Thermochemical Energy Conversion Laboratory (TEC-Lab)

The research area is within thermochemical energy conversion, mainly focusing on biomass but also on other solid and liquid fuels. The fundamental research is dedicated to gain deeper understanding of the fuel conversion processes as well as the ash and trace metal transformations at high temperatures.

Furthermore, applied and often multidisciplinary research is performed where competences within engineering, chemistry, physics, environmental science and medicine interacts. The overall aim with the research is to provide new knowledge that will help the society and industry to facilitate an increased use of new fuel materials, develop and improve industrial processes, avoid technical operational problems, re-cycle finite minerals, and minimize harmful by-products and air pollution.
