The Chair I of Technical Chemistry deals with process and reaction engineering fundamentals and the mapping and optimization of complete chemical processes. In the field of PtX, the focus is on the structural and kinetic characterization of catalysts for the hydrogenation of carbon oxides.
Research primarily revolves around hydrogenation reactions of carbon oxides, particularly CO2 methanation and methanol synthesis. Intensive basic research on structure-activity relationships and deactivation processes is conducted at the Chair.
With the aid of simulation software (computational fluid dynamics), detailed studies are also carried out on heat and mass transfer limitations of catalytic reactions in new reactor concepts.
Technology development to improve power-to-methanol processes and Investigation of innovative reactor concepts
The Chair I of Technical Chemistry is involved in the characterization of catalysts, kinetic investigations under stationary, but above all dynamic reaction conditions, and the modelling of the kinetics of Cu/ZnO-based CO2 methanol synthesis. Computational Fluid Dynamics (CFD) is also being used to investigate other innovative reactor concepts and evaluate their potential for power-to-methanol processes.
Simulative investigation of the bio-chemical synthesis for the production of SAFs
The upscaling potential of various process routes is being investigated. The focus is on model development, process modelling and optimization for the bio-chemical synthesis to produce SAFs.
Flexible synthesis of light to medium alcohols and hydrocarbon energy carriers
The aim is to develop a scalable reaction pathway and catalyst system for the chemical storage of H2 in CO2-based alcohols and hydrocarbons. For this purpose, kinetic models for the hydrogenation of CO2 to alcohols and lower olefins are set up at the Chair I of Technical Chemistry. These models are used in conjunction with other process simulation tools to represent the overall process. Furthermore, kinetic studies of a Cu/ZnO-based catalyst for methanol synthesis from CO2 are carried out to elucidate deactivation mechanisms.
