hela Sverige Luleå University of Technology is in strong growth with world-leading competence in several research areas. We shape the future through innovative education and ground-breaking research results, and based on the Arctic region, we create global social benefit. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has a total turnover of nearly SEK 2,1 billion per year. We currently have 1,900 employees and 18,700 students.
In the coming years, multi-billion investments will be made in large projects in Northern Sweden to create a fossil-free society both nationally and globally. Luleå University of Technology is involved in several of these cutting-edge research projects and in the societal transformation that they entail. We offer a broad range of courses and study programmes to match the skills in demand. We hope that you will help us to build the sustainable companies and societies of the future.Take the opportunity to study for a PhD in a dynamic, international research environment in close collaboration with industry and leading universities worldwide. We are looking for a PhD student in Process Metallurgy who will conduct research studies in the field of iron oxide reduction and carburization using alternative hydrogen carriers.
We "Process metallurgy research group" conduct research and education within the subject areas iron and steel metallurgy, base metal metallurgy, hydrometallurgy and recovery of minerals and metals from residual and end-of life products. The division has access to well-equipped laboratories for hydrometallurgical and pyrometallurgical studies, materials characterization and thermodynamics.
Subject description
Process Metallurgy deals with the sustainable extraction of metals from primary and secondary raw materials using both pyrometallurgical and hydrometallurgical processes.
Project description
A promising strategy for achieving net-zero CO2 emissions involves substituting fossil-carbon with green hydrogen. Sweden is leading several initiatives to implement this transition. However, challenges persist; replacing fossil carbon with hydrogen results in solid iron that lacks the necessary carbon content for refining, and steelmaking, thus requiring additional carbon for a feasible steelmaking process. Furthermore, potential hydrogen shortages present practical difficulties, making the utilization of alternative hydrogen carriers a viable solution. This project aims to tackle these challenges by simultaneously introducing fossil-free carbon into hydrogen-reduced iron. It will also explore the use of alternative hydrogen carriers.
The project will be based on experimental work on a lab scale, characterization of materials, theoretical calculations using thermodynamic and kinetic modeling tools and mapping of mate-rials and methods via literature and communication with experienced engineers and researchers in industry and at research organizations. The project will run in close collaboration with industry and senior researchers and PhD-students from both industry and academia will take part in the project.
Duties
You are expected to perform both experimental and theoretical work within your research studies as well as communicate your results at national and international conferences and in scientific journals. The majority of your working time will be devoted to your own research studies.
In addition, you can have the opportunity to try the teacher role. As a researcher, you work as a neutral party in many contexts, which provides a great opportunity to be involved in challenging development projects.
The research will include experimental work in the form of high temperatures experiments in lab scale, thermodynamic calculations and characterization of materials using various analytical equipment including Thermal analysis, XRD, SEM, LOM, etc. Some parts of the investigations might take place at the industry partners.
The PhD-studies is mainly carried out at Luleå University of Technology in Luleå, but experiments/investigations with industrial partners can also be included.
Qualifications
Applicants must have an MSc in Chemical Engineering, Sustainable Process Engineering, Engineering Chemistry, Materials Engineering, Metallurgy or comparable. Knowledge of metallurgical processes and mineral processing, experience of high-temperature experimental work and knowledge of reaction kinetics and thermodynamic modelling is desirable. Since much of the work will be done in close collaboration with other researchers and industry partners, where consideration must be given to practical conditions, the ability to work collaboratively in larger groups is an important asset. Applicants must have good proficiency in written and spoken English.
