The Cluster of Excellence “Tailor-Made Fuels from Biomass”

The goal of the Cluster of Excellence Tailor-Made Fuels from Biomass (TMFB) is the interdisciplinary investigation of new synthetic fuels and chemicals generated from biomass. It aims at finding the best combination of selection and use of products and production processes. The research focuses on a holistic optimization with strong interaction of research projects in the fields of chemistry, engineering and economics.

Model-Based Automated Generation of Material Data for Liquid-Liquid Equilibria

The goal of this project is the model-based generation of material data for the characterization of complex liquid-liquid equilibria. Thereby, the reliability, accuracy, and labor saving aspects of automated experimentation are combined with model-based experimental analysis.

Biphasic systems of immiscible fluids are of paramount importance for technical application in the process industry. Nonetheless, the approach to solvent selection is usually carried out on a trial and error basis and guided by intuition of the experimentalist rather than by rational insight. The main reasons for this are that quantitative molecular understanding of the solute-solvent interactions is not developed today and that a considerable lack of reliable data on partition and solubility is apparent.
The realization of this project enables to unify both the automated experimentation and the physically motivated modeling. This overcomes the incessant lack of data for model validation and application needs. The experimental data are then used to parametrize thermodynamic models describing phase equilibria.
