abstract = {The challenges of future regarding the energy supply are
linked to the limitation of fossil fuels, the avoidance of
climatic relevant gases, and the worldwide increasing demand
for energy. Therefore, the future energy supply is
characterized by the increase of renewable energy: sun,
water, wind and biomass. Entrained flow gasification of
biomass is promising, since it is a highly efficient and
flexible process. Low-grade fuels are chemically transformed
at high temperatures (>1200 °C) and pressures (up to 80
bar) into synthetic fuels. The inorganics of the fuel are
converted into a slag, which forms a layer in the reactor.
The thermophysical and chemical properties of the slag are
defining the conditions and limitations of the gasification
process. In this study, the fundamental thermophysical
properties of bioliq slags are determined, in order to
describe the heat transfer and the flow of the slag across
the reactor by CDF-modelling of the bioliq-gasifier within
the HVIGasTech project. By using a high temperature
viscometer the viscosity and flow behavior of the slag were
determined. In addition, the density and surface tension
were measured by the sessile drop method. Thermometric and
calorimetric methods were used to provide a detailed view
onto the slags heat capacity and phase transitions.
Thermodynamic calculations using FactSage and an in-house
developed thermodynamic database for available solution
phases and compounds were performed to obtain information
about the ash-slag transformation.},
