Ammonia synthesis and separation at mild temperatures and pressures

Research area and project description
The PhD project will focus on the development of ammonia synthesis technology at mild pressures and temperatures. The main focus will be identification of best conditions for the synthesis to occurs and this includes i) optimal ratio of gases; ii) catalyst support geometry; iii) pressure & temperature and iv) nitrogen activation strategy.

Some specific tasks of the PhD position will include:
  • Help to develop the pressurized setup for continuous assessment of the technology performance.
  • Reactor optimization in terms of the composition of the inlet stream as well as nitrogen activation strategy.
  • Analysis of products (GC, MS, NMR, UV/Vis), Quantification of reaction rates, yields and energy efficiency.
  • Characterization of catalyst materials (XRD, TGA, BET, SEM-EDX) – pretest and postmortem analysis
  • Continuous data collection and visualization, preferably using Python/Matlab or other programming languages that allow for real-time data visualization/analysis.
  • Dissemination of results through both academic and non-academic channels.
  • Working in a consortium with external partners that will provide specific reactor components.

Project description
For technical reasons, you must upload a project description. Please simply copy the project description above and upload it as a PDF in the application.

Qualifications and specific competences
The applicant should have demonstrated excellence and have a relevant MSc degree in chemical engineering, chemistry or similar. The candidate should be a team worker. A “no-task-is-to-little for me” attitude, open discussion approach and strong ethics are required for this position.

Specific skills:
  • Well acquainted with Laboratory & Safety Procedures in a chemical lab and gas handling
  • Ready to learn completely new topics little to none covered in the literature – we will do this as a team and help you grow
  • Experience with reactor engineering, reaction kinetics, yields, selectivity and energy efficiency is a bonus. Otherwise we can help you master the topic, provided you convince us you are motivated to learn.
  • Good communication skills & publication experience is a bonus – but we can also help you develop these skills
  • Ability to work in a team and for a team.
  • Ability to work independently and deliver what has been agreed.

Place of employment and place of work
The place of employment is Aarhus University, and the place of work is Department of Biological and Chemical Engineering, Section for Process Materials and Engineering, Aabogade 40, 8200 Aarhus N., Denmark.

Applicants seeking further information are invited to contact:

  • Emil Drazevic, (main supervisor)
  • Jacopo Catalano, (co-supervisor)
