20 years Deutschmann group

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.


Tail pipe emission reduction of hybrid electric vehicles by periodic operation

In collaboration with the Waseda University in Tokyo and Japanese automobile manufacturers, a new process has been developed to increase the efficiency of the three-way catalytic converter in a hybrid-electric vehicle at low exhaust temperatures. Inhibition of the catalytic converter by blocking the active sites at low temperatures can be prevented by periodic lean-rich switches of the exhaust gas. The work contributes to a better understanding of periodic processes in exhaust gas catalysis and has recently been published in Appl. Catal. B: Environ. 14.02.2024.

Reducing C02 emissions in steel productionSMS group
Reduction of CO2 emissions in steel production

In cooperation with our industrial partner Paul Wurth SA we have demonstrated how 0.5% of the global CO2 emissions can be reduced with moderate investments by modernizing existing blast furnace technology for steel production.
In the process, CO2 is recycled from the blast furnace gas and converted with coke oven gas into synthesis gas, which can be used as a coke substitute in the blast furnace. It was demonstrated and validated in a pilot plant at the stock company of Dillinger Hüttenwerke (Dillinger) in Saarland. Further details are published in Energy Advances. 23.01.2024

Clean Circles
Iron as sustainable energy carrier

Iron is a promising, recyclable energy carrier that allows energy to be stored in large quantities and over long periods of time. The project Clean Circles investigates the iron cycle with an integrated approach in cooperation with the TU Darmstadt and further partners. The energy is stored by reducing iron oxides with green hydrogen. Based on experimental results, a reaction mechanism and accompanied kinetic data for this process were derived and recently published. 23.03.2023

ADCR Best Poster Award for RDM tools

At the Annual Digital Catalysis & Catalysis-Related Science Conference 2022 of NFDI4cat, Johannes Riedel and Hendrik Goßler received the Best Poster Award for the contribution “Automatization of Interdisciplinary Research Data Management for Catalysis”.

Strong presence at Annual Meeting on Reaction Engineering 2023

At the Annual Meeting on Reaction Engineering in May 2023 in Frankfurt, our newest research results were presented by a tandem plenary lecture (together with S.A. Schunk, hte/BASF) on Digitalization in Catalysis and Reaction Engineering, an oral (Lukas Wehrle on NH3 fueled SOFCs, see also) and eleven poster presentations.16.05.2023

20 years Deutschmann Group in Karlsruhe

In April 2003, Olaf Deutschmann became Professor for Chemical Technology at the Universität Karlsruhe (TH), now KIT, where his group’s work focuses is on the development of climate and environmentally friendly technologies in chemical industry, traffic, transportation, and the energy sector. 01.05.2023

Patent on electrochemical NOx conversion

A new patent on an electrochemical device for converting nitrogen oxides NOx into ammonia and/or hydrogen was recently granted to J. Dailly, A. Banerjee, O. Deutschmann. This invention is based on a strong collaboration between EIfER and KIT operating jointly the EnerMat Lab located at ITCP. The patent, WO2022171663A1, is now used by EdF. 24.05.2023

YounGeCatS Poster Workshop Award for Rinu Chacko

At the annual German Catalysis Meeting 2023 in Weimar, our PhD student Rinu Chacko received the YounGeCatS Poster Workshop Award for her research on Automating the Optimization of Catalytic Reaction Mechanism Parameters using Basin-Hopping. More information on the topic can be found in our recent paper in J. Phys. Chem. C. 31.03.2023

CRC/TRR150: Multi-Phase FlowsCRC TRR150
SFB/TRR 150 on multiphase flows extended by four years

After a successful evaluation, the SFB/TRR "Turbulent, chemically reacting multiphase flows near walls" started into the 3rd funding phase (2023-2026) on January 1, 2023. The working group of Olaf Deutschmann, the coordinator of TRR150 at KIT, is currently working on subproject B05 "Modelling and numerical simulation of multiphase chemical reactions". 01.03.2023
