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.
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
Unser langjähriger Mitarbeiter Dr. Günter Schoch ist am 7. August 2021 unerwartet im Alter von nur 68 Jahren verstorben. Herr Schoch hat sich nach seiner Promotion mit vielfältigen Themen aus dem Bereich der Chemischen Technik an unserem Institut beschäftigt. In den letzten Jahren vor seinem Ruhestand widmete er sich unter anderem erfolgreich der Herstellung von Kohlenstoffverbundwerkstoffen und der Reduzierung von Stickoxidemissionen aus Verbrennungsmotoren. Wir trauern um einen lieben Kollegen, den wir in guter Erinnerung behalten werden. 13.09.2021
Preparation of the reducing agent ammonia from urea-water sprays in SCR systems still represents a challenge in aftertreatment engineering as complex interactions of multi-phase physics and chemical reactions have to be handled. Increasingly stringent emission legislations and the ongoing development of fuel-efficient engines and close-coupled aftertreatment systems raise high demands to SCR systems. M. Börnhorst and O. Deutschmann have published a comprehensive review of advances and current challenges in urea SCR related research, now available in Progress in Energy and Combustion Science. 09.08.2021
Climate-friendly hydrogen-fueled internal combustion engines still produce NOx emissions because H2 is oxidized using air. The recent efforts of Borchers, K. Keller, P. Lott to clean these NOx emissions from H2-engines by the elegant way of direct H2-SCR are now published in Ind. Eng. Chem. Res.. Collaborating with many engine manufacturers and supplier industry we will continue to support the development of novel technologies for clean transportation vehicles. 12.05.2021
