In the future production of chemicals will likely change from large central plants using fossil fuels  to a decentralized plants where hydrogen produced from solar and wind power is reacted with CO2 from point sources or N2 from the atmosphere to synthesize chemicals locally. Such a transition necessitates improved catalysts to facilitate the synthesis of the chemical products at the milder conditions necessary to make decentralized production feasible.

The purpose of one PhD-project is to develop improved catalysts for methanol synthesis from CO, CO2 and H2 whereas the other project seeks to develop improved catalysts for ammonia synthesis from H2 and N2. This will be sought achieved through an increased understanding of how the interplay between catalyst structure/components and reaction conditions impacts the catalytic activity. This work entails synthesis of catalytic materials, catalytic tests in high-pressure flow reactors and catalyst characterization using a variety of experimental techniques.

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. The employed candidate will become part of the CHEC research group at the Department of Chemical Engineering, which carries out research on catalysis and high temperature processes.

Responsibilities and tasks 

  • Chemical synthesis of catalytic materials by wet chemistry techniques such as impregnation and precipitation.
  • Measurements of catalytic activity in flow reactors operating at high pressure including product characterization by gas chromatography and mass spectroscopy.
  • Commissioning and operation of a high pressure setup for thermogravimetric analysis for studying adsorbate coverages at real reaction conditions.
  • Kinetic modelling to analyse experimental results.
  • Performing catalyst characterization using techniques such as infrared spectroscopy, chemisorption and temperature programmed reaction or desorption.
  • Work with collaborators on catalyst characterization by electron microscopy and X-ray based techniques.

Qualifications
You must 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.

Approval and Enrolment
