Dr. Bjarne Kreitz is an Assistant Professor of Chemical Engineering at Georgia Tech. Bjarne Kreitz received a B.Sc. and M.Sc. in Chemical Engineering from Clausthal University of Technology (Germany). He obtained his Dr.-Ing. in Chemical Engineering from Clausthal University of Technology under the supervision of Prof. Thomas Turek, working on the microkinetic investigation of the transient methanation with experiments and multiscale modeling. Dr. Kreitz conducted postdoctoral work at Brown University with Prof. Franklin Goldsmith with a Feodor Lynen Postdoctoral Scholarship from the Alexander von Humboldt Foundation. Before joining Brown, he worked briefly as a postdoc at the Karlsruhe Institute of Technology (Germany) in the group of Prof. Olaf Deutschmann.
The Kreitz Group unravels the detailed chemical kinetics of complex heterogeneously catalyzed reactions to advance crucial processes for a circular economy, including plastic waste upcycling, renewable fuel synthesis, and biomass conversion. The group uses a holistic chemical engineering approach consisting of:
- First-principles-based multiscale modeling
- Automated reaction mechanism development
- Kinetic experiments & theory-guided catalyst design
This holistic approach allows us to understand processes from the atomic to the reactor level, enabling the design of optimally performing catalysts and intensification of reactors. By combining advanced multiscale models with experiments, we will push the boundaries in the field to gain new insights into reaction mechanisms and achieve a more accurate understanding of the catalyst under working conditions.
Professor Kreitz's teaching interests focus on core chemical engineering principles imparted at both undergraduate and graduate levels. He emphasizes reaction kinetics, heterogeneous catalysis, thermodynamics, and multiscale modeling, fostering analytical and problem-solving skills. His instruction integrates theoretical concepts with practical applications, aiming to prepare students for diverse challenges in chemical engineering practice and research.
