Title: Biomass as an alternative reducing agent in non-ferrous metallurgy

The increasing consumption of carbon-based products in recent decades and their impact on the environment and climate change is becoming more and more significant. To curb this problem, the use of pyrolyzed biomass as a reducing agent substitute for carbon-based reduction processes can be part of the solution for a CO2-neutral metallurgy. The investigations include a possible use of pyrolyzed residual materials, such as waste wood, in aggregates based on solid-gas reactions, as well as in molten processes. During pyrolysis, a potentially usable pyrolysis gas is produced in addition to coal. Besides the use of coal, the dissertation also investigates the treatment of the gas and its use in various aggregates.
