Elvira Mateos Mayo

I’m Elvira Mateos Mayo, and I finished my M.Sc. in Chemical Engineering at the University of Valladolid, (Valladolid, Spain) in 2013. My Master Thesis on “Polymerization of a binder for powder coatings in a continuous tubular reactor with supercritical CO2” was carried out in the Ruhr-University of Bochum (Bochum, Germany) between September 2012 and May 2013. Since July 2013, in collaboration with the Junior Professorship for Experimental Thermodynamics in Process Engineering of the Ruhr-University of Bochum, I’m doing a PhD in Rubotherm (Bochum, Germany) under the title “Measurement of Thermo-physical Properties and Sorption Isotherms Under Harsh Conditions Using Specialized Magnetic Suspension Balances”. This PhD position is part of the DoHip project.

My research is divided in two different parts:

1. The measurement of different properties (thermal conductivity, density, NIR spectroscopy, etc.) of gas mixtures at high temperature and pressure. The mixtures are generated in a Gas Mixture Generating and Sensor Calibration unit (GMG-SC), where the sensors are also placed. In the GMG-SC there are two different areas: the dosing and mixing area and the sensor area. The sensor area contains all the sensors apart from the densimeter, which is a magnetic suspension balance and is placed in the other area, since it works also as a dosing device. The GERG-2008 equation is used to calculate some of the measured properties and they will be also compared to some experimental data from the literature.

2. The adsorption of gas mixtures with a magnetic suspension balance and its prediction with different adsorption models for gas mixtures (Ideal Adsorbed Solution Theory, Real Adsorbed Solution Theory, Extended Langmuir model, Vacancy Solution Model, etc.). A great bibliographic research about these models is being carried out in order to find out which model is more suitable for the different adsorbents and adsorbates.
