Advanced Systems of Chemical Reaction Engineering

Objectives

The objectives of the course are:

• Instill a sense of the complexity of the catalytic process, namely that beyond the chemical reaction also mass transfer, internal or external, is crucial for the design of the reactor or to the prediction of its behaviour.

• Describe the main types of catalytic reactors and the mathematical models that allow to simulate its operation.

With the acquired knowledge the students should be able to:

• Propose mechanisms for a catalyzed reaction, deduce the corresponding kinetic models, choose the model that best fits the experimental data.

• Determine if a given catalytic process is limited by chemical reaction or mass transfer, intraparticle or external.

• Simulate the operation of a catalytic reactor, with the use of appropriate mathematical models.

Evaluation method

The practical works are carried out in working groups, being the evaluation made in workshops with powerpoint

Presentations. The practical part has the weight of 60% in the final grade. The individual work of the students is evaluated in two tests, which enter with the weight of 40% to the final grade.

Subject matter

Intraparticle gradient effects. Diffusion and reaction in the catalyst pellet. Non-isothermal catalyst pellet.

Heterogeneous catalytic reactors:

The packed-bed reactor. The packed-bed with axial diffusion.

The fluidized-bed reactor. The Kunii-Levenspiel model.

The multiphase reactors: slurry and trickle-bed.

Membrane reactors: inert and catalytic membranes.
