要旨

This contribution presents a spatially resolving radiometric scanning method for the evaluation of the radiation field of photochemical reactors. By moving a calibrated spectrometer, a virtual canvas is created, capturing a UV/vis spectrum for every grid position. The measurements can be displayed as heatmaps, visualizing the received photon flux per measurement point or another property of the captured spectrum. This allows for an in-depth analysis of the radiation field to understand radiometric characteristics of the investigated setup. A perfluoroalkoxy alkane (PFA) capillary reactor system with one or two layers of capillaries was used to demonstrate the capabilities of the method. For a setup with two layers it is found that the first layer absorbs the majority of the incident photons (50%) whereas the second layer is absorbing 9%. The presented method allows for a sophisticated analysis of real photoreactors as the fundament for the development of highly efficient photoreactor designs and scale-up.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
