Third-cycle subject: Materials Science and Engineering
Aluminum is one of the world's most widely used and recycled metals. Commercial primary aluminum manufacture involves reducing alumina to aluminium in a reduction/electrolysis cell. This process is achieved by running electricity between a negative cathode and a positive anode, both made of fossil carbon. The process is highly energy intensive, requiring 13,500-15,000 kWh per ton of aluminium. For the gas-powdered aluminum smelters of Europe, the corresponding carbon emission intensity is estimated to be 4-10 tons of CO2 per ton of aluminium. The secure supply of carbon anodes and the associated emissions from carbon anode consumption serve as the remaining major challenge for aluminium production.
Europe, especially the Nordic region, is rich in forest resources. Developing biomaterials derived from biomass as alternative sources of anode raw materials is ideal, which can avoid CO2 emissions from anode consumption.
The main scope of this position is to develop sustainable and highly efficient processes to upgrade bio-oil and biochar into high-quality carbon anode raw materials. Specifically:
- To develop a sustainable process for bio-oil upgradation to produce a high-quality binder used for carbon anode production;
- To develop a sustainable process for biochar upgradation to produce a high-quality dry material used for carbon anode production and as packing material;
Supervision: Weihong Yang, Docent, and Pär Jönsson, Professor, are proposed to supervise the doctoral student. Decisions are made on admission.
