The project’s framework, financed via the Institute of Sustainable Process Technology and executed with a consortium of companies concerns pyrolysis and gasification of recycled polyolefin plastics. In this project TU Delft collaborates with a large national consortium of companies and universities. Within the project different recycled polyolefin plastic types are characterized via small-scale experiments regarding their decomposition behavior under well-controlled heating conditions to a wide range of final temperatures. In a second phase of the project, gasification tests are performed on the unique pilot-scale steam-blown bubbling fluidized bed gasifier (~10 kg/h capacity) available in the lab of the department of Process & Energy of TU Delft. The aim is to investigate the impact of different process parameters on the material conversion and product component yields of the different recycled plastic types. Evaluation of the results is supported by reactor modeling. The aim of the test programme is that the product spectrum will be such that production of plastic monomers -next to other chemicals- is enabled.The research group of Large-Scale Energy storage (LSE) in Delft has practical experience using steam/oxygen as oxidizing agents for solid fuel gasification as well as gas cleaning and upgrading of produced synthesis gas to chemicals and fuels. The laboratory of the department of Process & Energy is equipped with state-of-the-art thermo-chemical biomass conversion equipment and characterisation as well as analysis techniques (like TGA-FTIR, pyroprobe, HPLC/GC, ICP-OES, Karl-Fischer titration, SEM-EDX etc.) and has access to other equipment for elemental analysis and determining rheological properties of liquids.

You will be embedded in the Department of Process & Energy, within the section Large-Scale Energy Storage. The ambition of the Department of Process & Energy is to perform world class education and research in the area of process and energy for a sustainable development. We focus our research on the following areas: Energy Technology, Engineering Thermodynamics, Large Scale Energy Storage, Intensified Reaction and Separation Technology, Fluid Mechanics, and Multiphase Flow. We are situated in the Process and Energy lab, a modern and inspriring academic environment with unique experimental facilities. For more information, click here.

The section Large Scale Energy storage focuses its research on storage of electricity, on the scale of solar plants and wind farms and on process integration with thermo-chemical conversion of bio- and waste resources. It aims at bridging the gap between electricity load and demand, especially needed for highly intermittent energy sources like solar and wind. The main theme of the group is the conversion of power to preferably high energy density liquid fuels and chemicals where sustainably produced hydrogen is coupled to a (biobased) carbon source e.g. CO2, CO or C.


It is expected that the post-doc candidate has experience in experimental work regarding (thermo-chemical) fuel conversion. Excellent background is expected in the following areas: thermo-chemistry, chemical kinetics, thermodynamics, and physical transport phenomena (heat and mass transfer). Moreover, the candidate is expected to have good communication skills and to be a team player in a multidisciplinary setting. Furthermore, good oral and written knowledge of English is expected. TU Delft is a bi-lingual organization; good knowledge of the Dutch language is considered to be a positive aspect of your application.


TU Delft offers a customisable compensation package, a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers childcare and an international primary school. Dual Career Services offers support to accompanying partners. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities (salary indication: €3491-€4402 per month).
