Description

The transition towards a climate-neutral energy system requires an increased use of renewable energy sources such as biomass. Biomass combustion plays an important role in sustainable heat and power generation; however, challenges remain regarding combustion efficiency and pollutant emissions, particularly nitrogen oxides (NOx). The reliable prediction and optimization of biomass conversion processes therefore require a detailed understanding of the fundamental fuel conversion mechanisms.

As the first step of the thermochemical conversion process, devolatilization plays a decisive role for the conversion behaviour of the fuel in the reactor. For this reason, the devolatilization is investigated at the Chair of Energy Systems separately in a wire-mesh reactor. Thus, various influences such as the influence of temperature, pressure or heating rate can be determined experimentally.

The aim of this work is the experimental investigation of the influence of temperature, pressure and residence time on devolatilization from pencil residue. The results are to be compared with literature and classified in the thesis.
