At the Faculty of Engineering and Science, AAU Energy, a position as PhD stipend is available within the general study program. The PhD stipend is open for appointment from 1 July 2023 or soon hereafter. The position is fixed for 3 years.

Job description

Aalborg University contributes to the knowledge building of the global society as well as the development of prosperity, welfare and culture of Danish society. This is accomplished through research, research-based education, public sector services and knowledge collaboration. AAU educates students for the future and activities are based on a dynamic and transformative collaboration with the surrounding community.

AAU Energy is a dynamic engineering research department in continuous growth and inspiring surroundings. AAU Energy has a very international environment and covers all areas of clean and sustainable energy systems of the future within electrical, thermal and mechatronic energy technology. AAU Energy has campuses in both Aalborg and Esbjerg, this position is located in Aalborg.

The mission is to be world leading in both research and research-based education of the energy engineers of the future. AAU Energy has approx. 300 employees of many nationalities, of which 25 are administrative staff. In addition, AAU Energy constantly has approx. 50-70 guest researchers from around the world.

Research and teaching are in the absolute world elite in the field of energy, and we have extensive and leading workshop and laboratory facilities, where research and innovation are carried out in direct collaboration with industry to a great extent.

AAU Energy offers this PhD position in the framework of the project CIRCULAIR, funded by the European Commission Horizon Europe program, in which the department is one of the main partners. The project concerns the production of sustainable aviation fuels (SAFs) through the hydrothermal liquefaction (HTL) of biomass and subsequent upgrading of the resulting bio-crude. The position is offered in relation to the research program "Advanced Biofuels" and the PhD Student will be positioned to the section for “Thermal Engineering”.

The offered position will focus especially on the upgrading of HTL bio-crude by means of catalytic hydroprocessing. Activities include hydrodeoxygenation and hydrodenitrogenation of HTL biocrudes from different biomass feedstocks in continuous lab-scale setups, the subsequent fractionation of process products and the full characterization of the resulting fuel cuts. Further treatments, such as hydrocracking, isomerization, and hydrofinishing, will be investigated as well, with the aim of obtaining SAFs compliant with current international specifications.

The ideal candidate must have a solid background within chemical, process, environmental, energy engineering or similar, or industrial/technical chemistry. He/she should have a strong interest in the topic and be willing to engage in experimental work on lab-scale production units. A highly independent and proactive attitude will be appreciated. Originality and independent thinking are strongly encouraged.

The application must include:

  • Letter of motivation
  • Diploma of master degree and academic transcripts
  • Curriculum vitae
  • Publication list (if applicable)
  • Project Description: the applicant must provide and upload a proper project description, which describes the applicant's initial thoughts and ideas related to the specific project applied for. This includes a brief state-of-the-art (including short list of references), a time schedule and how the applicant intends to shed light on the project objectives. The project description should have a length of 4-5 pages
