Conversion and Reactor Sizing: Definition of conversion. Design equations for batch and flow systems. Reactors in series. Space velocity and space time. Rate Laws and Stoichiometry: Concepts of reaction rate, reaction order, elementary reaction and molecularity. Stoichiometric table. Reactions with phase change. Isothermal Reactor Design: Design structure for isothermal batch, plug flow and continuous stirred reactors. Design of multiple reactor systems. Pressure drop in reactors. Reversible reactions. Non-isothermal Reactor Design: The energy balance. Algorithms for non-isothermal plug flow and continuous stirred reactor design. Equilibrium conversion. Steady state multiplicity. Multiple Reactions: Conditions for maximising yield and selectivity in parallel and series reactions. Biocatalysis: Characteristics of enzyme catalysed reactions. Biocatalyst selection and production. Use of immobilised biocatalysts. Reactor selection and operation. External Diffusion Effects in Heterogeneous Reactions: Mass transfer fundamentals.
