Laboratory of Photochemical Reaction Engineering

Research Focus and Overview

The research group "Photochemical Reaction Engineering" was established in April 2018 as a part of the Institute of Chemical Engineering and works on fundamental investigations, optimization and design of photoreactors as well as photochemical processes. Optimization and design is based on fundamental knowledge of the photon fluxes in the reactors. For this, micro- and millistructured reactors, online-analytical methods, additive manufacturing and numerical simulations are applied as tools. Another topical focus lies on the application of light as tool for investigations in terms of reaction engineering.
