PhD scholarship in Pyrolysis of Waste to Synthetic Fuels on Cement Plants

We offer you a unique opportunity to join DTU Chemical Engineering & industrial partners in the development and study of a new waste pyrolysis process yielding sustainable liquid fuels. You will be based at DTU Chemical engineering the CHEC research group in a dynamic research environment. The project will include collaboration with several industrial companies and will provide research with both an international and practical impact. The PhD project is part of a broader project team and you will work together with both industrial and academic experts in the field. The team will develop a new concept for producing synthetic liquid fuels from waste on cement plants.

Responsibilities and qualifications
The overall aim of the PhD project will be to optimize a pyrolysis reactor system that can be applied as an integrated part of the preheater system on a cement plants. This will mainly be done by using a laboratory set-up to investigate the influence of a broad range of waste types and operation conditions with respect to obtaining high oil yield and high oil quality. Samples from measurements campaigns at a FLSmidth owed pilot plant will furthermore be collected and characterized.

More specifically the position will be part of the following tasks:

    • Participate in the further development of a laboratory pyrolyzer and a tar collection system
    • Provide an assessment of pyrolysis oil quality as a function of waste type, raw meal calcination level and operation conditions
    • Collaborate with industrial partners on an up-scaling of the pyrolysis system
    • Obtain an improved fundamental understanding of pyrolysis when applying cement raw materials in the process
    • To interact with the other partners of the project for data analysis and design suggestions

You must have a two-year master’s degree within Chemical Engineering (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree. Knowledge and/or experiences pilot-scale reactors and pyrolysis will be an advantage.

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 the DTU PhD Guide.
