The Research on numerical modelling and simulation has become an important element for developing of validated models and for the design and the scale-up of reactors. In collaboration with the Institute for Technical Chemistry (ITC vgt) at Karlsruhe Institute for Technology and the Institute for Energy Process Engineering and Fuel Technology (IEVB) at Clausthal University of Technology, in particular, we are investigating and improving the description of sub-processes in entrained flow gasification :

• vaporisation of liquid biomass fuels,
• decomposition and heterogeneous gasification of both liquid and solid biomass fuels,
• homogeneous gasification,
• radiation,
• slagging.

Using numerical models of an atmospheric entrained flow gasifier (REGA) and of a high-pressurised entrained flow gasifier (bioliq EFG), we are testing and validating new models for entrained flow gasification of biomass fuels.
