Expected start date and duration of employment

These are positions from 1 January 2027. There are two positions available, one position is for 2 years and one for 1.5 years.

 

Job description

The main responsibilities of the candidate will lie in:

• planning and execution of pilot scale HTL campaigns 
• carrying out wet-oxidation experiments in pilot scale
• supporting full scale HTL experimental campaigns with sampling, data analysis, process evaluation and product analysis
• developing new solutions and technologies for HTL product separation at pilot scale 
• Troubleshooting, modification, maintenance and carrying out improvements and upgrades on existing HTL-WO pilot plant
• chemical analysis of HTL products, data processing and analysis from experimental campaigns to produce scientific publications and reports 
• active participation in the project with all it’s partners, attend meetings, compile collaborative reports etc. 
• active participation in the supervision and training of MSc, BSc and PhD students

The work will expand on the on-going research using a state of the art, continuous, hydrothermal liquefaction (HTL) reactors at the Foulum Campus of Aarhus University. The HTL plant is integrated with Wet Oxidation (WO) plant is currently one of the largest worldwide in academic settings and allows testing of unique and novel ideas at a relevant scale for industry. The work will be carried out as part of a team working in hydrothermal processing and related technologies.
