Setup and control of a test reactor for catalysis with optical access

CO2 Catalysis has been studied with Planar Laser Induced Fluorescence (PLIF) in combination with a mass spectrometer for a small, 23 cubic centimeters, cube shaped flow reactor. Both catalysis processes with one and with two catalysts inside the reactor have been carried out and analysed. Some results have been visualised by images showing concentration, given by the PLIF signal, of CO2 inside the reactor in two dimensions. This has the advantage of having two dimensional spatial resolution compared to only using the mass spectrometer. The experiments were also performed at almost ambient pressure (100 mbar).
