Kongens Lyngby
We offer you an exciting opportunity to join DTU Chemical Engineering and partners in the HyProFuel project recently funded by Innovation Fund Denmark with the aim to develop and study catalytic processes to stabilize and subsequently convert biomass pyrolysis oil to a high quality liquid fuel for heavy transport and aviation by hydrotreating. You will be enrolled at DTU Chemical Engineering within the CHEC research center in a dynamic research environment. The project involves collaboration with Aarhus University, Copenhagen University, and several industrial companies, including Alfa Laval, Equinor, Kalundborg Refinery and Topsoe and will provide research with an international and practical impact.
Responsibilities and qualifications
Fast pyrolysis is a fairly simple and efficient way to convert solid biomass such as wood and agricultural waste to a liquid fuel in high yield. The liquid fuel however has adverse properties such as low heating value, low pH/high acidity and poor storage stability due to the high oxygen content. To obtain a high quality liquid fuel that can be used for heavy transport and aviation the oxygen must be removed by hydrotreating. A main challenge in standard hydrotreating of the pyrolysis oil is the poor thermal stability of the oil that leads to fast coking/deactivation of catalysts and plugging of the reactor. The aim of the PhD project is to develop a continuous catalytic process involving a stirred tank reactor that allows for un-interrupted production of oxygen-free high quality liquid hydrocarbon fuel. The intended hydrotreating process involves the formation of a slurry phase of pyrolysis oil and catalyst particles, where the highly reactive species causing the poor stability are converted to more stable species to obtain a high quality fuel.
The PhD study will be involved in the following tasks:
You must have a two-year master's degree (120 ECTS points) within chemical engineering, chemistry or a similar degree with an academic level equivalent to a two-year master's degree.
Knowledge/experiences in catalyst synthesis, testing and characterization and process optimisation will be an advantage.
You are high performing, visionary and thrive on turning exciting challenges into solutions based on curiosity and an open mind for entering new paths when necessary. You are able to drive things forward on your own, and you like to create results based on knowledge sharing and positive teamwork.
Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education .

Sustainable processes and products
At DTU Chemical Engineering we work systematically on making processes and products more sustainable. The petrochemical industry and the consumers of their products are major emitters of CO2 and this project will provide a process to convert agricultural waste to a sustainable liquid hydrocarbon fuel that can be used in hard-to-abate sectors such as heavy transport and aviation.
Technology for people
DTU develops technology for people. With our international elite research and study programmes, we are helping to create a better world and to solve the global challenges formulated in the UN’s 17 Sustainable Development Goals. Hans Christian Ørsted founded DTU in 1829 with a clear mission to develop and create value using science and engineering to benefit society. That mission lives on today. DTU has 13,500 students and 6,000 employees. We work in an international atmosphere and have an inclusive, evolving, and informal working environment. DTU has campuses in all parts of Denmark and in Greenland, and we collaborate with the best universities around the world.

The PhD study will be involved in the following tasks:
- Perform a literature study of biomass pyrolysis oil composition, catalytic pyrolysis oil stabilization and hydrotreating.
- Perform experiments to screen catalysts in a high-pressure batch autoclave reactor on conversion of model pyrolysis oils as well as real pyrolysis oil to identify promising catalysts for stabilizing the oil.
- Take part in setting up a high-pressure continuous stirred tank slurry reactor setup for integrated pyrolysis oil stabilization and hydrotreating.
- Perform experiments using the continuous slurry reactor using both model pyrolysis oils and real pyrolysis oils with the aim to identify reaction conditions and catalysts that allow continuous operation.
- Analyze, in collaboration with the project partners, the composition of the stabilized and fully upgraded pyrolysis oil in comparison with the untreated pyrolysis oil.
- Interact with the other partners of the project to reach overall project goals.
