We work on environmental and climate friendly novel chemical technologies. Our current research projects focus on the reduction of emissions of greenhouse gases (CO2, CH4, N2O) and local pollutants (NOx, particulate matter etc.) from processes in chemical industry, traffic, transportation, and the energy sector. Aside from developing advanced experimental tools for a better understanding of chemical reactors, we give a special emphasis on mathematical modeling and numerical simulation of technical processes.
The Deutschmann research group is part of the Institute for Chemical Technology and Polymer Chemistry (ITCP) and belongs to both the Faculty of Chemistry and Biosciences and the Faculty of Chemical and Process Engineering within Division I at KIT.
In catalysis research, we are closely linked to the IKFT and the Grunwaldt group. Our joint work on emission control is part of the Exhaust Gas Center Karlsruhe and the CRC 1441 TrackAct. In the ENERMAT laboratory, we study fuel and electrolysis cells. Within the CRC/TRR150 and Clean Circles, we collaborate with TU Darmstadt on reactive flowsand carbon-free chemical energy carriers, respectively.
An invited plenary lecture on “Heterogeneous Chemical Reactions - A Cornerstone in Emission Reduction of Local Pollutants and Greenhouse Gases” was given by Patrick Lott and Olaf Deutschmann at the 39th International Symposium on Combustion in Vancouver, Canada on July 26, 2022. The corresponding open access paper discusses emission control of natural gas and hydrogen fueled engines, use of CO2 in chemical and steel industry, hydrogen production by pyrolysis of methane, small-scale ammonia synthesis and use, and recyclable carbon-free energy carriers. 6.10.2022
Daniel Hodonj receives the „Emil-Kirschbaum-Studienpreis“ for the outstanding completion of his Master's degree in chemical engineering. He has been a doctoral student in our working group since February 2022 and conducts research on the topic of emission control of hybrid vehicles. 06.10.2022
At the Annual Meeting on Reaction Engineering 2022 in Würzburg, our PhD student Carola Kuhn presented her current research results on iron as renewable energy carrier within the project Clean Circles. She received the Young Talent Award for her presentation with the topic "Iron as recyclable metal fuel: Reaction kinetic analysis of iron oxide reduction with hydrogen". 01.10.2022
Oscar Furst, Junior Scientist in the Deutschmann research group, received a grant from ProcessNet within the NaWuReT call "Virtual Research Residency Reaction Engineering 2021". In cooperation with Dr. Yuqing Wang, Assistant Professor at the Beijing Institute of Technology, he is implementing a transient boundary layer solver for more accurate simulation of solid oxide cells, especially for their operation as clean energy storage devices. 12.01.2022
Computational Fluid Dynamics is a promising approach to support the design of industrial bubble columns operated at elevated pressures and temperatures. Nowadays such computations are often limited to lab-scale bubble columns and aqueous liquids at ambient conditions. Of special importance is reliable modeling of turbulence, which differs from that in single-phase flows. In a recent paper, Erdogan et al. present a systematic framework for the development of improved statistical turbulence models for bubble-driven liquid flows at technically relevant conditions. It combines scale-resolved (direct) simulations of swarms of millimeter-sized bubbles with scale-reduced simulations of an industrial pilot-scale bubble column, where numerical results for organic systems under elevated pressure are compared with measurements reported in literature. 12.01.2022
Technological challenges that commonly accompany high temperature systems prevented a commercialization of solid oxide fuel cells (SOFCs) in the mobility sector so far. Still, the traditionally used PEM fuel cells face severe thermal management issues that are critical for larger scale transport applications. Inspired by the rapid recent progress in SOFC electrode design and stack development, L. Wehrle et al. have published a detailed multi-scale modelling approach in ACS Environmental AU rigorously coupling single cell, stack and system level, to optimize the cell architecture of SOFCs and re-evaluate the technologies role for transportation. 10.12.2021
