The research at the Chair I of Technical Chemistry in the area of PtX focuses on the structural and kinetic characterization of catalysts for the hydrogenation of carbon oxides. In order to understand and to improve the hydrogenation catalysts in terms of their catalytic properties, comprehensive basic research on structure-activity relationships is necessary.

The hydrogenation reactions in the PtX processes are generally characterized by their high heat of reaction. Therefore, the kinetic description of product formation rates and, based thereon, application-related reactor modeling studies are of special interest.

Furthermore, COx streams are also often contaminated with traces of sulfur. For this reason, the investigation and description of deactivation processes caused by poisoning phenomena or by sintering due to the high thermal stress are further aspects that are addressed at the Chair I of Technical Chemistry. In order to understand hydrogenation catalysts in terms of their catalytic properties, comprehensive information on structure-activity relationships are indispensible.

At the Chair I of Technical Chemistry we pursue the approach to characterize interesting catalyst systems by means of static and transient analysis methods in different states, and thus to establish relationships between structural and morphological changes of the catalyst under reaction conditions and intrinsic activity. Based on these findings, existing catalysts can be further improved. Key approaches therein are the application of different catalyst preparation methods and the addition of promoters to the catalyst.
Knowledge of the reaction kinetics is essential for the design of chemical reactors in order to predict product and heat production rates. For this purpose, we use kinetic test stands to carry out measurements under conditions free from heat and mass transport limitations. The kinetic description is accomplished by parameter estimation of mechanistic approaches with the help of simulation software.
