Beschreibung

In view of the climate-related resource and energy transition and the high dependence on imports of
fossil raw materials, the development of new raw materials, such as biogenic or plastic residues, is of
utmost importance. In context of the chemical industry closing the carbon cycle is one key to a sustainable
future. One promising option is entrained-flow gasification for the conversion of pre-treated residues
into high-quality synthesis gas (H2 & CO), which can be converted into basic chemicals like methanol
through catalytic syntheses.
As the conversion rate defining step of the gasification process, thus the slowest step of the whole
process, the conversion of solid pyrolysis char into synthesis gas plays a decisive role for the design of
gasification reactors, especially for reactor concepts with short residence times such as entrained flow
gasifiers. For this reason the conversion of solid pyrolysis char into synthesis gas is investigated extensively
at the Chair of Energy Systems. Various influences such as the influence of pyrolysis conditions,
temperature, pressure, pore structure or catalytic components can be investigated.
The aim of this work is the experimental investigation of the influence of pyrolysis conditions on the
conversion behavior of pretreated biomass under gasification conditions, thus the thermal deactivation
behaviour. The results are to be compared with the literature and classified in the thesis.
