411-303 Reactor Engineering

610-141 and 610-142 Chemistry.

Basic concepts, ideal reactors, interpreting batch reactor data - no volume change, batch reactor data - complex reactions, batch reactor data - variable volume and differential method. Ideal reactor performance - batch reactor, ideal reactor performance - mixed flow reactor, ideal reactor - plug flow reactor, ideal reactor - performance comparison. Multiple reactors - mexed and plug flow reactors of identical size, multiple reactors - reactors of varying sizes, recycle plug flow reactor. Temperature effects - non-adiabatic operation, temperature effects - adiabatic operation, temperature instability. Non-ideal flow in reactors: residence time distributions, tracer tests, conversion in non-ideal reactors. Rate controlling mechanisms: film resistance control, chemical reaction control, surface and pore diffusion control, ash layer diffusion, shrinking core mechanisms, effectiveness factors and the Thiele modulus. Kinetic regimes for fluid-fluid and gas-fluid reactions.

One written 3-hour end-of-semestser examination (80%); a written 2-hour mid-semester test or a reactor design assignment (20%). An overall mark of 50% and a mark of 40% or more in the end of semester examination are needed to pass the subject.
