Advanced modeling of photocatalytic reactors

Updated: about 2 months ago
Deadline: 02 Mar 2021

The project aims at the development of a model for the rational design of photocatalytic reactors with complex geometries. Photocatalysis can be utilized in many applications, especially in the purification of gaseous or liquid streams since it promotes the oxidation of organic residues. A photocatalytic reactor, though, presents increased complexity over traditional catalysis, since it is not sufficient to have high surface area, but that surface needs to be activated by photons. View factors impose considerable limitations to geometry definitions, and there is always a trade-off between the quantity of available surface and its efficient illumination. The goal of the project is to use finite elements modelling to represent the phenomena occurring in a photocatalytic reactor (light radiation propagation, fluid dynamics and kinetics) and their interactions (particularly the relation between light intensity and reaction kinetics).
