The CHEC research group at the Department of Chemical Engineering carries out research on catalysis and high temperature processes such as combustion, gasification and pyrolysis.

The gradual transition towards renewable energy sources necessitates new technologies for energy storage. One option is to store the energy in the form of chemicals by reacting CO2 emitted by local point sources with H2 produced from renewable energy via electrolysis. Here the production of methanol has a significant potential as a versatile liquid energy carrier, and it has been proposed that such a ‘methanol economy’ may play a vital part in the future society. While methanol synthesis from CO2 and H2 can be accomplished today with primarily Cu-based catalysts the existing processes require harsh reaction conditions (T > 473 K, P > 50 bar), but decentralized processes for energy storage purposes would benefit from being able to run at milder conditions. However, shifting the catalytic methanol production to milder conditions will require catalytic materials with higher activity at lower temperature. The methanol synthesis reaction is very sensitive to the metal-support combination, the types of catalytic sites generated by the catalyst synthesis procedure and to the reaction environment (i.e. the concentrations of H2, CO, CO2 and H2O). The purpose of this PhD-project is to develop improved methanol synthesis catalysts/process through an increased fundamental understanding of how these factors impact the catalytic activity. Particular emphasis will be on elucidating the extent of improvement that can be achieved when taking measures to ensure very dry reaction conditions to avoid any inhibition from the water produced in the reaction.

The PhD project is funded by the Villum Foundation Center for Science of Sustainable Fuels and Chemicals (V-SUSTAIN, grant 9455), and involves collaboration with several other DTU departments and foreign universities. 

Responsibilities and tasks

  • Chemical synthesis of catalytic materials by techniques such as impregnation and precipitation.
  • Measurements of catalytic activity at high pressure including product characterization by gas chromatography.
  • Kinetic modelling to analyse experimental results.
  • Characterization of catalytic materials by infrared spectroscopy, temperature programmed techniques and in situ measurements at synchrotron facilities.

Qualifications
Candidates should have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree. 

Preference will be given to candidates with a master's degree in chemical engineering or a similar degree with an academic level equivalent to the master's degree in engineering.
