Molten salts are ionic compounds that are in the solid phase at room temperature but become liquid at elevated temperatures. Molten salts are generally thermally stable, they have good heat transfer properties, they can act as solvents, and some salt melts have catalytic properties. At REALTEK, we investigate how these properties can be utilized when molten salts are used as reaction media for e.g. conversion of biomass to biofuels and CO2 capture. We work experimentally on a lab scale to understand the fundamental principles of these processes. In addition, we work with theoretical modelling to develop new phase diagrams for molten salts, as well as process simulations for future upscaling of the technologies. We collaborate with various partners and institutes, both in Norway and internationally.
