Space- and time-resolved investigation of the gas phase and the active surface/bulk (C04)

• Subject Area: Technical Chemistry
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 426888090

This project focusses on the structural and concentration gradients that evolve during operation inside the channels and walls of monolithic catalysts in an emission control system. Therefore, new in situ techniques capable of simultaneously probing spatial and temporal changes in the gas phase and the catalyst will be developed. For the first time, non-invasive laser and X-ray based methods will be combined to investigate the catalyst using planar laser induced fluorescence (PLIF) and X-ray absorption spectroscopy (XAS). On basis of detailed reaction mechanisms and CFD simulations, the reactor behavior will be modeled and catalyst activation/regeneration strategies developed.
