PhD Candidate

About Me

Renée (1991) studied chemistry at the Radboud University, where she obtained both her Bachelor and Master degree. Previous projects include inline FTIR analysis in a microfluidic system, studying Grignard reaction intermediates, and the development of a gas-liquid microfluidic system integrated with a stripline NMR to hyperpolarize biomarkers for early medical diagnostics. Both projects were a collaboration between the Radboud University and FutureChemistry B.V. During an internship at the TU Eindhoven Renée worked on the reactor modelling of the Spinning Disc Reactor.  

In April 2015, she started as a PhD-student in the AMBER and MCS groups at the University of Twente, currently working on hydrogen production from biomass by Aqueous Phase Reforming (APR). A high temperature and pressure microfluidic platform will be developed in order to study the reaction thermodynamics and kinetics of this process. 

This project is part of the Multiscale Catalysis for Energy Conversion (MCEC) Gravitation program

Research

As the energy demand is still increasing and the fossil fuel supply is in rapid decline, research into new renewable energy sources and their production methods is urgently needed. Hydrogen is a promising alternative energy source that can be produced from biomass. Currently, pyrolysis, steam reforming and thermal liquefaction are the most common production methods. In 2002, the Dumesic group introduced Aqueous Phase Reforming (APR) as a less energy demanding alternative. In addition to a theoretical model, a high temperature and pressure microfluidic platform will be developed to study the thermodynamics and kinetics of aqueous phase reforming of biomass for hydrogen production.
