Thermodynamics of Mixed Phases and Interfaces
Interfacial thermodynamics
- Adsorption thermodynamics
- Simulation of gas-phase and liquid-phase adsorption and improvement of simulation algorithms
- Textural and energetic characterization of porous and/or dispersed solids
- Model development for the evaluation of gas and liquid adsorption isotherms
- Prediction of multicomponent adsorption
- Design of liquid-phase adsorption devices
Mixed phase thermodynamics
- Determination of VLE (vapor liquid equilibria) and LLE (liquid liquid equilibria) data in multicomponent systems
- Modeling and prediction of phase-equilibrium data with activity coefficient models (e.g. NRTL, UNIQUAC, mod. UNIFAC (Do)) and equations of state (e.g. CPA, SAFT, ESD)
Experimental methods
- Gas adsorption volumetry and manometry
- Liquid-phase adsorption device (self-construction)
- Microcalorimetry for determination of immersion enthalpies
- Circulation apparatus according to Röck und Sieg for measuring VLE
- LLE equilibrium measurements
- Concentration analysis using vibrational densitometry, gas chromatography, refractometry, Karl-Fischer and pH Titration, etc.
