Group Technologies for Solid Fuels Gasification (TSG)

The development and optimization of commercial/future gasifiers for the chemical conversion and utilization of carbon resources are conducted by the “Technologies for Solid  Fuels Gasification“ division. Accordingly, the influence  of feedstock type and quality and process  parameters such as temperature and pressure on  operation results are analyzed. Addressed processes are investigated by applying various computer-based  simulation tools as well as empirical non-dimensional  correlations. Calculation results are presented as thermodynamic indices, exergy analyses and multi- dimensional maps (ternary diagrams). Additional topics  include the gasification of low-quality (low-grade  and/or high-ash, high melting) coal, the development of novel/advanced gasification concepts as well as the optimization of established commercial  technologies.
