothermal design for batch, semi-batch and flow reactors, multiple reactions and reaction networks: Yield-selectivity concepts, Wei-Prater analysis for first order networks, reaction networks of general order, Reactor energy balance and its applications to reactor design and analysis.
Homogeneous reactor design and analysis-II: Non-ideal reactors- Review of the basic concepts of residence time distributions, single parameter models for real reactor behavior, macromixing and micromixing, segregated flow model and Zweitering's analysis of maximum mixedness, IEM and other models for micromixing.
Heterogeneous reactors-I: Gas-solid systems- Review of kinetics of gas-solid catalytic reactions with and without diffusion limitations, Reactor design for fixed and fluidized bed reactors, Selected case studies, Non-catalytic gas-solid reactions: review of kinetics reactor design case studies.
Heterogeneous reactors-II: Gas-liquid systems- Basic theories of mass transfer with chemical reaction model systems and model reactors, Reactor design for mechanically agitated and bubble column reactors. Selected case studies.

Course Objectives

  1. To develop critical and creative thinking skills related to advanced reaction engineering
  2. To train students how to select the suitability of reactors for given reaction kinetics for isothermal systems
  3. To study and design the non-ideal (real) reactors based on different models
  4. To provide advanced knowledge about chemical kinetics and reactor design of actual reactors, when reaction is affected by heat and mass transfer.

Course Outcomes

To master multi-phase reaction engineering, students need to understand the interplay between chemical kinetics and heat/mass transfer to build and solve reactor models. Specifically, by the end of the course students should be able to:
(1) Establish and follow a selection process to determine the most appropriate reactor type for a specific process.
(2) Design the reactor for single and multiple reactions for isothermal and non-isothermal systems.
(3) Analyse the behaviour of real reactors and design heterogeneous and multi-phase reactors.
